There are numerous suggested ways of countering the act of sneezing, although such proposed remedies are largely based on non-scientific suggestions as derived from personal experience or subjective preference. Examples of such alleged preventative techniques include the emptying of the air in the lungs that would otherwise be used in the act of sneezing through deep exhalation; holding in one's breath while counting to ten; staring up at a bright ceiling lamp; crinkling one's nose; among others.

Proven significant tips to reduce sneezing generally advocate reducing interaction with potential irritants, such as keeping pets out of the house to avoid animal dander; taking measures to ensure the timely and continuous removal of dirt and dust particles through proper housekeeping; replacing filters for furnaces and air-handling units; employing air filtration devices and humidifiers; and staying away from industrial and agricultural zones.
