The effects of exercise on cholesterol and body fat are on the positive side. According to the source doctors aren’t entirely sure how exercise can reduce cholesterol. One way that exercising helps to lower cholesterol and body fat levels is by helping you lose/maintain weight, because being to overweight increases the number of low-density lipoprotein lipids in your bloodstream. These lipoproteins have been linked to heart disease. One mechanism that researchers believe to be true is that exercise stimulates enzymes that push the lipoprotein lipids from the blood/blood vessel walls to the liver where it is then processed into bile for digestion or excretion. The more exercise you do, the more lipoprotein lipids your body expels.

While you exercise your body’s need for blood and oxygen begins to increase. To meet those demands the heart must then pump faster and harder. Because the heart begins to work harder, your pulse rate naturally rises and your heart pumps blood faster through your arteries. Because the heart is pumping blood through your arteries faster, the pressure inside also increases, which then causes an increase in blood pressure. Now what about the long-term effects? Regular physical activity will make the heart stronger and more efficient. The more efficient that heart becomes the easier it will be to pump greater amount of blood. Because the heart doesn’t have to beat as fast to move blood through the body, less stress and pressure is put on the arteries.

Exercise along with the proper nutrition and medication helps to keep Type 2 diabetes under control. What exercise does is lower the blood sugar levels and aids insulin to work more effectively. Exercise also helps prevent diabetes by burning excess body fat, and helping to decrease and control weight.

Physical activity isn’t just good for your physical body it’s also good for the psychological part of your body or you mental well-being. According to the source, experts believe that exercises releases chemicals to your brain that make you feel good. Exercise done regularly can also increase your self-esteem and even help you concentrate, sleep, look better, and feel better. Besides releasing chemicals to your brain that make you feel good there are other psychological benefits to exercise. Taking part in physical activities gives the opportunity to meet new people who share the same interest in exercise as you, make new friends, and just get away from the hustle and bustle of daily life and just give yourself some quiet time. The same effects carry over to mental disorders. Over 25 percent of the U.S. population is suffering from a mental disorder, and one of the best tools for treatment is exercise. Exercise helps you take your mind off of everyday worries and let you settle down for a while. Constant worrying about stressors can lead to anxiety and soon after, depression. Exercise has been a proven coping method to prevent depression. There are certain neurotransmitters in the brain that, in a depressed person, become decreased; those neurotransmitters are serotonin, dopamine, norepinephrine. The levels of these neurotransmitters have a direct effect on a person’s mood and become lower in level when a person has low self-esteem.
