Sleep paralysis is when you’re awake but can’t move or speak, typically as you’re falling asleep or waking up. It happens when your brain and body are out of sync during the transition between sleep and wakefulness, often linked to REM sleep, where your muscles are naturally paralyzed to prevent acting out dreams. Episodes are brief, lasting from seconds to a few minutes, and while scary, they’re not physically harmful.
The circadian rhythm helps your body stay in sync with the environment, optimizing energy and health. When disrupted—by irregular schedules, travel, or artificial light—it can cause sleep issues, fatigue, and even health problems like obesity or mood disorders.
Sleep is a universal need, but how we sleep can depend on where we live. A fascinating study, published as "Country differences in nocturnal sleep variability" (Study Source), explored how sleep patterns vary across 35 countries.
