Why Cold Water Is Hot

Cold water has gotten a rather chilly reception in the United States, where it is mostly sought after as an antidote to a hot day. We love slipping into a cool blue pool when the mercury rises, or dipping our toes in the cold ocean. An icy mountain stream is okay for bathing if we're camping, but hot water is always our first choice for cleanliness, comfort, and health. Hot water relaxes and soothes. Cold water is a rude awakening, a shock to the system that we would rather avoid.

Other cultures around the world have used cold water as a 'shock to the system' to flush the organs and energize the body since ancient times. Scandinavian countries are famous for their dry-hot-sauna-roll-in-the-snow (or jump in a lake) routine, which the Finns were doing a thousand years ago. The Romans and Ottomans used cooling rooms after hot baths two thousand years ago in one of the largest social spa settings in the world. Traditional Chinese medicine has used cold water in healing therapies for even longer.

"Cold water is a stimulus," says Anne Bramham, founder of the American Spa Therapy Education & Certification Council, which trains spa industry providers in the physiology and science of spa therapies. "The use of all hydrotherapy is to manipulate circulation to improve our quality of life."
The man most closely identified with promoting cold water therapy in the (relatively) modern Western world is Sebastian Kneipp, a German priest who was pronounced terminally ill with lung disease when he was a young man in the 1800s. His self-treatment included daily baths in the icy Danube River for just a few minutes. After a year he was cured. He developed a system of self-care that involves more than hydrotherapy, but his treatments of alternating hot and cold water therapies have since been employed for many different health complaints. Bad Woerishofen (near Munich), where he lived, grew into a famous spa center. Today the Kneipp Association has a network of treatment and training centers throughout Europe and in South Africa.

Cold showers and immersions have been credited with increasing circulation by bringing blood to the capillaries, strengthening the parasympathetic a
nd sympathetic nervous systems, contracting muscles in a kind of simulated massage that helps eliminate toxins, and strengthening mucous membranes that help resist hay fever, allergies, colds, and coughs.

"The skin and nervous system interact to boost the immune system," says Bramham. But timing is everything, Bramham points out. And more is not better. "It's not an endurance test. The second you're in cold water, receptors are working and firing to the nervous system." The body responds more quickly to water temperature than air temperature and there are more cold receptors on the skin than heat receptors. It only takes 30-45 seconds of exposure to benefit from the effects of cold water. "Always finish cold," says Bramham. "And then wrap up and rest until your pulse rate and body temperature returns to normal. The effects on stress are amazing."

Canadians have also embraced thermotherapy, also called Nordic Spa, slowly heating the body up and then quickly cooling it with a swift, cold plunge, and many spas above the border offer bains chaud-froid, or hot-cold baths. With so much respect for the benefits of cold water therapy in other parts of the world, why hasn't it caught on before in the United States? "We want to take a pill to be healthy," says Mimi Barre, owner of International Skin and Body Care in Redlands, California, and a certified Kneipp therapist. "It's a remarkable way to get healthy and stay healthy but seems too weird by our standards because Americans don't like to do anything the least bit uncomfortable. We will eventually catch up," says Barre, who offers a Scotch Hose Galien Jet water treatment, where the body is sprayed with a strong stream of alternating hot and cold water. "But the treatments have to be presented as fun rather than healthy."

Leave it to Las Vegas to make cold water hot. Qua Baths and Spa opened in October 2006 at Caesars Palace with an Arctic Ice Room (55 degrees, heated benches), where artificial snow falls from a glass ceiling with 120 waving fiber optic lights, a shaved ice fountain provides crushed chips to cool the skin, and the air, lit by 25,000 iridescent blue glass mosaic tiles, is infused with mint. Qua has also copied the Roman bath concept, offering a tepidarium (98 degrees), caldarium (104 degrees), and frigidarium (56 degrees) for alternating water therapies.

Spa Montage in Laguna Beach offers The Art of Spa, alternating hot and cold experiences, with a cold plunge pool that (at 51 degrees) stimulates everything from the tips of your toes to your hair roots. Their Botanical Bath service includes iced peppermint towels for the forehead and feet, a soak in rose and bergamot-scented warm water, as well as the use of both hot and cold stones for the Toning Facial. A sixty-minute complimentary ocean walk invigorates in the morning with thigh-high cold water stork-walking along the shoreline.

While the health benefits of cold water therapies and alternating hot-cold immersions are vast, the truth is that it is almost impossible to endure cold water without laughing, screaming, or cursing. I laugh and scream, whether I'm counting out my 30 to 60 seconds in the shower at home, or doing the plunge pool routine. Cold water is a thrill, and that's hot.
