(Tip 12 of 21 biohacking tips)

😵‍💫 Tired, but wired? You might want to blame the light.

In the world of biohacking, we talk a lot about optimizing our bodies for better energy, focus, and sleep. And one of the most overlooked sleep disruptors?
👉 Blue light.

Blue light (the kind coming from your phone, laptop, and TV screens) can suppress melatonin—your sleep hormone—and trick your brain into thinking it’s still daytime.
That’s why even when you’re exhausted, your mind might still be racing at 11 p.m. 😵‍💫

In my last post, I shared a simple sleep rule:
📵 Screens off 1 hour before bed.
But hey—real life happens. Sometimes you need to check something late, finish a task, little bit of Netflix – I get it.

✨ That’s where blue light blocking glasses come in.

I personally use them every evening starting at 20:00, and it’s made a huge difference in how quickly I fall asleep and how deeply I rest.
My go-to brand? Lichtblock.
They’re stylish, effective, and specifically designed to block the most disruptive wavelengths of blue light that mess with your melatonin.

So here’s your new bedtime biohack checklist:

1. 🛏️ Wind down without screens when you can
2. 📵 Set a screen curfew (1 hour before sleep is ideal)
3. 👓 Put on your blue light blocking glass after 20:00

These tiny changes add up to big wins: deeper sleep, better energy the next day, and a happier nervous system. Your future self will thank you. 💛

Do you use blue blockers already, or thinking about trying them? Let me know—I’m always curious what works for others too! 👇

With love,
