Hydration needs can change depending on physical activity, temperature, humidity, illness, altitude, and other environmental conditions. When people exercise or spend time in hot weather, they can lose more fluid through sweating and may need to pay greater attention to replacing those losses. The Centers for Disease Control and Prevention notes that water helps the body maintain normal temperature and that people generally need more water when they are in hot climates or are more physically active.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding changing hydration needs is especially important for people who exercise, work outdoors, participate in sports, travel to different climates, or spend long periods in warm environments. However, hydration is not simply about drinking as much water as possible. Both inadequate fluid intake and excessive fluid intake can create problems. Research on physically active individuals recommends individualized hydration strategies that consider factors such as sweat rate, environment, body size, exercise duration, intensity, and heat acclimatization.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Hydration?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hydration refers to maintaining an appropriate amount of water and other fluids in the body.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Water plays several important roles, including helping the body:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Maintain normal temperature<\/li>\n\n\n\n<li>Lubricate and cushion joints<\/li>\n\n\n\n<li>Support normal physical function<\/li>\n\n\n\n<li>Transport nutrients<\/li>\n\n\n\n<li>Remove waste<\/li>\n\n\n\n<li>Replace fluid lost through sweating<\/li>\n\n\n\n<li>Support normal circulation<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The CDC explains that adequate water intake helps prevent dehydration and supports normal body function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because the body continually loses water through processes such as sweating, urination, breathing, and other normal functions, fluids need to be replaced regularly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Hydration Needs Are Different for Everyone<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is no single amount of water that is appropriate for every person in every situation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hydration needs can vary according to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Age<\/li>\n\n\n\n<li>Body size<\/li>\n\n\n\n<li>Physical activity<\/li>\n\n\n\n<li>Exercise intensity<\/li>\n\n\n\n<li>Exercise duration<\/li>\n\n\n\n<li>Temperature<\/li>\n\n\n\n<li>Humidity<\/li>\n\n\n\n<li>Sweat rate<\/li>\n\n\n\n<li>Clothing<\/li>\n\n\n\n<li>Altitude<\/li>\n\n\n\n<li>Health conditions<\/li>\n\n\n\n<li>Diet<\/li>\n\n\n\n<li>Illness<\/li>\n\n\n\n<li>Individual tolerance<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association recommends individualized hydration strategies for physically active people because fluid needs can differ substantially between individuals and environments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This means that hydration recommendations should be considered in context rather than treated as a fixed daily number.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Physical Activity Changes Hydration Needs<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Physical activity increases the body&#8217;s demand for fluid because exercise can increase sweating and heat production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During exercise, the body uses sweating as an important mechanism for releasing heat. If fluid loss through sweating becomes greater than fluid replacement, dehydration can develop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The amount of fluid lost during exercise varies widely. A person exercising lightly in a cool environment may lose much less fluid than someone performing intense exercise outdoors in hot and humid conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association recommends considering individual sweat rate and the environment when developing hydration strategies for physically active people.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Exercise Intensity Matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not all physical activity produces the same amount of fluid loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Higher-intensity exercise generally creates greater heat production and may increase sweating. Activities involving running, cycling, competitive sports, outdoor workouts, or prolonged physical effort can therefore create greater fluid replacement needs than low-intensity activities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, individual responses differ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two people performing the same workout may have different sweat rates. This is one reason individualized hydration strategies can be more useful than assuming everyone should drink exactly the same amount.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Exercise Duration Also Matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The longer a person exercises, the more opportunity there is for fluid loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A short workout may require a different approach from prolonged exercise lasting an hour or more, particularly in hot environments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During longer activities, hydration planning becomes more important because fluid losses can accumulate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association recommends developing fluid replacement practices that consider exercise duration, intensity, environmental conditions, and individual sweat rate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hot Weather Can Increase Fluid Needs<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hot weather can significantly change hydration requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When environmental temperatures rise, the body relies heavily on sweating and evaporation to remove heat. More sweating means greater fluid loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The CDC states that people who exercise on hot days are more likely to become dehydrated and experience heat-related illness. It recommends drinking more water than usual during hot conditions and taking steps such as scheduling exercise during cooler parts of the day and pacing activity appropriately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People exercising outdoors in hot weather should therefore pay closer attention to hydration, rest, and environmental conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Humidity Also Matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Temperature is not the only environmental factor that affects hydration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Humidity can influence how effectively sweat evaporates from the skin. In very humid conditions, sweat may evaporate less efficiently, making it harder for the body to release heat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This can increase thermal stress during physical activity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association notes that environmental heat stress depends on factors including temperature, relative humidity, wind speed, and radiant energy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, a moderately hot day with high humidity may create more challenging exercise conditions than temperature alone suggests.