Circadian Rhythm

Your circadian rhythm is set by the oscillation of a core circadian clock. Just like the sun rises and sets every day, you have a daily rhythm inside of you, controlling a lot of your cellular functions.

Researchers have recently discovered just how extremely important your circadian rhythm is to your overall health and wellbeing. Disrupting your circadian rhythm can cause weight gain, mood disorders, heart disease, diabetes, and dementia.

Your genetic variants play a big role in why and how you are susceptible to chronic diseases due to circadian rhythm disruption. Some people are more resilient than others, and you can hack this system to improve your health.

Lithium: A mineral that affects mood, Alzheimer’s disease, obesity, and telomeres - 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.
