Getting enough sleep is a big issue for a lot of people, and it only gets worse as we age.
In a study published in Neuron, a group of U.C. Berkeley researchers argue that certain brain mechanisms change as we age, and that prevents us from getting the right amount of sleep. Basically, as you age, your brain has more difficulty discerning when you're actually tired. The decline begins in your late 20s, and by the time you're 50, you spend half as much time in deep sleep than you did 30 years before. Not cool, brain!
"It's almost like a radio antenna that's weak," U.C. Berkeley professor of neuroscience and psychology, and the review's co-author Matthew Walker, said. "The signal is there, but the antenna just can't pick it up."
