2. Temperature Regulation Becomes Less Reliable

After 70, the body adapts more slowly to changes in temperature. The ability to conserve heat or cool down efficiently weakens.

Common experiences include:

Feeling cold more easily
Overheating faster
Sweating less, which makes cooling harder

These changes are more than uncomfortable. They increase the risk of heat exhaustion in summer and hypothermia in colder weather.

What helps

Dress in layers, even indoors
Avoid extreme heat or cold when possible
Stay well hydrated throughout the day
