@med_pulse: 💧 Less than 1.5 L water a day raises stress A British study finds that adults drinking under 1.5 litres daily release higher cortisol - the body’s main stress hormone - when under pressure. Hydration was tracked for a week before participants faced interviews and arithmetic tests. Those with lower fluid intake showed sharper cortisol spikes, despite reporting similar anxiety. Chronic cortisol elevation is linked to heart disease, diabetes and depression. Regular fluid intake, though simple, appears to blunt the body’s stress response. 🔗 Read the study: https://www.ljmu.ac.uk/about-us/news/articles/2025/8/22/dehydration-and-stress-study #Hydration #Stress #HealthNews #Wellbeing #Science
