IN Turkey, this figure is estimated not only by experienced travellers who have something to compare the Turkish waves. The Ministry of health of Antalya for 15 days conducts a regular inspection of samples of sea water in 360 points over 640 km of the coast. Sea water samples are taken from 1 May to 30 October according to the schedule of the Ministry of health. Water samples for analysis are delivered to the laboratory of Antalya and Alanya.

Warm and clean Mediterranean Sea is considered one of the most healing on the planet. The microelements contained in the sea waters – magnesium, sodium, potassium, chromium, iodine, bromine and others have a positive effect on the functioning of all systems of the human body. Swimming in sea water in Turkey will be useful both for the treatment and as a prevention of respiratory and digestive diseases, musculoskeletal system, heart and vascular problems, as well as skin diseases.
