Avoid Injury and Drowning
- Swim only when lifeguards are on duty.
- Learn about the local water conditions, currents, and rules before entering the water.
- Use proper safety equipment such as lifejackets.
- Make sure your gear, such as scuba masks and tanks, are properly fitted and maintained.
- Never swim alone or in unfamiliar waters.
- DO NOT drink alcohol before or during swimming, diving, or boating. Alcohol affects balance, coordination, and judgment.
- DO NOT dive in shallow water. Always enter water feet first.
- Be aware of and avoid hidden obstacles in the water.
- Supervise children closely around water.
- Obey posted signs and warnings, and recognize that warnings may not always be present.
- Know the meaning of and obey warnings represented by colored beach flags. These may vary from one beach to another.
- Use experienced guides when boating, scuba diving, or participating in other water-related activities.
- Learn the risks associated with local sea animals, such as urchins, jellyfish, coral, and sea lice, before you get in or on the water.
- Watch for signs of rip currents (water moving quickly in a channel away from shore); if you are caught in a rip current, swim parallel to the shore until free, then swim diagonally toward the shore.
Avoid Germs in the Water
- Don’t swallow the water you are in or on.
- Don’t swim with open cuts, abrasions, or wounds. Breaks in the skin can let harmful germs into your body.
- Don’t swim if you have diarrhea.
- Don’t swim in cloudy water.
Be careful about swimming or wading in fresh water in some countries:
- Infections such as schistosomiasis and leptospirosis are spread by contact with fresh water.
- These microbes can penetrate your skin, so swallowing water isn’t necessary to cause infection.
- Avoid contact with any fresh water (lakes, rivers, streams) where these infections are a problem (see the destination pages for more information).
- Seek medical care if you think you have been exposed to a waterborne infection.
