Can It Cause Nightmares
The myth that sleeping in a cold room can cause nightmares continues to persist, even though there is no evidence supporting it.
That being said, any room that is uncomfortable can influence our sleep patterns and could cause nightmares. While a cold room alone wont cause nightmares, if a room is either too cold or too hot for your liking, you may be more likely to have a bad dream.

So Why Did We Evolve To Be Colder At Night
This is still largely mysterious, but there are a few possible ideas out there that scientists are exploring.
Metabolism can drop 10% when you sleep and that may have been a long-ago adaptation
There has been some evidence that this daily cycle of body temperature helps control other daily cycles in the body, such as in the liver and kidneys. “There are a few studies that suggest that even the small 1°1.5°F change in core body temperature is sufficient to be the cue that synchronizes these cell populations throughout the body,” says Christopher Colwell, a professor of psychiatry at UCLA who studies circadian rhythms. “But its not definitive at this point.”
Another possibility is that decreased metabolism is actually one of the reasons for sleeping to begin with. Metabolism can drop 10 percent in sleeping people.
If you think about our evolutionary ancestors struggling to find enough to eat, it would be handy to have periods where we used as little energy as possible. This hypothesis might help explain why many creatures sleep at night rather than during the day. Night is colder than day so warm-blooded creatures would have to expend even more energy to stay warm if they were awake. Better, then, to go into somewhat-stasis mode and save energy up for only the few hours of eating, mating, and other activities required for survival.
Warm Your House For Less
Want to keep your house warm without the sting of an excessive heating bill? There are a few more eco-friendly things you can do to keep your bedroom at a comfortable temperature for less money.
Invest in a programmable thermostat. Drop the temperature a few degrees while you are at work and in the middle of the night. Have your furnace kick in before you come home and when you get out of bed in the morning. You will be heating the house when you need it the most, and saving energy when you are away or bundled up in bed.
Find and repair the source of cool drafts. You may have to re-caulk windows or invest in a plastic window covering kit to keep out cool air during the winter. If there is a draft coming in under your bedroom door, roll up a towel or blanket and place it at the base. Check outside doors as well too make sure they prevent drafts.
Use your stove or oven to cook supper it will add a little heat to the air while you make yourself a meal. Just dont forget to turn the oven off when you finish.
Space heaters may also offer more concentrated heat where needed in larger, more open homes. This can be more efficient than heating a large house, depending on the space heater. Always be sure to check safety information and inspect before a new season.

Why Cant People Sleep If It Is Too Hot Or Too Cold
A room that is too hot or too cold can make it difficult for people to sleep well, and it can cause common issues such as restlessness, difficulty falling asleep, and waking up in the night. A room that is too hot also causes more sleep disturbance than one that is too cold.
Furthermore, a room that is too warm can cause discomfort, restlessness, and sweating, which may lead to dehydration. suggests sleeping in an overheated room may also increase wakefulness, making it hard to fall asleep, and decrease sleep efficiency, leading to fatigue. High temperatures may also reduce appetite and increase heart and respiratory rates.
A persons core body temperature drops before bedtime as the core distributes heat and blood to the extremities, which causes warmer hands and feet. A core body temperature that is too warm and therefore not sending heat to the extremities may reduce the amount of restorative slow-wave sleep and sleep quality a person receives. A high core body temperature can also decrease sleep efficiency and cause frequent waking.
In contrast, sleeping in a room that is too cold may make it harder to fall asleep and sleep deeply. A 2021 animal study suggests that, compared with a control temperature of 73.4°F , temperatures of 59°F and 64.4°F have links to poor sleep quality, increased interruptions during sleep, and reduced delta wave activity associated with deep sleep. The lower temperatures also increased blood pressure and heart rate.

