Night sweats are one of the most disruptive sleep problems there is — and they are extremely common, particularly in women going through perimenopause and menopause. A good cooling blanket does not stop night sweats but it significantly reduces how much they disrupt your sleep. The key is choosing one that actually works.
What Makes a Cooling Blanket Effective for Night Sweats
Night sweats involve sudden intense heat followed by sweating and chills. An effective cooling blanket needs to do two things: draw heat away from your skin during the episode and wick moisture efficiently so the post-sweat chill is less severe.
Most cheap cooling blankets fail on both counts. They feel cool for a few minutes then trap heat exactly like a regular blanket. When a night sweat hits they make the experience worse not better.
What to Look For
Q-Max of 0.35 or above. This is the standardised measure of contact cooling. Below 0.35 and you are essentially paying for a thin regular blanket. The Stillwell Cloud has a Q-Max of 0.40.
100% nylon cooling fiber. Not polyester, not a blend. Nylon has the highest thermal conductivity of common blanket materials and it maintains that property wash after wash. Polyester marketing claims do not hold up in practice.
Both sides cooling. You move during night sweat episodes. A blanket that is only cool on one side means you regularly land on the wrong side at exactly the wrong moment.
Moisture wicking. The post-sweat phase — where sweat evaporates and you suddenly feel cold — is often as disruptive as the sweat itself. A blanket that wicks moisture away from your skin reduces the severity of this phase.
Lightweight construction. Heavy fill adds to the heat load your body is trying to shed during an episode. Hollow fiber fill allows heat to escape rather than accumulate.
Our Recommendation
The Stillwell Cloud meets all of these criteria — 100% nylon cooling fiber, Q-Max 0.40, cool on both sides, lightweight hollow fiber fill, machine washable. Built specifically for hot sleepers and people dealing with night sweats. See The Cloud →

What a Cooling Blanket Cannot Do
A cooling blanket manages the heat during and after night sweat episodes. It does not address the underlying cause — hormonal changes, medications, stress, or other triggers. If night sweats are significantly affecting your quality of life it is worth speaking to a doctor about the underlying cause alongside optimising your sleep environment.
The Bottom Line
The best cooling blanket for night sweats is one made from nylon cooling fiber with a Q-Max of 0.35 or above, cooling on both sides, with good moisture wicking. Everything else is marketing.
