If your bedroom temperature is above 70° F, it's too hot.
If your bedroom temperature is above 70 degrees, experts say it's too hot. On the flip side, sleeping too cold also has its issues. It does not affect your sleep cycles as drastically as being too hot, but it could potentially lead to other health issues.
Tips for Keeping Cool During Sleep
A cool or lukewarm bath or shower can help with that, suggests Raymann. For most people, the temperature in the bedroom at night should not exceed 72 degrees Fahrenheit, and it should be even lower for people that sleep best in a cool bedroom.
They found a 5-to-10 percent drop in sleep efficiency when indoor temperatures rose from 77 to 86 degrees, he said. “The consensus among most scientists is that anything higher than 75 or 80 is bad for sleep and potentially detrimental to health,” Baniassadi said.
Research shows sleep can be disrupted by temperatures anywhere below 65 degrees Fahrenheit or above 75 degrees Fahrenheit. But for most people, heat interferes with sleep more than cold does. Sleep experts believe the best temperature for great sleep is between 68-72 degrees Fahrenheit.
In reality, the average range is anywhere between 68 and 76 degrees Fahrenheit. The ideal room temperature will vary according to season, activity, and the area of your home. During winter time, the standard temperature is around 70 degrees Fahrenheit.
If you can't keep your home at that exact temperature, or if 65 degrees is a little too chilly for your personal preferences, board-certified sleep medicine physician Funke Afolabi-Brown, MD, suggests aiming for something in the broader temperature range of 60 to 72 degrees for the best sleep environment possible.
Safe range means a set variation where there's minimal risk. If the room temperature is below 68 degrees Fahrenheit or above 74 degrees Fahrenheit, their health is at risk because the temperatures will be outside the safe range.
The best room temperature for sleep is approximately 65 degrees Fahrenheit (18.3 degrees Celsius). This may vary by a few degrees from person to person, but most doctors recommend keeping the thermostat set between 65 to 68 degrees Fahrenheit (15.6 to 20 degrees Celsius) for the most comfortable sleep.
How hot is too hot? “If someone told me that they slept in a temperature between 70 to 75, I'd say that's a range that promotes insomnia,” Avidan says. “That's toasty.” If you're used to keeping your bedroom so warm, “Lower the temperature 2 to 3 degrees at a time,” Ramos says.
Some research suggests that sleeping naked can promote better sleep, leading to various mental and physical health benefits. By encouraging core body temperature regulation, naked sleeping may help support reproductive function, skin health, cortisol levels, metabolic control, and more.
If your bedroom is too warm, as it can be in summer, then this can increase your body temperature. View Source and disturb your sleep. You are more sensitive to temperatures during the first two sleep stages, and thus more likely to wake up during these stages if you feel hot.
An influential limit. After an influential study in 2010, climate researchers often use a wet bulb temperature of 35 degrees C — roughly equivalent to 95 degrees F at 100% humidity — as an upper limit for human survival and adaptability without cooling.
What temperature should a bedroom be? Your body heat peaks late afternoon and then starts to drop in the evening to prepare your body for sleep, kickstarting melatonin production. An ideal bedroom temperature is around 16-18°C (60-65°F).
Heatstroke is a condition caused by the body overheating. This usually happens because of exposure to high temperatures or physical activity in high temperatures for too long. There are a few stages of heat injury, and heatstroke is the most serious. It can happen if body temperature rises to 104 F (40 C) or higher.
People aged 65 years or older are more prone to heat-related health problems. Stay cool and hydrated during hot weather. Older adults do not adjust as well as young people to sudden changes in temperature. They are more likely to have a chronic medical condition that changes normal body responses to heat.
It's important to note that feeling too hot in bed does not directly cause a fever. Fevers are typically a result of the body's response to infection, inflammation, or other medical conditions.
In general, 80 degrees is too hot for a house if people are inside.
It's advisable to keep your home below 80 degrees throughout the summer. A house that's too warm can be dangerous to people, pets, and the soft surfaces in your home. Set the winter temperature to 68 degrees when you're awake and 62 degrees when you're sleeping.
Sleeping too hot
“Heat is a huge disruptor for REM sleep,” Dr. Drerup says. With the heat of the room, your body temperature will also rise, thus undoing the sleep initiation process entirely. If your bedroom temperature is above 70° F, it's too hot.
According to Chester Wu, MD, a psychiatrist and sleep expert, one of the best sleep positions is side-sleeping. “This position is ideal as it helps maintain proper spine alignment, reduces snoring and sleep apnea symptoms, and is beneficial for digestion and heart health,” said Wu.
