INSIGHT

Circadian Rhythm Disruption's Wide-Ranging Effects

Circadian rhythm disruption, though subtle, has profound health impacts.
It increases chronic disease risks, affects productivity, athletic performance, and even life quality and longevity.

INSIGHT

Circadian Rhythm and Weight Gain

Circadian rhythm disruption links to overeating and weight gain, especially late at night.
Eating within three hours of bedtime increases obesity and diabetes risk and hinders sleep.

ANECDOTE

Mammoth Cave Experiment

In 1938, Nathaniel Kleitman and Bruce Richardson lived in Mammoth Cave on a 28-hour day.
The older researcher struggled to adapt, suggesting internal clocks are roughly 24 hours.

Our modern lifestyles have disrupted our natural circadian rhythms. Whether it's sleeping, eating, or exposing ourselves to light outside of our usual schedule, we're losing touch with these natural cycles and increasing our chances of developing disease.

Today, on The Dhru Purohit Show, Dhru sits down with Lynne Peeples to discuss how our daily habits are disrupting our inner clock and how this ongoing disruption can have long-term effects on our health. Lynne explains the link between circadian rhythm disruption, weight gain, and chronic diseases. She also uncovers the most common disruptors and the misconceptions surrounding them. Additionally, Lynne shares three key ways to immediately improve your circadian hygiene and why it's critical to align your day with your chronotype.
