How to Stay Cool at Night (and Reduce Night Sweats)
If you often wake up hot, uncomfortable or kicking off the covers, you are not alone. Sleeping too warm is one of the most common reasons for disrupted rest, and night sweats can make it even harder to settle back to sleep.
While there can be different causes behind overheating at night, your sleep environment often plays a bigger role than expected. The temperature of the room, the layers on your bed and the fabrics closest to your skin can all either help your body cool itself naturally or quietly work against it.
Here are some simple ways to stay cool at night and reduce night sweats, without turning your whole bedtime routine upside down.
Why do you get too hot at night?
Your body temperature naturally rises and falls throughout the night as part of your sleep cycle. To fall asleep comfortably, your body needs to cool itself gradually. If the room is too warm or your bedding traps heat, that process becomes more difficult.
Night sweats and overheating can be made worse by:
- a bedroom that holds warmth
- heavy or synthetic bedding
- hormonal changes, including perimenopause
- stress, alcohol or caffeine late in the evening
- fabrics that trap moisture close to the skin
Even when the cause is not entirely environmental, making your bed cooler and more breathable can still make a noticeable difference.
Keep the bedroom cooler, not colder
The goal is not to make the room feel cold. It is to create a sleep environment that feels fresh, calm and easy to settle into.
- Open a window before bed to let heat escape
- Use a fan to keep air moving gently through the room
- Keep curtains or blinds closed during the day if the room overheats in sunlight
- Avoid running the bedroom too warm in the evening
These small shifts often help more than people expect, especially when combined with lighter bedding.
Rethink the layers on your bed
If you regularly wake too warm, the answer is not always removing everything. Often, it is about layering more thoughtfully.
One very thick duvet can trap heat and leave you with no flexibility. Lighter, more breathable layers are usually easier to adjust through the night.
A more balanced setup might include:
- a breathable mattress protector
- lightweight sheets that allow airflow
- a duvet that does not feel overly heavy
- a separate throw or blanket you can add or remove easily
This helps your bed respond better to temperature changes instead of locking you into one level of warmth.
Choose sleepwear that breathes
What you wear in bed can affect your temperature just as much as your duvet.
Tight, synthetic fabrics tend to hold heat and moisture close to the body. Lighter sleepwear made from breathable natural fibres usually feels more comfortable and allows your skin to cool more easily.
If you tend to wake up clammy, this is one of the easiest things to experiment with first.
Pay attention to the fabric closest to your skin
Sheets and pillowcases sit closest to the body, so they influence how the bed feels within minutes of getting in.
Breathable materials such as bamboo bedding and linen bedding can help create a lighter, cooler sleep surface. If you often feel too warm around the head and neck, silk pillowcases can also feel noticeably cooler and smoother than heavier fabrics.
The aim here is not to turn this post into a shopping list, but to recognise that the texture and breathability of your bedding can either calm the bed down or make it feel stuffier than it needs to.
Be mindful of evening habits
If your body is already running warm, certain evening habits can make overheating more likely.
- Alcohol can make temperature regulation more difficult
- Caffeine late in the day may leave the body feeling more activated
- A very hot bath or shower just before bed can leave you feeling warmer for longer
- Heavy meals late at night can also increase warmth and discomfort
You do not need a perfect routine. But if night sweats are becoming regular, it can help to look beyond the bedding alone.
Keep bedding fresh and breathable
Fresh bedding often feels cooler simply because the fibres are cleaner, lighter and less weighed down by product residue or trapped moisture.
- Wash sheets and pillowcases regularly
- Avoid overusing fabric softener, which can coat fibres and reduce breathability
- Air out your duvet and mattress when possible
- Store spare bedding in breathable bags rather than sealed plastic
These are small maintenance habits, but they help preserve the qualities that make bedding feel cooler in the first place.
When to look more closely at your bedding
If you have already cooled the room, adjusted your layers and changed your evening routine, but still feel consistently too warm in bed, your bedding may be the next place to look.
That is where material choice matters more. Some fabrics feel naturally airy and moisture-friendly, while others trap warmth and humidity. Rather than covering that fully here, we have broken it down in more detail in our guide to the best bedding for hot sleepers.
A cooler night starts with small changes
You do not need to change everything at once to sleep more comfortably. Often, the best results come from a few thoughtful adjustments: a cooler room, lighter layers, breathable sleepwear and fabrics that allow the bed to feel fresher through the night.
If overheating is affecting your rest, start simple. The goal is not to make your bed cold. It is to make it feel balanced enough for your body to settle properly into sleep.
