HEALTHY LIVING Deep Sleep May THE LATEST RESEARCH
Alleviate Alzheimer’s Memory Loss
POOR SLEEP BOOSTS ASTHMA RISK A nine-year study of 455,405 men and women, published in BMJ Open Respiratory Research, found that poor-quality sleep doubled the risk for asthma. Those with the highest genetic risk combined with poor sleep patterns were 122% more likely to develop asthma than those with both a healthy sleep pattern and a low genetic risk. Researchers suggested that spotting and treating sleep disorders early might lessen the risk of asthma, regardless of genetic predisposition.
D
eep sleep, also known as non- REM slow-wave sleep, can act as
a “cognitive reserve factor” that may increase resistance to the buildup of beta-amyloid in the brain. Even with high levels of beta-amyloid, a protein associated with Alzheimer’s disease, researchers at the University of California, Berkeley, found that optimal amounts of deep sleep can be protective. The
researchers speculate that deep sleep salvages memory in people with brain disease. “People should be aware that, despite having a certain level of pathology, there are certain lifestyle factors that will help moderate and decrease the eff ects,” said Zsofi a Zavecz, Ph.D. The National Sleep Foundation recommends seven to eight hours of sleep for older adults.
Sleep Problems Increase Stroke Odds S
leeping for too few or too many hours, snoring, taking long naps, snorting, tossing and turning, waking during the night, and sleep apnea increase your risk
for having a stroke, according to a study published in the medical journal Neurology. The study of nearly 5,000 people found that those who snored had almost twice the risk of having a stroke compared to those who did not, and sleep apnea tripled the risk. “Having more than five of these symptoms may lead to five times the risk of stroke compared to those who do not have any sleep problems,” said Christine McCarthy, M.D.

MENTAL HEALTH: MARIJUANA USE LINKED TO SCHIZOPHRENIA Young men who are unable to stop
using cannabis, a condition called cannabis use disorder, have an increased risk of developing schizophrenia. Research published in Psychological Medicine found that as many as 30% of cases of schizophrenia among men ages 21 to 30 were caused by cannabis use disorder. Increased potency of cannabis may be responsible for the surge.
DEMENTIA: INTERNET USE PROTECTIVE Researchers followed dementia-free adults aged 50 to 64.9 years for a median of 7.9 years and found that those who regularly surfed the net had approximately half the risk of dementia compared to those who weren’t regular users, according to a study published in the Journal of the American Geriatrics Society. “Online engagement may help to develop and maintain cognitive reserve, which can in turn compensate for brain aging and reduce the risk of dementia,” said Virginia W. Chang, M.D., Ph.D., of New York University.
EXERCISE: CANCER-DESTROYING IMMUNE CELLS INCREASE Two studies from Finland’s University
of Turku found that short bouts of light or moderate exercise — even 10 minutes on a bicycle — can increase the number of immune cells in the bloodstream of cancer patients. In lymphoma patients, exercise increased the number of T cells, a type of white blood cell that helps the body fight disease. In breast cancer patients, exercise increased T cells as well as other types of helpful white blood cells, such as B cells.
HEART: LONG-TERM BETA BLOCKERS QUESTIONED Beta blockers are routinely prescribed
to heart attack survivors to lower the risk of another attack and to help prevent other cardiovascular complications. But a study published in Heart found no significant diff erence in cardiovascular outcomes between patients taking beta blockers more than a year after their heart attack and those who did not, unless they had heart failure or left ventricular systolic dysfunction.
