The National Sleep Foundation has recommendations adults between the ages of 18-64 to sleep 7-9 hours per night. Sleep duration and quality can affect many things including muscle building, recovery, weight loss, learning and cognition. We test for the Circadian Locomotor Output Cycles Kaput (CLOCK) gene. Your result tells you whether you carry a genetic variant associated with a disturbed circadian rhythm and whether you are likely to be a night owl, morning lark or somewhere in between.

More about CLOCK

Your circadian rhythm, also known as your 'body clock', is an internal system that helps synchronize your body with the hours of sunlight and regulates feelings of sleepiness and wakefulness over a 24 hour period. The body’s master circadian clock is found in a region of the brain that responds to light. This is why we are alert when the sun is shining and are ready to sleep when it is dark.  A disturbed circadian rhythm can affect appetite, weight loss, learning, memory and physical performance.  Although circadian rhythm can be disturbed by factors such as environment, diet and occupation, carrying certain genes can also disturb the circadian rhythm.
