How is sweating in summer? It often causes headaches.

Prevention and care of common headaches in summer In the hot summer, although we can put on beautiful summer clothes and go swimming at the seaside, headaches are lurking around us waiting for opportunities for action. Although there are many effective ways to relieve headaches in summer, there are many kinds of headaches in summer, such as colds, cold drinks, water poisoning and so on. Clinical investigation and modern medical research show that high temperature, stuffy humidity, thunderstorm, strong wind and sudden weather change often induce or aggravate headaches in summer. So, what headaches may we face in summer? How to prevent and care for a healthy and happy summer? This article will introduce them one by one. Common headaches may fall into the following four categories: 1. Headache in summer. This is a very typical seasonal headache. Some people will get sick in summer, and with the arrival of autumn, the weather will turn cold and they will recover. The summer climate is hot, especially in the early summer when the temperature difference between morning and evening is large and the hot summer when the temperature exceeds 37℃, some people will find it difficult to adapt, so the autonomic nerve function will be disordered, loss of appetite, insomnia and forgetfulness, general fatigue, and severe headache is often accompanied by low fever. Prevent headaches and eat more fruits and vegetables in summer. If you have a headache in late spring, you should take preventive measures in advance, clean up the living environment at home, keep the indoor furnishings as clean as possible, keep them ventilated and clean, and have no sultry feeling. In summer, we should improve our diet, eat more fruits and vegetables, pay attention to cooling down and ensure adequate sleep time. Go out and do a good job of sun protection. Once you have a headache in summer, you should transfer the patient to a cool environment in time, but the temperature should not be too low to prevent discomfort caused by excessive temperature difference, and you should eat light and refreshing food to replenish energy and have more rest. 2. Cold drinks and headaches. When summer comes, cold foods such as iced watermelons, iced drinks and ice cream naturally become people's favorite. However, cold drinks will bring strong stimulation to oral mucosa when entering the mouth, which may cause radiation pain to the nerves of palatal skin. These pains may not be obvious to ordinary people, but they are dangerous to some patients with a history of headache (such as migraine), because such stimulation may trigger an acute headache attack. After eating cold drinks, these patients often have symptoms such as closing their eyes, unbearable headache, and even tinnitus, dizziness and mild nausea. Although watermelon is good, you should eat it slowly. Therefore, if people with a history of headaches come in summer, don't be greedy and try to eat less or no cold drinks. Cold drinks are best eaten between meals to reduce irritation. At the same time, do not eat cold drinks immediately after sweating. You should dry your sweat first, drink some warm tea, and then have cold drinks. Once this kind of "ice cream headache" occurs, if it is not very serious, you can massage the part repeatedly by hand to relieve the pain, and you can also contain warm water in your mouth to slow down the stimulation to the upper jaw. If you have a particularly bad headache, you should seek medical advice in time. 3. Dehydrated headache. In summer, the temperature is often higher than the human body temperature, and the human body will sweat a lot in order to dissipate heat. When sweat evaporates too much and cannot be replenished in time, the human body will be easily dehydrated. In addition, because of the hot weather, food in summer is relatively easy to deteriorate. People who eat bad food and suffer from acute gastroenteritis or bacillary dysentery will vomit and diarrhea at the meeting, leading to dehydration. When the human body is dehydrated, the cerebrospinal fluid will decrease and the gap between the skull and brain tissue will increase. When the body position changes, especially when standing, the brain tissue will "sink" or "shake" slightly, so that the nerve roots and blood vessels of the brain are pulled, and headache symptoms appear, which is called dehydration headache. To prevent dehydration headache, first of all, drink more water than other seasons in summer, especially add salt in moderation, so some electrolyte drinks are more suitable for drinking in summer. At the same time, we should pay attention not to exercise excessively in the sun in summer, pay attention to personal hygiene and diet to prevent gastrointestinal diseases. However, if this kind of headache happens unfortunately, you should stay in bed immediately, but don't lower your head with a pillow. In order to eliminate and alleviate dehydration, a certain amount of physiological saline can be injected to eliminate or alleviate dehydration and relieve dehydration headache. 4. Water poisoning and headache. This kind of headache is just the opposite of dehydration headache. It's hot in summer and people sweat easily. Some people drink too much water after sweating, commonly known as "cow drink", so that the electrolyte mainly containing sodium in the body will be diluted rapidly, resulting in a decrease in blood osmotic pressure, and water will penetrate into cells through cell membranes, causing cell edema and "water poisoning", which is very harmful to the human body, especially brain cells. Once the brain cells are edematous, the intracranial pressure will rise, so a series of nerve stimulation symptoms will appear. Water can carry a boat, but it can also overturn it. Drinking milk carefully is harmful to your health. Therefore, in order to prevent toxic headache in water, it is not advisable to drink too much water too quickly or too slowly after sweating a lot, and it is advisable to drink it in moderation, not exceeding 300ml at a time. At the same time, it is necessary to supplement appropriate salt, and it is best to add appropriate salt to drinking water. After toxic headache in water occurs, salt should be replenished in time to adjust the balance of water and salt. In severe cases, normal saline with appropriate concentration should be injected to relieve pain. In addition to the common headaches mentioned above in summer, patients with hypoglycemia, cerebrovascular diseases, cervical spondylosis, intracranial space occupation, intracranial verification, and blood viscosity should pay special attention in summer vacation. In order to avoid the corresponding headaches caused by these diseases in the case of high temperature, sultry weather and thunderstorm weather. In summer, in addition to physical fitness, diseases and other reasons, irritability, diet fermentation, tension, anxiety and so on will also easily bring headaches. So in the scorching sun, for the sake of health, we should pay attention to the details of life. Only by scientific prevention can we resist headaches and spend a wonderful summer.
