One thing I’m guilty of at work is not drinking enough water. I’m pretty good at catching up once I start feeling parched, but it’s better to be proactive and drink as soon as you feel thirsty. I’ve found that being dehydrated affects my energy levels more than anything. Even if I’ve eaten a big breakfast and slept well, I find that my concentration levels are decreased. Besides the physical discomfort and annoyance of being thirsty, low fluid intake can affect daily functioning, mood and productivity. In some extreme cases, you may even find yourself fatigued or dizzy. In these cases, many people reach for a snack when they are actually thirsty.
