23 piecesEvery page answers one question, states what the research actually found, and says so when the answer is no. Sources are named at the foot of each piece.
Sleep
11 articlesWhy you wake, what actually shifts the night, and which habits have a trial behind them.
SleepWhy you wake up at 3am: when it's normal, when it isn'tYou run four to six cycles a night and can surface between them. Waking most nights for weeks, gasping, or three bathroom trips is a different signal.
SleepHow to fall asleep faster: what the guideline ranks firstGetting out of bed when you're frustrated is stimulus control, a graded AASM recommendation. Paradoxical intention, sold as proven, has insufficient data.
SleepCaffeine and sleep: the cut-off depends on your dosePooled trials put a 107 mg coffee at 8.8 hours before bed and a 217 mg pre-workout at 13.2. Half-life alone ranges from 2.3 to 9.9 hours between people.CBD guides
6 articlesWhat the trials measured — including the ones that found nothing.
CBD guideCBD and sleep: it is not the sedative the label impliesMost studies in one systematic review reported some benefit; 150 mg of pure cannabidiol nightly matched placebo on insomnia severity and time to drop off.
CBD guideHow much CBD to take: no established dose, only rangesSleep trials ran 25 mg to 300 mg an evening; retail labels start near 10–25 mg. The weight-based charts everywhere online have no trial behind them.
CBD guideCBD vs melatonin for sleep: neither is an insomnia fixAASM advises against melatonin for sleep onset or maintenance, backing timed doses only for circadian disorders. Cannabidiol at 150 mg matched placebo.Movement & recovery
6 articlesDesk pain, stiffness, and the doses that appear in real guidelines.
MovementNeck and back pain from sitting: it's not your postureWorkers prompted to take short breaks reported new trouble at 17%, against 44% left alone. Forward head position made no difference in 1,108 teenagers.
MovementDesk stretches: eight seated moves, and what they won't fixErgonomics guidance puts each hold at 10–20 seconds, three times an hour. A Cochrane review of 2,165 workers found relief only in data-entry staff.
MovementMovement breaks at work: five minutes every half hourWalking beat every break pattern on post-meal glucose (iAUC −11.8, P = 0.017), and all doses cut systolic pressure 4–5 mmHg. Caveat: 11 people, one day.
