TIRED AND DEPRESSED?  DRINK MORE WATER

Mild dehydration may modify mood.

The study – published in the British Journal of Nutrition – reports that the mild dehydration, which occurs even before we become thirsty, could be enough to alter mood and energy levels and ability to think clearly, leaving US cranky and tired, say researchers.

 Researchers revealed that the adverse effects from mild dehydration (defined as an approximate 1.5% loss in normal water volume) were the same whether people were sitting at rest or active and exercising.

The results assert the importance of staying properly hydrated at all times, and not just during exercise, extreme heat, or exertion.

 Our thirst sensation doesn’t really appear until we are 1 or 2 percent dehydrated. By then dehydration is already setting in and starting to impact how our mind and body perform.

 Even mild dehydration that can occur during the course of our ordinary daily activities can degrade how we are feeling – especially for women, who appear to be more susceptible to the adverse effects of low levels of dehydration than men.

 Also, the adverse mood changes in both sexes may limit the motivation required to engage in even moderate aerobic exercise.
