LIMA, Peru — They arrive at Lima's coast shortly before dawn and wade into the Pacific Ocean, seeking relief from the ailments doctors have been unable to cure.
Some come in groups, jumping, laughing and running along the shore. Others bathe alone silently in the calm, gray sea.
Under overcast skies at Playa de Pescadores, or Fishermen's Beach, the bathers practice thalassotherapy, which derives from the Greek "thalasso," for "sea," and draws on the ocean's healing properties.
Most of the bathers practice an informal, self-directed sea therapy. Others work with leaders such as natural therapy promoter Jose Cusquisiban.
"The sea is the pharmacy of humanity," said Cusquisiban. "It has many minerals, vitamins."
He has his patients jog barefoot on the sand. "Then we make a harmonious circle of prayer. Afterward, we sing, we practice laugh therapy, we hug and finally we enter the sea and teach those who don't know how to swim," Cusquisiban said.
Other medical practitioners at the beach include chiropractor Felix Retamoso, who treats people for back problems.
Oswaldo Salaverry, an expert at Peru's National Institute of Health in intercultural medicine — the combination of native and Western medicine — said that "being in contact with the sea, with cleaner air, with a certain type of sand, can grant general health benefits."
