Circadian rhythm and its impact on skin health

Author: Marionne de Candia  

The body’s circadian rhythm, better known as your sleep/wake cycle, is your personal 24-hour internal clock and runs constantly in the background of your brain alternating between sleepiness and alertness at regular intervals. When it’s dark your brain sends a signal to the body to release melatonin which encourages sleep and therefore the circadian rhythm is naturally in tune with the day to night cycle.

For most adults the biggest dip in energy occurs in the middle of the night, somewhere between 2am and 4am, usually when you are asleep. It also tends to occur around 1pm and 3pm when many of us feel like a post lunch nap. These times can vary however depending if you are a night or morning person. If you have a healthy sleep pattern you may not even feel the dips and rises in your circadian rhythms as strongly, however if you are sleep deprived you will notice far bigger swings in both sleepiness and alertness.

Circadian rhythms appear to have an impact on our skin health. Knowing what your body requires in terms of wake and sleep patterns is very important for vibrant and healthy skin. Recent research shows how important the body’s biological clock is in the regeneration of skin stem cells. When this clock is disrupted it can result in premature skin tissue ageing, dry flaky skin and breakouts.

Skin is exposed daily to many aggressors such as the ultraviolet rays of the sun as well as pollution and bacteria, consequently one of its most important functions is to protect itself against these. When the circadian rhythms are working well, stem cells which are constantly replacing damaged tissue, divide at least 30 times more rapidly at night than during the day which allows minimum exposure to skin from the damaging effects of ultraviolet light.   As Circadian rhythms in the skin affect the biology of its appearance, they also have a profound influence on the absorption of any product used on the skin.

Jet lag and daylight saving can disrupt this rhythm as can getting older.  It is difficult in today’s pressurised world but try to pay attention to what your body is telling you.  Go to bed and wake up at the same time as often as you can - this is when your circadian rhythms will work best for you and it will show in your skin.
