Information and resources
site for heatstroke
prevention“Heatstroke” refers to a condition in which body heat is trapped in the body due to poor bodytemperature regulation by sweating in a hot and humid environment. It can occur not only when you
are outdoors, but also when staying indoors not doing any exercise or work. Heatstroke sufferers
may be taken to hospital by ambulance and in some cases die from it. In order to prevent healthproblems caused by heatstroke, each individual should have a correct understanding of heatstroke,
be aware of changes in their physical condition, and look out for those around them.

mindful of changes in your physical condition.

Even if you do not feel hot, check the room temperature and ambient temperature, and try to adjust the temperature using
electric fans and air conditioners.

Elderly people, children, and those with disabilities need to be especially kept an eye on!
Caution is necessary since elderly people are less able to sense the heat and a lack of fluids, and their body’s ability to regulate heatis impaired. Also, children need to be kept an eye on since their body temperature adjustment functions are not fully developed yet.
In addition, for those with disabilities, it may be difficult to regulate their body temperature, they may not notice when they arethirsty, or they may not be able to take fluids by themselves so caregivers and people around them should be keep an eye on them.
