Turn on the air conditioner too low
Many people have a habit of turning on the air conditioner at a very low level after returning from hot weather to cool down quickly. However, the excessive temperature difference between outdoors and indoors can prevent the body from adapting in time.
Sudden temperature changes easily cause vasoconstriction, dizziness, especially dangerous for the elderly, young children or people working outdoors for a long time.
Experts recommend keeping the air conditioner at about 26–28°C. When you first get home, you should sit down to rest, turn on the fan or open the door for your body to cool down gradually before using the air conditioner.
Drink cold beer to cool down
After going outdoors in the hot sun, many people choose cold beer instead of filtered water because of the immediate cool feeling. However, experts warn that beer does not help cool down as many people think.
Beer contains alcohol and has diuretic effects, causing the body to excrete water faster through urine. Meanwhile, hot weather has caused the body to lose a lot of water and electrolytes through sweat. If you drink a lot of beer at this time, the state of dehydration will be even more serious, easily causing fatigue, high blood pressure, cardiovascular disease and increasing the risk of stroke.
In addition, beer also causes the liver and kidneys to work harder while the body is exhausted from prolonged heat.
Doctors said that the feeling of "thirsty", "less hot" after drinking cold beer is only a temporary feeling. People with underlying diseases such as high blood pressure, cardiovascular disease, diabetes need to limit the use of alcoholic beverages in hot weather.
Instead of drinking beer or water that is too cold, people should drink cool water, light warm water and drink in small sips so that the body absorbs it slowly.
Shower immediately after sunbathing
Another common mistake is showering right after going out in the hot sun and coming home.
At this time, the body is secreting a lot of sweat, the blood vessels under the skin dilate to radiate heat. If you splash cold water suddenly, the blood vessels may contract quickly, causing blood pressure to change abnormally, causing dizziness or more dangerously, stroke.
Experts recommend resting for about 15-20 minutes in a cool place, drying sweat and stabilizing body temperature before bathing.
