According to the experts, we don’t establish our circadian rhythms until we are about six weeks old. That’s about the time when babies can hold more milk in their bellies to sleep longer periods. Sleep helps us fight illness, manage stress AND keeps our skin youthful and fresh.

When we are tired, our skin will look tired too. Lines deepen and look more ingrained, the complexion looks dull and eyes are often shadowed. When we get enough rest the sleep hormone, MELATONIN, is able to go to work. It lowers blood pressure and core body temperature, regulates hormonal levels and increases our alertness the next day. Just losing one hour of sleep a night can reduce day-time attentiveness by one third.

And to add insult to injury, because the lack of sleep interferes with ghrelin and leptin – the eat and don’t eat buttons in our bodies – we tend to snack irregularly and eat more sugary and starchy foods. This leads to a spike in our sugar levels, creating glycation and inflammation. Check out my recent blog “The Not So Sweet Side of Sugar“. This can age us very rapidly, create break-outs, wrinkles, rosacea, dryness, and even depression and chronic illness.

So, if you can get eight hours of sleep a night – perfect. If not, try napping. Recent studies have established that just a short nap can clear and recharge the brain just as effectively as a longer sleep. Your eyes and skin will be brighter and you will be more productive each and every day.
