Hot liquids relieve nasal congestion, prevent dehydration, and soothe the uncomfortably inflamed membranes that line your nose and throat. If you're so congested that you can't sleep at night, try a hot toddy, an age-old remedy. Make a cup of hot herbal tea. Add one teaspoon of honey and one small shot (about 1 ounce) of whiskey or bourbon. Limit yourself to one. Too much alcohol will inflame the membranes and make you feel worse.
This natural sweetener may work just as well for a cough as over-the-counter medicines. That could be especially helpful for children who aren’t old enough to take those. But don’t give it to an infant or a toddler younger than 1. There’s a small risk of a rare but serious kind of food poisoning that could be dangerous for them. And while you may have heard that “local” honey can help with allergies, studies don’t back that up.
