Myth: breathing into a paper bag will ease hyperventilation
Reality: never breathe into a paper bag – it can cause dangerously low oxygen levels.
What to do: there are a lot of reasons why someone might hyperventilate (breathe fast), so you should calmly encourage them to breathe slowly and deeply. One trick is to ask them to hold his or her breath, then exhale and hold another breath. Repeat this exercise until he or she begins to relax.
