2. Fluctuating Temperature Regulation
The body’s “internal thermostat” becomes less efficient with age. The ability to sweat (to cool down) or constrict blood vessels (to stay warm) slows down, making extreme temperatures more taxing on the system.
- What to expect: Feeling chilled indoors or overheating quickly during summer months.
- Proactive Habits: Dress in breathable layers and prioritize hydration, as water is essential for internal temperature management.
3. Digestive Efficiency and Nutrient Absorption
Digestion naturally slows as stomach acid production decreases and intestinal motility wanes. This can lead to a “full” feeling earlier in meals and a decline in the absorption of critical nutrients like Vitamin B12, Iron, and Calcium.
- What to expect: Occasional constipation or unexplained fatigue due to nutrient gaps.
- Proactive Habits: Opt for smaller, nutrient-dense meals throughout the day rather than three large ones. Focus on high-fiber foods and consistent water intake
