What in the heck causes salivary glands to suddenly go on overdrive?
When we don’t get enough water, our saliva glands work in overdrive to lubricate instead of using the water we’re drinking to keep us moist inside.* The overactive saliva glands can actually lead to a double chin because the glands are so overactive that they get weak and drop (under the chin) and voila, the double chin!* Hurry, DRINK UP so you don’t get that double chin!
