Get notifications at sunrise - a Huberman health hack.
The #1 habit Dr. Andrew Huberman recommends — automated.
If you've listened to the Huberman Lab podcast, you know: getting sunlight in your eyes within the first hour of
waking sets your entire day. It spikes cortisol at the right time, sharpens focus, boosts immunity, and programs your
body to fall asleep easily that night.
The problem? Sunrise shifts by hours through the year. Most people mean to do it — and forget.
SunUp fixes that.
——
Every day, SunUp calculates the exact sunrise time for your location and sends you a reminder — automatically. No
alarm to set. No time to remember. Step outside for 10 minutes and you've completed the habit that anchors your
circadian rhythm.
Clouds? Go anyway. Huberman's words: "even if through cloud cover" — the signal still reaches your eyes.
SET IT ONCE. NEVER THINK ABOUT IT AGAIN.

WHY THIS HABIT MATTERS
Prof. Andrew Huberman of Stanford explains: morning light triggers an early-day cortisol spike at the ideal time,
preparing the body for deep sleep that night. It also sets your circadian clock — the master timing system controlling
sleep, hunger, metabolism, and focus.
Miss the morning light and the whole rhythm shifts. Get it consistently and sleep, energy, mood, and focus all
improve.
SunUp makes sure you never miss it.
Download SunUp. Step outside. Start tomorrow.

After more than two years I decided to give SunUp some lovin'. Redesign and many new settable options, including sunrise timer offset and streaks.
