The cellphone habit that may doom you to Alzheimer’s

Many studies have raised questions about the safety of cellphones. And now a study in California shows that there’s one thing you should never do with your cellphone if you want your brain to stay healthy.

The bad habit: Sleeping with your cellphone nearby and letting it disturb your sleep.

A study at the California Pacific Medical Center Research Institute (CPMCRI) in San Francisco shows that fragmented sleep and what the researchers call “lower sleep efficiency” were linked to a 40 to 50 percent increase in the chances of having serious memory and learning problems over the course of the 4-year study.

The research involved more than 2,800 older men who had a mean age of 76 years.

“It was the quality of sleep that predicted future cognitive decline in this study, not the quantity,” says researcher Terri Blackwell. “With the rate of cognitive impairment increasing and the high prevalence of sleep problems in the elderly, it is important to determine prospective associations with sleep and cognitive decline.”

For better sleep, you should bed down in a completely dark, quiet room without your cellphone or other electronic disturbers. Some experts recommend dimming the lights in your house about an hour or so before bedtime to help with sleep.
