Myths about healthy drinking may be putting older people’s health at risk by discouraging them from drinking enough fluid to stay healthy, according to a new UCL-led study. Dehydration is thought to affect between a third to nearly half of frail older people and is associated with a higher risk of adverse health outcomes, from having a stroke or a fall to being admitted to hospital.
For example, it is known that people who are admitted to hospital after a stroke are more than twice as likely to suffer significant impairment if they are dehydrated when they are admitted*.
