Why Your Body Runs on a Schedule (Circadian Rhythm Explained) | Dr. Bill Berkowitz

Описание: Your body runs on a circadian rhythm, which is a 24 hour internal clock that coordinates sleep, hormones, metabolism, digestion, and brain function. This biological clock is primarily controlled by light and darkness. When light exposure and daily timing are consistent, the circadian clock stays aligned. When light, sleep, and activity are irregular, the system becomes disrupted and performance declines.

Circadian rhythm problems often affect people who feel tired, foggy, or wired at night but cannot sleep. Many assume this is caused only by stress or aging. In many cases, the real issue is circadian misalignment. The body expects bright light in the morning, activity during the day, and darkness at night. Indoor lighting, screens, inconsistent sleep timing, and late evening stimulation can confuse the biological clock and delay melatonin release.

The circadian rhythm explained simply is timing and sequence. Morning light signals the brain to lower melatonin and raise cortisol for alertness. As light fades, melatonin rises to prepare the body for sleep. When this rhythm is shifted, metabolism, mood, and energy regulation can suffer. A circadian rhythm reset usually begins with consistent wake times, early daylight exposure, reduced evening light, and predictable sleep timing.

In this video, you will learn:
How the circadian rhythm controls sleep, hormones, and energy regulation.
Why common daily habits disrupt the biological clock.
5 time shifts that reset your circadian rhythm naturally.

FAQs

What is the circadian rhythm?
The circadian rhythm is the body’s internal 24 hour clock that regulates sleep, hormones, metabolism, and alertness based on light and darkness.

How does light affect the biological clock?
Morning light signals the brain to increase alertness hormones, while darkness allows melatonin to rise and prepare the body for sleep.

What causes circadian rhythm disruption?
Irregular sleep schedules, late night screen exposure, indoor lighting, shift work, and inconsistent daily routines can all disrupt the circadian clock.

How do you reset your circadian rhythm?
A circadian rhythm reset typically involves consistent wake times, early morning sunlight exposure, reduced evening light, and regular sleep timing.

How long does it take to fix a disrupted circadian rhythm?
In many cases, noticeable improvements can occur within several days to a few weeks if light exposure and sleep timing are consistent.
