5-HTP (5-hydroxytryptophan) is the direct chemical link between tryptophan and serotonin, one step closer to serotonin in the pathway than tryptophan itself, and it crosses into the brain more readily. That raises the same question we explored in Serotonin and Sleep: since serotonin’s well-established primary role is promoting wakefulness and inhibiting REM sleep, not sedating

Diphenhydramine, the active ingredient in Benadryl, Unisom SleepTabs, ZzzQuil, and most “PM” pain reliever formulations, is one of the most commonly used sleep aids in the US, despite not actually being recommended for regular sleep use by sleep medicine guidelines. The American Academy of Sleep Medicine’s 2017 clinical practice guideline recommends against using diphenhydramine for

You finish a week of investor calls, flights, late-night messages, and early starts with the same calculation: five short nights, one long Saturday, problem solved. Saturday arrives, you sleep deep into the morning, wake feeling heavy rather than restored, and then struggle to fall asleep at your usual time on Sunday. Monday begins with another

CBD and sleep are marketed together constantly, but the direct clinical research specifically on CBD and insomnia is thinner and more mixed than the marketing suggests. The most rigorous independent trial of pure CBD, 150 mg nightly for two weeks in adults with moderate-to-severe insomnia, found no significant difference from placebo on insomnia severity, sleep

The most popular advice about GABA dosage for sleep is also the least useful: take 300 mg before bed and expect the problem to solve itself. Human research doesn’t support that kind of universal prescription. Studies have tested different doses, formulations, populations, and sleep measurements, and the clearest pattern is that timing and consistent use

Many individuals use melatonin like a sleeping pill. They select a large tablet, swallow it right before bed, and believe a higher dose will produce deeper sleep. That approach overlooks the core point: melatonin is primarily a timing signal, and with a dose as low as 0.5 mg, timing often matters more than quantity. For

The popular advice is simple: have a nightcap, fall asleep faster, and wake refreshed. The first part can be true. The conclusion usually isn’t. Alcohol and insomnia are linked by a deceptive trade-off, because alcohol may make sleep onset feel easier while weakening the second half of the night, when stable, restorative sleep matters for

Melatonin and sleep are connected through a real, well-understood biological mechanism, melatonin is the hormone your pineal gland releases in response to darkness, signaling to your body that it’s time to wind down. Where it gets more complicated is exogenous, supplemental melatonin’s actual effectiveness as a general insomnia treatment. The American Academy of Sleep Medicine’s

Melatonin dosage research points to a clear pattern: for helping you fall asleep faster, effectiveness increases with dose up to roughly 3 to 5 mg per day, then plateaus, meaning the 10 mg tablets common on store shelves generally don’t work better than a well-dosed 3-5 mg product. For circadian purposes, like jet lag or

Healthy adults typically spend about 10% to 20% of total sleep time in deep sleep, or roughly 40 to 110 minutes during a seven- to nine-hour night. That range shifts significantly with age, and chasing a fixed number can be counterproductive. The popular advice usually sounds more precise than the evidence allows. A wearable reports
