Introducing SunSeek: Get Your Daily Light Exposure

May 21, 2023

We're thrilled to announce SunSeek! An iOS app that helps you find the sun and get your daily light exposure.

What is SunSeek?

SunSeek is an iOS app that helps you locate the sun to get your daily light exposure.

What is Daily Light Exposure?

Daily Light Exposure (DLE) is the practice of regular exposure to natural sunlight to promote various health benefits. By influencing our biological functions, especially the circadian rhythm, DLE can enhance mood, sleep quality, and even the immune system. It's an essential yet often overlooked aspect of holistic health and well-being.

Learn more about DLE from Dr. Andrew Huberman here.

How Does It Work?

The SunSeek app uses your phone location to determine your coordinates in real time and shows you where to position yourself to see the sun.

Once your body is positioned in the direction of the sun, the DLE (daily light exposure) timer will activate. It is generally recommended to get at least 15-30 minutes of DLE, ideally in the morning.


Daily light exposure has a range of benefits such as:

  • Enhanced Mood: Daily light exposure, particularly in the morning, can stimulate the production of serotonin, a hormone that boosts mood and promotes a sense of calm and focus.

  • Improved Sleep Quality: Exposure to natural light during the day aids in regulating your body's circadian rhythm, promoting better sleep quality by helping your body properly produce melatonin, the sleep hormone, at night.

  • Immune System Boost: Sunlight triggers the skin's production of vitamin D, which is vital for maintaining a healthy immune system and can aid in preventing a variety of diseases.
