Night sweats are a heat problem and a moisture problem

Cleveland Clinic describes night sweats as heavy sweating episodes during sleep, much stronger than normal sweating, that can soak clothes and bedding. That gives a pillow two jobs. It has to avoid trapping heat around your head and neck, and it has to cope with being wet without staying clammy all night.

Most cooling pillow marketing focuses on the first job. For night sweats, the second matters just as much.

Build the pillow setup in layers

1. A fill with airflow. The Sleep Foundation says latex is more breathable than synthetic foam, buckwheat hulls create air pockets that prevent heat buildup, and shredded foam runs cooler than solid foam. Solid memory foam can retain heat.
2. A breathable cover. The Sleep Foundation says cotton is breathable and wicks moisture, while bamboo-derived rayon is more absorbent than cotton, which suits hot or sweaty sleepers. Wool also wicks moisture.
3. A pillow protector only if it breathes. A protector keeps sweat out of the fill, but a plastic one traps heat. If you use one, choose a breathable fabric.
4. A spare pillowcase on the nightstand. Swapping a damp case for a dry one takes seconds and avoids getting fully up.
5. A second pillow. Flipping to a pillow that has not been under your head can give you a fresh, cooler surface.

The rest of the bedroom

Cleveland Clinic's home tips for night sweats are practical: use air conditioning or a fan, open windows, sleep in less clothing, use lightweight layered covers you can remove in the night, wear loose cotton or linen pajamas, keep cold water by the bed, and avoid spicy foods and caffeine. The Sleep Foundation recommends a bedroom around 65 degrees Fahrenheit.

For hot flashes, Mayo Clinic suggests dressing in layers, using a fan or air conditioner, lowering the room temperature, sipping a cold drink when a flash starts, and noting that hot and spicy foods, caffeine and alcohol can trigger flashes. It also says slow, deep breathing may help some people with mild hot flashes.

What causes night sweats

The NHS lists the most common causes as menopause hot flushes, anxiety, some medicines such as certain antidepressants, steroids and painkillers, low blood sugar, alcohol or drug use, and hyperhidrosis. It notes that it is normal to sweat at night if your room or bedding is too hot. Cleveland Clinic says night sweats are common in perimenopause and menopause, and also lists infections, an overactive thyroid and other hormone conditions, sleep apnea, and some cancers and their treatments. If you are close to 50 and waking drenched, it says menopause is likely the cause.

Signs it is time to see a doctor

The NHS says to see a GP if night sweats happen regularly and wake you or worry you, or if they come with unexplained weight loss, a very high temperature or feeling hot and shivery, a cough, or diarrhea. If a medicine may be the cause, a doctor may be able to change it. Cleveland Clinic advises seeing a provider if night sweats disrupt your sleep. A cooler pillow can make nights more bearable while you find out why.
