I have always been taught to drink plenty of fluids. This one is easy. –Allison
“Staying hydrated is very important, especially when you’re sick and your throat is irritated or inflamed,” Dr. Linder says. “You should be drinking enough fluid so that your urine is light yellow or clear. This keeps your mucous membranes moist and better able to combat bacteria and irritants like allergens, and makes your body better able to fight back against other cold symptoms.”
What you drink is up to you, Linder adds. Water always works (ice cubes, too!), but you can also change it up with something slightly sugary, like a watered-down fruit juice, or something salty, like chicken broth.
