Neuroscientists Explain How Running Changes Our Brains And Affects Our Thinking

Neuroscientists Explain How Running Changes Our Brains And Affects Our Thinking

“Running is a road to self-awareness and reliance – you can push yourself to extremes and learn the harsh reality of your physical and mental limitations or coast quietly down a solitary path watching the earth spin beneath your feet.” by Doris Brown Heritage. Are you familiar with this feeling? Do you gain insight into your emotional and physical self while you run? Do you enjoy the feeling of the wind against your face and the freedom of being outdoors alone with your thoughts? You may feel that after a good run your mind is clear and ready to absorb information. You can also find that your outlook is more positive after a run and that things that were troubling you no longer feel so bad. Well, your feelings have a scientific basis. Research conducted in the field of neuroscience shows the effects aerobic exercise have on cognitive clarity and emotional well-being.

New Neurons Would Be Created

It used to be accepted that we were born with a certain amount of neurons and that by the time we became an adult no new neurons would be created. This however, has been proven to be incorrect. Through research on animals it has been discovered that new neurons are continually produced in the brain throughout our entire life. Karen Postal, president of the American Academy of Clinical Neuropsychology says that the only activity that is shown to trigger the birth of these new neurons is vigorous aerobic exercise. “If you are exercising so that you sweat – about 30 to 40 minutes – new brain cells are being born” says Postal. So sweating it out on the treadmill or out in the open is doing your brain a lot of good and helping it stay mentally healthy for years to come.

People Who Run Can Recover From Negative Emotions More Quickly

In a study by Emily Bernstein and Richard McNally it was found that aerobic exercise may help reduce negative emotions. Bernstein is a runner and she said “I notice in myself that I just feel better when I’m active”. She wanted to find out why this was the case and to know exactly the effect that exercise has on us. The study set out to look at the way exercise changes the way people react to their emotions. Participants were told to stretch or jog for 30 minutes and were then were shown a sad movie; the final scene of the 1979 film The Champ. The participants then reported their emotional responses. It was found that those who had run for 30 minutes recovered more quickly from their sad emotional experience than those who had just stretched.

Working Memory Would Be Enhanced

A recent study by Lin Li et al titled: “Acute Aerobic Exercise Increases Cortical Activity during Working Memory: A Functional MRI Study in Female College Students”  looks at the effect of acute aerobic exercise on cognitive function. Their study looked at the effect of a session of acute aerobic exercise on working memory. Fifteen young females participated in the study. There were scanned, after an acute exercise session, using a MRI (magnetic resonance imaging) while they performed a working memory task. It was found that the cortex and the left frontal hemisphere showed signs of improvement of control processes. From these findings the researchers noted that this indicates: “acute exercise could benefit working memory at a macro-neural level.” Thus, the study shows a connection between aerobic exercise and improvement in memory.

Summation

Next time you are out for a run know that you are doing yourself a world of good. Not only are you aiding your brain on a neurological level you are also working to improve your emotional health. Your cognitive abilities such as memory will be improved and your outlook on life will probably be more positive. If you don’t already run, then you may want to take out those old running shoes and give them a try.

How to Say No When You Say Yes Too Often

How to Say No When You Say Yes Too Often

Do you say yes so often that you realize you aren’t really happy about this, wondering how to say no to people?

For years, I was a serial people pleaser. Known as someone who would step up, I would gladly make time especially when it came to volunteering for certain causes. I proudly carried this role all through grade school, college, even through law school. For years, I thought saying “no” meant I would disappoint a good friend or someone I respected.

But somewhere along the way, I noticed I wasn’t quite living my life. Instead, I seem to have created a schedule that was a strange combination of meeting the expectations of others, what I thought I should be doing, and some of what I actually wanted to do. The result? I had a packed schedule that left me overwhelmed and unfulfilled.

It took a long while but I learned the art of saying no. Saying ‘no’ meant I no longer catered fully to everyone else’s needs and could make more room for what I really wanted to do. Instead of cramming too much in, I chose to pursue what really mattered. I started to manage my time more around my own needs and interests. When that happened, I became a lot happier. And guess what? I hardly disappointed anyone.

The Importance of Saying No

When you learn the art of saying ‘no,’ you begin to look at the world differently. Rather than seeing all of the things you could or should be doing (and aren’t doing), you start to look at how to say yes to what’s important.

In other words, you aren’t just reacting to what life throws at you. You seek the opportunities that move you to where you want to be.

Successful people aren’t afraid to say no. Oprah Winfrey considered one of the most successful women in the world confessed that it was much later in life when she learned how to say no. Even after she had become internationally famous, she felt she had to say yes to virtually everything. It was only when she realized that after years of struggling with saying no, I finally got to this question: “What do I want?”

Being able to say no also helps you manage your time better.

Warren Buffett views no as essential to his success. He said,

“The difference between successful people and really successful people is that really successful people say no to almost everything.”

When I made ‘no’ a part of my toolbox, I drove more of my own success focusing on fewer things and doing them well.

How We Are Pressured to Say Yes

It’s no wonder a lot of us find it hard to say ‘no.’

