Sleep Hygiene Habits for Deeper Rest: A Bedroom Reset
Twelve evidence-based habits that improve sleep quality — from light timing to magnesium glycinate — explained simply.
Light is your most powerful sleep cue
Get bright outdoor light within 30 minutes of waking — this anchors your circadian clock and makes melatonin release on time that night. After sunset, dim every light in your home to warm tones below eye level. Lamps, not overheads.
Temperature, sound and air
Core body temperature must drop 1-2°C to fall asleep. Cool the room to 16-18°C, take a warm shower 90 minutes before bed (the rebound cooling deepens sleep) and crack a window. White or brown noise masks irregular sounds that fragment sleep without your noticing.
Supplements that have actual evidence
Magnesium glycinate (200-400mg) for muscle relaxation and GABA support. Glycine (3g) reduces sleep latency. L-theanine (200mg) softens racing thoughts. Skip melatonin unless you're shifting time zones — chronic use blunts your own production.
The wind-down ritual
Phone out of the bedroom, replaced by a paper book or a journal. Two pages of free writing to clear mental tabs. Skin and body care done at the bathroom sink, not in bed. Lights out within 30 minutes of climbing under the covers.
