8 Ways To Prime Your Brain For Success

Our brains are essential for the quality of physical and mental performance. Smoking, excess alcohol, stress, or poor dietary habits, to name a few, can have a significant detrimental impact on our brain functionality. These habits also contribute to high blood pressure, cognitive decline, and dementia.

 

Fortunately, habits can be changed, and new strategies can be learned. The following tips can help to improve your brain and prime it for success.

 

Try the Mediterranean Diet (MeDi)

High-quality foods are essential for your brain health and physical fitness. The Mediterranean diet focuses on plant-based foods such as fruits and vegetables, nuts, seeds, beans, fish, whole grains, and healthy oils like olive and avocado oils. 

 

Based on a study of 502,536 participants, people who followed the principles of the MeDi had a 23% less chance of developing dementia. Also, research has found that the MeDi may improve your cognitive capabilities, such as memory.

 

Reduce Stress with Mindfulness Relaxation

Chronic stress can have a significant harmful effect on brain function. Yale Medicine defines chronic stress as “A consistent sense of feeling pressured and overwhelmed over a long period of time.” In today’s hectic world, there are many causes of chronic stress, such as life changes, an unpleasant career, or family dysfunction. When stressed, the brain increases glucocorticoid production, including the stress hormone cortisol. 

 

Mindfulness is a form of meditation that helps you focus on the present rather than dwelling on the past or situations causing you to worry. Other key concepts include paying attention to your surroundings, accepting yourself, and focusing on your breathing.

 

Be Physically Active

The Center for Creative Leadership asked over 1,500 executives how exercise impacts their performance. Approximately 90% said that physical activity “clearly impacts” their performance, 12% reported “some impact,” and no one reported zero impact.
Respondents reported that regular exercise improved mental clarity and focus, increased alertness, and improved problem-solving.

 

In addition to improving your brain, exercise has physical benefits such as lowering blood pressure and cholesterol, reducing anxiety, improving sleep, and strengthening your immune system.

 

Stay Mentally Active

 

The human brain must be exercised like a muscle; if your brain doesn’t get sufficient exercise, the result can be early cognitive decline. There are many activities that you can do to give your brain a workout, such as reading, learning a new language, playing games, or working on a jigsaw puzzle.

 

Sleep Well

The importance of sleep and its effect on your brain should not be underestimated. When you sleep deeply, the brain repairs itself and rejuvenates your immune system. When in REM (Rapid Eye Movement) sleep, the brain compiles details you learned during the prior day.

 

Inadequate sleep contributes to feeling exhausted, can cause concentration, mood, and memory disorders, and suppress your immune system.

 

If you cannot go to sleep or stay asleep, create a bedtime routine by going to bed at the same time nightly and waking up at the same time in the morning. Over time, this will help set your internal clock and become a regular sleep pattern. Also:

 

• Turn off your electronics at least two hours prior to bedtime. This includes cell phones, computers, and social media.
• Eliminate caffeine after 12:00 p.m. The most common sources of caffeine are coffee, tea, soda, and chocolate.
• Avoid eating before bedtime to prevent gastrointestinal issues that may keep you awake.

 

Avoid Smoking

While you may feel that cigarettes or cigars help to calm you and are pleasurable, there are risks to brain functionality. A study by the American Heart Association (AHA) found that smoking is associated with cognitive decline, leading to worsening performance. 

 

Be Socially Active

Social interaction can help to reduce stress and depression, preventing memory loss. Look for ways to interact with others, especially if you live alone. Brain atrophy has been linked to a lack of socialization. Being socially active can strengthen your brain health. 

 

Find Inspiration

The things we tend to take for granted can be inspirational and good for brain health. For example, Psych Central notes that watching the sunrise gives you a feeling of awe, bolsters your mood, and helps you to have a “big picture” mentality where we view situations broadly rather than focusing on limited details. It opens your mind to evaluating scenarios entirely rather than breaking them into detailed parts. 

