The Expat’s Guide to Japan is now sharing information on how to prevent, deal with the viruses and so on with the help of Smart119.

The 7th topic in the series is “How to Prevent Heatstroke During Corona Disaster”.


Wearing a mask has almost become a common manner, but in the heat and humidity of the Japanese summer, it is not easy to keep it on.

Let’s take a look at how to prevent heat stroke in the Corona era.


What to pay attention when wearing mask: It’s hot, it’s hard to breath, but it’s important!

・Mask increases heart rate and breathing rate, and may give high impact on your body.

・Breathing helps to release heat from your body, but mask may prevent from doing so.

・Dryness of the mouth does not indicate when to hydrate, so be sure to take fluid with added salt as often as possible.

・If you feel uncomfortable with your mask, it is important to take it off to rest by practicing appropriate social distance and coughing etiquette.

・Temperature of your face skin is plus 1.76℃.

・Use masks wisely to prevent COVID-19.



What to pay attention when using air conditioner: Make sure to open up the windows to ventilate air!

・Many air conditioners do not have air ventilation system, so make sure to get some fresh air once in a while.

・You need to be extra cautious during the season when your body is not used to the heat.

・It is also good idea to use fans and circulators.



Call and text your friends and families, or check each other’s social medias frequently to see if they are staying healthy.

Call and text your friends and families

Give and receive each other’s contacts to get in touch in case somebody falls ill.

Symptoms such as fever and fatigue are very similar to that of COVID-19, so be sure to record how long you’ve been having fever for, if you have breathing difficulty, any changes in health conditions, and whether you had contact with corona patients.

These would be very useful information.



It is now especially crucial to prevent heatstroke by “caring about each other’s”.

The heatstroke often hits elderly people inside the house who are considered to be most vulnerable to the heatstroke. It is important to prevent heatstroke by getting in touch with each other and be precautious by keeping appropriate distance.

Keeping social distance with other people and wearing masks may hide the sign of danger from people around you, and cause to delay the treatment. So make “social distancing” to “physical distancing”, so you won’t lose the connection to your loved ones!
