Questions tagged [sleep]

Use this tag for questions about how sleep relates to physical fitness.

Sleep is distinguished from quiet wakefulness by a decreased ability to react to stimuli, and is more easily reversible than being in hibernation or a coma. Sleep is a heightened anabolic state, accentuating the growth and rejuvenation of the immune, nervous, skeletal and muscular systems. It is observed in all mammals, all birds, and many reptiles, amphibians, and fish.

Factors that impact the quality of sleep are often collected under the term "sleep hygiene", see for example the National Sleep Foundations tips.

Sleep longer the night after workout

I like to swim laps as it is not only healthy, but a sort of meditation. Most days, I will swim a mile or so late (because that's when the pool is open). I noticed that as I do this every day, I tend to need more sleep. Normally, I sleep around…

Increased weight from lack of sleep?

Over the last 2 weeks I went from 215 to 220 and the only significant change was a change in sleep habits, from a solid 8 to about 6 hours. Could sleep have that much of an impact?
