We tried glycine, magnesium and chamomile tea. But her sleep still wasn't improving.
So we went back to basics.
What do caffeine and late-night phone use do to your sleep?
Caffeine: It blocks adenosine, a chemical that builds up sleep pressure throughout the day. Because caffeine can stay in your system for hours, an afternoon coffee may make it harder to fall asleep or affect sleep quality.
Late-night phone use: Bright light, especially blue-enriched light, can delay melatonin release. Scrolling, notifications and stimulating content can also keep your brain alert and push bedtime later.
We made two changes:
• Coffee only before 12 PM.
• No phone after 10 PM.
Her sleep improved, and her deep sleep reading on her tracker increased too.
Sometimes, before adding another supplement, look at the habits that might be working against your sleep.
Small wins. Big healing.
