In everyday life, many people, especially the elderly, experience cramps in their calves. Many people simply think that cramps are mainly related to calcium deficiency. However, even with active calcium supplementation, many people still get cramps at night. Because there are many causes of leg cramps, only the right treatment can have good results. Then the elderly leg cramps is how it is? How to protect the legs of the elderly? The elderly leg cramp is how? 1, cold stimulation cold is the most common direct cause of cramps, can directly stimulate the leg muscles caused by strong contraction and sudden spasm of the blood vessels. 2, excessive sweating long exercise, anaerobic exercise, sweating, the body of liquid and electrolyte loss of large amounts of such as low-calcium, low-potassium, low-magnesium, a large number of metabolic wastes accumulate, the internal environment disorders, but also prone to spasms. 3, the local compression, such as Long time lying on the back, so that the quilt pressed on the foot, or long time lying down, so that the foot against the bed, forcing some muscles of the calf for a long time in a state of compression, causing muscle “passive contracture” and insufficient blood supply. 4, hypocalcemia in the process of muscle contraction, calcium ions play an important role. Due to the weakening of calcium absorption ability of the elderly and the obvious loss of calcium, children and pregnant women in vivo calcium due to the body to consume too much calcium, when the concentration of calcium ions in the blood is too low, the muscles are prone to excitement and spasm. 5, weakness and fatigue over-exercise, especially anaerobic exercise leads to short-term continuous contraction of the muscles, the body produces a large number of metabolic wastes, the state of muscle tension at night has not been improved, the accumulation of too many acid metabolites, can stimulate the calf to “passive contracture” and insufficient blood supply. Failure to clean up in time, can stimulate calf cramps, the elderly frail muscle strength poor metabolic function of the body is also one of the reasons. 6, vascular factors are often the intrinsic cause of cramps, when the arteries undergo atherosclerosis, or the presence of thrombosis, the blood circulation is blocked poorly, the local tissues of ischemia and anoxia, physiological disorders, will cause lower limb cold, numbness and intermittent claudication, that is, when walking the calf muscle numbness, pain or even spasm. That is, when walking, the calf muscle numbness, pain or even spasm, disappear after resting, and then appear again when walking; in severe cases, there may be persistent pain, and the arteries of the lower limbs, especially the dorsalis pedis artery pulsation is weakened or disappeared. The metabolites can not be taken away in time, reach a certain concentration, will also stimulate muscle contraction, causing pain and cramps. How to protect the legs of the elderly? 1, rubbing the legs with both palms tightly clamped on one side of the calf belly, while turning the side of the rubbing, each side of the rubbing about 20 times. 2, more sunshine is not only conducive to warmth, but also promote the formation of vitamin D in vivo, to avoid the legs of the loss of calcium, and effective prevention of osteoporosis. 3, moderate leg arm lightly against the wall on one side of the leg on the opposite side of the crotch as the axis of the gently flinging, 5 times for the other leg to do the same! Action, morning, noon and night three times, you can let the blocked microcirculation to re-open up, but also to a certain extent to reduce blood viscosity. 4, rubbing legs massage cream evenly coated in the legs, rubbing the palms of the two hot, from the thighs of the thighs in the direction of the clockwise direction of the inner legs gently rubbed all parts of the legs, so that you can improve blood circulation, activate the cellular metabolism, muscle and collateral, the legs of the self-heat system in this regard was opened. 5, hot water soak feet. 5, hot water foot soak with hot water, especially with ginger or chili pepper decoction water foot wash, can be faster expansion of the human respiratory mucosa capillary network, accelerate blood circulation, so that the respiratory mucosa in the blood in the blood of the white blood cells in a timely manner to eliminate the invasion of the human body bacteria and viruses, so that the human body is free from infection. 6, twisting the knee to activate the blood vessels parallel to the feet together, bending the knees slightly downward squatting, hands on the knees, clockwise twisting The number of 10 times, and then counterclockwise twisting. This method can dredge the blood, prevention and treatment of lower limb weakness, knee pain and other diseases. However, note that the knee joint itself has lesions of patients should not do this movement. 7, dry cleaning legs with both hands embrace the side of the thigh, a little force from the thigh downward massage, has been to the ankle, and then from the ankle massage to the root of the thigh, with the same method of massaging the other leg, repeat 10 to 20 times. This can make the joints flexible, leg muscles and walking ability to enhance the prevention of varicose veins of the lower limbs, edema and muscle atrophy.
