Overheating In Bed

We have been talking about the adverse effects of overheating in bed now for over 14 years.

History of the Compatibility Blanket

The story began for us around 1998 when I invented the Compatibility Blanket to solve the nightly battle of the bedclothes between hot and cold bed partners.

At the time I thought that I was the only one with the problem with my partner in bed.

You know the story?  If the cooler/colder person of the partnership wins the bed coverings argument then the partner that feels the heat has to either

  • dangle their legs out the side of the bed to try to get cooler
  • pushes whatever bed coverings over to the other person’s side of the bed, which now make the other person uncomfortable, loaded up with coverings, dealing with heavy coverings, and is now probably too hot too because of the “extras” they have just been given!

Temperature Differences Between Bed Partners is Very Common!

I used to notice this in offices in Sydney often.  The guys walking around the office very happy in a shirt (tie or not), and often the women feeling cooler, even cold – having to wear a jacket or jumper/cardigan/extra layer on the top.

But no-one seemed to talk about the differences when in bed together.  Probably it is regarded as private, with no-one wanting to volunteer the information if the conversation didn’t ever come up.

Still, I found it weird that no-one had ever come up with a product to solve the problem until I did in about 1998.

The first Compatibility Blanket was sewn together by me when I lived on a remote sheep grazing property in country New South Wales, Australia.  Ironically, even having observed the office temperature differences, I still thought that I was the only person with the problem!

I’d been making my own clothes for many years, and done “miles” on a sewing machine, so bingo, it happened!

Then I started talking about it.  And finding out that other people had the same problem.  Like MOST of them.  In fact I had a one-blanket-difference in my bed, and some friends had up to about a three-blanket-difference in there’s!  Hmmm, what a discovery.

The Compatibility Blanket Helps You Sleep Better, and Improves Your Health

It was in the process of marketing the blanket that I started to realize there was a lot more about sleeping cool than I had previously thought.  Apart from the obvious compatibility problems around bed coverings.

It is absolutely recommended by all the experts to sleep cool.  But while one partner is sleeping cool, the other partner can be freezing!  So something had to be done.

The Compatibility Blanket was featured as a solution to overheating in bed on the ABC New Inventors television program

The Adverse Affects Of Overheating In Bed

So why is it bad to overheat in bed?

Here is some of the research, which I’ve copied over from my other website www.SleeplessNoMore.com

Overheating in bed reduces your rapid eye movement sleep, and the benefits derived from a good night’s sleep.

Overheating in bed reduces the quality of sleep.  We tend to sleep better when our body is cool.  In fact, the reason many people recommend a warm bath before going to sleep is because the drop in temperature experienced after having the bath brings on feelings of drowsiness.

Bed temperatures above 32 degrees C reduce rapid eye movement (REM) sleep, which is very important for quality sleep.  Overheating during REM sleep can be disruptive.

Without good REM sleep, you can wake up feeling unrefreshed, tired, and vague.  Some feel like they have a hangover, without having been drinking.

Associate professor Peter Cistulli, President of the Australasian Sleep Association says that doonas/duvets trap sleepers in a heat layer.  He agrees with others that blankets are more effective than doonas/duvets for regulating temperatures in bed – and they can provide a more uniform temperature than doonas.

Sleeping slightly ‘cool’ is a lot easier under blankets than under a doona/duvet – especially for the person who feels the heat.  If you do care about your partner’s sleep quality (and who doesn’t?) – listen to them when they say they’re too hot.

Apart from losing valuable sleep – overheating in bed, according to renowned skin specialists Dr. Hugh Molloy and Dr. Garry Egger, is also associated with:

  • ‘Doona Eyes’ – darkening of the skin around the eyes – with sufferers mentioning itchiness, flaking, swelling of the eyelids, and sleep in the eyes on waking.
  • Facial Dermatitis.  If facial rubbing occurs during the night other skin changes can become noticeable.  It can cause blackheads and whiteheads and acne on women who are well beyond puberty.
  • Peri-oral dermatitis.
  • Grover’s Disease.  Itchy red lumps on the upper chest of middle-aged men, a major factor being sweat entrapment.
  • Facial Excrescences.
  • Atopic Exzema and acne.
  • Hair and Scalp problems.
