Struggling to fall asleep at night? If you find yourself in a battle with the thermostat at night, fluctuating between too hot and too cold, you're not alone.
Both your body and room temperature can play a crucial role in the quality of sleep you get, and we've done the research to show you how to find the right balance. 
“Over the last 40 years we gradually increased the temperature of our interior by over 10°F or 6°C” 
Could these rising temperatures be the cause of an increase in number of insomnia and other sleep disorder patients?
We’ll get to that in a minute.
First, let's see exactly what would be the ideal room condition for quality sleep.
|Adults||60-72 degrees||15-22 degrees|
|Elderly||66-70 degrees||19-21 degrees|
|Babies/Toddlers||65-70 degrees||18-21 degrees|
The best sleeping temperature for most adults is 60 to 72 degrees Fahrenheit (15 to 22 degrees Celsius).
The ideal temperature for elderly people is around 66 to 70°F (19-21°C). It is also vital to = keep the living room and bedroom temperature consistent with each other.
The perfect temperature for baby’s room should be slightly cooler around 65 to 70 degrees Fahrenheit (18 to 21 degrees Celsius).
A lot will depend on your personal preferences. Some people naturally sleep hot and others sleep cold. It’s perfectly normal to go below or above these recommended numbers to what makes you feel most comfortable.
Temperature fluctuations during the day and night
Our body temp can fluctuate by 2-3 degrees during 24 hours and is regulated by our circadian rhythm (internal body clock). 
Our thermoregulation changes as we age and we lose some of our ability to control it, but we can definitely change our environment and set a comfortable air temperature for a good night’s sleep.
Experts confirm that the ambient temperature and how you feel will affect the quality of your snooze.
Our bodies have internal thermostats, and when we go to bed, our brain sets this temperature to a few degrees lower than usual, says Dr. H. Craig Heller, Ph.D., a professor at Stanford University.
A slight drop in core temp will make you fall asleep faster, but if it’s too hot or too cold, our bodies might struggle, causing insomnia.
Different mattress types and materials have different thermal properties.
In 2020, there are several dozen brands that promote specialized cooling mattresses that will make even the hottest sleepers feel cool.
Sleeping in a cooler room has many potential health benefits, not just for insomniacs.
It also affects the quality of REM (rapid eye movement), the stage of sleep where you dream, process learning and restore your body.
Hot environments can cause you to spend less time in deep sleep, which can result in sleepiness during the day due to a lower overall quality of sleep.
In the summertime, it’s essential to prepare during the day so you can avoid using air conditioning right before sleep.
Here are some tips to help you cool down your room and yourself during sleep:
During winter, especially in northern states where it gets really cold, it’s recommended to keep the room slightly warmer to accommodate night time drops in temperature.
Some people find it really hard to fall asleep during winter, so here are a few tips:
We hope that this article helped you find the best temperature for sleep for your particular needs or your loved ones.
As you can see, it’s not rocket science but not many of us knew this before doing some research.
