SunUp Reminder

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.

• Precise sunrise reminders based on your GPS location
• Automatically adjusts as sunrise shifts through the seasons

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.
