(1) The pressure on the abdomen when squatting is greater than that when sitting, which can reduce the stress on the abdomen and help to defecate smoothly.
(2) Squat exercise can enhance the stability of knee joint and the muscle strength of lower limbs, thus promoting the improvement of speed, explosiveness and endurance.
(3) It is easier to empty the colon when squatting in the toilet, so that pathogenic bacterial toxins in the intestine are not easy to accumulate. Moreover, when squatting in the toilet, you don't directly touch the toilet, which can reduce the probability of infection and be safer and healthier.
2. Disadvantages:
(1) The mobility of hip and knee joint in the elderly is limited. When squatting, the center of gravity is lowered, which will make the knee joint bear too much weight. Violent standing can also stimulate the blood pressure of the elderly, leading to blood pressure instability.
(2) Squatting posture is helpful for defecation in theory, but it may not be advantageous for some elderly people, especially those with cardiovascular and cerebrovascular diseases. Because the abdominal pressure increases when squatting, coupled with the exertion of defecation, cardiovascular accidents are prone to occur.
