What are the benefits of 2 hours of aerobic exercise?

There are many aerobic exercise programs, and different sports have different effects on the body, but in general, they can effectively help the body improve immunity and enhance cancer prevention and anti-cancer capabilities. Two hours of aerobic exercise every day will have many benefits for human health. Let us learn about some of the main benefits of aerobic exercise for people.

1. Aerobic exercise improves immune function and helps prevent cancer

Human cells themselves contain proto-oncogenes. When the human immune function is low, the proto-oncogenes will be stimulated by carcinogenic factors to mutate into cancer cells, and develop into cancer through continuous division and proliferation. This means that cancer cells can only grow and multiply when they escape the body's immune surveillance; if the body's defense mechanisms are intact, no cancer will occur. Therefore, improving the body's own immune function is the primary task of cancer prevention. Aerobic exercise is a long-term, low-to-moderate-intensity oxygen-consuming metabolic exercise that involves more than 2/3 of the body's muscle groups.

Many studies have confirmed that regular aerobic exercise can effectively improve your immune function. For example, it can significantly increase the body's immune cells such as T lymphocytes, B lymphocytes, and macrophages, thereby enhancing the body's ability to prevent and fight cancer. Professor Kono of Tsukuba University in Japan found through observation and research that female college students who exercised for more than 2 hours a day had significantly higher monocyte phagocytic function and T cell function than the control group (a group of women who did not like to exercise), proving that exercise is of great benefit to improving the body's defense and comprehensive immune function. Regular exercise can also increase the level of interferon in the blood. Interferon is an immune enhancer of the human body and has anti-cancer effects.

2. Aerobic exercise increases the activity of antioxidant enzymes, effectively removes free radicals and helps prevent cancer

The human body absorbs about 600 grams of oxygen every day. Oxygen is a "double-edged sword". While maintaining human survival, it also produces billions of "small cannonballs" - free radicals. Human cells are bombarded by thousands of "small cannonballs" every moment. Excessive accumulation of "little bombs" (free radicals) in the body can damage cell membranes, proteins, and nucleic acids, thereby inducing more than 200 diseases. It can also cause cell mutations and then develop into cancer.

However, the human body also has a system to remove these free radicals. The function of removing these free radicals is called "antioxidation". For example, superoxide dismutase (SOD) and glutathione peroxidase in the human body are antioxidant enzymes that can effectively remove free radicals. The higher the activity of antioxidant enzymes in the human body, the stronger its function of scavenging free radicals, which can prevent the occurrence of various diseases and even cancer. Many experimental studies have shown that persistent aerobic exercise can effectively increase the activity of antioxidant enzymes, thereby continuously eliminating excessive free radicals in the body and avoiding or reducing the occurrence of cancer.

Aerobic exercise can also help the body consume excess energy, especially for some friends who often like to eat high-fat and high-sugar foods. Long-term poor diet will cause a large amount of junk food and foreign fats to remain in the body, which can easily induce cardiovascular and cerebrovascular diseases and obesity. Proper aerobic exercise can reduce the probability of cardiovascular and cerebrovascular diseases.
