Question

I recently read where getting even mildly dehydrated can affect your mood, not just your physical health. Is that true?

Answer

Absolutely. And in the start of winter, it’s a good time to remember that staying properly hydrated is vital for the health of your mind and body. Every system in your body relies on adequate fluid levels to operate safely and effectively. That means, even in the cold weather, you have to keep up with your intake of water and other fluids (not including alcohol and soda, which act as diuretics, reducing fluid levels in the body). Even the earliest stages of dehydration—before you feel thirsty—can affect your ability to concentrate and make decisions. You can become irritable and sluggish. Try to drink six to eight glasses of water throughout the day, and more if you are especially active. If you are frail, or have a condition such as heart failure that requires limited fluid intake, talk with your doctor about ways to hydrate safely.
