Ideal room humidity and best temperatures for sleeping

Our bodies are very complex structures, and turning all of it off for sleep requires effort. In short, we actually have to work at getting rest, and the key to getting there faster has been the challenge that the sleep industry has worked towards solving ever since their inception.


There are plenty of factors that can help or prevent you from getting good sleep - diet, sleeping issues, psychological state - and each industry tries to solve this problem in their own way. One common solution is simply affecting the temperature of the sleeper when they fall asleep, but this isn’t as easy as you may think.

Best temperature for sleeping in Celcius

The best temperature for sleeping is around 16~18 degrees celsius (60.8~64.4°F). However, 18.5°C ~ 20.5°C is an ideal house temperature range for your room. Everyone's sense is a bit different and you should choose a temperature that makes you most comfortable. Keeping the temperature a bit higher also saves your home's electricity!


This is the normal temperature our circadian rhythm (the 24 hour process or cycle our body physically goes through) in order to get to sleep. But plenty of factors can affect this: our environment, our physical activity before rest, and even the food we eat can all play a role in how easily or how hard it is for us to rest.


Best humidity level for your home and bedroom


Relative humidity (RH) is a standard way to measure humidity. The best way to measure room humidity is with the use of hygrometer. Here is the way to measure relative humidity level in your home.


If there is a natural wind or a breeze in a high humidity climate, even if the temperature is not particularly low, the apparent temperature is often lower than the actual temperature. For example, the mobile device displays a temperature of 8 degrees and the humidity is 81%, but the apparent temperature is actually only 3 degrees. In this case,  you need to stay warm.


There are researches show that 40% ~ 60% humidity is ideal for indoors. However, during winter times, it is usually difficult to keep the air this moist. Most people do keep their room humidity at around 40% - 50% and that's usually the average comfort zone.


According to the US natural sleep foundation, the ideal room humidity level for better sleep is between 30% ~ 50%. This means being in a environment that is too dry, or has too much moisture can impact our the quality of our sleep.

First of all, if the environment is too humid, the moisture within your body will be harder to evaporate. This will make you hot, and stuffy, making it harder for us to sleep comfortably. For those who have allergies, humid environment will also accelerate mold growth. This might make your allergy worse and affect your sleep at night.

Then comes the problem of being too dry. When your skin and breathing system gets too dry, you might get itchy throats or catch a cold. When you feel itchy, sick and irritated, you won't be able to sleep well.

Falling asleep 101

Our body cools down when we begin to drift off to sleep - it’s this process that usually indicates to our systems that it’s time to rest. For people with lower or higher than average body temperatures like athletes or those used to an extreme climate, getting to this point can be difficult.

Sleep aids and products aim to help people reach this point faster - and none of the products are as common and as accessible as the heating blanket. Simple and easy to use, it’s been a common tool for people to use in order to help themselves get to sleep more comfortably.

So what seems to be issue?

Heating and 4D DWF

The primary purpose of heating blankets is to introduce heat - but the earliest models also had trouble getting rid of it, or introducing the right kind of heat. Without a way to control to humidity, the air inside the the blanket became hot and arid, often causing troubles as often as they would clear them.

The primary issue was dry air: the air that comes when the blanket doesn’t have enough breathability. You couldn’t use them for too long as you’d feel stuffy from all the heat, and the heat generated from the blanket would mix with your own body heat in response, finally forcing you to kick off the blanket - which would mean the resulting temperature change would shock your body awake, or straight into a cold the next day.

However, Wellcare’s innovation in heating blankets seeks to change all that. With a design focused on creating the sleeper’s own climate when they are at rest, we’ve developed the 4-Dimensional Dynamic Warmth Flow technology and integrated it with our heating blankets. Efficient at heating, but at the same time allow humidity from outside the blanket allow our products to help you get to sleep far better.

4D DWF technology disperses the heat generated by our blankets through uniquely designed holes, allowing them to give you ideal conditions for sufficient and comfortable sleep.
