Can sleep be recovered?

It's one of the most frequently asked questions, and the short answer is no, not in the way we'd like. Sleeping little during the week and trying to compensate on Saturday doesn't allow the body to regenerate properly. Rest doesn't work like a bill that's paid off at the end: it works like a routine that's maintained. When the deficit becomes chronic, sleeping less than six hours consistently can lead to concrete consequences, such as hypertension and insulin resistance. At that point, sleep stops being just about energy and becomes about health.
