East heat, heatstroke is likely to occur
Dr. Dang Hoang Diep - Emergency Department, Central Hospital for Tropical Diseases said that prolonged, severe sunny periods are the time when heat and thunderstorms are likely to occur. This is not only a condition that causes fatigue, dizziness, or lightheadedness, but also carries the risk of nerve damage, multiple organ damage, and even death if not treated promptly.
Heating is a condition of increased body temperature due to too hot an environment or physical activity that is too much, beyond the body's ability to regulate heat. If not treated promptly, it can progress to heatstroke when the body temperature exceeds 40°C accompanied by neurological, circulatory, and respiratory disorders.
Hot flashes often occur in the afternoon in humid, unbreathed environments; and hot flashes are often experienced in the middle of the day when the sun is strong and the outside world is bright.
" Heat shock is a condition in which the body's temperature suddenly increases above 40°C due to prolonged exposure to heat that the body has not yet adapted to. sweating too much causes dehydration, electrolytes, and disruption of the brain's thermopolitical center.
heatstroke often occurs in outdoor workers, athletes, and workers working at high intensity in hot weather. At that time, the body cannot cool down on its own, leading to continued temperature increase, endangering life.
Initial symptoms include: cramps, thirst, dizziness. If more severe, it can be confused, bewildered, convulsive, coma, or even sudden death. Some accompanying symptoms: migraine, nausea, shortness of breath, facial hot flash," Dr. Dang Hoang Diep added.
People at high risk of heat stroke are those working in hot environments such as farmers, high-pressure workers, athletes practicing outdoors...
heatstroke can happen to anyone, but children, the elderly, and adolescents who practice sports in the sun are the most vulnerable groups. Healthy young people are often subjective, ignoring the initial signs, so they are easily in a dangerous situation.
People with heat and fever can experience mild to severe symptoms such as red skin, rapid heartbeat, sluggish breathing, dizziness, headache, nausea, sweating, low blood pressure, confusion, confusion, confusion, seizure, coma, blood clotting disorder, multiple organ failure leading to death if not treated promptly.
"During hot days, many people still have to work outdoors such as farmers, construction workers, and people traveling on the road. Avoid going out from 11am to 3pm - the time when the sun is strongest. When working outdoors, wear protective gear, cover thoroughly, and take a break of 1015 minutes after each period to cool down and replenish water. Each person should drink 2.53 liters of water per day.
First aid when meeting a person with heat stroke: Quickly take the victim to a cool place, take off clothes, use a fan and a handbag to clean the whole body. If you are still up, drink cool water. Call the 115 emergency room or take it to the nearest medical facility for timely treatment," Dr. Dang Hoang Diep recommended.
