Many people often have colds and drowsiness in early summer, so they should pay attention to this aspect of the regulation in early summer health care to prevent diseases. 1, diligent hand washing. Use soap or hand sanitizer and wash hands with flowing water, do not use dirty towels to wipe hands, hands should be washed immediately after contact with respiratory secretions. 2, sneezing or coughing when the application of handkerchiefs or paper towels to cover the mouth and nose, to avoid droplet pollution of others. Influenza patients should wear masks at home or when they go out to avoid infecting others. 3.Balanced diet, appropriate exercise, adequate rest, avoid excessive fatigue. 4. Open windows several times a day to keep indoor air fresh. 5. During the influenza season, try not to go to crowded places where the air is dirty; if you have to go there as a last resort, it is better to wear a mask. 6, in the flu epidemic season before the flu vaccination can also reduce the chance of infection or reduce flu symptoms. Studies have shown that often in a high-temperature environment, heat stress protein synthesis increases, so that the body’s heat tolerance; later re-entered the high-temperature environment, the degree of damage to human cells will be significantly reduced. Further research also reveals that the best way to gain or improve heat tolerance is to perform heat-resistant exercise, i.e., exercise in progressively higher temperatures to achieve the purpose of adapting to higher temperature environments. Early summer is the best time for heat-tolerant exercise because the change in the average daily temperature in early summer is consistent with a “gradual increase” in temperature. Early summer for heat-resistant exercise specific method Every day to set aside an hour or so for outdoor activities, according to the weather conditions, choose the temperature at about 25 ℃, humidity below 70% of the environment, walking, running, gymnastics, boxing and other exercise programs, each exercise should be to achieve the degree of sweating, in order to improve the body’s heat dissipation function. But not too much, especially when the temperature is higher than 28 ℃, humidity higher than 80%, to reduce the amount of exercise to prevent heat stroke. At the same time, in this period of time, as far as possible, do not use electric fans, air conditioning (rain or humidity, the use of air conditioning dehumidification), so that the indoor temperature is often maintained at 22 ℃ or above, the humidity is maintained at about 60%. After more than a month of heat-resistant exercise in early summer, the onset of summer, even if the indoor temperature of 28-31 ℃, outdoor temperature of 36-39 ℃ or more, the human body will not feel too hot.
