Why body pillows feel hot

A head pillow touches your face and neck. A body pillow touches your chest, arms, belly and the insides of your legs, often for hours. That is a lot of skin contact with a material that holds heat, and the space between you and the pillow has little airflow. Anyone who already sleeps warm notices it fast.

Your body is also trying to cool down at night. The Sleep Foundation says core temperature drops before and during sleep, and that higher core temperature is linked to less deep, restorative sleep. Anything that holds heat against you works against that.

Fills that breathe, and the one that does not

These notes come from the Sleep Foundation's body pillow guide, which also mentions charcoal-infused foam and cooling gel as options some makers use to reduce heat retention. Its cooling pillow guide adds that gel, copper and graphite are conductive materials that dissipate heat and that phase-change materials in covers absorb and release heat.

The cover does half the work

The Sleep Foundation says covers made of breathable or moisture-wicking fabrics help hot sleepers. In its cooling pillow guide, it notes cotton is soft, breathable and wicks moisture, while bamboo-derived rayon is lighter and more absorbent than cotton, which suits sweaty sleepers.

• Look for a removable, zippered cover so you can wash it often.
• A cool-touch phase-change cover feels best when you first lie down.
• A body pillow cover in a cooler fabric can upgrade a pillow you already own. See body pillow covers.

Size and shape when heat is the issue

The Sleep Foundation says most body pillows are 48 to 54 inches long. For a hot sleeper, a straight pillow is often easier than a U shape, because a U surrounds you front and back and leaves nowhere for heat to go. If you want a U for support, choose the most breathable fill and cover you can find. See U-shaped body pillows and body pillows for side sleepers.

Common mistakes

• Buying on the word cooling alone. Check the fill. A solid memory foam core with a cooling cover will still hold heat where you hug it.
• Using a thick fleece or minky cover. Plush, synthetic covers feel cozy in the store and warm at night. Save them for winter.
• Hugging it tight all night. Resting your arm and knee on the pillow, rather than wrapping your whole front around it, leaves more skin exposed to air.
• Washing the cover rarely. Sweat builds up in the fabric and makes it feel clammy. Wash the cover often, following the care label.
• Ignoring the bedding. A heavy comforter over you and the pillow undoes most of what a breathable fill can do. Layer lighter covers you can kick off.

Room tips that help any pillow

The Sleep Foundation suggests a bedroom around 65 degrees Fahrenheit, closing blinds during the day, a fan or air conditioning, managing humidity, and a warm bath 1 to 2 hours before bed so your body cools afterward. A fan aimed across the bed also dries the skin where it touches the pillow.

What to look for when you buy

Questions people ask

What is the coolest body pillow fill?

The Sleep Foundation says fiber, latex and down are typically more breathable than memory foam, and cross-cut foam lets air move more freely.

Do cooling body pillows work?

Breathable fills and covers make a real difference. Cool-touch covers and gel feel cool at first, but a cool room matters most.

Is a U-shaped body pillow too hot?

It can be, because it surrounds you. Hot sleepers often do better with a straight pillow and a breathable cover.

How long should a cooling body pillow be?

The Sleep Foundation says most body pillows are 48 to 54 inches long. Shorter ones suit shorter sleepers; taller people may want the longer end.

How do I wash a cooling body pillow?

The Sleep Foundation says many body pillows have removable, machine-washable covers, while foam is often spot-clean only. Follow the label.
