Dehydration (in Adults) and How to Prevent It What is dehydration? Dehydration is not having enough water in your body. You need water to breathe, sweat, pass urine and stool and stay healthy. When you do not have enough water, you are at higher risk for problems such as: • kidney stones • low blood pressure • heat exhaustion • urinary tract infections • kidney failure • constipation • salivary gland function problems What causes dehydration? There are many causes for dehydration. Some of these are: • changes from aging such as less desire to drink or having poor taste buds • drinking too much caffeine or alcohol • exercising • being outside in hot weather • fever, infection, vomiting, diarrhea • not being able or allowed to have fluids because of medical problems • taking medications such as water pills and some heart medications • overusing laxatives What are the signs dehydration? There are many signs of dehydration. Some are: • feeling light-headed • headaches • feeling very tired • muscle cramps • dry mouth, lips, nose, sunken eyes • dark urine with a strong smell • reduced urine output • falling • feeling confused Ways to prevent dehydration . • Follow a healthy diet. If you would like some help with your diet or have a medical problem, talk to your doctor or a dietitian. • Drink 6 to 8 glasses of water a day to maintain your fluid balance. If you have heart or kidney disease, talk to your doctor or a dietitian to see how much you can drink. • Check the colour of your urine. When your urine is dark or strong smelling you may need more fluids. • If you have diarrhea, vomiting or a fever, drink more fluids. • Avoid excess alcohol and drinks with caffeine such as coffee, tea, chocolate milk and some soft drinks. These cause you to lose more fluid. • Drink before, during and after exercise or increased activity. • Avoid salty foods after exercise. • Find a cool place when the weather is hot. When you are outside in the heat . • Drink water before you leave home and bring water with you. • Wear cool clothing and a hat. • Avoid being in direct sun. • Avoid exercising too much when it is hot. • Take breaks and drink often. • Take a cool shower when you return home and drink more water. Remember . If you have heart or kidney disease, talk to your doctor or a dietitian about how much you can drink. PD 4646 (Rev 04-2010) File: peyles .

It is indicated in the treatment of resistant oedema where this is associated with secondary hyperaldosteronism; conditions include chronic congestive cardiac failure and hepatic cirrhosis. Treatment with Lasilactone® should be reserved for cases refractory to a diuretic alone at conventional doses. This fixed ratio combination should only be used if titration with the component drugs separately indicates that this product is appropriate. The use of Lasilactone® in the management of essential hypertension should be restricted to patients with demonstrated hyperaldosteronism. It is recommended that in these patients also, this combination should only be used if titration with the component drugs separately indicates that this product is appropriate. POSOLOGY AND METHOD OF ADMINISTRATION For oral administration. The dose must be the lowest that is sufficient to achieve the desired effect. Adults: 1-4 tablets daily. Children: The product is not suitable for use in children. Elderly: Frusemide and Spironolactone may both be excreted more slowly in the elderly. Tablets are best taken at breakfast and/or lunch with a generous amount of liquid (approx. 1 glass). An evening dose is not recommended, especially during initial treatment, because of the increased nocturnal output of urine to be expected in such cases.

Preventing Dehydration
State of New Jersey Department of Human Services Division of Developmental Disabilities DDDDDD PREVENTIONPREVENTION BULLETINBULLETIN Dehydration Dehydration is a loss of too much fluid from the body. The body needs water in order to maintain normal functioning. If your body loses too much fluid - more than you are getting from your food and liquids - your body loses electrolytes. Electrolytes include important nutrients like sodium and potassium which your body needs to work normally. A person can be at risk for dehydration in any season, not just the summer months. It is also important to know that elderly individuals are at heightened risk for dehydration because their bodies have a lower water content than younger people.

