Re: Human sleep and recovery
Today I learned a bit about sleep inertia (that "morning" grogginess people get which may last from 10 mins to 2 hours!). I found it so interesting that how bad this "drunkenness" is depends on when in your sleep cycle you wake up.
When awoken from deep sleep, the sleeper feels groggy, tired and sometimes irritable. However, if someone wakes up from a lighter stage of sleep, they will feel more recharged, invigorated, energetic, and alert.
Furthermore it turns out coffee doesnt give you a jolt! The sleep inertia will go away by itself in the same amount of the time that it takes for the caffeine to "kick in"
