Common changes that can occur after age 70 and why it’s important to know about them early

After 70, the body’s ability to manage heat and cold weakens. It adapts more slowly to temperature changes, which is why older adults often:

Feel cold more easily

Overheat faster

Sweat less, making cooling harder

This isn’t just uncomfortable—it raises the risk of heat exhaustion or hypothermia.

What helps

Wear layers, even indoors

Avoid extreme heat or cold

Stay well hydrated

3. Digestive changes become common

The digestive system also slows with age. Stomach acid production decreases, intestinal movement becomes less efficient, and nutrient absorption declines.

Common effects include:

Feeling full sooner

Constipation

Low levels of B12, iron, or calcium

This isn’t something to ignore—it’s a sign the digestive system now needs more support.

Helpful strategies

Eat smaller, more frequent meals

Increase fiber from natural foods

Drink water consistently throughout the day
