Well actually, kind of, says Colin, reassuring me that everyone has a bad night’s sleep from time to time, thanks to daily stressors. “Research suggests that we need to make up less than one third of the hours of sleep lost,” Colin says. “Furthermore, the sleep we get on 'recovery nights' may be deeper and more restorative. In other words, nature doesn’t let us down entirely but tries to play catch-up by making the most of the sleep we do get.” Top work, nature, top work.
