Cortisol: understanding and regulating the stress hormone
It's called "the stress hormone", but cortisol isn't an enemy: it's vital. The problem is its chronic excess. Understanding its role and knowing how to regulate it naturally is the key to a calmer mind and better energy.
What is cortisol for?
Secreted by the adrenal glands, cortisol follows a natural rhythm: high in the morning to wake us up, low in the evening to prepare for sleep. It mobilises energy, regulates inflammation and helps us react to a threat. In itself, it's essential.
When cortisol becomes a problem
It's chronic stress that throws everything off. Persistently high cortisol can show up as:
- Persistent fatigue, especially on waking
- Sleep problems and night-time waking
- Sugar cravings and abdominal weight gain
- Irritability, anxiety, mental fog
How to regulate your cortisol naturally
Good news: lifestyle has a direct impact. The most effective levers are sleep, moderate physical activity, a diet stable in sugars and reducing stimulants. Our 7 anti-stress solutions detail each of these points.
The role of adaptogens
Adaptogenic plants help the body better regulate its stress response. Ashwagandha is particularly documented for its action on cortisol. You'll find it, with reishi and saffron, in our CALM gummies.
Where to start?
Start with sleep and reducing stimulants, then add adaptogen support. Discover the Calm & Sleep collection or take the BIEN quiz.
Frequently asked questions
How do I know if my cortisol is too high?
Fatigue on waking, sleep problems, sugar cravings and irritability are telling signs. Only a medical test can measure it precisely.
Does ashwagandha lower cortisol?
Several studies suggest a reduction in cortisol with regular ashwagandha intake. It's one of its most documented effects.
Does exercise raise cortisol?
Intense, prolonged activity can raise it temporarily. Moderate, regular activity, on the contrary, helps regulate it better.
