Laughing and singing more also can keep your lungs healthier. Keep your liver healthy by lying on your left side and gently hitting it quickly with your fist.
Start off by doing 20 strikes and gradually work up to as many as you can each day. Eat a proper, nutritious diet. Stay away from foods that contain pesticides, hormones and antibiotics. Also try to steer clear of fatty, oily foods. Your kidneys have to filter out all of these things. Try to eat more fruits, vegetables, whole grains, nuts, beans and soy. Stay away from drugs, alcohol and tobacco. Also try to use over-the-counter medications as sparingly as you can.
Never drink alcohol while you are taking medicine. On the downside, heart attacks can occur to anyone, even a world class athlete. It is worth noting, however, that far more Americans die each year of a sedentary lifestyle than they do from a fitness lifestyle.
When to eat and how much to eat are subjects of endless debate among experts. After all, in the short-term, when one exercises, the body must send more blood to the muscles; therefore, it must compensate by taking away from the needs of the stomach and the digestive system. This is why many experts believe eating a large meal too soon before exercise can cause stomach upset.
We have all heard the advice of our parents not to swim for a half-hour after eating because cramps could result, which to this day is a source of contentious debate. Furthermore, a really fascinating study of forty Irish Rugby players found that, versus another group of non-athletes, the rugby players had more gut microbiota in their intestines, which is beneficial in helping the body's immune system. The endocrine system is composed of a series of glands that secrete hormones.
Of special importance is the pituitary gland. In the short-term, exercise enables this gland to produce human growth hormone and secrete hormones that allow movement. Diabetes management comes into play here just as in the circulatory system. In the long-term, physical activity has a trifold effect of strengthening the ticker, lowering blood sugar levels, and improving insulin levels. It's not the most pleasant or glamorous system to discuss, but the excretory system is responsible for the critical role of removing liquid and solid wastes from the human body.
In the short-term, the rate at which the kidneys filter blood changes in relation to how hard the athlete exercises. Also, constipation may be relieved.
Of all the human body systems, the effect of physical activity on the immune system seems to spark the most debate among experts and scientists. It is now believed that physical activity helps to strengthen the immune system. The general theory is that exercise increases the cells, and even gut microbiota, in your body that help fight disease. When a person exercises, the effect of enhancing the immune system lasts for several hours. There is evidence, however, that exercising for over two hours may actually cause a short-term weakening of the immune system.
On the other hand, more intense physical activity for only about 30 minutes may not weaken the system. The evidence suggests that, if a person exercises for too long and doesn't rest enough, the immune system can suffer. The secret seems to be in finding a healthy balance between exercise and rest. More study will be needed to fully understand the connection between exercise and the immune system.

In the short-term, as the exercise level increases, the blood flow to the skin increases, and then the heat disappears through the pores. This has the positive effect of cooling the body. Also, sweat can be produced on the skin during this process. In the long-term, physical activity can keep the skin looking more youthful and feeling softer and more pliable.
In the short-term, exercise may cause muscle soreness and muscle fatigue. Exercise temporarily breaks down muscle, but crucial rest allows muscles to rebuild and grow. In the long-term, we see how physical activity may have a dramatic, positive effect on the muscular system. The muscles may become larger and stronger or, depending on the exercise, they may develop muscle endurance.
Exercises such as yoga may make the muscles more flexible. On the downside, the athlete may experience muscle pulls or even muscle tears. The nervous system is composed of the spine, the nerves, and the brain. Nascent research is finding exciting news that exercise can stimulate the entire nervous system.
If you have ever wondered why you felt better after a brisk walk or an aerobics class, there is a scientific explanation for this phenomena. Exercise actually boosts chemicals, known as endorphins , in the brain that help lift your mood. We have all heard someone joke about being on an 'endorphin high', and to many, this is more than just an expression. It should be duly noted, however, that there is another camp of scientists that say the runner's high is nothing more than a myth.
Many scientists now believe that exercise can do more than just elevate one's mood, it can also help alleviate depression in individuals who are prone to it. If that's not enough, physical activity may actually help stave off dementia.
Scientists haven't fully solved this riddle, but many theorize this is due to the increased blood flow to the brain, which somehow prevents plaque from building up in the brain, a symptom connected to dementia.
Exercise can have psychological benefits, as well. In the long-term, some people may become addicted to exercise in a similar way that people become addicted to drugs or alcohol or even food.
On the positive side, when one looks in the mirror and likes the results, exercise can result in improved self-image, self-confidence, and self-esteem. The average adult takes over 20, breaths each and every day. In the short-term, exercise increases the breathing which allows more oxygen to reach the lungs and the blood. In the long-term, exercise keeps the respiratory system and the lungs clear and healthy and able to produce more oxygen.
This means the lungs will operate at a more efficient level while having more lung capacity. In the long-term, exercise can help a person lose weight and maintain that weight loss. Much less stress is put on the ankles, knees, and other joints, lessening the chance of injury. In the long-term, however, exercise can also wear down the cartilage between the knees and cause pain and discomfort. Obviously the risk of injury to the skeletal system is always there for the athlete during exercise.
Sprains involve injury to ligaments and strains to tendons. There are also joint dislocations and, in the worst cases, fractures, breaks, or even death. Most experts now believe that physical exercise can play a major part in the overall health of the human body and in preventing premature death. In this lesson we discussed the effects of physical activity on the human body and its major systems. We discussed the circulatory, digestive, endocrine, excretory, immune, integumentary, muscular, nervous, respiratory, and skeletal systems.
Then, we looked at both the long-term and short-term effects of exercise on these systems. The information on this site is for your information only and is not a substitute for professional medical advice.

As the level of sodium in your bloodstream drops, ADH secretion also falls, and your kidneys produce urine that is more dilute. After a certain point, the hypothalamus begins to boost the release of ADH from the pituitary gland to conserve water as much as possible.
As ADH levels rise, the kidneys produce more concentrated urine, thus causing the level of sodium in the bloodstream to further drop. One of the ways your body excretes toxins is through sweat. When you exercise, you sweat more and you also need more water.
