Another supposed cure , what in the UK is called "an old wives tale" , you in US maybe call an urban myth , is sea air , go to the seaside , go for a walk along the promanade ( US boardwalk) till the sunsets , stay in a hotel , and with the the whiff of sea salt, faint cry of gulls , you drift off into a cozy bo bo ( what mums say to their baby , snooze ).
I can remember childhood holidays and this would happen .
Sea air is good for chest infections as well.
