Rumors that prolonged use of diet pills, combined with her hectic schedule, had led to Brandy's illness prompted the young singer-actress to categorically deny allegations of addiction to diet medications. Walls believes that many performers are legitimately at greater risk for dehydration than the average person because the extremely busy lifestyles stars lead often do not allow for proper fluid replacement and diet. Celebrities often push themselves to the limit, leaving insufficient time to eat, drink and sleep regularly. Performing, especially under hot lights, and even airline travel can dehydrate a person. Walls also points out that caffeine and alcohol use can also contribute to dehydration.
Caffeine is a diuretic.
It stimulates water loss. Increase fluid intake when exercising and in hot weather. When dehydrated, electrolyte-balanced drinks, like many sports drinks, are better than plain water. If symptoms worsen, go to a doctor or hospital immediately. Luckily for Carey, she received prompt medical attention long before her dehydration became life-threatening.