 

People may also find inspiration from art, visiting a park, or watching the sunset.

 

Conclusion

 

A healthy brain keeps our sensory, cognitive, behavioral, emotional, and motor functions working smoothly. It is essential to develop good habits such as eating properly, being physically, mentally, and socially active, and getting sufficient sleep.

 

Practicing the preceding tips can boost brain health, priming your mind for success and well-being!

The Balancing Act: Letting Go Of The Need To Control Everything And Finding Harmony

As chaotic as modern life can be, you can find balance. It's difficult to get it right, especially when you're trying to embrace life's spontaneity while also creating an efficient routine to maximize your time and opportunities. 

 

There's a big part of it that requires control, the problem is that the desire for too much control can stress you out and make you incredibly anxious. This need for too much control steeps you into a state of perpetual tension. Here, we talk about the balancing act and the art of letting go. 

 

Control is an Illusion 

 

Control is an illusion, it's the idea that you can dictate all of the outcomes throughout your life. There are, of course, certain things you can control. If you're getting a degree, license, or qualification in something, you can control the level of study you put in for the testing process. That's in your hands. 

 

Not everything is that simple, though, and the reality is most things in life are inherently unpredictable. So, the more you cling to this illusion of control, the more stressed out you become and the more frustrated and disappointed you feel when things don't go your way. Accept that there are limits to what you can control. 

 

Embrace the Uncertainty 

 

Some of the beauty of life lies in its unpredictability, some of the greatest moments of your life probably came from nowhere. Embrace that uncertainty, it might be a shift in your perspective, but it gives you the freedom to navigate new situations with more grace and patience. Don't resist change, don't avoid unpredictability, lean in, and recognize there's a chance for growth. 

 

Cultivate Mindfulness

 

Mindfulness is a useful tool and a powerful one in your journey to let go and find balance. By cultivating a level of mindfulness, you are detaching yourself from the desperate need to control everything. Focus on the present, find peace, and enjoy clarity in the here and now instead of getting caught up in the past or obsessing about the future. 

 

Identify Your Areas of Control 

 

As important as it is to understand how limited your control is, it's just as important to recognize your areas of control. When you understand what you can control, you can focus your efforts and energy on those areas to maximize that control. It also gives you a deep sense of empowerment, without the added burden of managing something that's unmanageable. 

 

The Process

 

While some people think letting go is showing weakness, the reality is it's recognition that you are human. Sometimes, you have to surrender to the process and let life do what it's going to do without trying to control every single detail. You can't micromanage, so don't bother trying!

 

The Joy of Imperfection 

 

There are two big issues that plague us – the need for control and perfectionism and they go hand-in-hand. When you embrace imperfection, you're letting go of control – you're letting go of the idea that everything needs to be flawless and freeing yourself from the unrealistic expectations society places on you. Find joy in those imperfections, that's where you can flourish. 

 

Embrace Self-Compassion 

 

Self-compassion is the final piece of the puzzle because you can't let go and find balance without it. You need to recognize that it's okay that you don't have it all figured out, that it's okay if you're still making mistakes – it's all part of the human experience. `Treat yourself with kindness in those moments of uncertainty. 

 

Final Thoughts

 

There is a delicate balancing act between leaning into life and letting go of control. You have to make a conscious effort to loosen your grip on those reins, but in doing so, you will finally be able to find harmony in life! The biggest secret out there is you'll find harmony in this moment, which means letting go and enjoying every moment for what it is. 

 

Forgiveness As Liberation: The Art Of Letting Go Of Resentment

Everyone has experienced conflict and hurt from other’s words or conduct. Suppose a co-worker got credit for your work, or you were bullied as a child. Incidents such as these leave you feeling resentful, bitter, and angry long-term if not resolved. Unresolved resentment can have a significant impact on your health.

 

“There is an enormous physical burden to being hurt and disappointed,” says Karen Swartz, M.D., director of the Mood Disorders Adult Consultation Clinic, Johns Hopkins Hospital. Chronic resentment can affect blood pressure, heart rate, and immune response, raising the risk of heart disease, depression, and other conditions.

