Cortisol is your body's main stress hormone. It's not bad — it's how you wake up in the morning, push through a hard workout, and respond to challenge. The problem is the modern version of stress: low-grade, constant, and rarely resolved. When cortisol stays elevated for months and years, metabolism takes the hit.
What chronic cortisol does
- Raises blood sugar and worsens insulin resistance
- Promotes fat storage, particularly around the midsection
- Disrupts sleep — making everything else harder
- Suppresses thyroid and sex hormone production over time
- Drives cravings for sugar, salt, and fat
What actually helps
- Protect sleep like it's medication — same bedtime, dark room, no screens late
- Daily nervous-system downshift: walks, breathwork, sauna, time outside
- Strength training, not punishing endurance work, during high-stress seasons
- Caffeine after food, not on an empty stomach
- Saying no to one thing per week you'd usually agree to
