Elderly at Risk of Undetected Heat Stroke Due to Reduced Sweating – Families Miss Warning Signs

Summary

Seniors over 70 lose the ability to sweat efficiently, making heat stroke hard to detect using standard signs. Families rely on looking for sweat, but elderly can have cool, dry skin while experiencing severe overheating. This hidden danger is exacerbated by medication degradation in heat (insulin, biologics) and lack of nighttime cooling during heat domes. Existing monitoring solutions do not account for this biological change, leaving seniors vulnerable to fatal heat stroke without obvious symptoms.
