Sleep Research is becoming a big thing these days. While you sleep, your brain stays busy, looking a wide variety of biological maintenance that prepares you for the day ahead.
We spend about 8 hours/day, 56 hours/week, 240 hours/month and 2,920 hours/year sleeping. And that's 1/3 of our lives.
Either we sleep too much or we sleep too little. There are many things, which seem more interesting or important than getting a few more hours of sleep. But just like exercise and nutrition are important in life, so is sleep.
Sleep is a periodic, natural, reversible loss of consciousness that might have served an adaptive role in our ancestors' survival. The quality of your sleep directly affects the quality of your waking life.
Sleep helps us restore and repair brain tissue by giving resting neurons time to heal. Including your mental sharpness, productivity, emotional balance, creativity, physical vitality, and even your weight. Sleep also enhances memory. During REM sleep, the stage of the sleep cycle during which vivid dreams commonly occur, we sift, sort, and file the day's experiences in our memory.
It also promotes creative thinking. During deep sleep, the pituitary gland is found to release a growth hormone.
The amount of time spent sleeping is genetically influenced. In the long run, sleep deprivation may contribute to obesity, hypertension, and memory impairment.
So when someone says let me sleep on it, let them.
