Morning Hack That Melts Sleep Problems

A short clip from Huberman Lab says you don’t need to stare into the sun to help your body’s internal clock — just getting regular daylight into your eyes soon after you wake up can do the trick.

Quick Take

Ambient daylight, not direct sunlight, can help set your body’s daily clock.
Timing matters most: aim to get light in your eyes within the first hour after waking.
How long you need outside depends on how bright it is — sunny days need less time than cloudy ones.
Peer-reviewed research backs the basic idea that morning light shifts your body clock earlier.
Experts still say skip the sunglasses, but never stare straight at the sun.

What The New Guidance Says

Neuroscientist Andrew Huberman posted a clip called “How to Get Morning Light Without Direct Sunshine.” In it, he says the goal is simple: “get ambient daylight in your eyes in the first hour after waking.” That means you don’t have to stand outside staring at a sunrise. Cloudy skies, shade, or a bright window can still count, as long as the light reaches your eyes early in the day.

Huberman has repeated a similar message across other videos and newsletters for years. In one, he suggests aiming for roughly 100,000 lux of light exposure before 9 or 10 a.m., depending on when you wake up. That number sounds high, but it reflects how much brighter true outdoor daylight is compared with typical indoor lighting, even on a gray morning.

Why Timing And Brightness Matter

How long you need to spend outside changes based on the weather. Huberman Lab’s own newsletter recommends 5 to 10 minutes outside on a sunny morning, but says overcast days still work if you stretch that to 15 to 20 minutes. Other Huberman videos give similar ranges, generally 5 minutes on clear days and up to 20 to 30 minutes when it’s heavily overcast.

The advice also warns against two habits people often get wrong. Sunglasses should stay off during this brief morning window, since they block the light your eyes need to sense. At the same time, nobody should look straight at the sun, since that can damage the eyes regardless of how bright or dim the sky looks.

What The Science Shows

Outside of Huberman’s own videos, published research supports the general idea. Scientific reviews describe how light exposure shifts the body’s internal clock, noting that morning light tends to move the clock earlier while evening light pushes it later. Other studies show that bright light delivered shortly after waking can produce a measurable shift in the clock within the same day.

Researchers also agree that brightness levels affect the outcome. One analysis found that light below 1,000 lux, roughly the level of a lit indoor room, has little effect on the body clock, while stronger outdoor light produces a much bigger response. Federal workplace-safety guidance from the Centers for Disease Control and Prevention makes a similar point, noting the body’s internal clock is most sensitive to light exposure in the morning and evening hours.

Taken together, the clip’s core message lines up with what circadian researchers have said for years: morning light works best when it comes early, and its exact strength matters less than getting some form of it into your eyes on a regular basis. For most people, that means stepping near a window or outside soon after waking, rain or shine.
