How H2O Works for You

Listen to It

Doesn't it seem that you can literally feel your blood pressure plummet during a day at the beach? It's not just the soothing sensation of sinking tired toes into warm sand: The sound of the surf may be part of what's calming you down. Researchers at the Huntsville (Alabama) Hospital tested the effect of ocean sounds on patients by playing these sounds for three consecutive nights. Another group of patients received the same care but no ocean sounds. The ocean group subsequently reported better quality of sleep, fewer awakenings, and deeper sleep overall.

The steady rhythm of breaking waves or the even roar of running water may be why it's so soothing. Our brains respond positively to repetitive sound, according to David Swanson, PsyD, a clinical psychologist in Los Angeles. For example, "if you're at the beach, the waves come in sets and have a consistent rhythm, so it's relaxing," Dr. Swanson adds. For instant indoor stress relief, try listening to a CD of natural water sounds or a tabletop fountain.
