Can Temperature Affect How You Sleep?



I’m hot but she’s not – and neither of us can sleep!

What keeps you up at night? Stress? Lumpy mattress? Sick child? You might be surprised to learn that temperature is often the single biggest defining factor between a good night’s sleep and one that leaves you grumpy and tired the next day. Every night across this great nation, the “I’m hot, she’s not” syndrome is robbing Americans of sleep.

Sleeping too hot leads to sweaty sheets. Sleeping too cold leaves you shivering. Neither is a pretty – or comfortable – way to spend the night.

We believe that sleep is a right, not a privilege. What’s more, we also believe that all this struggling over temperature throughout the night is needless. If you’re playing hide and seek with sleep it’s time to stop playing games and get serious about your sleep health.

Experts agree the temperature of your sleeping area and how comfortable you feel in it affect how well and how long you snooze. Why? “When you go to sleep, your set point for body temperature — the temperature your brain is trying to achieve — goes down,” says H. Craig Heller, PhD, professor of biology at Stanford University, who wrote a chapter on temperature and sleep for a medical textbook. “Think of it as the internal thermostat.” If it’s too cold or too hot, the body struggles to achieve this set point.

The importance of temperature control in your bedroom

When your body overheats or is chilled, it works hard to regulate the temperature to ensure your organs continue working and you stay alive (in extreme circumstances). But if it can’t control your temperature internally, it moves to more aggressive tactics, like making you sweat or shiver or increasing (or decreasing) your heart rate. If you’re asleep when your thermostat soars or dips, you’re in for a restless night and a not so great morning. Trouble is, our perception of temperature is as unique as our fingerprints – two people in the same bed can feel very different about the micro-climate (the temperature under the covers).

Is sleeping in a cold bedroom better for you?

Ask any insomniac about the perils of a hot pillow: When you’re trying to sleep, your brain loves the cold. Wearing a cooling cap helped insomniacs snooze almost as well as people without sleep problems, found a study from the University of Pittsburgh School of Medicine, and there’s also some evidence that yawning helps your brain offload heat before bedtime.

What temperature should your bedroom be?

During the course of a normal day, your body temperature rises and falls slightly. This pattern is tied to your sleep cycle. As you become drowsy, your temperature goes down, reaches its lowest level around 5:00 a.m., and climbs slightly as morning begins. This is why the air in your room can affect the quality of your sleep: if it’s too hot, it may interfere with your body’s natural dip and make you more restless through the night. In fact, studies indicate that some forms of insomnia are associated with an improper regulation in body temperature. Of course each of us has a slightly different optimal temperature for sleep, so experiment with keeping your room cool and find what makes you most comfortable. Read more on SleepFoundation.org

Outlast – the new temperature controlling miracle

Restonic mattresses contain Outlast, a NASA developed temperature controlling system that proactively regulates temperature to adjust to the body’s microclimate for optimum comfort. When it’s too warm, Outlast absorbs and stores the excess heat. Outlast then adapts to the body’s microclimate so overheating and sweating are reduced. As your skin cools, the heat is then released back to the body to maintain a balanced temperature. The cycle works continuously, compared to other performance materials that manage temperature and moisture by reactively pulling moisture away from the skin by wicking, Outlast technology proactively manages heat while controlling the production of moisture before it begins.
