If you keep your bedroom temperature at 78 degrees Fahrenheit, you may be aware of the chilly sensation induced by sleeping in a pool of sweat. To wake up feeling renewed and refreshed, sleep experts recommend setting air conditioners to 70 degrees or lower to find the ideal combination of comfort and energy efficiency. According to Energy Star, a program administered by the United States Environmental Protection Agency and the United States Department of Energy, thermostats should be set to 78 to 82 degrees Fahrenheit (26 to 28 degrees Celsius) while sleeping.

However, this has sparked a heated discussion, with sleep specialists claiming that being too warm might generate a cold bedroom environment. According to sleep psychologist Michelle Drerup, PsyD, a bedroom should be regarded as a “cave,” with the temperature kept between 60 and 67 degrees. “It should be cool, dark, and quiet to improve your sleep,” Drerup advises the Cleveland Clinic. “If your bedroom becomes too hot or cold, you are more likely to wake up. “Our bodies naturally cool during sleep to facilitate deeper rest stages, which are an important part of the restorative sleep cycle.”

In fact, a research found that too much “heat or cold exposure” can lead to “increased wakefulness and decreased rapid eye movement (REM) sleep” – the stage during which we dream. “Thermoregulation is very important for staying in restorative, slow-wave sleep stages,” says the physician, who continues, “these are the stages in which we get the most rest.” Too hot or too cold. Let’s look at how temperature settings affect sleep quality, energy efficiency, and general health, as well as the best options for overnight cooling.

Sweat and discomfort. During sleep, the body expels heat to lower core temperatures. To aid this process, doctors recommend keeping the temperature relatively chilly, which promotes deeper and more restorative sleep cycles. “If your bedroom temperature is above 70 [degrees], it’s too hot,” which can create discomfort, particularly under blankets, resulting in sweating and frequent tossing and turning.”Heat is a huge disruptor for REM sleep,” Dr. Drerup explains. Sticky and unwelcoming. Warm temperatures may feel nice during the day, but at night they can create a sticky and uninviting environment.

For individuals living in humid areas, air conditioners set at a higher temperature may struggle to dehumidify the air, leaving the space moist and unpleasant. Individuals with respiratory difficulties may experience increased discomfort and difficulty breathing as a result of this. inefficient cooling Air conditioners set to 78 degrees may take longer to provide a comfortable sleeping environment, especially on hot summer evenings. This can extend cooling durations, thereby increasing energy use and undermining the goal of energy savings.

Health risks of overheating. Overheating while sleeping can cause headaches, dehydration, and discomfort. Individuals with asthma or other medical disorders may have worsening symptoms. Grumpy and sluggish. Warmer settings can cause greater restlessness and activity during sleep. This can lead to trouble falling asleep, frequent awakenings, and a reduction in overall sleep quality. As a result, you can feel sleepy and unrefreshed in the morning. Impaired air circulation.

At 78 degrees, air conditioners may not circulate air adequately, resulting in uneven temperatures and uncomfortable hot patches across the room. Lowered air quality Higher room temperatures may allow allergens and pollutants to move more readily, especially if the AC’s dehumidifying function is reduced. This might aggravate respiratory problems and reduce the quality of sleep. Disrupted REM sleep. A warm room may hinder the body from reaching the low temperatures required for REM sleep, which is essential for cognitive function and emotional wellbeing.

Poor REM sleep can cause impaired focus, emotional swings, and trouble waking up refreshed. Misconceptions regarding energy savings While adjusting the AC to 78 degrees may appear cost-effective, the energy savings are frequently minimal. Lowering the temperature slightly can help to chill the room faster, allowing the air conditioner to turn off sooner and saving electricity overall.

Furthermore, if a room is too warm for pleasant sleep, you may find yourself adjusting the thermostat frequently, which can result in higher energy use than planned. at get the best sleep, set your air conditioner at 60 to 67 degrees. This series contributes to a cool and comfortable environment, promoting restful sleep, improved air quality, and energy economy.
