Bingeing on your favorite shows
Calling all House of Cards fans—your love for TV marathons may chip away at your brain. According to a study published in a 2016 issue of Neurology, a lack of physical activity during middle age has been linked to a smaller mind later in life. “We found a direct correlation in our study between poor fitness and brain volume decades later, which indicates accelerated brain aging,” said study author Nicole Spartano, PhD, with Boston University School of Medicine in Boston. Similar research recently published in JAMA Psychiatry discovered that large amounts of television viewing and low physical activity in early adulthood were associated with a decline in cognitive function during midlife. On the other hand, these weird brain exercises might make you sharper.
Depriving yourself of sleep
Beauty sleep is a real thing, according to science. Physician-scientists at University Hospitals Case Medical Center gathered 60 women between the ages of 30 and 49; half of the volunteers fell into the “poor quality sleep” category. The ladies who snagged less slumber showed increased signs of skin aging, including fine lines, uneven pigmentation, slackening of skin, and reduced elasticity. “Our study is the first to conclusively demonstrate that inadequate sleep is correlated with reduced skin health and accelerated skin aging,” said lead study investigator Elma Baron, MD, associate professor of dermatology at Case Western Reserve University School of Medicine. These are the morning routines of people with great skin.
