Lack of sleep and poor sleep quality are connected to diabetes, cardiovascular disease, premature death and abdominal obesity. Research proves regular weight lifting improves sleep quality.
A study from Appalachian State University in North Carolina discovered that weight training helped people get asleep faster and improved sleep quality. The time of their training (no matter if they trained in the morning, afternoon or evening) had no impact on their sleep structure or night-time blood pressure.
People need 6-8 hours of good-quality sleep a night for maintaining optimal health. Another study showed that lack of sleep deteriorates body functions, while getting enough sleep reduces risk of injury.
Researchers also suggest weight training could be particularly beneficial for improving sleep in people with psychological disorders and those with muscle or bone loss.
