Glycine and Slow Wave Sleep

Sleep quality is essential for good health and our genetics play a role in how much slow wave sleep we naturally get.

Depression, Genetics, and Circadian Rhythm

For some people, circadian disruption can be chronic – and at the heart of depression or mood disorders. Genetic variants play a role in this susceptibility. Fortunately, there are solutions that may help. ​

Lithium Orotate: Mood, Alzheimer’s, and Aging

Researchers found that Texas counties with higher levels of lithium in their groundwater had less of an increase in Alzheimer’s rates compared with counties that had lower levels of lithium. This isn’t a total surprise since previous studies had linked lithium to a decreased risk of dementia, but it is a great confirmation at a large scale population level.

Genetics of Seasonal Affective Disorder

Seasonal Affective Disorder (SAD) is characterized by recurrent depression with a change in the season usually in fall/winter for most. Scientists think this is possibly due to an aberrant response to light – either not enough brightness to the sunlight or not enough hours of light. Your genes play a big role in this responsiveness to light.

Bipolar Disorder, Depression, and Circadian Clock Genes

New research shows that depression and bipolar disorder are linked to changes or disruption in circadian genes. Some people carry genetic variants in the circadian genes that make them more susceptible to circadian disruption.

Melatonin: Key to Health and Longevity

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 light blocking glasses

Blue-blocking Glasses: Why? Which ones?

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.

Why light at night increases the risk for cancer

The World Health Organization (WHO) categorizes light at night as a probable carcinogen. Learn why dim light at night increases your risk of breast cancer — and what you can do to easily reduce this risk. (Member’s article)