 

On a positive note, forgiveness helps to calm your stress level, resulting in better physical and mental health.

 

Why Do We Feel Resentment?

 

When someone hurts us, we may feel a range of negative emotions such as sadness, hostility, or even hatred. When we don’t let go and forgive, we are consumed with those pessimistic feelings, affecting our self-esteem and well-being. If you are suffering from chronic resentment, you can learn to be forgiving; forgiving is a choice.

 

What is Forgiveness?

 

Psychologists commonly define forgiveness as “A conscious, deliberate decision to release feelings of resentment or vengeance toward a person or group who has harmed you, regardless of whether they actually deserve your forgiveness.” 

 

Bear in mind that you can forgive without denying or forgetting the wrongdoing against you. You are not required to mend a bad relationship or release others from legal liability. 

 

How to Forgive

 

Choose Forgiveness

 

First, you need to decide whether you choose to forgive. While you don't have to forgive, it is to your benefit to do so. Research by the Annals of Behavioral Medicine shows that increased forgiveness decreases perceived stress and improves mental and physical health.

 

Leverage the Power of Positive Thinking

The effect of negative thinking and feelings is unhappiness. In order to heal, be consciously aware when you’re burdened with pessimistic thoughts. Use positive self-talk to replace the distressing thoughts. For example, you may want to retaliate against the person who hurt you. Remind yourself that you will be fair with that person and that you will not mirror their harmful actions.

 

Change Your Perspective

Think about the other person to understand their actions better. Was the person hurt by others or mistreated? Is the person going through a difficult time? That person may be in pain, struggling with chronic resentment, affecting their behavior with others. Look at the person with a compassionate perspective to gain insight. You don’t need to excuse the person, but you can forgive and move forward.

 

Acknowledge and Accept Your Pain

Recognize the hurt you’re feeling; don’t avoid it. Explore the emotions you’re experiencing and accept the pain. Psychology Today reports “Pain is actually a necessary part of happiness, and research shows that it can lead to pleasure in several ways.” For example, pain helps you recognize happiness; otherwise, you wouldn’t recognize it as happiness. Also, relief from pain is pleasurable and increases your happiness.

 

Conclusion

When someone hurts us, we may have a difficult time letting go of the feelings of resentment. Chronic resentment harms our well-being in many ways. On the other hand, forgiveness frees us from negative emotions, calms our stress levels, and brings us peace of mind. While we don’t have to deny or forget the offense against us, letting go of resentment and practicing forgiveness is liberating and necessary for optimal wellness.

"I think the first step is to understand that forgiveness does not exonerate the perpetrator. Forgiveness liberates the victim. It's a gift you give yourself." - T.D. Jakes

5 Ways To Stop The Negative Effects Of Social Media

There’s no denying that there’s a lot of good that we can take from social media. The most important is that it allows us to connect with family and friends. We can also preserve memories, share things that interest us, and it’s also a great place where we can learn new, interesting things like a new skill or talent.

 

Not only that, but these platforms offer information in a myriad of ways. For example, YouTube has full-length tutorials on how to do all sorts of things, from fixing the kitchen sink to doing a macramé plant holder.

 

Pinterest is also just as popular for its vast array of data. Yet, it focuses more on pictures and short reels.

 

Then, you have Instagram, TikTok, Facebook, Twitter, and others that provide an image picture or brief video content along with a short-written explanation.

 

Nevertheless, with all these benefits that social media seems to provide, it also has its disadvantages. Research shows that spending too much time on these platforms can lead to increased stress, loneliness, isolation, and depression.

 

So, how can you take the good while minimizing the negative effects of social media? Here are five things you can try today to help you do just that.

 

Customize Your Feed

 

Unfollow and remove negative or fearmongering pages. Delete toxic friends. Limit who views and comments on your posts.

