Sleep & Circadian Rhythm

Sleep & Your Genes

A quick overview article explaining sleep related topics such as insomnia, restless leg, narcolepsy, and circadian rhythm genes. Start here and then dive deeper into the specific topics.

Circadian Rhythm

The body's circadian clock regulates many different functions over the course of a 24-hour day. The genes that code for different parts of the circadian clock have a wide-ranging effect on sleep, mood, and overall health.


More than just a sleep hormone, melatonin is at the heart of many health topics. Your genetic variants play a big role in the production of melatonin. Learn how your lifestyle and diet interact with your melatonin-related genes.

Blue Blocking Glasses

An easy way to improve sleep and increase melatonin production at night is to wear blue light blocking glasses before bed. Explore the research on why this is so important, and learn about the different options available for blue-blocking glasses.

Mood Disorders & Sleep

There is a biological link between the circadian rhythm genes and mood disorders such as depression, anxiety, and bipolar disorder. Genetic variants in the core circadian genes increase your risk for mood disorders.

Restless Leg & PLMD

Many know the frustration of disrupted sleep due to RLS and periodic limb movement disorder (PLMD). Genes play a role in your risk for these disorders, and there are specific research-based solutions to try.
