Most health advice is either too extreme or too vague to stick.

After 35, your body starts operating differently — recovery slows, inflammation increases, and small habits compound faster (in both directions). Here's what the research actually says matters most:

1. Consistent sleep schedule over sleep duration

Your circadian rhythm regulates hormones, immune function, and cellular repair. Irregular sleep times are independently linked to increased inflammation even when total hours are the same. Lock in your wake time first — the rest follows.

2. Zone 2 cardio, not just HIIT

High-intensity training gets the press, but 150–180 min/week of low-intensity (conversational pace) cardio builds mitochondrial density and preserves metabolic health long-term. It's boring. It works.

3. Protein: most people eat too little, not too much

0.7–1g per lb of bodyweight supports muscle retention as you age. After 35, muscle loss accelerates — this is the #1 lever to slow it. Distribute it across meals.

4. Stress management is not optional

Chronic cortisol degrades bone density, gut health, and immune response. 10 minutes of structured breathwork daily has measurable cortisol-lowering effects within 8 weeks.

5. Morning sunlight, evening darkness

Morning light resets your cortisol curve and improves nighttime melatonin. 10 minutes outside before 10am consistently outperforms most supplements for energy and mood.

These aren't hacks. They're the foundation. Get these right, and everything else you do for your health works better.
