Usually in public places in the city, each xangtimet air masses from 10-20 anion, inrooms from 40-50 anion/cm3, on the lawn or park anion/cm3 100-200, in Meanwhile on the coast up to 10,000 anion/cm3, more than hundred times higher than in the rooms.

The anion is the ions should have the effect of limiting bacterial proliferation. Anionenvironments will increase the capabilities of the sympathetic nervous people, makes people feel fresh cheerful, increased red blood cell.

Therefore, the air in coastal areas is very beneficial to human health. Most people feelthe air at the beach is clean, fresh breath, especially beneficial to those suffering fromanemia, pneumonia, hypertension, depression, asthma, ... This also the reason why therest camp was built much more on the coast.
