When I first heard of Huberman Lab during the pandemic, I honestly didn’t pay much attention (big mistake).

About a year later and after some big life changes, I decided to start taking my sleep seriously and followed Andrew Huberman’s research on sleep extensively. I tried to perfect my sleep to a T. And once I did, I regretted not starting earlier. Changing my sleep habits alone improved my mental health and focus more drastically than a regular meditation practice I’d kept up for years or consistent exercise.

Huberman’s recommendations are straightforward too. The basics of it are:

  1. get morning light within the first 1-3 hours of waking, aim for about 100,000 lumens, don’t wear sunglasses/hats, safely expose your eyes to light.
  2. get afternoon light around sunset, the same rules apply.

Simple enough, right?

After trial and error for a few months, I kept running into the same issues that prevented me from staying consistent.

  1. MORNING ISSUE: I had no idea how long to stay outside because different weather forecasts did not correspond to a set number of lumens of light. Sometimes, overcast days had 50,000 lumens, but a sunny day only had 23,000 lumens. I had to fumble around on my phone for the Light Meter App every morning to do quick maths. Not fun when you’re just rolling out of bed.
  2. AFTERNOON ISSUE: I skipped my sunset walks 85% of the time because I was busy doing something else on my laptop and didn’t know when the sun was setting. Without a pre-established amount of time that I knew I had to stay outside ahead of time, I couldn’t plan ahead, and would let whatever else it was I was doing take priority until it was already dark.

The morning issue was a hassle but at least I went on the walk.

The afternoon walk was the one I kept skimping on.

So, I built this to solve my problem. Or at least one of them. My wish is that it’s helpful for all the other Huberman followers (mega-fans) out there too.

What this app does is solve the issue of maintaining your afternoon sun exposure:
