Genetic Test of Sleep

The Genetic Test of Sleep allows you to compare your established daily rhythm and your internal rhythm arising from your genetic disposition (i.e. whether you are more likely an evening type or a morning type) and its impact on your cognitive and athletic performance, eating behaviour and metabolism.

Your attention and performance at different times of day are determined by chronotype, which has been proven to have a significant genetic component.

For optimum functionality of your body, the signals from the external environment and the body’s internal signals must be in sync. This requires continuous adaptation, which takes extra effort and energy from the body. In extreme cases, conflict of biological and social clock may affect our quality of life because of low performance during normal working hours, and lead to sleep deprivation. This in turn may cause excess food and alcohol consumption, as well as psychological and weight issues.

The results of the Genetic Test of Sleep indicate:

  • Whether you are more likely a morning type or an evening type (or intermediate type);
  • How does sustained wakefulness impact your muscular activity and awareness of external environment;
  • How well is your body restored in deep sleep;
  • Do you have a risk of developing DSPS*;
  • How does your chronotype affect your eating behaviour;
  • What is your peak athletic performance time;
  • How does your body respond to external factors affecting mental capacity?
*Delayed Sleep Phase Syndrome

NB! If the results of the genetic test correspond to your established rhythm, then the body should function optimally. If the test result differs from the established/forced daily rhythm, it may lead to sleep disorders and functional imbalance in the body. The body functions more efficiently when the social and biological clock are synchronized. We do not recommend this test for children and people under 18 years of age, because due to biological and genetic reasons, the results of the genetic test might not match their established daily routine.

If you want to learn about your diurnal preference of activity and sleep rhythm, you can fill in the Horne-Östberg Morningness-Eveningness Questionnaire for determining the chronotype here.


This test is a good addition to our previous genetic tests (Genetic Test for Weight Management or GTWM and Genetic Test of Athletic Abilities or GTAA).

It is very easy to take the test! After receiving your order, we will send you a test kit. For taking your DNA sample, rub the inside of your cheek with the sterile cotton swab included in the kit, let it dry properly (in the upright position), and then mail the sample to us. The results will be available and sent to your e-mail address within ten days.

The role of genetics in determining diurnal preferences

Have you felt more forgetful and less focused after a sleepless night? Have you noticed that some of your friends are active already early in the morning, while others would sleep till noon and prefer to work late at night? These are but a few examples of the effect sleep may have on us, our productivity and even our health.
