Sleep routines
Home from a cold, wet day outdoors: the NHS 18°C line, and what its sleep page says about a room that's too hot or cold
The NHS says to keep a bedroom at least 18°C in winter and its sleep page says being too hot or cold makes sleep harder. A short evening plan for after a wet day outdoors.
Our research draws on the sources listed below. Lumuwala shares ownership with stores we may discuss, including Calm Eden. About our commercial relationships.
In this guide
An afternoon standing outside at a race meeting, a match or a fair can leave you cold and damp, and the instinct is to turn the heating up. We read the NHS’s keep warm, keep well page and its sleep page on 3 November 2026 and kept to what they say. Lumuwala and Calm Eden share an owner.
What the NHS pages say
- Heat to what is comfortable. The keep-warm page says to heat your home to a temperature that is comfortable for you and, if you can, to at least 18°C in the rooms you regularly use, “such as your living room and bedroom”. It adds that this is particularly important with a health condition, and that it is best to keep bedroom windows closed at night.
- Too hot or too cold. The sleep page says “noise, light, being too hot or cold, or an uncomfortable bed can make it harder to sleep”.
- Regular times. Go to bed and get up at around the same time each day, and give yourself time to relax before bed.
- Drinks. Do not drink alcohol, tea or coffee at least 6 hours before bed. A warm milky drink or herbal tea is the suggested alternative.
An evening plan (our arrangement, not the NHS’s)
| When | What to do | Basis |
|---|---|---|
| As you walk in | Take off wet outer layers and put them where they can dry, away from the bedroom | Our reading; see our guide to drying coats and umbrellas away from the bedroom |
| Early evening | Bring the rooms you use to a comfortable level, 18°C or more if you can, then stop | NHS: comfortable, ideally 18°C or more; too hot or cold makes sleep harder |
| 6+ hours before bed | Last alcohol, tea or coffee | NHS sleep page |
| Before bed | A warm milky drink or herbal tea | NHS sleep page |
| Bedtime | Your usual time, windows closed | NHS: same times each day; windows closed |
What the pages do not say
Neither page gives an upper bedroom temperature, and neither says anything about wet clothes, hot water bottles or how long it takes to warm up after being out. We have not filled those gaps. If you feel unwell, or very cold for a long time, use NHS guidance or speak to a doctor.
Where the umbrella fits
A compact umbrella that dries on a hook by the door keeps the bedroom out of it. Calm Eden’s Royal Ascot and Cheltenham umbrella rules cover the days when you carry one on a long outdoor day. The Haven Umbrella folds to 40 cm (15.75 in), weighs about 390 g and opens to about 105 cm, with a swivel carabiner handle that clips to a bag; the figures are the maker’s. It has an SPF 50+ canopy that blocks 99.99% of UV, a lifetime warranty and a 30 Day Money Back Guarantee that accepts opened or used umbrellas, with free returns. Every order includes a Haven Cover and the Wellness Journal (digital); Buy 2 Get 1 Free adds the UV Charm and the Rain Poncho, and Buy 3 Get 2 Free also adds the Haven SPF 50+ Silk Square Scarf.

Common questions
What room temperature does the NHS suggest in winter?
Its keep-warm page says to heat your home to a temperature that is comfortable for you and, if you can, to at least 18°C in rooms you regularly use, such as the living room and bedroom, and that it is best to keep bedroom windows closed at night.
Does the NHS say a cold bedroom is good for sleep?
No. Its sleep page says noise, light, being too hot or cold, or an uncomfortable bed can make it harder to sleep. It gives no single sleeping temperature.
When should I stop caffeine and alcohol before bed?
The sleep page recommends not drinking alcohol, tea or coffee at least 6 hours before bed, and suggests a warm milky drink or herbal tea instead.
Is this medical advice?
No. It repeats what two NHS pages say and adds our own planning notes, which are marked. If you feel unwell after being out in the cold, use NHS guidance or call your doctor.
