Expatriate health insurance policyholders will need to ensure they take on plenty of fluids over the summer months and one expert has noted there are alternatives to water for those who want to vary how they stay hydrated.
Food psychologist Dr Christy Fergusson explained drinks such as juices, smoothies and herbal teas can also help keep the body well-stocked with fluids, while the liquid content of fruit and vegetables contributes to a daily intake.
Glasgow GP Margaret McCartney recently argued in an article for the British Medical Journal that there is no scientific evidence to back up the government's suggestion that people should drink six to eight glasses a day and Ms Fergusson noted that this is merely "a guideline".
"People eating junk food or lots of processed foods are not going to get as much hydration, so they would probably need to have more water," she said, adding it is also important to take on more fluids during exercise.
