How does Dr. Karan Rajan say sleep affects digestion?

Dr. Rajan explains that consistent sleep helps synchronize the gut's internal clocks with the brain's master clock, promoting regular bowel movements.

What is 'social jet lag' and how does it impact my gut?

Social jet lag from inconsistent sleep times disrupts gut motility, potentially causing stool to dry out and leading to constipation.

Can my phone use at night affect my bowel movements?

Yes, late-night phone use delays melatonin, which can slow gut movement and shift or skip your natural 'I-need-to-go' window.

Summary

Consistent sleep is crucial for predictable bowel movements.
Gut health relies on internal circadian clocks synchronized with the brain.
Irregular sleep disrupts gut motility and microbial balance.

The connection between sleep and digestive health is profound, extending beyond common fatigue. Irregular sleep patterns can significantly disrupt the colon's natural functions, leading to issues such as constipation and inconsistent bowel movements. This disruption stems from the gut possessing its own internal timing systems, known as circadian clocks, which are synchronized with the brain's master clock.

When sleep schedules become erratic, this vital coordination breaks down. The brain's signals to the intestines can become mistimed, causing sluggishness or overactivity. This effect is exacerbated by 'social jet lag,' where varying sleep times dry out stool and lead to constipation, even with adequate fiber intake. Late-night phone use further delays melatonin, slowing gut movement and potentially causing digestive windows to be missed.

The gut microbiome also adheres to a daily rhythm, with different bacteria peaking at specific times. Irregular sleep leads to chaotic microbial timing, which in turn results in chaotic bowel function. To promote regular bowel movements, establishing a consistent bedtime and wake time, ensuring morning light exposure, and avoiding late-night meals are essential, alongside fiber, hydration, and exercise.
