Best Cooling Pregnancy Pillows

The short answer

Why pregnancy runs you hot

Your metabolic rate rises, your blood volume increases substantially, and your body is running a second circulation. MedlinePlus lists feeling warmer and sweating more among the ordinary symptoms of pregnancy, and night sweats are common and usually unremarkable.

Then you add a large pillow. A U-shape surrounds you with filling on both sides, which is excellent for support and does exactly what insulation does. That is the tension this page exists to navigate, and it is a genuine trade rather than a marketing problem.

What a cooling cover actually does

Cooling fabrics work in two ways: they conduct heat away from your skin faster than cotton or jersey does, which makes them feel cool when you first touch them, and some wick moisture more effectively.

What they do not do is remove the heat from the system. Once the cover has reached your body temperature — which takes minutes — the cool-to-touch effect is gone, and you are left with the fill's insulating behavior. That is why the honest ranking on this page gives the best heat score to the pillow that uses the least material rather than the one with the cleverest cover.

The things that work better than a cooling pillow

Said plainly, because a page about cooling pillows that pretends they are the answer would be less useful.

• Use less pillow. A wedge under the bump plus a knee cushion leaves air all around you. A U does not. This is the single biggest lever.
• Cotton or bamboo sleepwear instead of synthetic. Cheaper than any pillow and a bigger difference. It also helps with the itchy stretched skin that goes with a growing bump.
• A cooler room beats cooler bedding. A fan moving air across you does more than any fabric, and it is worth the noise.
• Lighter duvet, layered. Two thin layers you can shed one of beats one thick one, because your temperature changes through the night.
• A wedge rather than a wrap. If you have been using a U mainly for belly support, a wedge gives you most of that benefit with a fraction of the insulation.

How we picked

Six axes, with heat weighted hardest and bed footprint treated as a proxy for it — which is why the modular and minimal options score better on this page than on our general comparison. We read the current listings and the recurring reports; heat and flattening are the two complaints that dominate this whole category. We have not slept on these; the method is on how we pick.

When night sweats are worth mentioning

Feeling hot and sweating more at night is a normal part of pregnancy and of the early postpartum weeks. Night sweats with a fever, with shivering, with pain, or with feeling generally unwell are different, and worth contacting your midwife or OB about rather than treating as a bedding problem. The same goes for sweats severe enough to be soaking through bedding repeatedly.

If the heat is mostly keeping you awake rather than waking you, see third-trimester insomnia, which covers the whole picture. And for the general shape question, our main pillow comparison is the place to start.
