Exercise gives you more energy. It seems counterintuitive to say that spending energy through exercise ends up giving us more energy, but this is true. In the long run, exercising strengthens our muscles and cardiovascular systems which mean that we don’t have to exert as much effort as we used to in doing normal things. Think of it this way: you may find it hard the first time you run 2 kilometers, but after doing it consecutively 10 times, it might not seem as hard as the first time. Having built up this stamina, you may find yourself not exerting too much of an effort carrying the kids around, doing the grocery or walking from work to lunch.
Exercise improves your overall mood. It has been proven that exercise actually helps people with depression stabilize their mood. Normal people can benefit from exercise too, in terms of helping them blow off steam after a particularly stressful day. Exercise lifts people’s moods because it releases chemicals in the brain which triggers happy emotions, particularly endorphins. Have you ever heard of the term “runner’s high”? This is a sense of euphoria that a runner experiences after he pushes himself past his perceived limits.
Exercise keeps us from getting sick. People who regularly exercise have stronger immune systems which mean that they are able to fight illnesses and infections better than people who are inactive. These illnesses can be the common colds, flu, cough or something more serious like chronic conditions hypertension, diabetes and cardiovascular diseases. Even if a person already has these chronic conditions, they can still benefit from exercise because exercising helps prevent complications that can arise from their conditions. For instance in the case of diabetes, exercise can help regulate blood sugars better, leading to a decreased risk of suffering from nerve damage.
Exercise can help people sleep better. People who have trouble sleeping or have irregular sleep patterns can benefit from exercising. Studies have shown that people who exercise sleep easier and more deeply that those who are inactive. However, you shouldn’t exercise too close to bedtime as this can actually cause you to stay awake because of residual energy.
Exercise can improve sex lives. Studies have shown that women who regularly exercise have an easier time getting sexually aroused, and men who exercise regularly also have fewer problems with erection—even as they get older.
