Hydrate!
That “eight glasses of water a day” may or may not be something you subscribe to, but what you definitely should not allow to happen is dehydration. It’s such a horrible and unnecessary thing to do to yourself and really, why would you deprive your body of something that has about a million of benefits? Ensure you hit the water cooler every few hours. Added bonus? Who knows who you might run into while there?! Talk about an energy boost!