 

It sounds drastic but tell yourself that it’s perfectly okay to keep a small circle of virtual friends.

 

Instead, you can replace them with accounts that make you feel good about yourself. Look for influencers who embrace their natural beauty. Follow people who are constantly spreading positive words of motivation across their feeds.

 

Regulate the When

 

Many of us set alarms on our devices. So, it’s become second nature to immediately reach for your phone as soon as you wake up, which leads to getting bombarded with a stream of news, updates, and inconsequential posts.

 

This only leads to exacerbating your stress and anxiety, which isn’t exactly the best way to gear up for a new day.

 

Instead, consider integrating more mindful routines around two or more screen-free activities like journaling, meditating, and practicing gratitude.

 

When you do start scrolling through social media, set a time limit on how long you spend on each app. One study found that a healthy amount of time would be between an hour to two hours in total for the entire day.

 

Just make sure you split it up into 15- to 30-minute increments throughout the day. For example, you can schedule 30 minutes after breakfast, 30 minutes during your lunch break, another 30 minutes in the afternoon, and 30 minutes about three hours before bedtime.

 

Turn off Notifications

 

Just because you have your phone on you all the time doesn’t mean you have to be available 24/7. It’s okay to disconnect from the virtual world at certain times during the day.

 

Getting inundated with notifications from various social media platforms can be overwhelming. It’s especially infuriating when you’re trying to work, study, or just enjoy a few minutes of peace and quiet.

 

Remind yourself that social media apps are designed to hijack your attention and get you to spend as much as possible on them so they can generate revenue from ads.

 

The most effective you can do to reduce the amount of time wasted on these apps is to switch off notifications as many times as you need during the day.

 

Be Critical

 

Always be critical of social media. Remember that all the posts and reels you’re seeing are someone’s best moments of the day, maybe even the whole week.

 

They’re only showing you what they want you to see, which is why they probably have some time to prepare for it and set everything up. So, it’s not exactly their typical day-to-day life that they’re displaying.

 

Detox

 

Try this the next time you feel you’ve had too much social media exposure: nothing.

Put the phone down and just be in the moment. Take a look around the room. Notice how the light shines through the window. Listen to the different sounds around you.

 

Full disclosure: you’ll probably start to feel uncomfortable after about five seconds. But that’s okay.

 

As you try to hang on for a full 60 seconds, think about why you’re uncomfortable. Knowing the reason can help wean you off your addiction to social media as well as the notion that you simply must have your phone in your hand all the time.

 

Instead, why not do something more constructive with your time? You can learn a new skill, revisit an old hobby, read, exercise, go for a walk, journal, draw, paint, or play a musical instrument, and more!

 

So, find what you’re passionate about. Then, spend time doing more of that instead of mindlessly scrolling through social media.

 

Baggage Be Gone: How To Let Go Of Emotional Weight

Per Sabrina Romanoff, a clinical psychologist, in an article published in Very Well Mind, emotional baggage “...refers to unfinished emotional issues, stressors, pain, and difficulties we’ve experienced that continue to take up space in our minds and affect our present relationships”

 

In other words, the psychological wounds we carry prevent us from living peacefully. Worse, emotional baggage can lead to ongoing stress and depression, and even begin to create physical issues. It’s not uncommon for people with lots of emotional baggage to experience panic attacks, heart palpitations, shortness of breath, and insomnia. 

 

Though we all carry some sort of emotional baggage throughout our lives, the happiest people are those who learn to control their emotional baggage instead of allowing it to control them. Of course, this is easier said than done. 

 

However, we have some helpful tips on how to let go of the emotional weight so you can start living freely. 

 

Identify What Caused It

 

Think of addressing your emotional baggage like mold remediation. Though your goal is to treat the mold, you first have to identify what caused it because it doesn’t just appear out of nowhere. The same concept applies to this. 

