Exercise and immune system

Author(s): Sreenath S

The human body is surrounded by pathogens that like to invade the human body and cause diseases. Pathogens are micro organisms that has the ability to cause diseases. But our body has got a self defense mechanism called the immune system to attack against these pathogens. While a strong immune system protects your body from disease, your risk for illness elevates significantly when your immune system is compromised by stress or other factors. Regular exercise throughout the week strengthens your immune system and gives you a better chance to avoid the cold or flu as well as other serious health conditions like obesity, cancer, diabetes etc.
The immune system acts as a first line defender against harmful chemicals, bacteria or viruses that weaken your body and make you more susceptible to sickness. Your immune system also works around the clock to hinder the development of life-threatening disease like cancer. Although your immune system functions effectively on its own when healthy, making changes to your lifestyle can enhance a weakened immune system and empower your body. Doctors typically recommend adding fruits, leafy green vegetables and fiber to your diet, but regular exercise is also essential
Proper nutrition helps you avoid illness, although the Cleveland Clinic reports that exercise is more important to the health of your immune system than the foods you consume. Jogging, swimming and walking or aerobic activities are commonly regarded as the most beneficial type of exercise for your immune system, regardless of your age. Aerobic workouts, which require continuous movement of your arms and legs, make you breathe deeper and faster. While aerobic exercise often receives media attention as a way to protect your heart, the activity also strengthens your immune system and significantly decreases your likelihood for viral illnesses like the flu. People who perform regular aerobic exercise also enjoy a reduced risk of diabetes, cancer, stroke and cardiovascular disease. They also typically live longer than people who don't exercise.
While aerobic exercise like soccer or bicycling lowers your risk for illness, the physical activity also decreases your stress an enemy of a healthy immune system. Aerobic workouts help reduce stress, anger and depression by allowing your body to release healthy chemicals called endorphins that aid relaxation. Some doctors characterize endorphins as natural painkillers. Reducing stress benefits more than your immune system, as people with altered mood states are also more likely to suffer fatigue and sleeping problems.
Consider doing at least 20 to 30 minutes of aerobic exercise like brisk walking up to five days a week as an effective method to protect the health of your immune system. . Higher levels of aerobic activity typically provide a better chance for significant weight loss and increased energy. Start your aerobic regimen slowly and add to the pace only when your body feels ready. Moderate exercises is really good for your immune system and also to other parts of the body. The goal is to aim for 30 to 40 minutes of the above type of activities, at least five days a week for a better tomorrow
