This simple habit can ensure that you’re drinking enough water. One in five kids and young adults reported not having a single drop on a given day, according to a JAMA Pediatrics report, and adults often don’t get enough either. Your body needs fluids to maintain proper functioning, and dehydration may lead to constipation, dizziness, confusion and low blood pressure.
SMART TRICK: Be sure to constantly refill your water bottle every hour. Purchasing a 9-ounce S'well insulated bottle, a GHI top pick, means you'll be able to measure your progress throughout the day (did you down it all before refilling? No? Time to drink up!).
