A new study reveals that evening caffeine consumption can impact sleep quality by reducing slow-wave activity, even if sleep duration appears normal. Researchers used EEG to analyse brain activity during sleep, finding that caffeine can shift the brain towards a more wakeful state, hindering restorative sleep.
So the next time you're tempted to 'power through' on four hours of sleep or binge-watch one more episode, remember: Quality sleep is self-care -- and it's science-backed.
You may eat great food, exercise enough and yet not lose fat because you are sleep-deprived. Most of the magic takes place when you sleep well.
