Circadian Rhythm Reset

Resetting Your Circadian Rhythm

Before we reach for another supplement, we often need to go back to something more basic: rhythm.

Every cell in your body runs on a clock, and that clock is set by the world around you. The rising and setting of the sun, the cool of the night, the pull of the seasons and the moon. For most of human history our days moved with those cycles. Now we live under artificial light, eat at all hours, and scroll late into the night, and our bodies lose track of what time it is.

When the internal clock drifts, it shows up everywhere. Sleep is the obvious one, but the circadian rhythm also governs mood and stress hormones, digestion and bowel regularity (that morning urge to go is circadian), blood sugar, appetite, and weight. I often see stubborn constipation, low mood, wired-but-tired evenings, and weight that won't budge begin to shift once a patient's rhythm is restored.

Your circadian rhythm quietly runs almost everything. If we're not attuned to our environment the sun, the earth, the moon , we can't be fully attuned to our own bodies. The good news is that the clock responds to simple, daily cues, and you can start resetting it today.

Ideal Sleep Window (for adults and children)

• Asleep by about 9:00 to 9:30 PM

• Wake with natural light, about 6:30 to 7:00 AM

Tools for Circadian Reset

Light

• Get morning light exposure (outside or at a bright window) within 30 to 60 minutes of waking. This shifts your clock earlier.

• Get some light exposure at midday, which helps improve melatonin timing at night.

• Evening light shifts your clock later, so dim the lights after 8 PM.

• Avoid screens 1 to 2 hours before bed.

Temperature

• Keep your bedroom between 65 and 68°F.

• Take a warm bath or shower 1 to 2 hours before bed. As your body cools afterward, the drop in core body temperature signals that it's time to sleep.

Food Timing

• Eat your meals at consistent times each day.

• Eat your first meal within 1 hour of waking.

• Keep breakfast protein-forward.

• Finish eating at least 3 hours before bed. With a 9:00 PM bedtime, that means dinner wraps up by about 6:00 PM.

• Close the kitchen after dinner and avoid late-night snacking.

Movement

• Move your body daily. Morning activity in particular strengthens your circadian rhythm.

• Exercise at the same time each day when you can. Consistent timing is a strong signal to your internal clock.

Nervous System

• Brief morning cold exposure, like a cold rinse at the end of your shower or stepping outside, increases norepinephrine and helps anchor your circadian clock.

The whole family benefits

You and your little ones need a predictable rhythm that supports your brains and bodies. Consistency matters more than perfection. Small daily cues add up to better sleep, energy, and regulation.
