How Hydration Affects Cognition and Memory

https://spencerinstitute.com/certific.... Your brain needs proper hydration for optimal function. This is just one thing you'll learn in detail in he Spencer Institute Brain Fitness Coach Certification. The brains of dehydrated adults show signs of increased neuronal activation when performing cognitively engaging tasks, indicating that their brains are working harder than normal to complete the task. In healthy young adults, this additional effort typically manifests as fatigue and changes in mood, but in populations with less cognitive reserve, such as the elderly, this can lead to a decline in cognitive performance. Although it has been suggested that decrements in cognitive performance are present in the range of a 2 to 3% reduction in body weight, several dose-response studies indicate dehydration levels of 1% may adversely affect cognitive performance. When a 2% or more reduction in body weight is induced by heat and exercise exposure, decrements in visual-motor tracking, short-term memory and attention are reported, but not all studies find behavioral effects in this range.
