Introduction and preventive measures of high incidence diseases in summer

 As the temperature continues to rise in summer, the functions of various systems of the human body will change, which is prone to various diseases. How to prevent these in this sickly season in summer?


1、 Febrile cold

The so-called hot cold is that in summer, the blood vessels and sweat gland pores of the human epidermis expand and the amount of sweat increases in order to distribute the heat in the body. After falling asleep, the temperature decreases due to air conditioning and fans, and the body will catch cold again.

Those with mild febrile colds generally have no high fever and systemic symptoms, or only low fever, headache, systemic discomfort and other symptoms; Those with serious illness often have high fever, and the high fever does not subside after sweating, accompanied by headache, feeling top heavy, body laziness, fatigue, dry mouth but do not want to drink water, yellow and red urine, yellow and greasy tongue coating, and some patients will also have symptoms such as vomiting or diarrhea.

Febrile cold (air-conditioning disease) is a sub-health state. Its symptoms are mainly dizziness, fever, night sweat, and body weakness. Many people mistake it for a cold.

Air conditioning diseases mostly happen to people who have been indoors for a long time or office workers. Because indoor oxygen is constantly consumed and cannot be replenished in time, indoor air circulation is extremely poor. People will feel lack of oxygen after a long time in such an environment. When sleeping, people's metabolism slows down and they are more likely to be attacked by germs.

Warm warning: to prevent air-conditioning diseases, first of all, the temperature should not be set too low. It is best to have a temperature difference of 5 ℃ to 6 ℃ with the outside. Don't sweat profusely and blow the air-conditioning directly after entering the house from outside. This will make the sweat of the human body dissipate quickly, and will cause colds, rheumatism and other diseases. The desk must not be arranged in the place where the air is blowing directly. If you sit for a long time, such as typing, writing, etc., you should add clothes appropriately. At the same time, pay attention to standing up intermittently to promote peripheral blood circulation.


2、 Gastrointestinal diseases

Summer is the season of eating ice. With the continuous high temperature in Changsha for more than 20 days, the wind of eating ice is more prevalent. Ice watermelon, ice bean paste and ice beer have all become summer food. However, more and more patients with gastrointestinal diseases follow. Since the beginning of summer, the number of patients with gastrointestinal diseases received by the Department of spleen and stomach has increased by 20 to 30%.

Many citizens like to drink cold drinks in summer, but the temperature of the human body is generally high in summer. Eating a large amount of cold drinks will suddenly reduce the temperature of the human gastrointestinal tract, and the capillaries will contract suddenly, which is easy to induce gastroenteritis. Moreover, in hot and humid summer, various pathogenic microorganisms are easy to breed. In addition, people like to eat raw and cold food, which is more likely to cause acute gastritis, acute gastroenteritis, bacterial dysentery and other gastrointestinal diseases.

Another important reason is "spicy". Eating spicy food properly can remove moisture in the human body and increase appetite, which is beneficial to the body. However, excessive spicy food will cause strong stimulation to the stomach and intestines, which will damage the gastrointestinal mucosa and be prone to gastrointestinal diseases. The temperature in summer is high, the temperature of gastrointestinal tract is high, and the digestive capacity of human body is weakened. Excessive consumption of pepper or consumption of pepper before going to bed will cause a burden on the digestive system and be prone to gastroenteritis, gastric ulcer and other gastrointestinal diseases.

Warm warning: pay attention to food hygiene in summer, don't eat raw and cold or half raw meat food, and reheat or cook overnight food before eating; Avoid overeating, excessive spicy, diet should be light; Eat cold drinks moderately, and try to choose fresh food when choosing food.

3、 Cardiovascular and cerebrovascular diseases

In summer, especially when the temperature is high, the incidence rate of cardiovascular and cerebrovascular diseases is relatively high. When the temperature exceeds 34 ℃, the metabolism of human body will be significantly accelerated, and the blood circulation will also be significantly accelerated. Due to the high temperature, the skin blood flow increases 3 to 5 times than usual, and the blood flow back to the heart also increases significantly, which is bound to increase the burden on the heart. Coupled with a large number of sweating, the blood viscosity increases. When it reaches a certain degree, there may be a tendency of hemagglutination, leading to ischemia or blockage of cardiovascular and cerebrovascular vessels, which is prone to intra-arterial thrombosis, resulting in the occurrence of acute cardiovascular and cerebrovascular diseases.

In addition, under the muggy and hot weather, the patient's mood is depressed for a long time, easy to be nervous and irritable, and the spirit is in a state of stress for a long time, which promotes the secretion of some hormones in the body to increase, resulting in the increase of blood pressure and the rupture of blood vessels. High temperature weather, insufficient sleep time and excessive fatigue will lead to increased blood pressure and faster pulse. These adverse stimuli can directly induce and aggravate cardiovascular and cerebrovascular diseases, and even arrhythmia, which can cause sudden death in serious cases.

Warm warning: Patients with chronic cardiovascular and cerebrovascular diseases must adhere to taking medicine on time, maintain a peaceful mood, and strengthen the control of blood pressure. Reduce outdoor activities as much as possible in hot days, and try to choose a lower temperature period when going out, and avoid strenuous exercise outdoors. Ensure adequate sleep, which is conducive to good health and promote disease recovery. In addition, avoid overheating or cooling your body in summer, drink less cold drinks and more boiled water.
