Heat stroke is commonly known as severe heat stroke. Patients with heat stroke usually have high fever, body temperature above 40°C, dry and hot skin without sweat, mental disorders, organ failure, etc. If they are not treated promptly and properly, the mortality rate will be as high as 50%-70%. According to medical research reports, if the body temperature of heat stroke patients cannot be cooled down to normal within 24 hours, the mortality rate will be as high as 60%-80%. Outdoor sports enthusiasts are the high-risk group for heat stroke.
1. Depending on the symptoms of heat stroke, there are three levels:
1-1.Premonitory heatstroke
Symptoms include headache, dizziness, thirst, sweating, nausea, weakness in the limbs, and rapid pulse.
1-2.Mild heatstroke
Inattention, uncoordinated movements, and blurred consciousness. Cold and wet skin, body temperature is often above 38 degrees, flushed face, heavy sweating, hot skin, and other symptoms.
1-3.Deep heatstroke
Heatstroke, thirst, and muscle cramps (commonly known as cramps). Sunstroke: direct exposure to the sun can cause damage to brain cells. Heat exhaustion: excessive dehydration and lack of salt. Heatstroke: excessive physical exertion under high temperatures.
The mortality rate caused by severe heat stroke is extremely high. How can people who like to engage in outdoor sports prevent it? Here are 5 simple heat-avoiding tips to keep you away from the door of life and death.
2. 5 ways to prevent heat stroke:
Tip 1: Avoid the scorching sun
The main cause of heat stroke is prolonged exposure to the scorching sun, so you should avoid the sun when traveling in hot weather, especially between 10 a.m. and 4 p.m. Cyclists who are weak and sick but love cycling should try to reduce going out as much as possible during the hot sun. If the high temperature can't stop the "unrestrained heart" of leisure cyclists, it is recommended to bring a lightweight hammock or canopy. Once the sun is shining directly on your head, quickly find a place with lush trees, green water and chirping cicadas to take a rest to avoid the heat.
Tip 2: Sun protection
When going out, you should prepare your cycling sun protection equipment. You can wear cycling clothes with UV protection and good breathability. Then apply sunscreen. Even men with strong bodies should take the above protective measures. Many people mistakenly believe that sunscreen can prevent sunburn and naturally prevent heatstroke, so they apply a thick layer or cover their whole body with cooling oil to cool down. In fact, these practices not only do not prevent heatstroke, but can cause heatstroke. Thick sunscreen covering the skin will affect the discharge of sweat, which will naturally lead to slow heat dissipation. Similarly, applying cooling oil all over the body will reduce the discharge of sweat due to the cool feeling.
Tip 3: Replenish water and eat heat-resistant fruits
When traveling in high temperatures, you must develop a good habit of drinking water. Don't wait until you are thirsty to drink water. It is recommended to drink sports drinks, because sports drinks contain oligosaccharides in glucose units, electrolytes such as potassium and sodium, which are easily absorbed by the body and can balance the electrolytes in the body without causing dehydration. Or drink more refreshing tea containing salt. In a high temperature environment for 1 hour, the human body can sweat up to 1 liter. Replenishing water must follow the principles of "timely" and "small amounts and multiple times".
During riding uphill ebike, you should replenish about 200cc-300cc of water every 15 minutes, just like drinking one-third of the capacity of a mineral water bottle. Don't drink too much each time, and replenish it in multiple times. Although it is also important to replenish water when you find heatstroke, if you vomit violently and cannot replenish water on your own, you should go to the doctor in time and seek medical intervention to replenish water for the body. If you ride for leisure, you might as well bring some heat-resistant fruits on the road, such as juicy and sweet watermelon, which is not only cool but also replenishes energy.
Tip 4: Essential heatstroke prevention medicine
When traveling in summer, you should carry with you the family's usual anti-heat medicines, such as Ren Dan, Shi Di Shui, Huo Xiang Zheng Qi Shui, Qing Liang You, Wu Ji Dan, etc. Once the symptoms of heat stroke appear, you can take anti-heat medicines to relieve the condition.
Tip 5: Be aware of your physical condition when traveling
The high temperature season is also a high incidence period for diseases. People with cardiovascular diseases, those recovering from serious illnesses, and those who are weak should travel within their capabilities and enhance their awareness of protection. When riding outdoors, if you feel dizzy and weak, chest tightness, panic, and shortness of breath, some people may also have flushed faces, heavy sweating, and accelerated heartbeats. If you continue to hold on at this time, you may experience symptoms of heat stroke and cause serious consequences. Once the above signs of heat stroke appear and you feel unwell, you should quickly evacuate the high temperature environment and choose a cool and ventilated place to rest; drink more salty cool tea, and you can also apply cool oil, wind oil, etc. on the forehead and temples, or take Chinese medicine such as Ren Dan, Shi Di Shui, and Huoxiang Zhengqi Shui.
In addition to the hot summer,
People who do outdoor sports are prone to heat stroke. After autumn, the temperature difference between day and night becomes larger, but it is sometimes still very hot during the day, especially when it is sunny and rainy for a long time after autumn, the heat is more oppressive, and if you are not careful, you may also suffer from heat stroke. Therefore, I would like to share a line from a movie with readers who love cycling, "Don't mess yourself up in order to win", so that you can ride your bike happily in a safe environment.
