The Best New Year's Resolution is to Drink Water

Take big steps in the right direction for emotional, physical, or mental health just by focusing on one thing — drinking more water

Pumpkin pie, turkey, stuffing and mashed potatoes. By New Year’s Eve, Thanksgiving and Holiday leftovers are long gone, and everyone is done counting their thanks. It’s at this point that people start making new resolutions, and for many Americans, many of those resolutions are about improving your health. Whether you’re trying to make changes in your professional life, socialize more, eat better, exercise regularly, or imbibe less, at the core, you’re really talking about emotional, physical, or mental health.

Not only are these goals achievable in the new year, but you can take big steps in the right direction to accomplish all of them just by focusing on one thing – drinking more water.

You wouldn’t be the only one with that goal, either. In an Aquasana survey we conducted of 2,000 respondents earlier this month, we found that more than one-third (36%) said “drink more water” has been or will be one of their New Year’s resolutions.

Everyone knows that hydration is essential to being healthy, but it’s hard to comprehend the extent to which water benefits your body. Worry not becoming the “new you” for next year is closer than you think.


There are a few reasons that drinking water is good for your physical health, but let’s start with the basics. alexander-redl-d3bYmnZ0ank-unsplash

The human body is 60 percent water and it uses this water to power several bodily functions including digestion, absorption of nutrients, circulation, and moderation of body temperature. The brain works with the posterior pituitary gland (a small gland at the base of the skull that senses the body’s needs) to tell the kidneys how much water to reserve for bodily functions and what amount can be let go as urine. Even mild dehydration can lead to several impaired functions, so staying hydrated will help your body function efficiently. But there’s more to it than that.

Drinking water aids weight loss. A study published in Obesity found that middle-aged adults who drank 500 mL (approximately 2 cups) of water before eating reduced-calorie meals lost more weight than adults who only ate a reduced-calorie diet. Findings suggest that drinking water before eating a meal resulted in smaller food portions throughout the day. While eating a reduced-calorie diet is one way to lose weight, you may follow different dietary guidelines. Fortunately, that won’t affect the results. Drinking water regularly will lead to a reduction in weight, regardless of diet (low-carb, low-fat, whole-food, etc.), sociodemographic variables, baseline weight, or physical activity.

Now you’re losing weight just by supplementing your diet with water, but perhaps you’d also like to be fit. Maybe your goals for the New Year include running a 5K or building strength with some weights. Before you reach for the Gatorade, keep in mind that although sports drinks are marketed as the key to optimizing your workout, that’s only true sometimes. Recent findings suggest that unless your workout is longer than an hour or you’re losing a significant amount of sweat, it makes more sense to just drink water. If someone exercises for less than an hour or the exercise isn’t particularly strenuous, drinking a sports drink may be counterproductive and has been linked to weight gain and even obesity. On the flip side, drinking water during exercise can maintain peak performance, reduce your target heart rate, and lessen the likelihood of developing heat exhaustion.

Finally, there are quite a few positive side effects of water that you may benefit from in the long run, including headache prevention, reduced risk of heart disease, and regularity in bowel movements.


Maybe your goal isn’t to improve physical fitness, but mental fitness – study for a new certification, change jobs, get a promotion, or finish the NYT crossword by yourself. Drinking a healthy amount of water will help you reach these goals as well.

Even moderate dehydration, measured as 2 percent of your body weight, will lead to impaired concentration and memory skills. If your body is 60 percent water, it follows that your brain is also made up of a significant amount of water (75 percent to be exact). When the brain is fully hydrated, it works optimally. A hydrated brain helps you think faster, focus for longer periods of time, avoid “brain fog”, and experience increased creativity. With adequate preparation, water will help you rock your next interview, be a more active participant in your work meeting, or retain the information you need to complete that crossword puzzle.


Sometimes, all you want for the New Year is to experience happiness, contentment, and emotional wellbeing. This is easier said than done. But especially amidst the hustle and bustle of day-to-day stress, hydration can be one less thing to worry about. Studies have found that mild dehydration can cause tangible differences in mood. Or rather, staying hydrated can take you from a “meh” day to a-ok! Further, when people are mildly dehydrated, they perceive a problem as more difficult, which means you’ll use the same mental capacity to solve the problem, but it will feel harder when you’re mildly dehydrated.

There you have it. If you’re still mulling over your resolutions for the year ahead, it’s worth your while to consider adding hydration to your list.
