If you are sleep-deprived, and need a healthy siesta, careful planning is key
An afternoon nap is one of the joys of life, although excessive napping could signal all is not well. A new study, published in the journal Alzheimer’s & Dementia, suggests that napping during the day could be an early sign of Alzheimer’s. Researchers compared the postmortem brains of 13 people with Alzheimer’s to the brains of seven control subjects and found those with the brain disease had a build up of a protein, tau, in areas of the brain involved with wakefulness.
“Some people nap all their life, no problem,” Lea Grinberg, professor of neuropathology at the University of California San Francisco, told the Times. “In some cultures, people will have a daily siesta – this is fine. The warning comes when people start sleeping during the daytime, when they did not before.”
