PART I OF II
DRINK MORE WATER EACH DAY TO
Optimize Mood & Mental Tasks By Lawrence E. Armstrong, PhD
This article represents Part I of a two-part series. It explores the scientific studies that demonstrate the value of drinking water to optimize mood and cognitive processes. Part II, which will be published in the March/April 2017 issue of Bottled Water Reporter, will explore recent studies that link low daily water intake to a number of chronic diseases and will provide simple recommendations to help you maintain an optimal level of hydration. Most adults recognize that water is essential to health because it supports numerous physiological functions, including vision, circulation, metabolism, excretion of waste products, and regulation of body temperature. However, few people are aware of recent research that has discovered interesting and valuable cognitive benefits of consuming water each day.
water loss in these studies is approximately 1.0-1.5 percent of body weight, which is considered a mild level of dehydration. Studies comparing these dehydrated participants to a group of control subjects (who consumed as much water as they desired, and whenever they desired it, ad libitum) have revealed several interesting effects.
Scientists who study the effects of daily water intake on the human body asked test participants to stop drinking for half a day or longer, then observed the detrimental effects of the resulting dehydration. The amount of
