Helpful habits

• Get morning sunlight
• Limit bright screens in the evening
• Keep consistent sleep and wake times

2. Temperature regulation becomes less reliable

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

4. Balance declines—but it can improve

Loss of balance is one of the most serious changes after 70. It’s caused not only by muscle loss, but also by changes in vision, the inner ear, and reaction time.

The encouraging news: simple balance training can lower fall risk by nearly half.
