I just read an interesting study that indicates that core body temperature might play a vital role in sleep. The study, done by the University of South Australia, shows that the body needs to drop its core temperature for sleep to occur naturally. The drop in the body’s core heat brings on increased feelings of tiredness in normal, healthy adults.
If the core temperature stays high, however, people have trouble falling asleep or staying asleep, the study shows.
There’s more about this in the University of South Australia article "Getting to the Core of Insomnia", but if you’re having trouble sleeping, you might try opening a window, turning the thermostat down, wearing lighter bedclothes, or turning on a fan. And maybe instead of warm milk, you might try drinking a glass of iced lemon balm tea before bedtime.
I do know that for years now I haven’t been able to sleep in a warm room, and have trouble sleeping if I can’t open at least one window. Having a dog and cat doing their best to sleep on top of me doesn’t particularly help with the staying-cold part of the program. But I’m completely willing to test this thesis.
Since various studies put the number of Americans who have trouble sleeping at 25 to 50 percent of the population, this is an issue a lot of us have to cope with. Wouldn’t it be wonderful if the answer, after all, is … “Chill!”
