Why are elderly people more susceptible to heatstroke? Four reasons why it's dangerous even indoors, and how to prevent it.

4 reasons why it's dangerous even indoors

• The ability to sense heat decreases, delaying the timing of using air conditioning.
• You may not feel thirsty as easily, and hydration may be delayed.
• The body's ability to regulate temperature weakens, making it easier for heat to build up.
• "Using the air conditioner is a waste of money," so I endure the heat.

Measures you can start today

• Using the air conditioner without strain
• Drink water little by little before you feel thirsty.
• Change your clothes if you sweat.
• Avoid going out during the hottest part of the day.

Small changes, such as "not being as energetic as usual" or "having a poor appetite," are things that only family members can notice. In the summer, clothes are easy to change, and clothes that can be put in a dryer are also useful in care facilities.
