Whilst this can be a challenge in modern living spaces, if possible, your bedroom should be the room in your home that’s devoted to sleep. It’s the ‘bed’ room and should, ideally, not be the office, games room, gym or cinema, but the place for sleep.
In some languages, the word for ‘bedroom,’ like in German ‘Schlafzimmer,’ and Dutch ‘Slaapkamer’, make this explicit, by calling it the ‘sleep’ room. This makes it clear that the room should be devoted primarily to getting optimal sleep.
Ideally, your bedroom should be a sanctuary from the stresses and strains of the world, a place where you can feel safe and secure, a retreat from daytime life. If you can use your bedroom for sleep and intimacy only then that would be ideal.
However, it’s not just the room temperature that’s important for getting good sleep. The temperature in your direct sleeping environment, i.e. under the duvet, is equally important and should be as close to thermoneutral (approximately 29°C) as possible.
Think of it this way: your body gives out heat in bed, much like a giant hot water bottle, and so you’ll ordinarily heat the space between your sheets just by being in bed.
During the night, the body needs to lose heat and this is done mainly through the head and face since these are the only bits that typically stick out from under the duvet.
A cool bedroom facilitates heat loss from the head and face, leading to better sleep.
If your bedroom is too hot, or you’re too hot under your duvet, it’s more difficult for your body to lose heat and this will cause disturbed sleep.
The same is also true if you’re too cold as this means your body has to work hard to maintain its optimal temperature and, again, this can disturb sleep. So, getting the best temperature for sleep requires the right combination of:
If this means you wear bed socks but have the window open, so be it.
Achieving the right temperature can be additionally complicated by your bed partner as they’ll no doubt need different conditions to you in order to achieve their comfortable sleep temperature.
The general advice is that the bedroom needs to be as dark as possible during the night. But how dark is dark?
If during the night, you can stand at one side of your bedroom and see the opposite wall then your bedroom is much too bright.
Even small amounts of light, for example from your alarm clock, can have an impact on your sleep. You can reduce light in the bedroom by:
Your bedroom should be as quiet as possible. 5 It’s a simple fact that some noise can disturb sleep. The reason for this is that when you sleep, you’re vulnerable and seemingly unaware of your surroundings.
From an evolutionary perspective, being unaware of your surroundings would put you at a disadvantage. For our distant ancestors being fast asleep came with the threat of something big and hairy being able to find and eat you, so we likely evolved to be aware of threats while asleep.
Because we’re deprived of our vision when sleeping, we have to rely on our hearing to give us information about the environment. Each of us wakes up hundreds of times during our sleep to check that we’re still safe and secure.
These arousals are very short, no more than 1-2 seconds, and we’re not aware that we have them. If the brain, via our hearing, doesn’t detect anything of ‘importance’ then we can safely continue to sleep.
Conversely, if we perceive something in the environment that’s not right (for example, an unexpected noise) our ‘primitive’ brain needs to be sure that this isn’t a threat and so we become fully awake to process and rationalise what’s going on.
However, we don’t wake up to each and every noise. It must be a ‘meaningful’ sound i.e. perceived as important or a threat, for it to disturb our sleep.
This means that we can actually get used to sounds that initially seem very disturbing. This usually takes at least a couple of weeks as our brain works out that a particular noise is not a threat and it’s safe for us to ignore it.
The fact that we can adapt to some sounds in time doesn’t help when we’re staying somewhere temporarily. If you’re on holiday, for instance, it’s probably easiest to carry some earplugs.
Of course, if a sound is loud enough, regardless of how meaningful it is, then it’ll wake you up. This is particularly applicable in the latter part of the night when your sleep is naturally lighter and more easily disturbed.
Ideally, your bedroom should be as quiet as possible but this may not be an easy option. If you can’t create a quiet bedroom then you might want to try using other sounds like:
These sounds can distract the brain from more disruptive noises.
It really doesn’t matter what noise you listen to. The most important thing is that your brain doesn’t have to listen to it actively. Remove from the bedroom any sources of noise that are at a level that disturbs your sleep (including your partner!).
The bedroom shouldn’t be stuffy and fresh air is good for sleep. Opening the window lowers the levels of carbon dioxide in the air and that’s been shown to improve the quality of sleep.6
The bed is an important part of life. If you live until the age of 70 you’ll spend approximately 220,000 hours asleep and you’ll probably do the majority of this in a bed.
So in your lifetime, you’ll spend more time in bed than you’ll spend in any other single location. It’s undoubtedly crucial that you have the right bed, taking into consideration your weight, body shape, height and medical status.
It’s unavoidable that you need to invest time and money in choosing and buying a bed. You wouldn’t buy a sofa without sitting on it and you probably wouldn’t buy a car if it was uncomfortable to drive, so don’t be tempted to buy before you try with a bed.
Regardless of what bed manufacturers or retailers tell you about how long a bed should last, you should buy a new bed when you start noticing your old bed. For example:
Consider that each night you sweat a significant amount of moisture and shed a good amount of dead skin into your mattress so, for hygiene reasons alone, it would be sensible to change your bed regularly.
Remember, you can buy the best, most luxurious, most expensive bed on the planet and it will not guarantee you a good night’s sleep.
That’s rather like a bad driver buying an Aston Martin and expecting to be a good driver. If your lifestyle or bedroom environment isn’t conducive to good sleep then having a good bed will make little difference.

Science cannot measure mattress comfort. Essentially, it’s a matter of personal choice. Mattresses do differ in the comfort and support they claim to provide and so the only way to choose one that’s right for you is to go out and lie on as many as possible.
The key to buying a mattress lies in the line of your spine. If a mattress is right for you, your spine should:
You want to make sure that you’re sleeping ‘in’ the bed and not ‘on’ the bed. Too hard a mattress stops both the hips and shoulders sinking down into the mattress but too soft a mattress is unable to provide any resistance to the body’s weight.
So, when looking for a mattress, lie on it for at least 10 minutes and more if possible. You naturally move 40-60 times each night, of which 10-20 are major positional changes.
Testing a mattress for a longer time means you’re more likely to assume more of the positions you’ll take during your night’s sleep. It’s also important to feel what it’s like when you try to roll over. It will:
One other trick for testing the bed is when you’re lying on your back, place your hand between your back and the mattress.
People tend to buy a bed with their eyes rather than with their body. They’re seduced by a stylish bedstead or a fancy headboard rather than understanding that, however beautiful a bed looks, it’s the feel of the bed when you’re lying down that’s of the utmost importance.
The ‘technical specifications’ of a bed provide little helpful data to allow you to judge the comfort of a bed. For example, it’s not as simple as saying more springs equal a better bed.
The price of the bed also has no bearing on the comfort of the bed: more expensive does not necessarily equate to more comfortable. You can find more advice on buying a bed in our article, here.
The pillow is for your head and neck what the mattress is for your body. So it’s essential that the pillow works in conjunction with the mattress to provide the correct support.
Again, the only way of judging if a pillow will be comfortable for you is to actually try it out on a bed in the same way that you would use it at home.
Having too thick or too thin a duvet will affect body temperature loss during the night and can make getting good sleep more difficult.
Thankfully duvets, unlike mattresses and pillows, have a standard, meaningful, classification system: the ‘tog’ rating. So regardless of what the duvet is made of, you know that a particular ‘tog’ is designed to provide a specific level of warmth.
There’s a lot of aspects to designing your bedroom to get the best night’s sleep you can. Much of the work involves making the bedroom as good a place as it can be in order to wind down and rest your senses. We’ve covered:
