In our hyper-connected modern world, where we have access to artificial light and food around the clock, we’ve drifted far from our body’s natural rhythms. But what if reconnecting with these internal clocks could be the key to unlocking better health, more energy and even a longer life?
This week's guest is Kristen Holmes, Global Head of Human Performance and Principal Scientist at WHOOP, a Science Advisor to Levels Health and Arena Labs, and a member of the Tactical Leadership Board of Sports Innovation Lab.
In this conversation, we explore the world of circadian biology and how aligning our daily habits with our natural rhythms can transform our health. Kristen explains the far-reaching consequences of a disrupted circadian rhythm, from metabolic disorders and increased ageing to mental health challenges and lower immune function.
We discuss the critical importance of consistent sleep/wake times, even on weekends, and how this simple change can dramatically improve our psychological and physiological functioning. Kristen shares her personal experience of how aligning her circadian rhythms has boosted her productivity, focus, and overall health – she hasn’t been ill for over eight years.
Throughout our conversation, we explore strategies for harmonising our circadian rhythms within the context of modern life. We cover the importance of morning light exposure, the ideal meal timing, and how to manage factors like alcohol and caffeine consumption. Kristen also advises shift workers on maintaining healthy rhythms despite irregular schedules.
Circadian Rhythms: The Foundation of Health and Longevity
- Circadian rhythms are the physical, mental, and behavioural processes occurring over a 24-hour cycle.
- Circadian alignment (matching internal preferences with the light-dark cycle) is considered the foundation of health and longevity. When the circadian rhythm is not functioning optimally, any attempts to improve health through nutrition or exercise protocols will be less efficient.
- Misaligned or desynchronized circadian rhythms are associated with an increased risk of metabolic disorders and metabolic dysfunction. Furthermore, not a single mental health disorder exists that circadian rhythm disruption doesn't touch.
- The desynchronization causes cellular miscommunication, which is considered the basis of most disease and aging.
- Modernity, specifically 24/7 access to light and food, creates enormous stress on the system and leads to misalignment.
