While side effects are infrequent, some people may experience a mild tickle in their throat or an increase in cough due to excess mucous buildup; an indication the salt therapy is working. Those with hypersensitive skin may also experience slight skin irritation.
Some people may be concerned about the intake of salt and its relation to diet, high blood pressure and hypertension; however the type of salt intake related to those items above is connected to the digestive tract, unlike dry salt therapy, which is associated with the respiratory system. When inhaled, the amount of micro-sized particles entering the respiratory system is extremely low and doesn't present any risk to your health. It actually kills bacteria, reduces inflammation and expands airways.
