Asthma is reversible airway obstruction and COPD is irreversible airway obstruction. Sudden exposure to cold, humidity, pollution at lower levels in atmosphere can precipitate asthma in susceptible individuals. Winter is the time to increase the dose of asthma medicines.
An attack of asthma is due to inflammation, narrowing and collection of fluid in the wind pipe and needs medicines to widen the wind pipe and reduce the inflammation.
The need of asthma medicines can be intermittent and/or permanent. The ‘Formula of ‘2’t becomes handy in such situations. A person who consumes more than two canisters of inhalers in a year or consumes asthma medicines more than twice in the night time in a month or more than twice in a day in a week, then he or she needs continuous asthma and anti inflammatory medicines. Inhalers are the best choices.
