Many data show that heart attacks increase a lot more than usual in winter. Experts say that in addition to keeping warm and preventing strenuous exercise in winter, prevention also requires attention to the following 10 areas: Sun exposure: Any area with a high rate of sun exposure has a small percentage of heart disease. Sunlight is beneficial to the body’s metabolism and can lower the cholesterol level in the blood. With low winter temperatures, around noon is a great time for sunbathing and should not be missed. Drink hard water: drinking hard water with high magnesium content can reduce the incidence of heart disease, magnesium ion is the body of a variety of enzymes, insufficient body content will lead to protein metabolism disorders, causing vascular sclerosis and heart damage, usually heart patients with magnesium ion content is 40% lower than healthy people. Eat fish: German experts found that the average daily consumption of 30-50 grams of sea fish, can make people suffer from heart disease risk reduced by half, because fish contains a large number of unsaturated fatty acids. Eat nuts: Swedish researchers surveyed 31,000 people showed that people who eat nuts at least once a day than those who do not eat the risk of heart disease by 53%, which contains unsaturated fatty acids in pecans, peanuts have a beneficial effect on the heart. Prevention of obesity: dieting, limiting fat intake and more exercise to maintain a relatively stable weight, can reduce the incidence of heart disease, especially men should especially prevent the emergence of chest and abdomen obesity date type body. Treatment of dental disease: people with periodontal disease have a 25% higher risk of heart disease than healthy people, which is related to the release of toxins from bacteria hidden in the periodontium to invade the blood circulation and poison the heart tissue. Therefore, maintaining oral hygiene and actively preventing dental disease can be effective in protecting the heart. Prevention of colds: Not all of the body’s immune responses stimulated by infectious diseases such as colds are beneficial. The increase in the number of white blood cells and the increase in immunologically active substances such as antibodies, in addition to resisting bacterial or viral attacks, can also be deposited in the walls of blood vessels leading to vascular sclerosis and inducing or aggravating heart damage. Less iron: High levels of iron in the blood are the second heart risk factor after tobacco. For every 1% increase in ferritin concentration, the risk of heart disease rises by 4%, and when the concentration of ferritin in the blood exceeds 200mg%, the risk increases twofold. Excess iron contributes to hardening of arteries and obstructs blood flow, and aggravates the condition of patients who already have heart disease.
