Workout Wednesday: Five Health Benefits Of Regular Exercise That You Can’t Get From Good Nutrition Alone

by Emily Wheeler

On Tuesday, I talked about the health benefits of good nutrition that you can’t reap just from exercising regularly and, as promised, today we’re exploring the opposite topic: what are some of the heath benefits of exercising regularly that we can’t get simply from having healthy dietary habits?

1.   It not only reduces, but reverses the effects of stress on our bodies, and can help to lessen depression! If there is something that all college students have in common, I would have to say that it would be stress.  Even in this big bundle of diversity that we call UNC, we all have the common factor of stress, because there is most likely something in each of our lives that keeps us on edge, whether that thing is grades, our parents, money, or just figuring out what we’re doing with our lives.  Over time, stress can cause some wear and tear to our bodies, which translates into faster aging of our tissues as well as mental side effects, such as depression, which can then translate into more stress because it makes it even harder to overcome the thing that causes us stress! However, the good news is that a study from the University of California—San Francisco in 2010 showed that exercise can actually create a visible difference in the physical aging of and damage to our individual cells.  Stressed out women exercising for as little as 45 minutes a day for 3 days (only three days people! That’s the time between now and the blog I posted on Tuesday!) had cells that “showed fewer signs of aging compared to women who were stressed and inactive.” It is also proven to lessen depression by releasing chemicals in the brain that work to make us happier and more satisfied with our lives from a scientific perspective. Wrinkle cream? Try exercise instead.

2.     Hello muscle mass! Everyone knows that if you want to bulk up and add some extra muscle mass to your already schmexy body, all you have to do is walk around eating protein bars and drinking protein shakes and your muscles will just automatically start growing, right?  If you just agreed with that statement I’m going to find you and personally kick the protein bar out of your hand.  You have been warned.  In reality, they key to gaining muscle mass and simply becoming stronger is exercise, because although food provides the energy, you have to put that energy to good use in a way that can actually stimulate change in your body composition! This is why a mixture of cardio and strength exercises in your weekly routine is especially swell, because let’s not forget that our hearts are muscles too! Want stronger legs? Squats and lunges can target those muscles. Arms? Try out some dumbbells or even some barbells! There are muscle cut group fitness classes this semester that use both! The main idea: to strengthen a muscle, you have to use it and make it work more than it would on just any old regular day.

3.     Anyone care for a little extra euphoria? Those chemicals that I mentioned earlier as beneficial for reducing depression include serotonin, dopamine, and norepinephrine.  That runner’s high that you hear people talking about (even though I have quite a hard time finding it myself) really does exist, because the same chemicals are released in response to exercise as to many drugs that people take for the feeling of that “high” euphoria. Try out different times of the day to get in just 30 minutes to an hour of exercise, and see if it doesn’t leave both your body and mind feeling better afterward! Two days per week, I get up and exercise in the morning before my first class, because those are my longest days of class and I know that starting off my day with exercise keeps me more alert and in a better mood than if I just roll out of bed and lumber directly off to class.

4.     Fight the loss of brain function with age and help prevent the possible onset of Alzheimer’s. Many studies have been done in the past few years concerning Alzheimer’s disease and brain function, including memory, with age.  Although nothing has been proven to guarantee prevention of Alzheimer’s or brain function with age, one thing that has been proven to delay these events drastically is exercise.  It seems that not only does exercising regularly keep your body fit, but it can also serve to improve and maintain cognitive function, much like muscle function!  If you don’t think that this affects you, consider this quote from an article entitled “7 Mind-Blowing Benefits of Exercise”: “In 2000, Dutch researchers found that inactive men who were genetically prone to Alzheimer’s were four times more likely to develop the disease than those who carried the trait but worked out regularly.” You have the power to drastically reduce your chance of developing a devastating disease just by taking action now to keep yourself healthy and to protect you brain– why wouldn’t you do it?

5.     Be happier with what you see in the mirror. This one is not only related to the fact that those happy chemicals are floating around in your brain after you finish exercising, but it also relies on the fact that exercising naturally makes us proud of ourselves, because we got out and did something and used our bodies for good that day.  Even if not a single physical thing changes about your appearance, the act of doing exercise makes us feel more active and happy about doing something to improve ourselves, no matter how much you weigh and what you look like.  Food can also make us happy and eating well can make you feel better about yourself, but it’s just not quite the same as looking in a mirror at yourself and the sweat you just poured into the last hour and feeling the satisfaction of hard work well done.

6.    Get more done. (Bonus!) Stuck in the middle of writing a paper? Too tired to even start writing the paper? Getting away from the computer and doing some exercise might be the answer! Exercising increases blood flow to the brain, which can help to take away that sleepy feeling and make you feel prepared to work. Personally, long reading assignments for class tend to make me sleepy, but I’ve found that if I read while pedaling on a stationary bike at the gym then I feel much more awake and more likely to remember what I read! People who make time to exercise for just 30 minutes a day tend to be more productive than those who do not, which means that next time you think you have too much homework to squeeze time for exercise into your schedule, do yourself and favor and go exercise anyway; you might just be surprised at what you accomplish.

    I don’t necessarily enjoy exercising. However, I am all about being healthy and having energy to do my best as a student.
    Hopefully these health benefits will motivate me to visit the gym on a regular basis!
