Your 40s mark an exciting transition-not a decline, but an opportunity to optimize your health with the wisdom and resources you've built over the decades. Here's what you need to know to not just maintain, but enhance your wellbeing.

**Key strategies:**

**Sleep optimization**: 7-9 hours of quality sleep supports hormone regulation

**Stress management**: Chronic stress elevates cortisol, disrupting other hormones

**Regular check-ups**: Monitor thyroid, testosterone (men), and estrogen/progesterone (women)

The Cardiovascular Sweet Spot

Your 40s are prime time for cardiovascular disease prevention—and it's incredibly effective when you start now.

**Focus areas:**

**Heart rate variability training**: Mix high-intensity intervals with steady-state cardio

**Blood pressure awareness**: Optimal is <120/80; get checked regularly

**Cholesterol management**: Know your numbers and the difference between HDL and LDL

Bone Density: Your Future Self Will Thank You

Bone density peaks around 30 and begins declining, but it's not too late to strengthen your skeleton.

Action items:

**Weight-bearing exercises**: Walking, jogging, dancing, or resistance training

**Calcium + Vitamin D**: Ensure adequate intake through food and supplementation if needed

**Limit bone-depleting habits**: Excessive alcohol, smoking, and sedentary lifestyle
