Several studies have provided opposing results regarding afternoon napping – some indicate that it promotes cognitive function, whereas others produced contradicting results.

No one can stay awake forever. While we’re awake, our need for sleep gradually increases. If we deprive ourselves of sleep, our brain functions – such as attention and judgement – are impaired, and sleep becomes unavoidable.

No matter whether we are on a couch or at work – if we ignore our need for sleep, we ultimately crash. Video43s
