As sestas são boas para nós?

As sestas  à tarde são revigorantes — mas será que podem atrapalhar os nossos ciclos de sono? O cientista do sono Matt Walker revela os prós e os contras da sesta, além de dar dicas sobre como obter o máximo da nossa próxima sesta.

Humans often feel a noticeable dip in alertness between one and four in the afternoon, and science shows this is hardwired into our brains. Evidence suggests our bodies may be built for biphasic sleep: a long stretch at night paired with a short daytime nap, much like siesta cultures worldwide. While short naps can boost brain and body health, long or late naps can disrupt nighttime rest. People who struggle to sleep at night are better off skipping naps and building natural sleep pressure for bedtime.
