1. Decrease of amount of meals
We get water from meals in addition to drinks. If the amount of meals decreases due to summer heat fatigue, even if your water supply from drinks is the same, total supply of water decrease, causing dehydration. So if you can’t eat meals as usual, it is important to pay attention to drinking more water than usual.
2. Lack of salt
Drinking only water when you sweat causes cramps in the calves. Lack of salt makes calcium which controls the contraction of the muscles not reach the cell of the muscles. That causes malfunction of the muscles and the muscles are contracted too much, leading to cramps.
Aging cause the decreases of the liquid in the body. The amount of meals also decreases with aging, causing lack of water and salt. That easily causes dehydration, leading to heat stroke.
2 days after the highest temperature’s day, there are more people having heat stroke.
Aging makes the body extremely insensitive to heat. Even if the body temperature goes up, an old person doesn’t feel hot and stores heat in the body. An old person feels okay on the day of highest temperature, so the next day and the day after the next day they go out and store more heat in the body and the heat becomes peak in 2 to 3 days, causing heat stroke.
Talking can be a cause of heat stroke.
While we are talking, we are losing water from our mouth. People who talk a lot at the time of work need to be careful.
Stress causes the imbalance of the autonomic nervous system. That leads to the decline of the function to control the body temperature.
5. Sudden change in temperature
This is caused when you go to hot outdoors from a cool air-conditioned room.
6. Hot inside the room
Hot inside the room is the place that heat stroke occurs most. The kitchen is the most dangerous place because even if the room is air-conditioned, the kitchen where fire is used is very warm. When you prepare breakfast, you need to be careful because while you are sleeping, you are losing water.
7. Lack of sleep
Lack of sleep declines the function to control the body temperature as well as stress.
Drink good to prevent heat stroke
Mix of banana, yogurt and milk
Banana is rich in potassium which stores water.
Yogurt and milk contain albumin which is a type of protein and produces blood and controls the body temperature.
8. Over exercise
It is better to take a rest every 30 minutes under the sunshade.
9. Lack of water
Lack of water decreases the amount of blood and the function of the organs declines. It is good to supply water from drinks containing more than 40 mg of potassium such as sports drinks or Oral Rehydration Solution (ORS).
10. Direct sunlight
Exposing your body to direct sunlight stores more heat in the body than not exposing to direct sunlight even in the same temperature. That causes heat stroke more easily. When you go out under the direct sunlight, it is recommended to take 5 minutes rest every hour under the sunshade.
