Summer is coming quietly, and the temperature outside makes us unable to go out, but we often choose to go out in summer vacation. The most important thing to play in summer is to prevent heatstroke~
How to prevent heatstroke in outdoor travel
1, drink water
Outdoor sports perspire much, must supplement moisture in time. The easiest and most effective way to prevent heatstroke is to drink water. Drinking water can not only quench thirst, but also heat and cool down. Therefore, Xiaobian suggests that you should take warm boiled water with you when you go out to play, and you'd better add a little salt. Don't wait to drink water when you are thirsty for a few times. Drink water slowly. Drink water more often than not. Don't drink a lot of water at a time. Because after exercise, drinking a lot of water will bring burden to blood circulation system, digestive system and heart, making people more tired. Serious still can cause convulsion, cramp.
2. Wear light colored clothes
Light colored clothes are characterized by slow heat absorption and fast heat dissipation. The best choice for outdoor travel is white, light or plain clothes, not black or purple and other dark clothes. It is also recommended to choose loose and comfortable clothes, which are easier to ventilate and dissipate heat than tights.
3. Take sun protection measures
Outdoor travel is the most afraid of the strong sunlight, UV UVA in the sun is the main cause of skin darkening. UVA is a long wave ultraviolet, which can directly absorb human skin and penetrate the dermis to make the skin tan, causing skin photoaging. Serious still can sunburn skin, let skin red swollen, desquamate. Therefore, it's best to apply sunscreen two hours in advance for outdoor travel, and wear sunshade hat, umbrella, sunglasses and other equipment.
4. Take emergency medicine with you
On the way to travel, it's easy to encounter changeable climate. The climate that is hot and cold is the most likely to catch a cold, and the weather that is hot and stuffy is the most likely to get heatstroke. Therefore, you should take some heatstroke medicine when you travel in summer. Such as Rendan, cool oil, golden oil, essential balm, ten drops of water, mint ingot, Huoxiang Zhengqi water, etc. In case of heatstroke, the patient should be carried to a cool and ventilated place to lie down and rest, then unbutton the patient's clothes, apply cold water towel on the patient's head and neck, and let the patient take some pills or ten drops of water.
Do you know how to give first aid after heatstroke?
1. Acupoint massage
If the heatstroke person has lost consciousness, it can be used to pinch the acupoints of Zhonghe and Hegu to make him awake and keep the respiratory tract unobstructed. The critically ill person should be sent to a doctor in time.
2. Cooling treatment
The rate of hypothermia determines the prognosis of patients. Usually, the rectal temperature should be reduced to 37.8-38.9 ℃ within one hour, and the temperature should be monitored continuously during hypothermia.
(1) quickly transfer the patient to a well ventilated low temperature environment, make him lie on his back, raise his head, take off his clothes, massage his skin and muscles, and promote heat dissipation.
(2) for heatstroke patients without circulatory collapse, cold compress on the head, place ice bags at the head, armpit, groin and other large blood vessels or immerse the body in 27-30 ℃ water to conduct heat dissipation and cool down.
(3) for those with circulation collapse, evaporation can be used to cool down. For example, 15 ℃ cold water can be used to wipe the skin repeatedly, and at the same time, electric fan and air conditioner can be used to cool down. However, it should be noted that it is not allowed to blow directly to the patient to prevent cold.
3. Replenish liquid
If the patient is conscious and has no nausea, vomiting and other symptoms, drink cold salt boiled water or other cool brine to cool down and replenish blood volume. If the patient can not drink water, intravenous drip of normal saline or Ringer's solution 1000ml (the dosage can be controlled according to the specific situation). Unless the patient has peripheral circulatory failure or massive vomiting and diarrhea, it is not necessary to input too much liquid to avoid heart failure or pulmonary edema.