 

If you carry guilt or commitment issues - two very common types of emotional weight - then it’s not enough to just accept what happened or just jump into a relationship to prove you’re okay. Doing so may lead to temporary satisfaction, but nothing sustainable. Instead, you need to figure out why these feelings exist. Like the mold, you have to get down to the real cause and treat that before you can address anything else. 

 

For example, the root cause of commitment issues could be anything from fear of rejection or abandonment that stems from childhood or having experienced abuse in a previous relationship. By identifying the root cause, you can then address its symptoms.

 

Seek Therapy 

 

If you’re dealing with an emotional weight that’s beginning to get too heavy to carry, then one way you can start to let go is by letting someone else help you with the load. One way to do this is by seeking the guidance and support of a licensed therapist.

 

In therapy, you can address your past and how it’s currently infringing on your life. Furthermore, you’ll get a chance to address what you don’t like about the baggage, which can help motivate you to unpack it. 

 

Though therapy has become a little more expensive in recent years, there are affordable options through apps like BetterHelp. Many therapists also work on a sliding scale or even on a pro bono basis, so don’t be afraid to ask about those options. 

 

Learn to Sit With Uncomfortable Emotions

 

One of the main reasons why we tend to hold onto emotional baggage is because we don’t take the time to process it. 

 

Though everyone has their coping mechanisms, it’s never healthy to avoid your emotions or try pushing them under the rug. Even if you do that - and think things are okay for a little while - they will eventually pop up again the next time you encounter a similar emotion or situation. 

 

A good example would be grief. If you don’t take the time to feel sad and angry, you may not be equipped to take care of yourself or be a strong support system for others when they, too, eventually encounter loss. 

 

It’s going to be uncomfortable but sit with your sadness when you start feeling sad. Cry when you feel like crying. Scream when you feel angry. Starting out, and to make this easier, you can even set a timer so you’re only dealing with these negative emotions within a window you feel comfortable with. 

 

When you do this, you take the power back from these emotions, so they no longer control you. With enough practice and time, you’ll be able to encounter a sad moment instead of allowing the emotional weight of a trigger to ruin your entire day. 

 

These are just a few of the best ways you can begin to let go of emotional baggage. While we all have emotional weight, you don’t have to let it rule over you. There’s a grace in allowing yourself to be human and remember that what words or actions hurt you in the past don’t have to be your identifiers forever. 

 

15 Super Mental Health Tips

Prioritizing mental well-being is more crucial than ever. With increasing external pressures and internal challenges, it's vital to have strategies in place to maintain and enhance our mental health. While professional help is essential for severe mental health issues, everyday practices can significantly boost our overall mental wellness. 

 

This article delves into 15 super tips, grounded in both ancient wisdom and modern research, to help you navigate the pathways of your mind. 

 

Practice Mindfulness Meditation

 

Mindfulness meditation is a practice that focuses on the present moment without judgment. It's a technique that has its roots in ancient Buddhist traditions but has gained significant attention in modern psychology for its benefits. 

 

Research shows that practicing mindfulness can reduce stress, improve concentration, and even increase one's overall happiness.

 

Taking just a few minutes each day to sit quietly, breathe deeply, and focus on the present can make a significant difference in one's mental well-being.

 

Stay Physically Active

 

Exercise isn't just for physical health; it plays a pivotal role in mental wellness, too. Regular physical activity can help alleviate symptoms of depression and anxiety. 

 

When we exercise, our body releases endorphins, which are natural mood lifters. Whether it's a brisk walk, a yoga session, or a high-intensity workout, find an activity you enjoy and make it a part of your routine.

 

Get Adequate Sleep

 

“While insomnia can be a symptom of psychiatric disorders, like anxiety and depression, it is now recognized that sleep problems can also contribute to the onset and worsening of different mental health problems, including depression, anxiety, and even suicidal ideation.” (https://www.columbiapsychiatry.org/)

 

Sleep is essential for mental health. Lack of rest can exacerbate feelings of stress, anxiety, and depression. It's crucial to establish a regular sleep routine, ensuring you get at least 7-9 hours of sleep per night.

