During the day, the human body’s temperature can fluctuate several degrees while regulating our internal body temperature. While we are young, our bodies are able to regulate temperature much easier. However, as we age, our ability to regulate our internal temperature starts to become less powerful, which can make it difficult to find a comfortable temperature, especially when we’re trying to sleep.

What is the best temperature?

Everyone has their own opinion on what the best temperature is for sleep. Some think that a balmy 75 is ideal, while that may feel like a sauna to others. Many others think that a crisp 68 is perfect, while others might feel that they’re sleeping in a freezer.

However, ice lovers have a point: sleeping in a cooler temperature can help us fall asleep faster and get more quality rest. In fact, as nighttime approaches, our body temperature will start to drop slightly, which tips off the rest of our body into knowing that it’s time for rest. Aiding your body in this response by dropping the temperature in your home at night can help your body and mind prepare for sleep.

In regards to those who prefer warm rooms, some unintended consequences can come with this that you may not even realize can be attributed to the temperature of your room. A too-hot room can cause some discomfort, especially to those who aren’t used to it, which can lead to restlessness and an inability to fall asleep, as well as a higher chance of disrupted sleep in general due to the disruption in our natural thermoregulation.

What are some benefits of sleeping in a cool room?

Since sleeping in a cold room is already helpful for thermoregulation, you’re already on the right track! However, there are some added bonuses to sleeping in a chilly room.

  • You can fall asleep faster. Since you’re aligning your surroundings with your body’s natural clock and cooling down your room with yourself, you can stand to fall asleep faster than you would in a warm room where you’re body might be fighting with the outside temperature to get your internal temperature down to your sleeping temperature.

  • Better quality of sleep. When a room is too warm, oftentimes sleep is interrupted by waking up drenched in sweat. It’s happened to the best of us. With a cooler room, you stand to get some better sleep with fewer temperature-related interruptions.

  • Boosts melatonin production. Since a cooler room is in line with your own drop in temperature which in turn stimulates melatonin production, sleeping in a cold room helps boost that production. This not only helps you fall asleep and stay asleep, but melatonin is crucial in helping with anti-aging. Beauty sleep is a real thing.

  • Better mood. With better sleep comes a better mood! In addition to the benefits of good rest, melatonin also boosts the production of serotonin which is the chemical that makes you feel happy. Likewise, this is also great at helping reduce stress as well.

What temperature do you recommend?

According to, there are optimal sleep temperatures that vary depending on the stage of life that you’re in.

  • Adults/elderly: 60-67 degrees

  • Babies/toddlers: 65-70

The bottom line

Although there is science behind why cooler rooms are better to sleep in, the sleeping temperature ultimately comes down to personal preference! Some of us like to be bundled up in blankets in a cold room while others prefer the warm embrace of the heater at night. It’s important to experiment and find a happy medium that everyone is happy with.
