The risks of swimming Swimming is generally a healthy activity and enjoys a low risk of injury compared with many other sports. Nevertheless there are some health risks with swimming, including the following: Drowning, inhalation of water arising from Adverse water conditions swamping or overwhelming the swimmer or causing water inhalation. Actions of others pushing under water accidentally in play or intentionally. Exhaustion or unconsciousness. Incapacitation through shallow water blackout, heart attacks, carotid sinus syncope or stroke. Adverse effects of immersion Secondary drowning, where inhaled salt water creates a foam in the lungs that restricts breathing. Salt water aspiration syndrome, SWAS. Thermal shock after jumping into water can cause the heart to stop. Exostosis which is an abnormal growth in the ear canal due to the frequent, long-term splashing of water into the ear canal. (Known as Surfers ear) Exposure to chemicals Disinfectant Chlorine will increase the pH of the water, if uncorrected the raised pH may cause eye or skin irritations [6]. Chlorine inhalation; breathing small quantities of chlorine gas from the water surface whilst swimming for long periods of time may have an adverse effect on the lungs, particularly for asthmatics. This problem may be resolved by using a pool with better ventilation, with an outdoor pool having the best results. Chlorine also has a negative cosmetic effect after repeated long exposure stripping brown hair of all color, turning it very light blonde. Chlorine damages the structure of hair, turning it "frizzy." Chlorine can dissolve copper which turns blonde hair green. Proper pool maintenance can reduce the amount of copper in the water, while wetting the hair before entering a pool can help reduce the absorption of copper. Chlorine will often remain on skin in an anhydrous form, even after several washings. The
