🆓 Totally Free Biohacks
1. Catch Some Morning Rays ☀️

2. Make Your Bedroom a Sleep Cave 🌙
Dark. Cool. Quiet. That’s the vibe. Your brain makes more melatonin when it’s dark, and less when you’re scrolling TikTok in bed. Sleep like a champ by ditching the blue light and turning your room into a cozy bat cave 🦇

Your body sleeps best at cooler temps (60–67°F or 16–19°C). A cool room helps your core temp drop — exactly what your body wants to drift off into deep sleep 💤
