An hour in a hyperbaric chamber oxygenates cells more efficiently than sucking on a bicycle pump or planting a fern in one's lung. Form a hydrogen bond with today's Groupon: for $35, you get one hour of hyperbaric oxygen therapy at Utah Sports and Wellness (a $100 value).

At Utah Sports and Wellness, Doctor Michael Cerami, who has more than 20 years' experience treating professional and amateur athletes, and his staff help to improve patients' general health and athletic-performance issues through hyperbaric oxygen therapy, a service designed to reduce muscle fatigue and encourage healing. The one-hour oxygen jolt can help athletes recovering from acute injuries, patients with chronic injuries or health issues, or children engaged in marathon bouts of breath-holding. After reclining in the deflated, enclosed chamber, patients give fingers a leisurely stroll on a provided iPad as technicians pump in filtered ambient air, which results in an increase of pressure equivalent to 11 feet below sea level or a stern glance by Rocky Balboa. This intensified pressure allows blood cells, plasma, and body fluids to absorb additional oxygen, thereby increasing the amount of oxygen that travels to organs, tissue, glands, and elsewhere. The increase of oxygen and pressure helps to decrease swelling and inflammation. After an oxygen-rich session, patients report feeling energized, refreshed, and more likely to engage houseplants in friendly banter.

While in the chamber, O2 hounds may experience pressure in the ears, which can be eliminated by following a few tips, such as giving an exaggerated yawn or a quick chorus of "The Song That Doesn't End." The treatment is not recommended for patients suffering from congestion or inner-ear problems. Though the chamber is completely sealed, it is possible for patients to communicate with technicians, loved ones, or beloved technicians from inside the pressurized interior.
