Hydration and mental health: Could your glass of water be a natural antidepressant?

Hydration and mental health: Could your glass of water be a natural antidepressant?

Have you ever felt irritable, drained, or just unable to focus—only to realize you hadn’t had a sip of water all day? In Canada, where life often moves at a hectic pace, this basic need is easy to overlook. But here’s something that might change your routine: hydration has a direct impact on mental well-being. And science backs it up.

A thirsty brain is a struggling brain

The human brain is about 75% water. When the body is even slightly dehydrated, brain function slows down—like a machine running low on fuel.

  • Just a 2% drop in hydration can reduce cognitive performance by 10% (Journal of Nutrition)
  • Dehydration increases cortisol production, the hormone linked to stress (University of Connecticut)
  • Around 85% of Quebecers reportedly don’t drink enough in the winter—ironically, a key season for mood regulation

As Montreal-based neurologist Dr. Sarah Lemieux explains: “Trying to get your brain to function without enough water is like running a coffee machine with no water. It just doesn’t work.”

Three signs your mental health might be dehydrated

  1. The 3 PM slump: that mid-afternoon crash might just be your body’s way of asking for water
  2. Friday night crankiness: a 2018 study linked mild dehydration to a 30% rise in mood swings
  3. Mental fog: trouble making decisions or staying focused? Your brain could be running on empty
