In the pursuit of marginal gains, a better night of sleep will undoubtedly lead to a degree of better recovery and the chance of a better performance tomorrow.
Whilst the impact of marginal gains might not make too much difference to most of us wannabe athletes, improved sleep is one area where many of us could do better.
From personal experience, I know that family and work commitments stop me from getting as much sleep as I would like and that I don’t always feel great in the morning. After three months with Eight Sleep, I’ve found that I sleep a little bit less than previously BUT I feel a whole lot better and more refreshed in the mornings perhaps because I now normally have continuous sleep when previously it was disturbed.
