The old saying; ‘let a sleeping dog lie’ typically refers to muzzling a bad conversation, but in the literal sense, there are many reasons why we should let a sleeping dog lie.
Different Ways of Sleeping
Dogs sleep in a far different matter from humans, which explains in part why dogs need more sleep than a human. A human follows a binary sleep pattern.
- REM sleep. The REM sleep pattern yields the deepest sleep, allowing for the greatest rejuvenation of the body. A human will enter into REM sleep easier than a dog, and humans spend about 25% of their sleeping time in REM sleep. A dog only spends about 10% of its sleeping time in REM, which means the dog needs more hours of sleep for full rejuvenation of the body.
- Active patterns. A human spends much of his/her awake time in an active pattern, either in physical or mental stimulation. A dog meanwhile may only spend about 20% of its day truly active. Another 30% of the day may be spent in a waking pattern, but the dog is inactive.