The Effect of Dehydration, Hyperthermia, and Fatigue on Landing Error Scoring System Scores
ABSTRACT THE EFFECT OF DEHYDRATION, HYPERTHERMIA, AND FATIGUE ON LANDING ERROR SCORING SYSTEM SCORES Purpose: To examine the effects of exercise-induced dehydration, hyperthermia, and fatigue on Landing Error Scoring System (LESS) scores during a jump-landing task, and the effectiveness of a personalized hydration plan. Methods: Five recreationally active heat-acclimatized males 25.4 y (SD=5.7) completed two trials: with fluid replacement, (EXP) and without fluid (CON), in a counterbalanced, randomized, cross-over fashion. Exercise was terminated when gastrointestinal temperature (Tgi) = 39.5°C and fatigue ≥ 7/10, or 90 min of exercise. Percent dehydration was determined by body mass change from pre- exercise (PRE) and post-exercise (POST). Tgi, heart rate (HR), and perceived fatigue were measured PRE, during exercise, and POST. Three jump-landing tasks were filmed in the frontal and sagittal planes. An experienced grader evaluated jump-landing tasks using the LESS. Statistical Analysis: Repeated measures ANOVA assessed primary dependent and independent variables while a priori dependent t-tests evaluated pairwise comparisons. Results: No interaction, group, or time main effects were observed for LESS scores (p=0.437). POST dehydration (%) was greater in CON (M=2.59, SD=0.52) vs. EXP (M=0.92, SD=0.41; p<0.001), whereas hyperthermia (°C) (CON, M=39.29, SD=0.31, EXP, M=39.03, SD=0.61; p=0.425), and fatigue (CON, M=9, SD=1, EXP, M=9, SD=2; p=0.424) were similar. Conclusion: LESS scores were not affected by exercise-induced dehydration, hyperthermia, and fatigue, nor by a personal hydration plan.

Water Requirements, Impinging Factors, and Recommended Intakes
Rolling Revision of the WHO Guidelines for Drinking-Water Quality Draft for review and comments (Not for citation) Water Requirements, Impinging Factors, and Recommended Intakes By A. Grandjean World Health Organization August 2004 2 Introduction Water is an essential nutrient for all known forms of life and the mechanisms by which fluid and electrolyte homeostasis is maintained in humans are well understood. Until recently, our exploration of water requirements has been guided by the need to avoid adverse events such as dehydration. Our increasing appreciation for the impinging factors that must be considered when attempting to establish recommendations of water intake presents us with new and challenging questions. This paper, for the most part, will concentrate on water requirements, adverse consequences of inadequate intakes, and factors that affect fluid requirements. Other pertinent issues will also be mentioned. For example, what are the common sources of dietary water and how do they vary by culture, geography, personal preference, and availability, and is there an optimal fluid intake beyond that needed for water balance? Adverse consequences of inadequate water intake, requirements for water, and factors that affect requirements Adverse Consequences Dehydration is the adverse consequence of inadequate water intake. The symptoms of acute dehydration vary with the degree of water deficit (1). For example, fluid loss at 1% of body weight impairs thermoregulation and, thirst occurs at this level of dehydration. Thirst increases at 2%, with dry mouth appearing at approximately 3%. Vague discomfort and loss of appetite appear at 2%. The threshold for impaired exercise thermoregulation is 1% dehydration, and at 4% decrements of 20-30% is seen in work capacity.

Toolbox Talks
TOOLBOX TALKS Hangovers and dehydration The purpose of this toolbox talk is to provide some basic information about “hangovers” and how they are a potential job safety issue. This will primarily address “the morning after” effect. The hangover is caused in part by dehydration, and drinking alcohol can lead to dehydration. Alcohol has a diuretic effect. Alcohol increases the body’s production of urine, leading to a loss of fluids and electrolytes that are needed for normal body functioning. Excessive drinking can cause vomiting, leading to further loss of fluids and electrolytes. Although dehydration is not the only cause of a hangover, it contributes to commonly known hangover symptoms, such as increased thirst, fatigue, headache and dizziness. Here are three tips on how to avoid and address a hangover: 1. When drinking alcohol, alternate between a glass of water and a drink. Though this won’t necessarily prevent dehydration, it can help moderate alcohol intake. 2. Increasing your water intake in general may help reduce some symptoms of hangovers, and even prevent them altogether. 3. If you have a hangover, stay hydrated with water or electrolyte-rich drinks, such as sport drinks. Be careful with sport drinks: they usually also contain a lot of sugar. Being dehydrated because of a hangover, like any other sickness, can impact your ability to focus on the job. Even if your blood alcohol level is low enough and you can legally work, you should still consider your physical state as impaired and potentially dangerous. Here are four questions to ask yourself before going to work if you are hungover: 1.
