Sleep loss and accumulated sleep debt can impair our physical performance, particularly when there is a strong cognitive component associated to the activity. However, its impact is dependent on a variety of factors including individual variability, the type of training and sport as well as training familiarity and habit.
Insufficient sleep is most commonly a result of a late bedtime and/or early wake time, or difficulties falling asleep or staying asleep throughout the night. Although one or two hours of sleep loss may not appear to be significant, there is an cumulative effect when repeated each night which can lead to devastating effects on our performance, our health, our waistline and much more.
