Whether you prefer to sleep in a hot or cold room is a matter of personal preference, but research suggests that sleeping in a cold room may be better for your sleep quality. Sleeping in a cold room can improve sleep quality by stimulating melatonin production, a hormone produced in response to darkness and cold that helps the body fall and stay asleep. A cooler room can also improve the quality of your sleep, making you feel more rested and happier. The ideal temperature for sleep is generally considered to be between 60 and 68 degrees Fahrenheit, but this can vary depending on individual preferences and circumstances.
| Characteristics | Values |
|---|---|
| Ideal room temperature for sleep | 60-68°F (15.6-20°C) |
| Warmer room temperature preference | People over 50, those with anxiety or sleep disorders |
| Cooler room benefits | Faster sleep onset, improved sleep quality, increased melatonin and serotonin production, reduced insomnia, anti-aging effects |
| Warmer room benefits | Comfort, easier to achieve for those prone to feeling cold |
| Risks of very cold rooms | Hypothermia, reduced immune function |

What You'll Learn
A cold room can improve sleep quality
Sleeping in a cold room can improve sleep quality. While personal preferences vary, a cooler environment is generally considered better for sleep. When the room is too warm, it can disrupt sleep by blocking the body's natural signal to slow down and rest.
Sleep professionals recommend a bedroom temperature of 65–68°F (18.3–20°C). However, the ideal temperature for sleeping is between 60–67°F (15.6–19.4°C). At this temperature, the body can release more melatonin, a hormone that helps with sleep and has anti-aging properties.
Keeping your bedroom cooler can help you fall asleep faster and improve your overall sleep quality. It reinforces the body's natural drop in temperature, which signals that it's time to sleep. A cooler room can also promote relaxation and reduce insomnia symptoms. Additionally, a cold room may increase serotonin levels, which can enhance your mood.
However, it's important to note that a room that is too cold can also disrupt sleep. If you feel too cold, you may need to bundle up, which can make you too hot later. Therefore, it's essential to find a comfortable temperature that works for you.

A cold room may stimulate melatonin production
Sleeping in a cold room is better for sleep quality as it stimulates melatonin production. Melatonin is often referred to as the body's "sleep hormone", and it is produced in response to darkness and cold, helping the body fall and stay asleep. As your body prepares for sleep, your body temperature starts to drop. Keeping your room cool may signal to your body that it's time to sleep.
Research suggests that the ideal temperature for sleep is between 60 and 68 degrees Fahrenheit, with some sources specifying an even narrower range of 65 to 68 degrees Fahrenheit. However, it's important to note that individual preferences and circumstances vary, so adjustments may be necessary. For example, people over 50 tend to sleep better in slightly warmer rooms, and infants should sleep in rooms ranging from 65 to 70 degrees Fahrenheit. Additionally, those with underlying health conditions like asthma or COPD should consult a healthcare provider to determine the appropriate temperature for their needs.
While sleeping in a cold room can improve sleep quality, it is important to ensure that the room is not too cold. If the room is too cold, you may need to bundle up, which can make you feel hot later, or you may end up shivering and too uncomfortable to sleep deeply. Therefore, it is recommended to invest in appropriate sleepwear and bedding, such as warm socks or a thick blanket, if you are prone to feeling chilly at night.
Ultimately, the temperature of your bedroom should align with your personal preferences and circumstances. By experimenting with different temperatures and observing how they impact your sleep quality, you can determine the optimal temperature for your unique needs.

A hot room can cause discomfort and restlessness
Secondly, a hot room can make it challenging to regulate your body temperature, leading to restlessness and discomfort. You may find yourself tossing and turning, trying to get comfortable, and wasting energy that could be used for restorative sleep. This can result in poor sleep quality and leave you feeling groggy and foggy the next day.
Additionally, hot sleepers tend to get warm and sweaty at night. They may wake up frequently, feeling the need to adjust their sleeping position or stick a leg out from under the covers to cool down. This interrupts their sleep and can be frustrating and uncomfortable.
Lastly, a warm room can reduce the time spent in REM sleep, impacting the immune system, memory, learning, and bodily recovery. A cooler room, on the other hand, encourages deeper sleep and can boost melatonin production, which improves sleep quality and mood.
While individual preferences vary, most sleep professionals recommend a bedroom temperature of 60 to 68 degrees Fahrenheit for optimal sleep.

A cold room can reduce insomnia symptoms
Sleep professionals recommend a bedroom temperature of 65–68 °Fahrenheit for a good night's sleep. However, individual preferences vary, and older people might prefer a slightly warmer room. For instance, if you're a "hot sleeper", you should lower the temperature in your room and use curtains to block sunlight during the day. On the other hand, "cold sleepers" should consider wearing socks or silk pyjamas to bed or using an extra blanket to warm up.
A cooler room improves sleep quality, and you're more likely to fall asleep faster. Sleeping in a cold room can lower your body's core temperature more quickly, which boosts melatonin—the body's "sleep hormone". A cool bedroom also helps people sleep deeply for longer periods. Keeping your room at a lower temperature may promote relaxation and make it easier to fall asleep. Researchers have found that keeping cool reduces insomnia symptoms and promotes sleep.
Additionally, a cold room may increase your level of serotonin, which is known to improve mood. There is a direct connection between melatonin and serotonin, so a cooler environment may promote the production of both.
However, if your room is too cold, you'll either have to bundle up, which will cause you to feel hot later, or you'll be shivering and too uncomfortable to sleep deeply. As long as you feel comfortable, there are no health risks to sleeping in a colder room.

A cold room may not be good for your health
While sleeping in a cold room has its benefits, it may not be good for your health in certain circumstances. Firstly, if you are prone to getting chills at night, a cold room can be uncomfortable and keep you up all night shivering. This can lead to a poor night's sleep, leaving you feeling groggy and foggy during the day.
Secondly, a very cold room can lower your body's core temperature too much, potentially resulting in hypothermia. According to the Mayo Clinic, a core body temperature below 95 degrees Fahrenheit can lead to hypothermia, which is a dangerous condition.
Additionally, sleeping in a cold room can inhibit your body's ability to fight off illnesses like the common cold or flu. While cold temperatures do not cause sickness, they can reduce your body's immune function, making it harder to recover from infections.
Furthermore, for individuals with certain underlying health conditions, such as asthma or COPD, sleeping in a cold room can be detrimental. It is important for those with respiratory issues to consult a healthcare provider to determine the appropriate sleeping temperature.
Lastly, while not a direct health consequence, a cold room can increase your energy costs if you rely heavily on heating systems to maintain a comfortable temperature. This may not be feasible for everyone, and there are more affordable ways to stay warm at night, such as wearing warm clothing or using extra blankets.
In summary, while a cold room can promote better sleep and have some health benefits, it is important to be mindful of potential drawbacks. Ensuring that you are adequately warm and comfortable is crucial to maintaining a healthy sleep environment and avoiding any negative health impacts.
