Mother Knows Best
Mom deserves a lot more credit than we give her. Here are 10 things that she got right.
Eyes and Ears continued...
"Was Mom right when she said not to strain your eyes? Maybe
a little," Karla Zadnick, OD, PhD, an associate professor of optometry at
Ohio State University in Columbus, tells WebMD. Her research shows a modest
link between close work and nearsightedness, "but certainly not enough to
suggest that we should stop kids from reading," she says.
Inherited causes of nearsightedness are far more important,
Zadnick says. Having one nearsighted parent increases the risk of this vision
problem threefold, while children of two nearsighted parents have seven times
As of this writing, WebMD was unable to confirm Mom's warning
that masturbation causes blindness. Sorry, Mom.
"Turn down that loud music!" Sound familiar? A recent
study showed that young disco patrons in Singapore suffered measurable hearing
loss, and the researchers recommended avoiding loud discos or at least visiting
them less often.
Although we might not have appreciated it at the time, maybe we
should thank Mother for telling us to say our bedtime prayers and for taking us
"Religion may be at least as good for the body as it is for
the soul," radiologist Andrew B. Newberg, MD, writes in his book Why God
Won't Go Away.
Many studies have supported this idea, including one from Duke
University that followed nearly 4,000 older adults. Even after accounting for
health conditions and medical care, older adults attending religious services
at least once a week lived longer than those attending less often.
"Religiously or spiritually active people have longer
lives," agrees Michael E. McCullough, PhD, an associate professor of
psychology at Southern Methodist University in Dallas.
That makes sense because religion discourages high-risk
behavior like involvement in crime, extramarital sex, and use of alcohol,
drugs, and tobacco. And it encourages marriage, which has health benefits of
its own. But over and above these effects, religion was linked to longer life
in 42 clinical studies that McCullough analyzed.
Remember when you wanted to pull an all-nighter getting ready
for the big exam, while Mom told you to get a good night's sleep?
"For at least some kinds of learning, good sleep after you
are initially exposed to the material is absolutely critical," Robert
Stickgold, PhD, an assistant professor of psychiatry at Harvard Medical School,
College students who stay up all night after studying
"completely wiped out the potential benefits of their training
session," Stickgold says. "Subsequent nights of sleep could not make up
for this loss."
Sleep deprivation also causes irritability, dangerous driving,
and careless mistakes, all of which can be hazardous to your health.
Mom said, "Just say no," and for good reason. Each year, illegal
drugs cause about 10,000 deaths in the U.S., and drunk driving kills another
16,000. Tobacco-related disease, including heart disease and cancers, kills
450,000 Americans each year. About half of smokers die young, cutting as many
as 25 years off their life span. Need we say more?
