The summer weather is hot and dry, people sweat a lot and are tired of exercise, resistance decreases, so the hot cold becomes the most common disease in summer. The main cause of summer colds is often the inappropriate behavior of relieving the heat in order to cool off for a while, but ignore your own health. The main causes of summer colds Trigger one: improper diet Colds and diet are closely related, consuming too much food high in sugar and fat will speed up the consumption of water and vitamins in the body, reduce the efficiency of the body’s detoxification, leading to low immunity and causing hot colds. The diet in summer should be reasonable and light. Eating more melons, cool vegetables and antiseptic vegetables can not only clear heat and detoxify the body, but also get rid of dampness. Of course, the most critical thing is to replenish more water, strengthen the body metabolism and improve immunity. Causes two: often stay in air-conditioned rooms Staying in air-conditioned rooms for a long time, the skin pores are closed for a long time, can not sweat to dissipate heat, coupled with the inability to adapt to the temperature difference between indoor and outdoor, it is easy to suffer from heat colds. In order to reduce the temperature difference between indoor and outdoor, the temperature in the air-conditioned room is best between 24℃-27℃. For those who stay in the air conditioning room for a long time, try to use air conditioning less after arriving home. Trigger three: taking a cold shower Washing and bathing with cold water is not conducive to heat dissipation. At the same time, in a colder environment, the activities of muscles and internal organs are intensified, which greatly depletes one’s physical strength and leads to a decrease in immunity, so it is best to use warm water that you feel comfortable with when taking a bath. Once you have a hot cold, you should pay more attention to rest, minimize the discharge of sweat, take vitamin-rich fruits, eat liquid food, and take some medication to reduce the symptoms of the cold. What is the best thing to eat to prevent a “hot cold” in summer? Garlic The antibacterial effect of garlic is well known, especially the allicin contained in garlic has a strong anti-inflammatory effect, which can inhibit and kill various bacteria and viruses at the same time. And garlic is one of the easiest ways to prevent colds, just put a few slices of garlic in your usual stir-fry. Note: Although garlic is effective in preventing colds, it should not be consumed in excess, and it is best to limit the amount of garlic consumed to three or four cloves per day. If consumed in excess, it is likely to cause fire and stimulate the intestines. Lean meat Lean meat is rich in high-quality protein and nutrients such as magnesium and zinc, all of which have the effect of improving the immunity of the body. In addition to lean meat, foods like fish and shellfish also contain these nutrients. Zinc, in particular, activates the body’s white blood cells that fight viral infections and enhances cellular activity. Strawberries, citrus, broccoli These fruits are generally rich in vitamin C, which has antioxidant properties and boosts the body’s immune system. Therefore, for those who already have a cold, eating foods containing vitamin C can reduce the symptoms of the cold and shorten the duration of the illness. Broccoli contains a compound that is effective in reducing the incidence of respiratory infections and colds. Green tea Green tea is rich in antioxidants, which help to improve the immune function of our body to fight against various viruses and bacteria.