How Cold Winters Affect Sleep
While your indoor air and bedroom environment will likely play the biggest role, there a few ways that winter weather can affect sleep aside from changes it brings in indoor temperatures.
Winter days are shorter and the weather often keeps people bundled up or indoors. The dark nights can be good for turning in early, but they also dramatically reduce the amount of sunlight exposure for many people, which can affect circadian rhythms.
This can make you feel sleepy and sluggish all day, and throw off your bedtime at night leading to late nights and oversleeping or undersleeping. Experts suggest getting out in the sunlight first thing in the morning, and to limit bright lights and electronics at night.
For those who cannot get a daily dose of sun, bright light therapy has been shown to improve symptoms of seasonal affective disorder and other circadian rhythm disturbances.
Cold winter air typically contains less moisture and humidity than other seasons. Using electric heaters to warm the room temperature also contributes to indoor dryness, which can dry out mucous membranes and skin. When your nose dries out, this can force you to open your mouth at night to breath, leading to snoring and affecting how well you sleep.

While You’re At It Be Naked Too
Being cold is better for your sleep cycle, but so is being naked. Put the two together and you’re a regular sleeping beauty. Dr. Natasha Turner suggests that sleeping naked might help your body release growth hormones, which in turn helps you sleep deeper, lowers stress, and assists in releasing more oxytocin if you’ve got someone to cuddle.

Choose The Right Sleepwear
If you wont consider sleeping naked during hot nights, then its time to rethink your summer PJs.
Science says that light, thin materials like cotton aids sleep in the heatas it draws sweat away from your body while still letting your skin breathe.
Clothing that exposes hands and feet are also encouraged, as we lose most heat through our extremities.
How Temperature Impacts Sleep
Weve all experienced a terrible nights sleep. We wake up the next day feeling groggy and moody, moving slowly and looking forward to the moment we can once again shut our eyes and get some rest.
There are several factors that can contribute to sleeping troubles, one being temperature.
If your bedroom becomes uncomfortably hot or cold, you are more likely to wake up, says Dr. Drerup.
But why is this the case? One study shares that too much heat or cold exposure is directly linked to increased wakefulness and decreased rapid eye movement sleep . Thermoregulation is very important for staying in restorative, slow-wave sleep stages, says Dr. Drerup. These are the stages in which we get the most rest.

Wear The Right Clothes To Sleep
The right clothing at night can help you sleep. For example, consider wearing socks to bed. Your feet and hands tend to be colder than the rest of your body. Wearing socks can heat your feet, opening up your blood vessels and enabling your body to maintain a stable core temperature.
As for your pajamas, wool or cotton fabrics could be good choices. In one study of older adults, those who wore wool sleepwear fell asleep faster, and enjoyed better quality sleep, than those who wore cotton or polyester. Their bedrooms were on the warmer side, at 86 degrees Fahrenheit and 50% humidity.
In another study, those who wore wool sleepwear in a bedroom measuring 63 degrees Fahrenheit fell asleep faster than those who wore cotton. When the thermostat was set to 72 degrees Fahrenheit, however, wearing cotton sleepwear was associated with more time spent in deep sleep.
How Cool Temperatures Affect Sleep
Sleep and wake cycles are governed in large part by our circadian rhythms. Around when we should be heading to bed, our body temperature takes a slight dip and stays lower until close to wake time. Body temperature also drops slightly in the early afternoon, coinciding with post-lunch sleepiness.
Science has yet to discover definitive causation between body temperature and sleep, but studies have shown connections. It appears that when temperatures are cool, this facilitates deep sleep. In contrast, warm temperatures may make sleep less restful.
In a Huffington Post article, professor Michael Decker, Ph.D., spokesman for the American Academy of Sleep Medicine, discusses temperature and rest. As we sleep, our body acclimates to the room temperature, he says. If we lower our body temperature a little bit in a cooler room, we tend to sleep better.
Dr. Christopher Winter went into more detail in another article, saying that the sleep cycle is typically initiated when our core body temperatures drop, and that people with higher internal temperatures may have trouble sleeping when the room is not cool enough to allow this to occur. Studies he mentions find that ideal temperatures are between 60-67 degrees, with cooler temperatures in this range being linked to deeper sleep.
A few studies have also looked at how temperature can affect sleep both in terms of biological impacts and on sleep quality.
