Thirst and hydration status in everyday life.

Water is an essential nutrient for all persons; thus, maintaining a chronic state of optimal hydration is recognized to provide health benefits. Fluid balance is maintained via thirst, a feedback-controlled variable, regulated acutely by central and peripheral mechanisms. However, voluntary drinking is also a behavior influenced by numerous social and psychological cues. Therefore, whether "thirst-guided" [...]

Methods for assessing the effects of dehydration on cognitive function.

Studying the effects of dehydration on cognitive function presents a variety of unique and difficult challenges to investigators. These challenges, which are addressed in this article, can be divided into three general categories: 1) choosing an appropriate method of generating a consistent level of dehydration; 2) determining and effectively employing appropriate and sensitive measures of [...]

Hydration for recreational sport and physical activity.

This review presents recommendations for fluid needs and hydration assessment for recreational activity. Fluid needs are based on sweat losses, dependent on intensity and duration of the activity, and will vary among individuals. Prolonged aerobic activity is adversely influenced by dehydration, and heat exposure will magnify this effect. Fluid needs predicted for running 5-42 km at [...]

Hydration-dehydration, heat, humidity, and “cool, clear, water”.

Personal recollections of dehydration meltdowns during the Kona Ironman Triathlon, reflections on their cause, and the author's experiential recommendations regarding hydration, prevention of dehydration, and "beat the heat and humidity" measures. http://www.ncbi.nlm.nih.gov/pubmed/23147099n

Principles of Exercise Physiology: Responses to Acute Exercise and Long-term Adaptations to Training.

Physical activity and fitness are associated with a lower prevalence of chronic diseases, such as heart disease, cancer, high blood pressure, and diabetes. This review discusses the body's response to an acute bout of exercise and long-term physiological adaptations to exercise training with an emphasis on endurance exercise. An overview is provided of skeletal muscle [...]

Exercise-Associated Hyponatremia and Hydration Status in 161-km Ultramarathoners.

PURPOSE: This work combines and reanalyzes five years of exercise-associated hyponatremia (EAH) research at 161-km ultramarathons in northern California with primary purposes to define the relationship between post-race blood sodium concentration ([Na]) and change in body weight, examine the interactions among EAH incidence, ambient temperature and hydration state, and explore the effect of hydration status [...]

Parenteral Hydration in Patients With Advanced Cancer: A Multicenter, Double-Blind, Placebo-Controlled Randomized Trial.

PURPOSE: The vast majority of patients with cancer at the end of life receive parenteral hydration in hospitals and no hydration in hospice, with limited evidence supporting either practice. In this randomized controlled trial, we determined the effect of hydration on symptoms associated with dehydration, quality of life, and survival in patients with advanced cancer. [...]

Controlling the hydration of the skin though the application of occluding barrier creams.

The skin is a barrier membrane that separates environments with profoundly different water contents. The barrier properties are assured by the outer layer of the skin, the stratum corneum (SC), which controls the transepidermal water loss. The SC acts as a responding membrane, since its hydration and permeability vary with the boundary condition, which is [...]

The effect of acute fluid consumption and hydration status on percent body fat and minimum wrestling weight.

ABSTRACT: The weight certification program for wrestling requires a urine specific gravity (Usg) < 1.020. However, the effect of acute rehydration on percent body fat (%BF) and minimum wrestling weight (MWW) is largely unknown. We examined the effect of acute fluid consumption on %BF and MWW. Twenty-five male subjects (18-22 y) were tested in a [...]
