Have you ever noticed that you tend to sleep better when the room is a little cooler? You’re not alone! Many people find that a cooler environment helps them drift off faster and stay asleep longer. But why is that? It turns out there’s real science behind how temperature impacts your sleep quality. We’ll explore how sleeping in the cold can lead to deeper, more restorative sleep, share tips on creating a cool sleep environment and help you decide if cold sleeping conditions are right for you.
The Science Behind Temperature and Sleep
The relationship between temperature and sleep is more complex and fascinating than you might think. Our bodies have an intricate system for regulating temperature throughout the day, which is closely tied to our sleep-wake cycle. At the center of this relationship is the circadian rhythm, or our body’s internal clock. This clock doesn’t just tell us when to feel sleepy or alert — it also manages our core body temperature. As evening rolls around, our body naturally cools down, reaching its lowest point in the early morning hours.
When we fall asleep, our body temperature decreases by about one to two degrees Fahrenheit. While that might sound like a small change, it’s key for getting into those deep, restful stages of sleep that help us feel energized in the morning. During rapid eye movement (REM) sleep, which is vital for mental and emotional restoration, our ability to regulate body temperature temporarily shuts off. This is why sleeping in a cooler environment is so important for quality REM sleep.
Temperature also influences the production of melatonin, often called the “sleep hormone.” Cooler temperatures can help stimulate melatonin production, making it easier to fall asleep and stay asleep throughout the night. This is one reason why many people find they sleep better in a cool room.
Ideal Temperature for a Good Night’s Sleep
According to the Sleep Foundation, the best temperature for sleep is between 65 and 68°F. Of course, everyone’s comfort level is a bit different, so you might need to tweak the temperature based on your preferences. But the general idea is to keep things cool without being chilly. If your room is too hot, it can leave you tossing and turning, as your body struggles to cool down. On the flip side, if it’s too cold, you may find yourself waking up to grab another blanket.

How to Create a Cooler Sleep Environment
You don’t have to blast the AC or wait for a cold snap to create the perfect cool sleep space. A few simple tweaks can make all the difference in helping you stay comfy and drift off into a peaceful slumber.
Adjusting Your Bedding
One of the easiest ways to cool down your sleep space is by swapping out heavy, heat-trapping bedding for something lighter and more breathable. When choosing quality bedding materials, it’s common to compare cotton vs. linen. Both are excellent options for staying cool. Cotton is soft and lightweight and great for wicking away moisture, while linen offers a more textured feel, is highly breathable and naturally absorbs heat to keep you cool throughout the night. If you tend to sleep hot, you might also consider investing in a cooling mattress or mattress topper designed to regulate temperature and provide comfort all night long.
Find the Perfect MattressUse Fans or Air Conditioning
Fans are a budget-friendly way to keep the air flowing in your room, especially during those warm summer nights. Try placing one near a window to draw in some fresh, cool air. If you prefer air conditioning, set it to a comfortable, steady temperature, but don’t make it too chilly. You want to feel cozy, not frozen!
Natural Ventilation
If the weather’s nice, why not crack open a window to let in some cool, fresh air? Not only does this help regulate the room’s temperature, but it can also improve air quality, which is a win for better sleep. You can even add lightweight curtains to control the breeze while keeping the room feeling calm and relaxed.
Who Should Avoid Sleeping in Cold Conditions?
While sleeping in a cool room can work wonders for most people, it’s not the best option for everyone. Some individuals might find that colder environments disrupt their sleep or create discomfort.
People with Certain Health Conditions
If you suffer from conditions like arthritis, Raynaud’s disease or respiratory issues, sleeping in a cold room could aggravate symptoms. For example, cold temperatures can cause joint stiffness or increase sensitivity to cold extremities for people with circulatory issues. In these cases, keeping the room slightly warmer or using extra blankets may provide relief and comfort without sacrificing sleep quality.
Infants
Little ones, especially babies, can have trouble regulating their body temperature since their bodies are smaller and still developing. For them, sleeping in a room that’s too cold could be uncomfortable or even unsafe. The Sleep Foundation suggests they should sleep in a room between 68°F to 72°F. Also, dressing them in breathable layers and using a light blanket or sleep sack can help keep them at a safe, comfortable temperature throughout the night.
Elderly People
Older adults may be more sensitive to cold and could experience discomfort or chills in a room that feels fine to younger people. Additionally, sleeping in a room that’s too cold could make them more vulnerable to respiratory issues or even affect circulation. According to WebMD, the best sleep temperature for older adults is between 70°F to 74°F.