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Sweating Changes Fluid Requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Sweating is one of the body&#8217;s primary methods of cooling during exercise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As sweat evaporates from the skin, heat is removed from the body. But sweating also results in fluid loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If sweating continues for a long period without adequate replacement, body water can decline.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The amount of sweat produced can vary depending on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Exercise intensity<\/li>\n\n\n\n<li>Temperature<\/li>\n\n\n\n<li>Humidity<\/li>\n\n\n\n<li>Clothing<\/li>\n\n\n\n<li>Fitness level<\/li>\n\n\n\n<li>Heat acclimatization<\/li>\n\n\n\n<li>Individual physiology<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Because sweat rates differ, there is no universal fluid replacement amount that applies to every active person.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hydration During Cold Weather<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hydration is not only a concern during hot weather.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cold environments can also influence hydration behavior. The National Athletic Trainers&#8217; Association notes that thirst can be reduced during cold-weather activity, which may decrease voluntary fluid intake. Cold exposure can also produce physiological changes that influence fluid balance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because people may feel less thirsty in cold conditions, they should not assume that cold weather completely eliminates the need to drink fluids.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This can be especially relevant during prolonged outdoor activities such as hiking, skiing, trekking, or winter sports.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hydration at Higher Altitudes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Altitude can also affect fluid balance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People traveling to high-altitude environments may experience changes in breathing, temperature, activity levels, and fluid loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association identifies altitude as one of the environmental factors that can influence hydration considerations for physically active individuals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People who exercise or travel at altitude should therefore consider the environmental conditions rather than relying entirely on their usual hydration routine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hydration During Humid and Tropical Weather<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">People living in or traveling to tropical climates may experience higher temperatures and humidity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When physical activity is performed in these environments, sweating may increase while evaporation becomes less efficient.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This combination can make exercise feel more difficult and increase thermal stress.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adjusting activity timing, taking appropriate rest breaks, wearing suitable clothing, and maintaining access to fluids can all be useful strategies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Signs That You May Need More Fluids<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dehydration can affect physical and mental well-being.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Possible signs of dehydration may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Increased thirst<\/li>\n\n\n\n<li>Dry mouth<\/li>\n\n\n\n<li>Fatigue<\/li>\n\n\n\n<li>Headache<\/li>\n\n\n\n<li>Dizziness<\/li>\n\n\n\n<li>Reduced physical performance<\/li>\n\n\n\n<li>Darker urine<\/li>\n\n\n\n<li>Feeling unusually weak<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The CDC notes that dehydration can contribute to effects such as unclear thinking, mood changes, overheating, constipation, and kidney stones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More severe symptoms, especially during exercise or hot weather, require immediate attention.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If someone feels faint or weak while exercising in the heat, the CDC recommends stopping activity and moving to a cool place.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Drinking Too Much Water Can Also Be a Problem<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hydration does not mean drinking unlimited amounts of water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Excessive fluid intake during prolonged physical activity can contribute to a condition called exercise-associated hyponatremia, in which blood sodium concentration becomes dangerously low.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association warns that both inadequate hydration and excessive fluid intake can create health risks. It recommends avoiding fluid consumption that exceeds exercise-related losses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the goal is appropriate hydration rather than maximum hydration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Water or Electrolyte Drinks?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For many everyday activities, water can be an appropriate source of hydration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, during prolonged or intense exercise, especially in hot conditions, electrolytes may also become relevant because sweat contains sodium and other substances.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The need for an electrolyte-containing drink depends on factors such as exercise duration, intensity, sweat losses, diet, and environmental conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association notes that carbohydrates and electrolytes may be useful during intense or long-duration activities and that hydration strategies should be individualized.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sports drinks are not automatically necessary for every workout.