Sleep is critical for one's overall health - I know it, you know it - studies have proved it. However, did you know that the place you sleep and the environment plays a role in defining your sleep quality?
According to studies, and that too a lot of them, sleeping in a cold room is better for your health than sleeping in a warm room. Though sleeping in a 'cold room' may not sound like a healthy choice, health experts point out that it helps facilitate sleepiness and help the body lose weight in the process .
Benefits Of Sleeping In A Cold Room
There are a ton of benefits that come from sleeping in colder temperatures. It can help reduce the risk of metabolic illness to improve the quality of sleep . Also note that sleep usually begins when our body temperature drops, so a colder room can encourage us to fall asleep faster .

Improves sleep quality: A cooler room can help regulate your body temperature throughout the night, thereby improving your sleep quality . As your body cools down naturally, you slip into a deeper sleep, allowing you to wake up feeling refreshed and well-rested .
Improves metabolism: The human body has different types of fat, which are generally identified by different colours . While white fat is unhealthy fat and is often associated with diseases like type 2 diabetes, brown fat help improves insulin sensitivity and regulate the temperature in your body .
And when you sleep in a cold room, your body will naturally develop more brown fat which will burn to keep you warm, boosting your metabolism naturally .
Benefits Of Sleeping In A Cold Room
Reduces the risk of certain diseases: Studies have shown that sleeping in a room that's consistently 22°C helps you boost up your metabolism, which in turn can help avoid the risk of certain diseases such as diabetes . It has also been pointed out that producing brown fat can help protect people from the rising dangers of obesity .
Prevents insomnia: Studies show that people who suffer from insomnia tend to have a warmer core body temperature before falling asleep. So by being a cooler room, your body will feel eased and calm, thereby signalling your brain that it is time for bed .
Boosts melatonin levels: Your body naturally starts to produce more melatonin as you cool down as the environment you are in effect your circadian rhythm and help you naturally produce more melatonin . This also promotes the production of serotonin - known as the feel-good neurotransmitter .
Reduces stress: Sleeping in a cold room can help reduce your stress levels and improve your mood . It is during your deepest sleep state that your brain, decluttering your mind and sleeping in a cold room can help ease this process and also the production of melatonin as well as serotonin (which is produced along with melatonin) plays an important role here.
How Does Hot Temperature Affect Your Sleep?
The temperature in the space where you sleep and your level of comfort in the space affects how well and how long you snooze. When you go to sleep, your set point for body temperature (the temperature your brain is trying to achieve) goes down. And if the room is too hot or too cold, your body will find it difficult to match the set point . So, if you are in a room that is cool, it is easier for the body to reach the set point and hence makes it easier to sleep .
However, if the room is too cold or too hot, it is more likely that you will wake up as the comfort level of your bedroom temperature also especially affects the quality of REM (rapid eye movement) sleep .
What Is The Best Temperature For Sleeping?
A specific temperature for everyone is not really an applicable option. Experts in the field assert that what is comfortable for one person isn't for another. However, a close-to-specific recommendation would be to keep the room between 19°C to 22°C . Also, it is always best to set the temperature at the sleeper's comfortable level .
How Many Hours Of Sleep Do You Need?

Now that summer is here and most of us wake up sweating, it is indeed important that you bring down the temperature in the room.
