“Not even magnesium was helping me… then I found Third Hour! When I wake up, I immediately put on the mask and fall asleep in minutes… no more rolling and scrolling.”
Adele F.
“I usually end up on my phone for an hour or two when I wake up. I put this on and was back asleep in about 15 minutes.”
Sonya
“I woke up at 2 a.m. and struggled to get back to sleep. I put the mask on and it felt so good. It warmed up quickly and stayed warm for a while… I fell back asleep.”
Debbie
Who is it for?

Anyone who falls asleep fine, then wakes between 2 and 4 a.m. and can't settle again.

If you reach for your phone or start counting the hours until the alarm, this is for you.

What does it feel like?

Like being wrapped up and held. The warmth spreads slowly across your eyes, your shoulders drop, and the room goes dark and quiet.

For those few minutes there is nothing you have to do.

What is it?

A sleep mask that warms itself when you open it. It blocks the light and wraps the area around your eyes in gentle warmth for up to 30 minutes.

Each mask is individually wrapped.

How do I use it?

Keep it beside your bed. When you wake, tear it open, loop it over your ears and lie back. No phone, no light, no getting up.

Within a minute you feel the warmth begin, and you can let your body sink back into the bed.

Is it safe?

Yes. There are no batteries and nothing to plug in, charge or microwave.

The warmth comes from a gentle air-activated reaction, like a hand warmer. Each mask is used once.

Which one should I choose?

New to Third Hour? The 7-Mask Trial lets you try it.

The Starter Ritual adds the Ritual Box for your bedside. The Bedside Ritual is our recommended supply of 30 masks, and the Complete Ritual is the lowest price per mask.

You wake up. You check the time. 2:17 a.m. And suddenly your mind switches on. Thinking. Planning. Replaying everything. And once it starts... it doesn't stop. This is the moment this mask is built for.

What to expect

What the first nights feel like

Nothing to learn and nothing to set up. Here is what it is like from the first wake-up.

Not for you? You have 60 nights to decide.

Try It Risk-Free
  1. The first wake-up

    You wake. You reach to the bedside table, tear one open and slip the loops over your ears. Within a minute the warmth starts to spread across your eyes. Your shoulders drop. It is dark, it is warm, and there is nothing you have to do.

  2. The first week

    It becomes the thing you reach for. No phone. No checking the clock. No getting out of bed. Just the same small ritual, every time you wake.

  3. After that

    Some nights you will wake and some you will not. On the nights you do, it is already there beside you.

Not for you? You have 60 nights to decide.

Customer video review of The 2–4 a.m. Reset

I usually wake up around 2am... can't fall asleep...keep rolling...then grab the mobile and scroll .... then falling asleep 5am and wake up again at 6. Not even magnesium was helping me. ... then I found THIRD HOUR!!! When I wake up, I immediately put on the mask and fall asleep in minutes... no more rolling and scrolling. This means I have wonderful energetic days. I wish everyone will try this. It works from the first night.

Ayesha P. 5/5 Verified

The 2–4 a.m. Reset

Absolutely love this sleep mask. It’s incredibly comfortable, soft on the skin and blocks out the light really well without feeling too tight or putting pressure around my eyes. I’ve been sleeping much better since using it, especially when travelling or having a daytime nap. The quality feels great and it stays in place throughout the night. Definitely one of the best sleep masks I’ve used — highly recommend!
