What Is the Best Sleeping Temperature?

Ever wake up groggy, sweaty, or tangled in blankets after tossing and turning all night? The culprit might not be your mattress or your bedtime routine—it could be your bedroom temperature. Getting a good night's sleep at the ideal sleeping temperature is essential for overall health and well-being, as inadequate conditions can lead to poor sleep.

While it’s easy to overlook, the climate of your sleep space plays a major role in how well you rest. Below, we’ll break down the ideal sleep temperature backed by science, explore how your body reacts to heat and cold at night, and share expert tips to create the perfect sleep sanctuary.

Whether you run hot, cold, or somewhere in between, we’ve got you covered with smart solutions like the Chilipad to help you find your perfect sleep zone.

The Optimal Sleep Temperature

Research suggests that the ideal temperature for sleep typically falls between 60°F to 67°F (15°C to 19°C) [1]. This range aligns with the body's natural drop in core temperature, which is important for initiating sleep. A cooler setting helps kickstart this process, making it easier to drift off quickly and slip into more rejuvenating sleep cycles.

Why Bedroom Sleep Temperature Matters?

Here’s why dialing in the ideal sleep temperature isn’t just a comfort thing—it plays a major role in how well you rest:

Core Body Temperature Regulation

As bedtime approaches, your core body temperature starts to dip—a built-in cue that it’s time to wind down. Keeping your room cool works with this natural rhythm, helping you drift off more easily. During sleep, your body temperature can drop by 1 to 2 degrees Fahrenheit, and a cooler sleep environment helps that transition happen smoothly.

Quality of Sleep

Studies indicate that individuals who sleep in cooler environments tend to experience fewer awakenings and longer periods of deep sleep at night. A drop in body temp can also enhance melatonin production, a hormone that regulates sleep [2].

Research has shown that temperatures above 75°F can throw off your nightly rhythm, causing increased wakefulness, more tossing, turning, and less restorative rest overall.

Comfort

Getting too warm at night can cause restlessness and frequent wake-ups. A cooler room helps you stay comfortable and undisturbed. In fact, a study published in The Journal of Sleep found that people in cooler environments reported better overall quality of sleep than those in warmer settings. [3].

How Does Temperature Affect Sleep?

Temperature has a big impact on how well and how long you rest. Here’s how it can make or break your rest:

Sleeping Too Hot

As you wind down for the night, your body naturally cools down to get ready for rest. That’s why burrowing under the covers feels so relaxing. But if your room is too hot or stuffy, it can have the opposite effect. Instead of drifting off, you’re more likely to toss, turn, and wake up feeling groggy.

Too much heat is a known Deep Sleep killer. A hot room can push your internal temp up, making it harder for you to enter deep, refreshing rest.

Pro tip: If your bedroom is above 70°F, it’s time to turn down the thermostat for better shut-eye.

Sleeping Too Cold

Chilly nights might feel refreshing, but sleeping in a room that’s too cold can come with its own set of problems. While it may not throw your sleep cycles out of whack like heat does, it can still take a toll on your body.

Did You Know: A 2018 study found that cooler temps don’t disrupt your sleep cycle nearly as much as excessive heat does.

When you're too cold, your system goes into overdrive to warm you up—tightening blood vessels, making breathing more shallow, and putting extra stress on your cardiovascular system. Not exactly the recipe for restful sleep. But that’s where the

Chilipad steps in. It gives you full control over your bed’s climate—cool it down, warm it up, or land somewhere in the sweet spot, so your body doesn’t have to fight to get comfortable. Effortless, all-night comfort at the tap of a button.

Quick Tip: If your bedroom temperature dips below 60°F, it’s probably time to bump up the temp a bit for a healthier, more comfortable night’s rest.

