From age 70 onward, the system that regulates heat and cold becomes less efficient.
This means the body takes longer to adapt to temperature changes.
As a result, many older adults:
Feel cold when others do not
Overheat more easily
Sweat less, making it harder to cool down
This change is not just uncomfortable—it also increases the risk of heatstroke or hypothermia.
What helps
Dressing in layers, even indoors
Avoiding extreme temperatures
Staying well hydrated
3. Digestive changes that affect almost everyone
The digestive system also undergoes changes.
After 70, the stomach produces less acid, the intestines move more slowly, and the absorption of certain nutrients decreases.
This can lead to:
Feeling full quickly
Constipation
Deficiencies in vitamin B12, iron, or calcium
Many people assume it’s “normal to feel heavy,” but in reality, it’s a digestive system that now requires more care.
What helps
Eating smaller portions
Increasing natural fiber intake
Drinking water throughout the day
