Best Cooling Pillows for Perimenopause Night Sweats
Compare the best cooling pillows for perimenopause night sweats. Gel-infused, water-cooled and phase-change options reviewed by fill type, firmness and care.
How Night Sweats Affect Sleep and Why Your Pillow Matters
Night sweats during perimenopause are driven by falling oestrogen levels that disrupt your body's thermoregulation. Your brain reads a slight drop in oestrogen as a temperature emergency and triggers a flush of heat to the skin surface. The result is damp bedding, a flushed face, and a pillow that has absorbed heat and moisture and now radiates it back at you. A standard memory foam pillow is particularly bad here because it traps heat. Upgrading to a pillow designed to dissipate heat actively rather than passively can meaningfully reduce how many times you wake up during the night. The difference between a heat-trapping foam pillow and a well-designed cooling pillow can be several degrees at the surface, which is enough to interrupt the sweat-wake cycle for many women.
Gel-Infused Pillows
Gel-infused memory foam is the most common cooling pillow category and also the most variable in quality. The gel is either swirled through the foam or applied as a top layer. A swirl-through gel construction tends to perform better over time because the surface layer approach often loses its cooling effect after a few months as the gel disperses heat into the foam beneath it. Look for gel-infused pillows that also have ventilation channels cut into the foam, which allows airflow. Brands like Purple (with their grid technology) and Tempur-Pedic (ProHi + Cooling) use hybrid approaches that combine gel with open-cell foam structures. These are effective for mild to moderate night sweats. They do not actively cool; they absorb and redirect heat, which works well enough if your sweats are moderate rather than soaking.
Water-Cooled Pillows
Water-cooled pillows, such as the Chillow and the Beckham Hotel Collection water insert designs, use a reservoir of water inside or beneath the pillow to draw heat away from your head and neck continuously. They genuinely cool rather than simply absorbing heat, making them a better option for women with severe night sweats. The main trade-offs are weight (water is heavy), occasional leaking if the seal degrades, and the need to occasionally refill or readjust the water level. The Moona is a more advanced version: a smart temperature-regulating pad that connects to a water-circulating unit on your bedside table and can actively cool or warm throughout the night based on a schedule. It is more expensive but is one of the few options that actively manages temperature rather than passively coping with it.
Phase-Change Material Pillows
Phase-change materials (PCM) are substances engineered to absorb large amounts of heat energy when they change from solid to liquid at a specific temperature, typically around 28 degrees Celsius for sleep applications. They feel cool to the touch and stay cool longer than gel alone because they are absorbing latent heat through the phase transition. Pillows using PCM in their cover or fill include the Casper Snow Pillow and several Purple options. PCM covers can also be bought separately and fitted over your existing pillow if you do not want to replace it. The limitation of PCM is that once the material has fully absorbed heat, it stops cooling until it resets, which can take an hour or more. For brief hot flash episodes, PCM works excellently. For prolonged high-sweat nights, it may not last the whole night.
Fill Types: Shredded Foam, Latex and Buckwheat
Fill material determines both the feel and the baseline breathability of a pillow. Shredded memory foam offers more airflow than solid foam blocks and allows you to adjust loft by removing or adding fill. Brands like Coop Home Goods use shredded foam with a cooling cover and are well reviewed for perimenopause use. Latex, particularly Dunlop latex, is naturally more breathable than memory foam and has antimicrobial properties that help with hygiene during sweaty nights. It has a more responsive, springy feel than foam. Buckwheat hull pillows are the most breathable fill available: the hulls leave large air gaps between them that allow heat to escape quickly. They are firm, adjustable, noisy when you move, and not to everyone's taste, but they are genuinely the coolest-running natural fill. Avoid polyester or down fill if night sweats are a significant problem: both trap moisture and heat.
Firmness and Neck Support
Cooling properties are irrelevant if a pillow does not support your neck properly and leaves you with pain. Side sleepers need a higher loft (thicker) pillow to fill the gap between shoulder and ear. Back sleepers need medium loft with some contouring. Stomach sleepers need low loft. Adjustable-fill pillows are the most versatile because you can remove material to dial in the exact height. For women who wake with neck stiffness during perimenopause, a cervical contour pillow with a cooling cover can address both problems at once. The Elviros Cervical Memory Foam Pillow is one option that combines ergonomic contouring with a cooling gel layer. Always check the return policy before buying: cooling performance and neck support are both highly individual, and what works for one person may not work for another.
Care and Washing
A pillow that absorbs night sweat needs regular cleaning. Most cooling pillow covers are machine washable, but the inserts often are not. Check care labels carefully before buying. Shredded foam inserts can usually be spot cleaned but not machine washed. Latex cannot go in a washing machine. Buckwheat pillows require you to remove the hulls before washing the cover. PCM covers can usually be machine washed but should not go in a hot dryer as heat can degrade the phase-change material. For hygiene during perimenopause, a good approach is to buy two pillow covers and rotate them weekly, washing at 60 degrees if the fabric tolerates it. A waterproof pillow protector underneath your cooling pillowcase adds an extra barrier and extends the life of the pillow itself.
