Coming up next on Forum, more and more Americans are sleeping less and less. That’s according to data from the Centers for Disease Control. It shows a growing number of people sleep less than six hours at night. And research shows people who sleep less are at greater risk for heart disease, obesity and diabetes. And the American Association of Pediatricians came out with a statement saying teens should start school later, it lighted the fact of not getting enough sleep. We’ll talk with experts about a whole range of sleep issues. That’s next after this.
It turns out that if you wake people in the laboratory and sample their dreams, in terms of their emotions, they tend to be equally positive and negative. However the reason that many of us think that our dreams are dominated by negative, the sort of experiences, is because they tend to be more memorable that when we wakeup. It’s the drams that negative that perhaps have woken us up and they are the ones that get in printed into our brain that we remember in that morning.
For alcohol does at least two bad things to your sleep. First, it fragments your sleep so you wakeup more frequently throughout the night. And second, alcohol is particularly a potent suppresser of your RAM sleep, that dream sleep that we spoke about. So what you are doing with alcohol before bed is simple sedating yourself. Sedation isn’t sleep. And so I think we can found those two things. So alcohol is an enemy of sleep.
