Swimming has been shown to have dozens of health benefits. It can improve heart health, help prevent diseases, and even can improve your mood if done regularly. But if you are swimming in the wrong place at the wring time, it can have some serious health consequences. With the rise in frequency and strength of natural disasters we are seeing more and more coastal cities whose sewer systems are not able to handle a very sudden flash flood of water from the likes of a hurricane or tropical storm. This is causing their outdated sewer systems to back up and get mixed on with the storm water. This storm water then ends up flowing back into the ocean thus contaminating the water that so many beach goers enjoy each and every day. Swimmers that frequent this contaminated water could face some very serious health concerns. It is recommended that you wait a few days after the storm has passed as opposed to hitting the beaches the very next day. This gives the ocean enough time to naturally dilute the water through the shifting of tides and replacing it with fresher water. Dr. Stuart Khan, who is an expert in water quality testing and safety, further expands on the dangers of sewage flowing into the ocean after a major storm here. If we are going to protect vacationers and members of coastal communities, then cities must begin to seriously consider investing in upgrading their sewer systems so that these issues will not persist.
