Do you have a problem with mosquitoes? Drink a couple of spoonfuls of vinegar daily to fight off these unwanted pests. But do note, your perspiration will be unpleasant during the day you drink vinegar.
You can also add a tablespoon of apple cider vinegar to a quart of drinking water to repel mosquitos.
In both cases vinegar helps to deal with heat stress so you get double for your money!
