disclaimer the camelbak hydration calculator was built in cooperation with the university of connecticut s korey stringer institute ksi . the calculator is designed to educate you about the different factors that influence dehydration requirements during activity . it is meant to give you a general indication of your sweat losses during activity and should not take the place of specific individual needs medical advice or common sense . if the conditions of your activity change you should reassess your hydration strategy accordingly . for a more precise understanding of your hydration requirements during physical activity follow the steps outlined in ksi s sweat rate calculation worksheet . consult your doctor before starting a new diet or exercise routine . tell us about yourself gender though we don t account for it in this calculation pregnant or breastfeeding women tend to require slightly more water intake than usual . if you are pregnant or breastfeeding please consult your doctor before embarking on a rigorous exercise routine . a fit male will sweat more than a fit female during intense exercise due to higher producing sweat glands . height height combined with weight provides us with your body mass index or bmi . bmi is used in our calculation to factor in the surface area of your skin . the more surface area you have the greater amount of sweat you produce . formula weight height 2 weight weight combined with height provides us with your body mass index or bmi . bmi is used in our calculation to factor in the surface area of your skin . the more surface area you have the greater amount of sweat you produce . formula weight height 2 age interestingly age does affect how the human body uses water . for example as people age their kidney is not able to conserve water as well . also their thirst sensation tends to lessen making them more susceptible to dehydration . gender height height feetinches up down weight weight lbs age age yrs what s your current hydration level what color is your urine the best way to assess your current hydration level is urine color . your selection here tells us whether or not you are beginning your activity with a water deficit . to maintain healthy hydration levels throughout the day regulate water intake so that you excrete urine that is the color of lemonade not apple juice . hydrated video easy tips for

your urine 1 2 3 4 5 6 7 how much do you typically sweat light moderate heavy describe your activity activity each activity exerts different demands on the body and can affect sweat levels . we have included a basic selection of sports that encompass high aerobic to anaerobic activities . if your chosen sport or exercise is not listed here simply choose the activity that most closely mirrors yours as far as physical demand . activities can dictate the type of apparel you wear and the type of gear you may be carrying . typically clothing adds insulation and increases your sweat rate . the addition of backpacks to hikers increases the energy costs of locomotion and reduces the surface area available for heat transfer thereby further increasing dependence on sweating to cool the body . sports in which protective equipment is worn eg football should ensure that frequent hydration breaks are implemented into a practice session since this type of equipment has also been shown to affect heat dissipation from the body during exercise . read more at hydrated . time time and intensity are two of the largest factors in determining how much water you should drink during your exercise or race . obviously the longer you are out there the greater your total water requirement . intensity more than any other factor intensity will significantly influence your hydration requirements . are you running close to top speed flat out for 30 minutes or are you running closer to a jogger s pace for 30 minutes the difference in sweat rate and therefore hydration demands could be significant . it s important to honestly assess your intensity as this is a critical factor in your overall hydration needs . as your intensity increases you sweat more and therefore dehydrate at a faster rate . to sustain a high intense workout for a longer period of time it s important to understand your target water consumption and drink consistently throughout the session to keep your body s hydration level in balance . this will keep your muscles functioning properly to reach optimal endurance levels . learn more about how your body uses water . activity activity activity.index up down time time

humidity conditions in hot tropical environments can increase water requirements as much as 2 fold . temperature intense workouts in heat have a role in both dehydration rates and cognitive function such as hand eye coordination and concentration . dehydration rates in the heat have a smaller safety net than an activity performed in 40 degree weather . dehydration increases exercising core body temperature and when exercising in the heat dehydration will lead to a greater core body temperature than when hydrated . exercise in the heat has the potential to limit exercise performance due to the cardiovascular thermoregulatory metabolic and neuromuscular changes that occur in the body . what are the weather conditions choose weather weather weather.index up down temperature f c your
