Why Sleeping in a Cold Room Improves Your Health

Have you ever given much consideration to the temperature where you fall asleep? I have not. Turning on a fan or opening/closing windows is almost always a game-time choice for me personally, right when I am going to hit the hay.

My feet and hands are always cold, so I like to jump in bed once the sheets are not ice cold. However, if it is too hot (particularly with my furry baby creature heaters,) I will awaken in the middle of the night uncomfortable and hot.

Is there an optimum sleeping temperature? Science says there is.

Temperatures over 75 degrees and under 54 levels can interrupt sleep.

Why?

Over a 24 hour period, our own body temperatures obviously peak and decline. Our internal temperature is usually at its highest in the morning and lowest around 5 a.m.. When we fall asleep, our bodies naturally cool off. Helping your body get to that lower temperature quicker can promote deeper sleep.

Cameron Van den Heuvel, of this UniSA’s Centre for Sleep Research, says:

“About one to one and a half hours before falling sleep, the body starts to lose heat from its central core and that brings on increased feelings of tiredness in normal healthy adults. These physiological changes happen well before going to bed and may be occurring before people realize them.”

Benefits Of Cold Sleeping

There are many reasons that sleeping in a cooler setting can benefit your wellbeing. Listed below are four motives to stay cool tonight:

1. Fall Asleep More Instantly

It is simple math, really. Provide an environment for your body to fall asleep more comfortably, and it will, in a faster manner. When it’s too hot or too cold, your body will waste energy trying to regulate and leave you tossing and turning all night.

2. Get A Better Night’s Sleep

When your body isn’t trying to regulate itself, you’ll fall into a deeper, more restorative sleep. Research in Australia has also proven that sleeping in cooler environments can help decrease certain types of insomnia

3. Look More Youthful

It’s been shown that sleeping in temperatures between 60-68 degrees will allow your body to release more melatonin, one of our best anti-aging hormones.

4. Decrease Your Risk For Certain Metabolic Diseases

In a four-month study, it was determined that sleeping in a 66-degree room not only burned more calories while awake, but the amount of “brown fat” (or good fat) in the body increased. Brown fat allows your body to burn calories, not store them.

Together, this could help lower the risk for metabolic diseases like diabetes over time.
