Sleep science

Articles grounded in sleep-medicine and sleep-psychology sources — not symbol interpretation, but what research actually says about what happens to your body while you sleep.

• Sleep bruxism: why we grind or clench our teeth while asleep

  What sleep bruxism is, why it happens during certain stages of rest, its real link to stress, and what to actually do about it — grounded in sleep-medicine sources, not dream interpretation.

• Insomnia: why falling or staying asleep gets hard, and what the science says

  What insomnia actually is by real clinical criteria, why it takes hold and persists, its link to anxiety, and what to do about it — grounded in sleep-medicine sources, not dream interpretation.

• Sleep apnea: what obstructive sleep apnea is and why it interrupts breathing during sleep

  What obstructive sleep apnea is, why the airway collapses during rest, its real cardiovascular health risks, and what to actually do about it — grounded in sleep-medicine sources, not dream interpretation.

• Sleep hygiene: the daily habits that actually have scientific backing

  What sleep hygiene actually is, why it works physiologically, where it falls short on its own, and what to do about it — grounded in sleep-medicine sources, not generic advice.

• Sleep paralysis: why you wake up unable to move (and why it isn't dangerous)

  What sleep paralysis is according to sleep medicine, why the brain wakes before the body, where the 'presence' and chest-pressure hallucinations come from, and when it's worth seeing a doctor — grounded in scientific sources, not dream interpretation.

• Melatonin: what it is, what the evidence really says, and what gets overclaimed

  Melatonin is not a sleeping pill: it's the hormonal signal of night. What effect it actually has on sleep according to meta-analyses, where it genuinely shines, and the misconceptions about dose, timing, and regulation — grounded in chronobiology sources, not supplement marketing.

• Napping: what science says about how long it should last and when to avoid it

  Why the afternoon dip is physiological and not just the meal's fault, how many minutes of napping deliver a benefit without sleep grogginess, what NASA found with its pilots, and when napping works against you — grounded in sleep-medicine sources, not folklore.

• Screens and sleep: what the evidence actually says (and what's overblown)

  Screen light and the content you consume affect sleep through different mechanisms, and it pays not to conflate them: one is physiological and modest, the other behavioral and often bigger. No tech panic — real sources.
