You already know that exercise is good for your body. But did you know that it can also improve your mood, improve your sleep and help you cope with depression, anxiety, stress, and other problems?

and there are many other surprising benefits of doing exercise.

 1. Physical activity is good for the brain.

 It is associated with lower depression, better memory, and faster learning ability. Research also shows that exercise is the best way to prevent or delay the onset of Alzheimer's disease, which is a major concern for many people,s today. Scientists do not know why exercise changes the structure and function of the brain. But it is a research area. To date, they have found that due to the BDNF protein (a neurotrophic factor), exercise can stimulate blood flow to the brain and promote the growth of new blood vessels and even new brain cells. BDNF stimulates the growth of new nerves and helps repair and protect brain cells from damage. According to recent research, it can also help people focus.

2. You can have more happiness.

 A large number of studies have shown that, from walking to biking, various forms of exercise can help people become better and even relieve symptoms of depression. Exercise triggers the elimination of neurotransmitters (serotonin, norepinephrine, endorphins, dopamine) in the brain, which can reduce pain, lower mood, and reduce stress. "For many years, we only focused on the physical benefits and ignored the mental and exercise benefits

 3. Age can be moved.

 Exercise can extend shelf-life up to 5 years. There are several new studies showing that excessive exercise can reduce cellular aging. As we age and cells divide regularly, telomeres, helmets, and chromosomes become shorter. To understand how exercise affects telomeres, the researchers biopsied and collected blood samples from 10 healthy people before and after a 40-minute cycle. They found that exercise increased the number of molecules that protect telomeres, 

ultimately slowing how quickly they shorten over time. Exercise, then, appears to slow aging at the cellular level.

 4. It will make your skin look better.

 Aerobic exercise accelerates blood flow to the skin, delivers oxygen and nutrients, improves skin health, and even helps wounds heal faster. This is why when people are injured, they need to move as quickly as possible, not only to ensure that the muscles do not shrink but also to ensure that the skin has good blood flow. The skin also serves as a heat release point. During exercise, muscles will generate a lot of heat, which must be handed over to the environment to avoid hyperthermia. The heat from the muscles is transferred to the blood, and the blood transports the heat to the skin; then it can escape to the atmosphere.
