How to protect your loved ones from extreme heat this summer

Published on June 02, 2026 | Translated from Spanish

With the arrival of summer, at Foro3D we recommend paying special attention to vulnerable people, such as children, the elderly, and people with chronic illnesses. High temperatures are not just a nuisance; they can pose a real health risk. Therefore, it is advisable to take preventive measures and know the warning signs of heatstroke.

IoT sensors and apps to monitor home temperature 🌡️

Current technology offers practical solutions to mitigate the effects of heat. Low-cost IoT sensors, such as those based on ESP32 or similar, allow real-time monitoring of temperature and humidity. You can integrate them with platforms like Home Assistant to activate fans or send alerts to your phone when temperatures exceed 30 degrees. There are also apps that remind you to hydrate periodically, useful for elderly people living alone. Implementing these systems does not require extensive technical knowledge and can make a notable difference.

Air conditioning: that friend who ruins your bill 💸

Of course, there is always the option of setting the air conditioning to 16 degrees and living like a yeti in a polar cave. Then the electricity bill arrives, and you have to choose between eating or not melting. If you prefer not to sell a kidney, try sealing windows, using awnings, and turning it on only during off-peak hours. Or, if you are more old school, a ceiling fan and a wet towel on the back of your neck. It is not glamorous, but it works.
