24. What happens to your body?
Exercising makes the body pump more blood to the muscles. This will increases blood flow, which is beneficial for your brain. Once you’re done with exercising your brain will release more endorphins, which will elevate your mood for the day. When you start moving, your body’s energy expenditure increases. That’s why we often feel so at ease and things are clear after exercising and eventually happy. At the same time, endorphins, another chemical to fight stress, are released in your brain. Essentially, when you start exercising, you feel better because your brain and body can do more.
You’re not winded walking upstairs. Your heart rate and blood pressure go down, which decreases your risk for a number of diseases and gives you more energy. When you exercise, heart rate increases to circulate more oxygen (via the blood) at a quicker pace. Eventually, this lowers resting heart rate in fit people. Exercise also stimulates the growth of new blood vessels, causing blood pressure to decrease in fit people. Exercise helps people lose weight and lower the risk of some diseases. Exercising regularly decreases a person’s risk of developing certain diseases, including obesity, type 2 diabetes, and high blood pressure. Exercise can help a person age well.
