183: Bastian Groiss - Scheduling Your Day Using Circadian Biological Timing

Indoor light is so deprived of the regenerative, repairing light frequencies that it’s almost impossible to be healthy, energized, or happy without going outside. - Bastian Groiss Share on X

What are the best times to wake up, eat, work out, focus, and sleep according to circadian biology? There’s an app for that!

I’ve been a fan of the Circadian app ever since I started experimenting with circadian rhythm optimization. It uses your location to align your daily activities with circadian biological timing.

So I spoke with Bastian Groiss, the director & co-founder of Circadian, about how technology can help us apply the science of circadian rhythms in the modern world.

Bright LEDs spike cortisol, adrenaline, & make us more productive during the day. But this overproduction of stress hormones leads to burnout. - Bastian Groiss Share on X

We discuss the evolutionary relationship humans have with sunlight. We also dive into how different sunlight stages impact everything from our energy levels and moods to our mental performance and overall well-being.