 

Avoid screen time at least an hour before bed, keep your bedroom dark and cool, and try to go to bed and wake up at the same time every day.

 

Connect with Loved Ones

 

“When people are socially connected and have stable and supportive relationships, they are more likely to make healthy choices and to have better mental and physical health outcomes. They are also better able to cope with hard times, stress, anxiety, and depression.” (Centers For Disease Control)

 

Human beings are social creatures. Connecting with friends, family, and even pets can provide emotional support and reduce feelings of loneliness and isolation. 

 

Spend quality time with loved ones, engage in meaningful conversations, and seek support when needed. Remember, it's okay to lean on others when you're feeling down.

 

Limit Alcohol and Caffeine Intake

 

While a glass of wine or a cup of coffee might seem like a good idea at the moment, excessive intake can negatively impact your mental health. 

 

Both alcohol and caffeine can disrupt sleep patterns and exacerbate anxiety. It's essential to consume them in moderation and be aware of their effects on your mind and body.

 

Set Realistic Goals

 

Setting achievable goals can give you a sense of purpose and direction. Start with small steps and celebrate your achievements along the way. 

 

Whether it's related to your career, personal life, or hobbies, having clear goals can act as a motivating force and enhance your self-esteem. Remember, it's okay to adjust your goals based on changing circumstances or feelings.

 

Take Breaks and Manage Stress

 

It's essential to recognize when you're feeling overwhelmed and give yourself a break. Whether it's a short walk, a day off, or a vacation, taking time to relax and rejuvenate can significantly benefit your mental health. 

 

Incorporate stress-reducing activities into your routine, such as deep breathing exercises, journaling, or listening to music.

 

Maintain a Balanced Diet

 

What you eat can significantly influence your mental health. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can boost your mood and energy. 

 

Avoid excessive sugar and processed foods, which can lead to mood swings and feelings of fatigue. Drinking plenty of water also helps in maintaining optimal brain function.

 

Limit Exposure to Negative News

 

While it's essential to stay informed, constant exposure to negative news can take a toll on your mental well-being. Set boundaries for how often and when you consume news. 

Consider designating specific times in the day to check updates and avoid doing so right before bed. Remember to balance the intake with positive stories and news as well.

 

Seek Professional Help When Needed

 

There's no shame in seeking help. If you feel persistently sad, anxious, or overwhelmed, it might be time to consult a professional. 

 

Therapists, counselors, and psychiatrists can provide valuable insights, coping strategies, and support. Remember, taking the step to seek help is a sign of strength, not weakness.

 

Limit Screen Time

 

Spending excessive time in front of screens, whether it's for work or leisure, can negatively impact mental health. Studies have shown that prolonged screen time can lead to symptoms of depression and anxiety. 

 

It's crucial to take regular breaks, perhaps following the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. Also, consider setting a screen curfew before bedtime to improve sleep quality.

 

Engage in Creative Activities

 

Engaging in creative activities can be therapeutic. Whether it's painting, writing, crafting, or playing a musical instrument, expressing oneself creatively can provide a sense of accomplishment and act as an emotional outlet. 

 

The good news is that you don't have to be an expert; the process is more important than the end product.

 

Practice Gratitude

 

Focusing on positive aspects of your life and practicing gratitude can significantly boost mental well-being. Consider maintaining a gratitude journal, where you jot down things you're thankful for each day. 

 

Studies have shown that practicing gratitude can lead to increased happiness and reduced depressive symptoms.

 

Avoid Drugs and Substance Abuse

 

While some might turn to drugs or alcohol as a coping mechanism, substance abuse can exacerbate mental health issues. It's essential to be aware of the consequences and seek support if you find yourself relying on substances for emotional relief.

 

Educate Yourself

 

Understanding mental health, its challenges, and various coping mechanisms can empower you to take better care of yourself. 

 

Numerous resources, both online and offline, provide valuable insights into mental well-being. Educating yourself can also help in reducing the stigma associated with mental health issues.
