5.1.2. Saline douches:
Nasal douching is cheap and safe, and an important part of the
management of both rhinitis and rhinosinusitis that do not interfere
with the WADA regulations. Especially in symptomatic athletes exposed to
irritants (swimmers, runners in polluted areas) this is a valuable
option. Since the WHO recommends to shower and clean off the chlorine
after exposure to a chlorinated swimming pool 65, it
seems logical to clean the nasal mucosa after swimming, although no data
are available on the action of nasal saline douchings in rhinitis
prevention.
