Lumera Cool — Cooling & Total Blackout Hood
Some days don't end when you turn off the light. Your head is still switched on, your eyes are sore from the screen, and you can feel the tension sitting in your temples.
Cool isn't an eye mask. It's a gel hood that wraps your whole head — forehead, temples and eyes — combining three things at once: cold, total darkness, and gentle, even pressure. Put it on for twenty minutes and the world switches off.
Cold or heat, you choose
Keep it in the freezer and it comes out genuinely cold, not lukewarm. Twenty seconds in the microwave and it gives off enveloping heat. The same piece works at the end of a long day and on a winter morning.
It adapts, it doesn't squeeze
The elastic fabric follows the shape of your head with no straps or buckles digging in. The pressure is constant and evenly spread — more like a hug than a tight band. And because it covers down to your nose, the darkness is total even with light in the room.

The body cools down before it falls asleep.
Temperature sets the clock
Core body temperature drops a few tenths of a degree in the hours before sleep. It's not a consequence of falling asleep: it's one of the signals that precedes it. Cooling the forehead and temples supports a process the body is already trying to do on its own.
The light that keeps getting in
The retina keeps registering light even with your eyes closed. As long as there's brightness, the signal reaching the internal clock reads as day. Coverage that extends below the nose closes the gaps any mask resting only on the eye socket leaves open.
Pressure spread out, not squeezed
The elastic fabric spreads pressure across the whole surface instead of concentrating it on two points. It feels like a constant hug rather than a tight band, and when you take it off there's no crossed elastic mark left on your temple.
The hot head from screens
Prolonged screen use causes asthenopia: dry eyes, tension across the forehead and a feeling of heat around the eyes. Covering closed eyes with gentle cold is one of the simplest ways to cut that buildup at the end of the day.
Lumera Cool is a wellness and comfort product, not a medical device, and is not intended to treat any condition. Always check the temperature before applying it to skin.
Cold, pressure and darkness at the same time.
Gel across the whole surface
No loose gel packs at specific points: the entire hood is gel. Cold reaches the forehead, temples and eyes equally, with no dead zones.
Cold or heat
Straight from the freezer it comes out truly cold, not lukewarm. Twenty seconds in the microwave and it gives off enveloping heat. The same object for the end of a long day and for a winter morning.
Even compression
The elastic fabric holds evenly across the whole head. No straps, no buckles, no single point where pressure builds up and starts to bother you.
Darkness included
It covers down to the nose, so it switches off light at the same time it lowers the temperature. No need to add a sleep mask on top.

There's always light at the end of the road.
Less of it with Lumera.
Real darkness plus calculated weight that calms your nervous system while you sleep. It's not just another mask: it's the only one that feels like someone holding you to sleep.

The more pieces, the cheaper the system.
Each piece switches off a different signal: light, noise, heat, friction. Add the ones you're missing and the discount applies automatically in the cart.
