How HVAC Can Help Improve Your Sleep Quality

How HVAC Can Help Improve Your Sleep Quality

Ask any group of people whether they sleep in a cool or warm bedroom, and opinions will almost certainly be split! According to scientific research, it may seem like a matter of personal preference, but there actually is an optimal sleeping temperature of 60 to 72 degrees Fahrenheit. The circadian rhythm regulates the human body, and our temperature shifts a couple of degrees throughout the day before dropping at night. This is to help your body cool down and get ready for bed; that’s why sleeping in a colder room is preferable.

Before you rush off to call a heating and air conditioning company in Knoxville, let’s take a look at how sleeping in a cold room can be beneficial.

Prevention of Certain Diseases

According to the American Diabetes Association, individuals who sleep in a cold bedroom exhibit a reduced risk of metabolic diseases like diabetes. Over a period of 30 days, the people who slept in a cold room had a higher percentage of ‘brown fat’ than those who slept in a hot room. Brown fat is the good kind of fat you keep hearing about! The cold room group also burned more calories each day and had better insulin sensitivity!

Say Goodbye to Insomnia!

If you have trouble sleeping at night, lowering the temperature in your bedroom could help to eliminate those bouts of insomnia. In a study performed by the University of Pittsburgh School of Medicine, individuals with chronic insomnia wore cooling caps to bed. Participants fell asleep faster and stayed asleep longer. You can achieve the same effect by lowering the temperature in your bedroom. That doesn’t mean your whole house has to be cold - talk to a heating and air conditioning company in Knoxville about zoning your HVAC system to allow smaller areas around the property to have differing temperatures. That means you can keep the lounge area cozy while your bedroom is comfortably cool to aid your sleep.

Better Quality of Sleep

If you are one of the many people who do not actually have any trouble falling asleep but still wake up feeling exhausted, it could be that you are not sleeping deeply enough. REM sleep is crucial in allowing our bodies to reset overnight, leaving us refreshed and ready to face the day. However, although you may be asleep, you may not be sleeping deeply enough to enter the REM stage. One of the biggest causes of this is sleeping in a too-warm room. If you want to improve the quality of your sleep, a heating and air conditioning company in Knoxville can help by configuring your HVAC to keep your bedroom comfortably cool at night!

Keep Those Wrinkles At Bay

When we sleep, our bodies produce melatonin which plays a big part in boosting our immune systems and fighting free radicals which can age the skin. However, melatonin slows or even stops when the temperature is over 70 degrees Fahrenheit. Who would have thought calling on a heating and air conditioning company in Knoxville could slow the aging process!

How to Cool Your Room

So, now that you know the benefits of sleeping in a colder room, how are you going to make that change? Calling a heating and air conditioning company in Knoxville to discuss the best ways to cool your room via an HVAC system is the best option, but some other solutions include:

  • Choose bedding made from breathable fabrics like linen or eucalyptus
  • Drink plenty of water to help cool and hydrate your body
  • Choose a bedroom on a lower floor of your house if possible - heat rises!
  • Close your blinds during the day to stop the sun causing a build-up of heat in the room
  • Poke your feet outside of the covers to let heat leave your body more easily
