  • You wake up already tired

  • You wake up drenched

    Heat rises from the mattress, the duvet holds it in. At 3 a.m. you're hunting for the cool side.

  • You stare at the ceiling

    The screen follows you behind your eyelids. Your mind starts looping. An hour goes by.

  • Noise is stealing your nights

    A neighbour, a street, a ringing in your ear. Eight hours in bed — and exhausted.

  • You wake up with a creased face

    Creases on your cheek, dull skin, tangled hair. Cotton leaves marks.

The science of sleep

Sleep is the first treatment

For a long time the night was treated as lost time. The research of the last fifteen years says exactly the opposite: it is when the body cools, repairs and rebuilds itself.

Life expectancy

That is the additional life expectancy observed in men combining five good sleep markers — 2.4 years in women. All-cause mortality falls by 30%.

The threshold for falling asleep

Core body temperature has to fall by about one degree for sleep to take hold. That is the whole reason our cooling range exists — and why a bedroom should sit between 15.6 and 19.4 °C.

Physical recovery

The share of daily growth hormone secreted during sleep, peaking in the first deep cycle. It is at night that muscle and tissue repair themselves.

It all starts with the night.

A restored night makes for a lighter day. Patience with your children. Energy at 6 p.m. A mood that no longer depends on the night before.

The quality of your sleep decides the quality of your life. It is not a detail — it is the foundation.