Here are a few more ways temperature can make or break your sleep game:

• Sleep Onset: A cooler environment can help you fall asleep faster by making it easier for your body to kickstart its natural cooling process. On the flip side, a warm room can interfere with that process, delaying sleep and making it harder to nod off.
• Sleep Stages: Different stages of sleep require different temperatures. For instance, during REM (Rapid Eye Movement) sleep, the body’s temperature regulation is less effective, making it more susceptible to external temperature changes. A cooler environment can help maintain a stable temperature during this critical sleep stage, promoting better sleep quality.
• Sleep Disruptions: High temperatures can lead to increased awakenings throughout the night. When you sleep hot, it can trigger wakefulness, causing you to toss and turn. This disruption can prevent you from reaching the deeper stages of sleep, which are essential for restorative rest.

The Science Behind Sleep Temperature

Understanding the science behind sleep temperature can help you appreciate its importance. The body’s circadian rhythm, which regulates sleep-wake cycles, is closely linked to temperature changes. As night falls, the body cools, preparing for sleep. This cooling process is influenced by several factors, including:

Metabolism

Your metabolic rate decreases during sleep, which contributes to the drop in body temperature. A cooler environment can enhance this natural process, improving the body's ability to allow for a smoother transition into sleep.

Thermoregulation

The hypothalamus, a part of the brain responsible for regulating body temperature, plays a crucial role. It responds to changes in the environment and adjusts the body’s temperature accordingly. When the room is too hot, the hypothalamus may struggle to cool the body down, leading to discomfort and disrupted sleep.

Sleep Stages

Different stages of sleep, including slow wave sleep, require different temperatures. For instance, during REM (Rapid Eye Movement) sleep, the body’s temperature regulation is less effective, making it more susceptible to external temperature changes.

A cooler environment can help maintain a stable temperature during this critical sleep stage.

Sleep Expert Recommendations

To help you stay comfortably cool (or warm) through the night, here’s what sleep experts recommend for dialing in the ideal sleep temperature:

Bedding and Sleepwear

Choose breathable materials for your bedding and sleepwear to create a comfortable sleep environment. Cotton and bamboo fabrics are top picks for a cooler night—they’re breathable and wick away moisture to help regulate your body temp.

Steer clear of synthetics, which tend to trap heat and sweat, making things stuffy and uncomfortable.

Cooling Products

Consider using cooling mattresses, pillows, and mattress protectors. Products like the Chilipad Dock Pro and Chilipad Cube Bed Cooling Systems are designed to lower your body temperature, providing a comfortable sleep experience.

These products use advanced technology to actively circulate water and maintain optimal sleep temperatures throughout the night.

Bedroom Environment

Keep your bedroom well-ventilated. Use fans or air conditioning to achieve the desired temperature, and avoid heavy blankets that can trap heat. A well-ventilated room allows for better airflow, which can help regulate temperature and improve sleep quality.

Tips for Better Sleep Temperature & Environment

Pre-Sleep Routine

Establish a pre-sleep routine that includes lowering the thermostat. This sends signals to your brain that it’s time to wind down. Consider incorporating relaxation techniques such as reading, meditation, or gentle stretching to prepare your body for sleep.

Personal Preferences While the general recommendation is for cooler temperatures, individual preferences may vary. Experiment with different settings to find what feels most comfortable for you. Some people may prefer slightly warmer or cooler conditions, so it’s essential to listen to your body.

Humidity Levels

In addition to temperature, humidity can also impact sleep quality. Ideally, the humidity level in your bedroom should be between 40% and 60%. High humidity can make a room feel warmer, while low humidity can lead to dry skin and respiratory discomfort. Using a humidifier or dehumidifier can help maintain optimal humidity levels.

Limit Electronics

Electronic devices emit heat, which can raise the temperature of your sleeping environment. Try to limit the use of electronics in the bedroom, especially before bedtime, and consider relaxing activities like a warm bath . Additionally, the blue light is emitted.

Final Thought

Sleep isn’t just about how long you’re in bed—it’s about how well your body can recharge while you’re there. And temperature plays a bigger role than most people realize. From supporting your natural circadian rhythm to helping you stay in deeper stages of rest, getting your sleep environment just right can make all the difference.

The sweet spot? Somewhere between 60°F and 67°F for most people. But your perfect temperature is personal—and customizable.
