The hydrangea wet in the rain has become a beautiful season. Did you know that it's easy to get heatstroke during this season, when the temperature difference is large and the humidity is high? It can be difficult to imagine the causes and symptoms of heatstroke correctly, and the symptoms can get worse without you noticing it. We hope that this article will serve as a trigger or hint for heat stroke prevention.

What is heat stroke?

It is a general term for disorders that develop when the body loses water and salt in a hot and humid environment, or when the body's adjustment functions do not work properly. Especially during this time when the body is not accustomed to the heat, it is necessary to be careful not only outdoors but also indoors.

Typical symptoms of heat stroke

・Dizziness ・Lightheadedness ・Facial hot flashes ・Numbness in limbs ・Muscle spasms ・Headache ・Nausea ・Fatigue Lightheadedness on standing up and hot flashes on the face are early symptoms of heat stroke, and are signs to be aware of. As soon as you notice the signs, put yourself in a cool environment and replenish fluids and salt.

Occurs more often indoors

Be especially careful this summer when "home time" is getting longer due to the corona sickness! It is indoors where care for heatstroke tends to be neglected. As mentioned above, heatstroke is caused by sweating and lack of water intake, which reduces the water content in the body and makes it easier for heat to accumulate in the body. Without realizing it, the indoor environment becomes hot and humid, and it is easy for people to become less conscious of actively drinking water. Especially in the summer, it is said that you sweat about 0.5 to 1 liter when you sleep, so be careful. (There are individual differences depending on room temperature, humidity, age, etc.)

To prevent heat stroke

In addition to "avoiding the heat" and "frequently replenishing water", it is important to keep in mind "building a body that can withstand the heat" on a daily basis. When temperatures and humidity rise, our bodies adjust to accommodate the changes. Vitamins and minerals are responsible for this adjustment. Together with high-quality protein, it is an important nutrient for building a body that can withstand the heat. When the subjective symptom of "thirsty" appears, it means that the body is quite dehydrated. The point is to be conscious and keep hydrated frequently. It is recommended to supplement with salt (sodium) and citric acid. Small stacks such as hydration like this lead to protecting your precious body. <Reference> Points for heat stroke prevention actions in the Ministry of Health, Labor and Welfare's "New Lifestyle" Ministry of the Environment heat stroke prevention website
