More than 11 million seniors in the U.S. experience falls each year-that’s one in every three people over age 65. These falls have many causes, including osteoporosis and neurological issues. The Archives of Internal Medicine recently reported new findings on another leading cause of falls: poor sleep. For older women, sleep deprivation can be even more hazardous. According to the Archives of Internal Medicine article, actigraphy measured sleep studies done to determine fall risk in older women demonstrated that sleep deprivation can lead to an actual slowing in motor reaction time, even when accounting for other factors, such as age or the use of benzodiazepines or other medications.
