Working outdoors in the summer can drain not only your physical strength but also your mental energy. In particular, Japanese summers are hot and humid, so if you're not careful, you can easily get sick.
So this time, we've put together an easy-to-understand summary of how to reduce the heat when working outdoors, covering everything from the risks of heatstroke to effective countermeasures, useful items, and even popular cooling products.
What is heat stress and why is it dangerous?
"Heat stress" is a condition in which the body is put under strain by being in a hot and humid environment for a long period of time. Specifically, when the temperature and humidity are high, the body's thermoregulation system does not work properly, making it easier for heat to build up inside the body.
In mild cases , symptoms include a general feeling of fatigue and constant sweating , but in severe cases, it can cause headaches, nausea, dizziness , and in the worst cases, heatstroke .
The risk of heat stress is particularly high when working or attending outdoor events, so it is important to take proper precautions.
How body temperature is regulated
When it's hot, the human body sweats, and the sweat evaporates, releasing body heat through a process known as " latent heat of vaporization ," which regulates body temperature. On the other hand, when it's cold, blood vessels constrict to prevent body heat from escaping.
However, in a climate like Japan where humidity is high, sweat does not evaporate easily, and heat tends to build up inside the body. Therefore, when spending time outdoors, it is important to find ways to stay cool and cool your body at the right time without overdoing it.
How to stay cool when it's hot outdoors
Here are some ways to beat the heat when working outdoors:
1. Replenish your fluids and salt intake frequently . Drink water before you feel thirsty, and replenish with salt candy and sports drinks.
2. Take breaks in the shade or cool places and cool down every 30 minutes to an hour.
3. Wrapping a cooling towel or wet towel around your neck can lower your perceived temperature.
4. Cooling products that use evaporative cooling are also easy to use and recommended .
Just being aware of these things can greatly reduce the strain on your body.
