Winter swimming is good for physical and mental health, and it is also good for the internal organs of the body. It's also good for the heart. It can promote heart function, improve cardiopulmonary function, enhance the contractility of cardiovascular and heart, strengthen cardiovascular system and exercise a strong heart for a long time.
What are the benefits of winter swimming for the heart to promote blood circulation? When a person is in the water, the gravity of the human body is mostly offset by the buoyancy of the water, so that the swimmer can move in a horizontal posture. In addition, the pressure of water on the skin makes it easy for blood from great veins to flow back to the atrium, creating good conditions for blood circulation in the body.
In winter swimming to improve heart function, the role of water makes it easy for limb blood to flow back to the heart, thus speeding up the heart rate. After long-term persistence, the blood volume of each contraction is greatly increased, the contraction is strong, the thickness of blood vessel wall is increased, the elasticity is increased, and the heart function is improved and improved.
Enhance vascular elasticity When swimming in winter, the water temperature will be lower than the land temperature. Due to the stimulation of cold water, the blood circulation and metabolism of the whole body will be enhanced, the skin blood vessels will contract sharply, and a large amount of blood will be sucked into the viscera, which will expand the visceral blood vessels. In order to resist the cold, skin blood vessels will expand rapidly, and a large amount of blood will flow back to the body surface from the internal organs, and the blood vessels will be exercised one by one, which can effectively enhance the elasticity of blood vessels and help prevent diseases such as high cholesterol, hypertension, arteriosclerosis and coronary heart disease.
Inhibition of winter swimming of atherosclerotic plaque can not only enhance the elasticity and adaptability of blood vessels, accelerate blood circulation, but also wash away fat particles and cholesterol deposited on the blood vessel wall, and prevent and delay the occurrence and development of atherosclerosis. Studies have shown that high density lipoprotein (HDL) in the blood of winter swimmers increases to varying degrees, while low density lipoprotein (LDL) decreases, thus inhibiting the formation of atherosclerotic plaques.
Can heart patients swim in winter? Winter swimming can enhance cardiovascular function and improve heart vitality, which has a certain effect on the prevention and treatment of heart disease, but whether heart patients can swim in winter depends on their condition. Patients with heart disease had better consult a doctor before going swimming in winter.
Patients with heart disease, such as congenital heart disease, coronary heart disease (untreated), viral myocarditis, hypertrophic cardiomyopathy, etc. Swimming is generally not allowed in winter. Once they swim vigorously, the oxygen and blood supply to the heart is insufficient, and coronary artery ischemia and vasospasm may occur, thus inducing arrhythmia, leading to myocardial infarction and sudden death. In addition, cold water stimulation can also cause coronary artery spasm and induce myocardial infarction.
4 precautions 1. If you have heart discomfort during winter swimming, such as chest tightness, angina pectoris, cold sweat, dizziness, arrhythmia, etc., you should stop swimming first and rest ashore. If you have a history of heart disease, take the quick-acting jiuxin pills you carry with you quickly, and it will be relieved in one minute. At the same time, you can feel your pulse yourself. If your heart beats too fast, you'd better see a doctor at once.
2. It is suggested to start swimming continuously in summer or autumn, and there should be a gradual process to avoid harm to the body.
Be sure to get ready for winter swimming and stretch all parts of your body and muscles. Don't jump into the water at once. I suggest you stand in the water to wash your feet and shampoo, splash water on your body and finally get into the water.
It is suggested that people with heart disease should not take risks in winter swimming to avoid unpredictable accidents.
5. After the winter swimming, you should immediately dry your body, put on warm clothes, do some stretching, brisk walking and other finishing activities, and don't immediately enter the hot room or take a hot bath.
