You can have your training, nutrition, supplements, and recovery dialed in and still overlook one of the most powerful inputs your body receives every day: light. From the moment you wake up to the screens, LEDs, office lighting, and nighttime exposure around you, your light environment may influence your circadian rhythm, recovery, sleep, and performance.

In this episode, Alex Kikel and I break down how different wavelengths of light interact with the body, why morning and evening light matter, and where red and near-infrared light may fit into a performance-focused routine. We also look at what you can do for free, what is worth spending money on, and where biohacking starts becoming unnecessary overkill. The goal is simple: understand the mechanism, control the basics first, and use technology only when it actually adds something.

What's Discussed:

(12:47) Why light should matter for performance and body composition.

(19:14) Blue light, near-infrared light, and what your environment is missing.

(23:48) The simplest light protocol you can do for free.

(34:15) How light fits into fat loss, muscle, and recovery.

(42:46) Why the first few minutes of your morning matter.

(54:20) Why sleep supplements cannot fix a bad nighttime environment.

(57:08) Using red and near-infrared light around your workouts.

(1:06:45) Red light for skin, hair, and recovery protocols.

(1:13:35) Light habits: overrated or underrated.

(1:17:28) The $0, $100, and $10,000 light protocol.

(1:20:29) Why jumping straight to expensive biohacks can backfire.
