Waking at 3am, carrying stress in your face and belly, feeling wired-but-tired: these are the classic signs people associate with chronically elevated cortisol.
There's a lot of nonsense in this space. Here are seven approaches with actual evidence behind them — ranked from foundational to supplemental.
The foundations (do these first)
1. Sleep consistency — going to bed and waking at the same time regulates your cortisol rhythm more than any supplement.
2. Morning daylight — 10 minutes of outdoor light anchors your cortisol awakening response where it belongs: the morning, not midnight.
3. Caffeine timing — caffeine spikes cortisol. Keep it before noon, and consider cutting the second cup if you're anxious.
4. Walking and breathwork — even 10 minutes of walking or slow breathing (longer exhales than inhales) measurably reduces acute stress.
The supplements with real evidence
5. Ashwagandha — the most-studied supplement for cortisol, with multiple trials showing meaningful reductions at 300–600mg of standardized extract daily.
6. Holy basil (tulsi) — clinical evidence for cortisol reduction and stress resilience; gentler than ashwagandha and fine for daytime.
7. Magnesium — stress depletes it, and low magnesium worsens the stress response. Glycinate in the evening is the popular choice.
