How learning about the circadian rhythm brought me, a non-practicing brother, back to never missing Fajr

A few months back, I was digging into the circadian rhythm and stumbled on something amazing. Even though I wasn't practicing, I noticed that the Islamic prayers line up perfectly with key points of the day-like natural 'time givers' (zeitgebers). Five prayers, five anchors for our internal clock. Fajr starts about an hour to an hour and a half before sunrise. It's this peaceful, crisp moment, almost magical, away from the daily rush. Experiencing it these past months got me back into writing. Then sunrise ends Fajr, and a wide arc begins until Dhuhr, which hits right at midday, solar noon-when the sun is highest and starts dipping west. Asr follows, with the sun's descent making long shadows in that soft golden light, until the shadows fade but the sky stays bright. That leads to Maghrib, a short window just over an hour, like Fajr. It's when the body starts releasing melatonin for sleep. Finally, Isha marks full night, a last chance to disconnect from life's noise and head to bed. This discovery pushed me to create a simple memo and notepad tool for these moments of light. Since then, I haven't missed a single Fajr-and I was a total night owl before. Now I really feel my rhythm syncing with the natural light. Alhamdulillah for that.
