- Sleeping under 6 hours is consistently linked to worse health and a shorter life.

- Regularity matters more than perfection.
- It's free, and works fast.
What happens when you sleep too little?
Even one night of too little sleep measurably impairs reaction time, memory and judgement. Over time, chronic sleep deprivation raises inflammation, blood sugar and stress hormones.
The habits that move the most
- Fixed bedtime and wake time, including weekends
- A dark, cool bedroom
- No screens or alcohol close to bedtime
- Daylight and movement early in the day
Quality, not just hours
It's not only about the number of hours, but about continuous, deep sleep. Biomarkers and a sleep assessment can reveal what poor sleep actually costs you.

Does measuring my sleep help?
A baseline picture via tests and markers makes the effect concrete, so you can see what changes actually do.
