Drinking too little water may amplify stress response

People who drank less than 1.5 liters of fluid per day had a cortisol response to stress over 50% higher, according to a new study.

Why it matters

  • Drinking too little water can increase stress hormone levels.
  • Poor hydration is linked to higher risks of heart disease, diabetes, and depression.

By the numbers

  • Cortisol response was over 50% higher in those drinking less than 1.5 liters per day.
  • Recommended daily fluid intake: 2 liters for women, 2.5 liters for men.

The big picture

  • Hydration plays a crucial role in managing stress and overall health.
  • Simple habits like carrying a water bottle can have long-term health benefits.

What they're saying

  • Some commenters question if diet drinks count as fluids.
  • Observations about hydration habits in older generations.
  • The study was funded by Danone R&I, which may have a vested interest.

Caveats

  • Study funded by Danone R&I.
  • Results based on healthy young adults; may not apply to all populations.
  • More long-term studies needed.

What’s next

  • Further research to confirm and expand findings.
  • Practical hydration tips, like monitoring urine color.
