Habitual insufficient sleep is related to adverse outcomes related to cardiovascular, metabolic, mental, and immunological health. Robbins and her colleagues suggest that for healthy sleep, you get at least seven hours of sleep nightly, along with a consistent sleep routine, with the addition of naps when your sleep schedule falls short.Myth 2 One night of sleep deprivation will have lasting negative health consequencesWhile there are some negative effects, like worse performance in attention and stress on the cardiovascular system, youll recover if you catch up on your sleep.Myth 3 Taking naps in the afternoon is a good way to catch up on sleep if you have trouble sleeping at nightYes and no. While siestas are a cultural norm in some places, and naps are a good way to catch up on lost sleep from the night before, there are reasons not to nap. If you have insomnia, it could make it worse, for example. And habitual napping could be associated with adverse health outcomes. In other words, you dont want to become a daily napper.Myth 4 Watching TV is a good way to relax before sleepingTV-watching is most common amongst those who sleep for a short period of time. It also contributes to various difficulties with sleeping. Given that, researchers dont recommend TV as part of your nighttime pre-sleep relaxation routine.Myth 5 Your brain and body can learn to function just as well on less sleepWith restricted sleep, youll be tired for the first few days, and eventually, that tiredness will start to plateau.
