Maintaining daily hydration is crucial to everyday health and wellbeing to ensure that bodies perform at their optimum. Around 60% of body weight is water, increasing to 73% of the brain, so it makes sense that even mild dehydration can have an impact on physical and mental performance. Everyday activities such as breathing and sweating cause water loss, add to this an air conditioned or heated office and it’s really easy for employees to become dehydrated, which can start to have detrimental impacts on workplace performance. Studies have found that hydration levels can have an effect on cognitive (brain) function and more severe dehydration can also reduce short-term memory and the ability to process and interpret visual information. In a working environment, this could lead to poor concentration and mistakes being made.
