In the past, sleep experts had warned us about exercising too close to bed time. They said excitement hormones such as adrenaline, which rise during exercise to give us energy and take about three hours to fall back to normal levels, would interfere with a good night’s sleep.
However, recent studies show this is not the case! These studies indicate that the timing of your exercise has no impact on your quality or quantity of sleep. This research is backed by a survey released by the National Sleep Foundation (NSF) which makes the case for exercising to improve sleep, regardless of the time of day or night. The survey polled vigorous exercisers who, whether exercising first thing in the morning or right before bed, were twice as likely as sedentary people to report they had a good night’s sleep every night or almost every night the week before. Therefore, the NSF has amended its recommendation for normal sleepers to encourage exercise at any time of day or night.
This is wonderful news for shift workers who often find it difficult to get to sleep and to fit exercise into their schedule. To learn more about this new information, go to the National Sleep Foundation’s website.
