It goes without saying that lack of sleep can exhaust anyone. It influences our ability to think, work, analyze and correctly react to daily events. In addition, it is the easiest way to become a complete psycho. Numerous worldwide researches have proved the damaging effects of sleepless nights (for those interested in detailed scientific data and figures, Division of Sleep Medicine at Harvard Medical School posts lots of information about various researches on their web site). This article, however, is dedicated to the connection between sleep and beauty. And let me be straight from the very beginning: the connection is undeniable.

Sleep is one of the most important physiological processes. While we are sleeping, our skin cells are at work: they are being renewed almost twice faster than during the day. As a result, skin gets rid of many toxins and wrinkles and gets enriched with collagen. Lack of this protein (collagen) is the reason for dry skin, lines, cellulite, dull hair, etc. Rapid process of skin renewal is the no. 1 reason for keeping your skin clean and removing any makeup before going to bed.

Looking through various materials and research data to back up my statements in this article I discovered an interesting fact: sleep can be helpful to those trying to loose extra weight. It turns out that lack of sleep may cause imbalance of hormones responsible for burning calories. Therefore, healthy sleep is a great addition to dieting and work outs.
