1. They make a habit of napping
It’s been shown that lack of sleep causes weight gain, leads to a compromised immune system and increases the production of cortisol, a hormone that triggers stress.
But Sarnoff Mednick, professor emeritus of psychology at the University of Southern California, doesn’t worry about such things.
As profiled by Gene Stone in his book The Secrets of People Who Never Get Sick, Mednick would take an afternoon nap for most of his adult life and never suffered from colds or flu.
The fact is, until about the 13th century and the invention of mechanical clocks, humans napped daily.
The best time for a short snooze: Between the hours of one and three in the afternoon.
Most of us ditched our daily naps after preschool, but scientific experiments suggest that was likely a mistake.
Having a snooze – even one as short as ten minutes – can improve alertness, memory and cognitive performance.
2. They skip the nightcap
Although you may feel as though you fall into a deep slumber after a night of drinking, alcohol actually disrupts your sleep cycle and compromises the quality of your sleep.
Sleep is so wonderfully restorative to your immune system; cutting back on drinking will help your body protect against harmful germs you might be encountering.
Trouble nodding off? There’s no blanket solution for insomnia. But if you’ve tried everything, here may be the bedroom secret that helps you reclaim your night-time rest.
3. They love to drink tea
The act of drinking tea – as well as inhaling the steam that’s produced by a hot beverage – will stimulate hair follicles in the nose, making it easier for you to move germs out of your nose when you breathe.
Different teas have very distinct characteristics, which can affect not only how they are drunk, but at what time of day.
