Sun protection
Although it has entered autumn, the temperature has recently dropped across the country, but before and after the National Day "autumn tiger" will make a comeback, Hunan, Jiangxi and other places The temperature will rise to 30 + °C, for friends who want to go to outdoor activities or go to distant tourism (such as northwest, coastal and other areas with strong ultraviolet rays), we must be prepared for the following sunscreens:
Physical sun protection. Umbrellas, sun protective clothing, sunglasses, hats and other methods can isolate most of the ultraviolet rays and protect our skin. When you are not fully prepared for outdoor activities, ordinary clothing can also play a certain role in sun protection.
Sunscreen. Outdoor activities are best to prepare SPF 50, PA+++ sunscreen, the sun protection coefficient is too low to cause a good sun protection effect. In addition, the amount of sunscreen should be sufficient, such as the amount of a coin's size for the face. Especially pay attention to beauty lovers, please pay attention to the fact that as long as it is possible to expose the skin, you must also remember to reapply every 3-4 hours.

Many people think that the weather is cooler and mosquito bites are no longer a bother to go out. In fact, in the southern region, as long as the temperature is not particularly low, mosquitoes will always be active. Especially this year, many places in the Yangtze River Basin have a special number of mosquitoes due to dry weather. The doctor recommends that friends who are ready to go out should be prepared for mosquitoes and insects as much as possible, and do not let small mosquitoes spoil the good mood of the rare holiday.
Cryptoptera. Because it looks like ants, it is also called "flying ants". Features: long and narrow body, yellow and white skin, a pair of invisible wings (difficult to see with the naked eye). If the human skin is contaminated with its toxins, erythematous edema or small pustules can be seen, and at the same time feel burning, pain, itching, etc., which we call cryptoptera dermatitis, and the face of cryptoptera needs to remember to "stay away from it and not shoot".
Ticks. As a vector of multiple diseases, its appearance is characterized by 8 legs, a black-brown insect body, and the size of a whole watermelon seed. Tick bites, light inflammation, ulcers, heavy multiple organ failure, death. Therefore, outdoor activities should wear long-sleeved trousers, if accidentally bitten, should keep in mind that "can not shoot, can not be pulled, timely medical treatment is the most correct".
Prevent accidental injuries
If you are accidentally scratched by a knife or accidentally fall while playing, you can handle the wound if there is less superficial bleeding from the wound. For example, timely removal of mixed pollutants on the surface of the skin, rinsing the wound with pure water or tap water, and if possible, you can rinse with normal saline or complex iodine, and then use clean gauze to stop the bleeding. Deputy Chief Physician Liu Chaosheng especially reminded that if there are cases of being injured by rusty knife tools, foreign bodies are difficult to clean, wounds are red, swollen and purulent, etc., they should seek medical treatment in time to avoid wound infection, especially to avoid infection with tetanus.
