Does Warmth Help You Relax?

Short answer: does warmth help you relax? Many people find warmth relaxing, and there is some research on warm baths and sleep, but we haven't found strong proof that warm air on the body relaxes you in a measurable way, and we don't claim it does.

Does warmth help you relax?

• What the research says: a review of studies in Sleep Medicine Reviews linked warm water of about 104 to 109°F (40 to 43°C), taken 1 to 2 hours before bed, with better self-rated sleep quality and about 10 minutes quicker sleep onset on average. The authors said the studies differed widely.^[8] This is about baths and showers, not our devices.
• What we hear: many visitors tell us they find a warm-air session relaxing. That is their experience, not a medical result.
• What else helps: breathing exercises, being active and time for yourself are the NHS's suggestions for stress.^[4][5]
• Be careful with heat if you have diabetes, numb skin, a heart condition, or you're unwell: ask your doctor first (our own caution).

If you'd like to feel it for yourself, your first session is complimentary.

When to see a doctor