From an early age, we are conditioned to say ‘yes.’ We said yes probably hundreds of time in order to graduate from high school and then get into college. We said yes to find work. We said yes get a promotion. We said yes to find love and then yes again to stay in a relationship. We said yes to find and keep friends.

We say yes because it feels better to help someone. We say yes because it can seem like the right thing to do. We say yes because we think that is key to success. And we say yes because the request might come from someone who is hard to resist like the boss.

And that’s not all. The pressure to say yes doesn’t just come from others. We put a lot of pressure on ourselves. At work, we say yes because we compare ourselves to others who seem to be doing more than we are. Outside of work, we say yes because we feel guilty we aren’t doing enough to spend time with family or friends.

The message no matter where we turn is nearly always, “You really could be doing more.” The result? When people ask us for our time, we are heavily conditioned to say yes.

How to Say No Without Feeling Guilty

Deciding to add the word ‘no’ to your toolbox is no small thing. Perhaps you already say ‘no’ but not as much as you would like. Maybe you have an instinct that if you were to learn the art of ‘no’ that you could finally create more time for things you care about. But let’s be honest, using the word ‘no’ doesn’t come easily for many people.

The 3 Rules of Thumbs for Saying No

1. You Need to Get Out of Your Comfort Zone

Let’s face it. It is hard to say no. Setting boundaries around your time especially you haven’t done it much in the past will feel awkward.

2. You Are the Air Traffic Controller of Your Time

Remember that you are the only one who understands the demands for your time. Think about it, who else knows about all of the demands on your time? No one. Only you are at the center of all of these requests. are the only one that understands what time you really have.

3. Saying ‘No’ Means Saying ‘Yes’ to Something That Matters

When we decide not to do something, it means we can say yes to something else. You have a unique opportunity to decide how you spend your precious time.

6 Ways to Start Saying No

Incorporating that little word ‘no’ into your life can be transformational. Turning some things down will mean you can open doors to what really matters. Here are some essential tips to learn the art of no:

1. Check in With Your Obligation Meter

One of the biggest challenges to saying ‘no’ is a feeling of obligation. Do you feel you have a responsibility to say yes and worry that saying no reflect poorly on you?

Ask yourself whether you truly have the duty to say yes. Check your assumptions or beliefs about whether you carry the responsibility to say yes. Turn it around and instead ask what duty you owe to yourself.

2. Resist the Fear of Missing out (FOMO)

Do you have a fear of missing out (FOMO)? FOMO can follow us around in so many ways. At work, we volunteer our time because we fear we won’t move ahead. In our personal lives, we agree to join the crowd because FOMO even while we ourselves aren’t enjoying the fun.

Check in with yourself. Are you saying yes because of FOMO or because you really want to say yes? More often than not, running after fear doesn’t make us feel better.

3. Check Your Assumptions About What It Means to Say ‘No’

Do you dread the reaction you will get if you say no? Often, we say ‘yes’ because we worry about how others will respond or the consequences of saying no or because of the consequences. We may be afraid to disappoint others or think we will lose respect from others. We often forget how much we are disappointing ourselves along the way.

Keep in mind that saying ‘no’ can be exactly what is needed to send the right message that you have limited time. In the tips below, you will see how to communicate your no in a gentle and loving way. You might disappoint someone initially but drawing a boundary can bring you the freedom you need so that you can give freely of yourself when you truly want to.

4. When the Request Comes In, Sit on It

Sometimes, when we are in the moment, we instinctively agree. The request might make sense at first. Or we typically have said yes to this request in the past.

Give yourself a little time to reflect on whether you really have the time, or can do the task properly. You may decide the best option is to say ‘no.’ There is no harm in giving yourself the time to decide.

5. Communicate Your ‘No’ with Transparency and Kindness

When you are ready to tell someone no, communicate your decision clearly. The message can be open and honest to ensure the recipient that your reasons have to do with your limited time.

Resist the temptation not to respond or communicate all. But do not feel obligated to provide a lengthy account about why you are saying no.

A clear communication with a short explanation is all that is needed. I have found it useful to tell people that I have many demands and need to be careful with how I allocate my time. I will sometimes say I really appreciate that they came to me and for them to check in again if the opportunity arises another time.

6. Consider How to Use a Modified ‘No’

If you are under pressure to say yes but want to say no, you may want to consider downgrading a “yes” to a “yes but…” giving you an opportunity to condition your agreement to what works best for you.

Sometimes, the condition can be to do the task but not in the time frame that was originally requested. Or perhaps you can do part of what has been asked.

Final Thoughts

Beginning right now, you can change how you respond to requests for your time. When the request comes in, take yourself off autopilot where you might normally say yes.

Use the request as a fresh request to draw a healthy boundary around your time. Pay particular attention to when you place certain demands on yourself. If you are the one placing the demand on yourself, try to evaluate the demand as if it were coming from somewhere else.

Try it now. Say no to a friend who continues to take advantage of your goodwill. Or, draw the line with a workaholic colleague and tell them you will complete the project but not by working all weekend. Or, tell someone in your family you can’t loan them money again because they never paid you back the last time. You’ll find yourself much happier.
