5 Ways Pets Can Improve Your Health
Owning a pet can ward off depression, lower blood pressure, and
boost immunity. It may even improve your social life.
By Jeanie Davis
A pet is certainly a great friend. After a difficult day, pet owners
quite literally feel the love.
In fact, for nearly 25 years, research has shown that living with
pets provides certain health benefits. Pets help lower blood
pressure and lessen anxiety. They boost our immunity. They can even
help you get dates.
Allergy Fighters
"The old thinking was that if your family had a pet, the children
were more likely to become allergic to the pet. And if you came from
an allergy-prone family, pets should be avoided," says researcher
James E. Gern, M.D., a pediatrician at the University of
Wisconsin-Madison, in the Journal of Allergy and Clinical
Immunology.
However, a growing number of studies have suggested that kids
growing up in a home with "furred animals" — whether it's a pet cat
or dog, or on a farm and exposed to large animals — will have less
risk of allergies and asthma, he tells WebMD.
In his recent study, Gern analyzed the blood of babies immediately
after birth and one year later. He was looking for evidence of an
allergic reaction, immunity changes, and for reactions to bacteria
in the environment.
If a dog lived in the home, infants were less likely to show
evidence of pet allergies — 19% vs. 33%. They also were less likely
to have eczema, a common allergy skin condition that causes red
patches and itching. In addition, they had higher levels of some
immune system chemicals — a sign of stronger immune system
activation.
"Dogs are dirty animals, and this suggests that babies who have
greater exposure to dirt and allergens have a stronger immune
system," Gern says.
Date Magnets
Dogs are great for making love connections. Forget Internet
matchmaking — a dog is a natural conversation starter.
This especially helps ease people out of social isolation or
shyness, Nadine Kaslow, Ph.D., professor of psychiatry and
behavioral sciences at Emory University in Atlanta, tells WebMD.
"People ask about breed, they watch the dog's tricks," Kaslow says.
"Sometimes the conversation stays at the 'dog level,' sometimes it
becomes a real social interchange."
Dogs for the Aged
"Studies have shown that Alzheimer's patients have fewer anxious
outbursts if there is an animal in the home," says Lynette Hart,
Ph.D., associate professor at the University of California at Davis
School of Veterinary Medicine.
"Their caregivers also feel less burdened when there is a pet,
particularly if it is a cat, which generally requires less care than
a dog," says Hart.
Walking a dog or just caring for a pet — for elderly people who are
able — can provide exercise and companionship. One insurance
company, Midland Life Insurance Company of Columbus, Ohio, asks
clients over age 75 if they have a pet as part of their medical
screening — which often helps tip the scales in their favor.
Good for Mind and Soul
Pet owners with AIDS are far less likely to suffer from depression
than those without pets. "The benefit is especially pronounced when
people are strongly attached to their pets," says researcher Judith
Siegel, Ph.D.
In one study, stockbrokers with high blood pressure who adopted a
cat or dog had lower blood pressure readings in stressful situations
than did people without pets.
People in stress mode get into a "state of disease," in which
harmful chemicals like cortisol and norepinephrine can negatively
affect the immune system, says Blair Justice, Ph.D., a psychology
professor at the University of Texas School of Public Health and
author of Who Gets Sick: How Beliefs, Moods, and Thoughts Affect
Your Health. Studies show a link between these chemicals and plaque
buildup in arteries, the red flag for heart disease, says Justice.
Like any enjoyable activity, playing with a dog can elevate levels
of serotonin and dopamine — nerve transmitters that are known to
have pleasurable and calming properties, he tells WebMD.
"People take drugs like heroin and cocaine to raise serotonin and
dopamine, but the healthy way to do it is to pet your dog, or hug
your spouse, watch sunsets, or get around something beautiful in
nature," says Justice, who recently hiked the Colorado Rockies with
his wife and two dogs.
Good for the Heart
Heart attack patients who have pets survive longer than those
without, according to several studies. Male pet owners have less
sign of heart disease — lower triglyceride and cholesterol levels —
than nonowners, researchers say.
