Summer is hot and full of vitality. In summer, most people get sick immediately, so there is a saying that "the debt is quick in June". Middle-aged and elderly people have a high incidence of cardiovascular and cerebrovascular diseases, especially in summer, when the temperature rises, the metabolism of human body is obviously accelerated, the blood flow of skin is increased several times than usual, and the blood flowing back to the heart is reduced, which will directly affect the blood supply of myocardium. Therefore, the summer health care of this group can not be ignored, and it is very reasonable for Chinese medicine to advocate "Xia San in winter". According to China's health theory, the summer health care of middle-aged and elderly people focuses on nourishing yang and balancing. Here are some tips for spending the summer safely: It is very important to eat clearly rather than lightly. In summer, we should drink more boiled water, eat more vegetables, and insist on "clear", but we should also pay attention to the intake of milk, eggs and meat, so as to match meat and vegetables, sour and salty. In the choice of edible oil, we should also pay attention. Here, experts believe that corn oil is the first choice for light edible oil. It is rich in unsaturated fatty acids, vitamin E, phytosterol and other nutrients, and has rich nutritional value. Linoleic acid is an essential fatty acid for human body. Long-term consumption has a certain effect on softening blood vessels, assisting in lowering blood lipid, preventing and improving arteriosclerosis. If middle-aged and elderly people want to spend their summer healthily, a correct and reasonable diet is of course the key, but other aspects are equally indispensable: keeping relaxed and persistent; The environment is cold but not cold; The amount of exercise decreased and continued; Sleep is lacking, but not lacking. At present, it is summer in Xia Zhishi. Middle-aged and elderly friends should not only develop good habits of calmness in their daily life, but also pay attention to daily health, reasonably match their diet and guard against cardiovascular and cerebrovascular diseases.
