Chronic low water intake impairs recovery and compromises immunity 🚨

Pay attention to plain water intake!

Chronic low water intake is associated with altered exercise-induced oxidative stress and immune cell responses: a cross-sectional study

Study Details

This new study assessed water intake of 26 participants who were then classified into…

💧 HIGH = 1.22 ± 0.19 L/d

🥵 LOW = 0.41 ± 0.10 L/d

Participants then completed a maximal graded exercise test, with oxidative stress and immunological markers assessed at baseline and post-exercise 🔍

There were also no differences between groups in “other beverage” daily intakes 🥤

Here is what they found ⬇️

Key Findings

At baseline the LOW group showed elevated levels of reactive oxygen metabolites (ROMs)‼️

In the exercise test, both groups showed similar performance outcomes including…

🫀 peak heart rate

🫁 VO2max

⏰ exercise duration

However, biological markers differed drastically ⚠️

🩸 Serum biological antioxidant potential (BAP) significantly increased in the HIGH group only

☠️ The LOW group showed a larger increase in peripheral blood mononuclear cell death (absolute and relative)

Plus further compromised immune responses 🤧

Conclusion

Chronic low water intake impairs both exercise recovery and immune responses 🚨

Total fluid intake is important but there should also be a focus put on total plain water intake for optimal health and recovery ✅
