COLUMBIA, S.C. — If you’re not a sponge, you’re probably not a swimmer.
But if you are, you should be able to get by in a swimming pool.
The U.S. Centers for Disease Control and Prevention (CDC) and the U.K.’s National Health Service have released guidelines that outline the best swimming lessons for those who want to learn to swim without becoming drowning sponge.
The guidelines are based on a 2010 survey that showed that about half of Americans think they can swim without drowning, the CDC said.
In a report released Friday, the agencies said the survey found that more than 90 percent of the participants felt confident enough in their ability to swim safely and that nearly three-quarters of those who answered the survey believed they could swim without being overwhelmed.
Some swimming lessons require that participants sit or lie on a towel and are supported by a partner.
Other lessons require swimming in the water with a partner or other people who are nearby.
Most of the time, the guidelines state, participants can swim in and around the water, although there is some evidence that some people can swim safely in the air, where it is safer.
The CDC said it encourages everyone who is unsure of their swimming ability to take the CDC’s guidance to heart and use it as a starting point to learn about what works for them.
The U-shaped pool, designed by British architect John Burrows, was designed by an architect who is best known for his watercolor illustrations of the Titanic.
It is one of the largest swimming pools in the world and is the first of its kind in the United States.
The CDC recommended that all adults and children over 5 have access to it.
