Biohacking with Kate

(Tip 1 of 21 biohacking tips)

I’m kicking off this biohacking series with something so simple, it’s easy to overlook—and yet so powerful, it can truly transform your life. It’s free, it’s accessible, and I’ve been practicing it for years. That is : simple daily sunlight exposure.

I can vouch for its impact—not just on your health, but on how you show up in every role you play: as a colleague, a mom, a partner, a human.

Sunlight is the original biohack.

Getting outside every day—even when it’s cloudy—is one of the most effective, zero-cost ways to boost your mental and physical wellbeing. Natural light helps regulate your circadian rhythm, which means better sleep, more energy, and a brighter mood.

Even indirect exposure through your eyes and skin sends a powerful signal to your brain: It’s daytime—wake up, focus, thrive.

And while vitamin D gets all the spotlight, there’s more going on. Sunlight triggers the release of serotonin, the “feel-good” hormone that helps reduce anxiety and depression and improves your ability to concentrate.

So here’s your challenge:
Instead of reaching for your phone first thing, step outside for just 10 minutes. Let your body soak in the light. Let your brain recalibrate.

🌞 Try it for 30 days.
🌱 See how you feel.
💛 Become that more energized, focused, present version of yourself.

Are you in? Let’s do this—one sunbeam at a time.

With love,
Kate
