Light and circadian rhythm

10+ minutes of morning sunlight, dim lights in the evening, and amber bulbs after sunset anchor circadian rhythm and improve sleep onset.

Temperature, food, alcohol

Bedroom 65–68°F, last meal 2–3 hours before bed, alcohol capped 3 hours before bed. These three change sleep architecture more than any pill.

Supplements that help

Magnesium glycinate 200–400 mg, l-theanine 100–200 mg, glycine 3 g, and occasional low-dose melatonin (0.3–0.5 mg) for circadian resets. Skip high-dose melatonin.

Frequently asked questions

Is melatonin safe long term?
Low-dose (0.3–0.5 mg) is well-tolerated. High-dose (5–10 mg) is over-supplementation and can disrupt your own production.
Will magnesium make me drowsy?
It supports sleep onset and depth without strong sedation in most men.
