Is water good for our brains?

• Water and Brain Health: Key Clinical Takeaways
• Adequate hydration is essential for optimal brain function; dehydration impairs cognitive performance, concentration, and memory, making fluid intake a modifiable factor in mental performance
• Individual water requirements vary based on age, activity level, climate, and health status; there is no universal "one-size-fits-all" recommendation, requiring personalised assessment
• GPs should counsel patients on recognising hydration status through urine colour and symptom awareness, particularly in vulnerable groups (older adults, children, those with chronic conditions) at higher risk of dehydration-related cognitive decline

We all know water is good for us - but how much do we really need to drink? And is it good for our brains too?
