Muscle grows during rest: how many hours of sleep do you need to promote muscle development and recover better after training

Recent findings emphasize the critical role of sleep in physical fitness, noting that muscle growth and recovery are primarily facilitated during rest periods rather than during exercise itself. Adequate sleep duration is identified as a fundamental component of a training regimen, alongside nutrition and resistance training, as the body repairs tissue during these inactive phases.

Separately, research from the University of Toronto Mississauga published in PLOS One indicates that sharing a bed with a canine companion does not objectively impair human sleep quality or efficiency. While the study suggests that human rest remains stable, it notes that the sleep patterns of the dogs involved were affected by the proximity to their owners.
