Did you know that your ears are always attentive to sound, even when you’re asleep? Unlike your eyes, your ears lack eyelids, which means they continuously process auditory stimuli. This constant awareness can have unexpected effects on your body, especially during sleep.
When your brain detects noise while you rest, it can instigate a mild stress response. This triggers your sympathetic nervous system, elevating cortisol levels and putting your body in a slight state of alertness. Over time, this persistent, low-grade stress can impact lipid metabolism, particularly affecting how your body processes and stores fats.
