Juice bars. Wine bars. Coffee bars. And now ... oxygen bars?
Yep, popping up all over the U.S. (as well as in Canada and Japan, where the
craze is thought to have begun because of the serious air pollution there),
oxygen bars sell "hits" of 40% oxygen that is delivered through a mask
worn over the face.
Proponents of this oxygen "therapy" say it boosts
energy levels, increases your endurance during exercise, helps you bounce back
more quickly from physical exertion, provides relief from stress and pollution,
increases your concentration, helps you relax, and eases headaches and

Hey, we all are. Hormones control just about every aspect of our physical
and mental health — and when they go off-kilter, they can trigger anything from
acne and insomnia to memory loss and weight gain. It's enough to ruin any
woman's day. Here, 6 common side effects of hormonal flux, plus how to balance
Kristi Huddleston, owner of O2Cool Oxygen Bar in Aventura,
Fla., fell in love with the treatment when she first tried it in Atlanta.
"It reinvigorated me," she says. "I wanted to share the feeling
At Huddleston's oxygen bar, customers can purchase sessions
that last anywhere from 5 to 20 minutes; monthly memberships are also
available. The oxygen that is breathed in is scented with the customer's choice
of aroma to enhance the experience, says Huddleston.
"Who doesn't like smelling something nice?" she
Huddleston is quick to point out that she is not making any
medical claims, and that customers are not allowed to receive any more than 30
minutes a day of the oxygen. She does say, however, that the oxygen relieves
her stress, and customers have told her it eases their migraines and their
Sounds great ... if that's true. The medical community doesn't
buy it, though. "There has been no scientific research that this extra shot
of pure oxygen has any benefits," says George Boyer, MD, chief of pulmonary
and critical care at Mercy Medical Center in Baltimore.
The Canadian Society of Respiratory Therapists has gone so far
as to issue a position statement that reads: "As health professionals, we
cannot ethically or morally support providing oxygen therapy to those who do
not require it."
Healthy individuals take in approximately 21% oxygen from the
air they breathe, says Boyer. At that level, blood is almost completely (99%)
saturated, meaning there is no need for additional oxygen.
"If you're healthy, you're already saturated," says
Eric Barnett, clinical director of Rancho Mirage Hyperbarics in Rancho Mirage,
Calif. "You're not going to be any more saturated just because you're
breathing in additional oxygen."
"For the vast majority of people, there is little harm"
says Boyer, "but also absolutely no science of benefit."
"If your lungs are healthy, and you have no breathing
difficulties, your body has all the oxygen it needs," says Boyer.
"Taking in more is like going to the gas station and trying to fill a tank
that's already filled."
In hospital settings, 100% oxygen may be delivered -- but even
then only on a short-term basis, says Boyer -- less than 24 hours and
preferably less than 12 hours. To breathe pure oxygen at that level for any
longer can have toxic results, including "shock lung," or adult
respiratory distress syndrome. In infants, too much pure oxygen for too long a
time can also lead to retinal problems as the blood vessels in their eyes won't
Since the oxygen provided in oxygen bars is only at a
concentration of 40%, visiting an oxygen bar probably won't cause you any
damage, says Boyer, unless you have certain disorders such as emphysema. Too
much oxygen can cause a person with emphysema to stop breathing.
