Drinking just one more glass of water can help you feel better, have more energy and be healthier, Michelle Obama said during a speech at Watertown High School.

The First Lady asked people to “Drink Up” as part of a new initiative promoting the benefits of drinking water.

“We are what we drink and when we drink water, we certainly ‘drink up,’” Obama said.

She said with the new campaign, the organizations and community and nationwide leaders involved hope to make a huge impact on people’s lives.

Obama says the PSAs, posters and promotional material will be seen a billion times.

“The Drink Up logo will go on a half billion water bottles,” the First Lady said. The organization will be reaching out to social media network of nearly 140 million followers and fans.

“This isn’t just a drop in the bucket. We’re hoping to make a huge splash,” Obama said, acknowledging her puns with a laugh.

The First Lady wants people across the nation to spread the word about the campaign; visit www.youarewhatyoudrink.org and use the hashtag #DrinkH20 on Instagram, Twitter and Facebook.

"Just drink one more glass of water a day. If we all ‘drink up,’ we’ll all feel better, we’ll have a more energy; we’ll have more productive students…and a healthier country."
