Circadian Rhythms
Circadian rhythms for cognition: Notes on the biochronology of health, resilience & performance
Cognitive performance and mood as well as variables of our physiology vary predictably over the daily, 24-h cycle. These rhythms are intimately linked with our cycle of sleep and wakefulness and are driven by our internal circadian clock, a biological pacemaker. Human’s performance and most biological functions express rhythmic fluctuations across a 24-h-period: an increase […]
Circadian Rhythms for Cognition and Health
We have evolved an internal biological clock, called the circadian rhythm, to help our bodies adapt to the daily cycle of day and night (light and dark) as the Earth rotates every 24 hours. The term “circadian” comes from the Latin words for ‘about’ (circa) and ‘a day’ (diem). Circadian Rhythm Basics Our cells contain tiny molecular […]
