Stress isn't the enemy, it's what makes you perform. The problem arises when a break never comes, and the body stays on high alert around the clock.

- Cortisol is useful acutely, but harmful when persistently elevated.
- Chronic stress hits sleep, blood sugar, weight and the heart.
- It's measurable, and modifiable without quitting your job.
- Small, regular breaks beat big, rare ones.
What does cortisol do?
Cortisol mobilises energy and sharpens focus in pressured situations. But chronically elevated, it disrupts sleep, raises blood sugar, promotes fat accumulation around the belly and strains the heart.
The signs you shouldn't ignore
- Waking tired despite enough hours
- Hard to "wind down" in the evening
- Cravings for sugar and caffeine
- A shorter fuse than usual
What actually works
Not a weekend at a wellness hotel, but daily micro-breaks, a fixed sleep rhythm, movement and breathing exercises. The effect is measurable on sleep, resting heart rate and inflammation.
Frequently asked questions
Can you measure my stress level?
We measure related markers, including cortisol and inflammation, and link them to sleep and cognition for a complete picture.
Do I have to slow down to fix it?
Rarely entirely. It's often about better recovery around the load, not less ambition.
