We all know that exercise is good for our minds and bodies. We know that it makes us stronger, curbs our risk of developing many chronic diseases, and just helps us feel great. However, not all of us are aware of exactly how exercise changes and improves our bodies. Here are six things that happen to your body when you work out—some of them may surprise you!
Your Brain Floods With Endorphins
Ever heard of the runner’s high? That euphoric, stress-free feeling isn’t just in your head—well, actually, it kind of is. When you work out, your brain releases endorphins, chemicals that naturally boost your mood and help you feel amazing.
It’s probable that your brain releases endorphins to suppress exercise-related pain, but they also reduce anxiety and leave you feeling mentally refreshed. Exercise is truly a win-win for your body and mind.
Your Oxygen Intake Capacity Increases
The more you exercise, the better your body becomes at using and delivering oxygen to your muscles. This is because your lungs get stronger and more efficient, and your blood volume increases.
Increased oxygen capacity helps you exercise for longer and with greater ease, particularly when it comes to cardio. You’ll notice that climbing stairs and running to catch the bus feel less like struggles when you’re consistent with your workouts.
Your Immunity Gets Stronger
Regular exercise increases the circulation of your white blood cells, the little warriors in your body that fight off illnesses. Working out also temporarily raises your body temperature and helps your body get rid of lingering bacteria that could get you sick. By staying active, you’re giving your immune system the boost it needs to keep colds, flu, and other infections at bay.
Your Muscles Tear and Heal Themselves
During strength training or intense workouts, tiny tears occur in your muscle fibers. But don’t worry—it’s all part of the process. Your body repairs these tears while you rest, rebuilding the muscle stronger than before. During the recovery period, you may experience delayed onset muscle soreness (DOMS), which is just your body noticing the microtears. Products like muscle gels are popular to relieve this discomfort while your body heals to become stronger and more toned.
Your Sweat Glands Become More Efficient
Sweating is your body’s natural cooling system, and regular exercise fine-tunes it. When you work out consistently, your sweat glands adapt and improve their efficiency. This means you’ll start sweating sooner and in greater amounts. You might not love becoming sweatier, but it’s important to keep your body cool and go harder for longer without overheating.
Your Resting Heart Rate Lowers
Your heart is a muscle, and like all muscles, it gets stronger with exercise. A stronger heart pumps blood more efficiently, which means it doesn’t have to work as hard when you’re at rest. The result? Over time, your resting heart rate will likely lower.
Did any of these things that happen to your body when you work out surprise you? Even a little exercise, if you perform it consistently, can give your body a shot at experiencing all of these benefits. The next time you think about skipping your workout, remember what you stand to gain!
