Life as we know it is built around the sun’s 24-hour cycle. Your independent “body clock” – your circadian rhythm - also works on a 24-hour cycle, and is synchronized with the natural time cues of each day, like sunlight and darkness. The circadian rhythm not only regulates sleeping and waking states, but every biological system in the body. For this reason, circadian rhythms have a massive impact on health, disease and performance.
With modern, 24/7 lifestyles being heavily reliant on technology, our circadian rhythms are more misaligned with the solar cycle than ever, be it through travel jet lag, social jet lag (yes, that’s a real term) or night shift work. The resulting mistimed exposure to light and dark exposure can disrupt our internal processes, elevating the risk of illness or disease affecting cardiovascular, metabolic and gastrointestinal systems, mental health, contributing to the development of some forms of cancer and all-cause mortality.
