It is getting hot!
In the beginning of summer, it is difficult for our body to adapt to sudden elevation of the temperature because our body has not been used to it.
So we have more possibility to have heat stroke.
You may think that heat stroke only happens when you are outside on a hot day, but even if you are in the air conditioned room, you have a risk to have heat stroke because the temperature near the window is as high as the one outside.
What happens when we have heat stroke?
The lightest symptom is heat syncope which is fainting or dizziness as a result of overheating.
Why does heat syncope happen when you have heat stroke?
When your body temperature elevates due to the heat, blood flow on the surface of the skin increases to release the heat and the blood flow in the brain decreases, resulting in fainting.
Which is better for water supply at home or in the office? (A) Water (B) Tea
The answer is (A) Water.
Since tea contains caffeine which has a diuretic effect, if you drink it too much, water is excreted as urine.
Therefore, water is better, but the temperature of the water is also important. If the water is cold like iced water, the stomach shrinks and it becomes a burden on the stomach. The proper temperature of water is 5-15 degrees C (40-60 degrees F) because its rate of absorption is good and it is effective to cool the body.
The quantity to drink at a time should be 150-250 ml (5-8.5 fl oz) and it is better to drink often. If you drink too much at a time, your body can’t absorb the water.
Oral Rehydration Solution is drinking water with modest amounts of sugar and salt added, which is used to treat and prevent dehydration.
Recipe of Oral Rehydration Solution you can make easily at home
Mix the following materials.
Water: 1 litter (1 qt)
Sugar: 20-40 gram (0.7-1.4 oz)

How to build up the body unlikely to have heat stroke
Making the body easily sweat is important because the body becomes strong against heat.
(1)Interval fast walking
Interval fast walking is a walking exercise that fast walking and slow walking are performed alternately 3 minutes each. The purpose of Interval fast walking is to train the muscles of the legs and increase the blood flow. As a result, you will be able to return blood to the whole body, especially to the brain.
Fast walking: walk with wide strides and pace to pant.
Slow walking: walk with looking around like taking a walk.
(2)Drink a glass of milk
It is effective to drink a glass of milk within 1 hour after the interval fast walking. It helps repair the damaged muscles.
If you continue the above for 10 days, you can increase the amount of blood flow. However, it is dangerous to exercise under the blazing sun, so please walk when the air temperature is low such as early in the morning or in the evening.