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hydration Before Exercise<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Starting physical activity adequately hydrated can support normal thermoregulation and physical performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For most recreational activities, maintaining normal hydration throughout the day is generally more useful than consuming very large amounts of fluid immediately before exercise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People preparing for prolonged exercise should consider their usual fluid intake, expected environmental conditions, activity duration, and personal sweat losses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association recommends beginning exercise adequately hydrated and developing individualized plans when greater fluid losses are expected.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hydration During Exercise<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">During exercise, fluid needs depend on how much water is being lost.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People exercising in hot weather may need more frequent access to fluids than those exercising in cooler conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The CDC recommends drinking more water than usual when exercising on hot days and taking precautions such as reducing exposure during the hottest part of the day.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For prolonged activities, individualized hydration planning can be particularly useful.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hydration After Exercise<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hydration continues to matter after exercise because the body may still need to replace fluid lost through sweating.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Post-exercise hydration is especially important when a person has another training session or physically demanding activity later in the day.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The National Athletic Trainers&#8217; Association recommends rehydration after physical activity and considering fluid and electrolyte replacement according to individual needs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Adapt Hydration to the Weather<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A simple way to think about changing hydration needs is to consider the environment before beginning physical activity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cool Weather<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In cooler conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Maintain normal fluid intake.<\/li>\n\n\n\n<li>Do not ignore thirst simply because you are not sweating heavily.<\/li>\n\n\n\n<li>Take fluids during prolonged activity.<\/li>\n\n\n\n<li>Remember that thirst can be less noticeable in cold environments.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Warm Weather<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In warmer conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Increase attention to fluid intake.<\/li>\n\n\n\n<li>Avoid exercising during the hottest part of the day when possible.<\/li>\n\n\n\n<li>Take appropriate breaks.<\/li>\n\n\n\n<li>Wear suitable clothing.<\/li>\n\n\n\n<li>Monitor how you feel during activity.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Hot and Humid Weather<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In hot and humid conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduce exercise intensity when appropriate.<\/li>\n\n\n\n<li>Take more frequent rest breaks.<\/li>\n\n\n\n<li>Ensure fluids are easily accessible.<\/li>\n\n\n\n<li>Watch for symptoms of heat-related illness.<\/li>\n\n\n\n<li>Avoid pushing through dizziness or weakness.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The CDC recommends pacing activity, exercising during cooler times when possible, and drinking more water than usual in hot conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hydration and Physical Recovery<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hydration can also be relevant during physical rehabilitation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People recovering from illness, injury, or surgery may have different activity levels and fluid requirements. Rehabilitation exercises can increase physical activity compared with periods of complete rest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, hydration recommendations may need to be adapted for people with certain medical conditions or fluid restrictions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Individuals with heart, kidney, or other conditions that affect fluid balance should follow the advice of their healthcare professional rather than increasing fluid intake independently.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hydration During Travel<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Travel can change hydration habits because of long journeys, changes in temperature, altered routines, and increased physical activity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People traveling to hot destinations may need to adjust their fluid intake as their body becomes exposed to a warmer environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Travelers who exercise outdoors should consider local temperature and humidity rather than following the same hydration routine they use at home.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Practical Ways to Stay Hydrated<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Simple habits can make hydration easier.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Carry Water<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Keeping water accessible can make it easier to drink regularly throughout the day.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Drink With Meals<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Drinking fluids with meals can contribute to daily fluid intake.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Monitor Activity<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Consider how long and how intensely you are exercising.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Consider the Weather<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hot, humid, or unusually cold conditions may change your fluid needs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Pay Attention to Symptoms<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Unusual weakness, dizziness, or feeling faint during exercise should not be ignored.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Avoid Overdrinking<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">More water is not always better.

While regular water intake is important for everyone, people who exercise or spend time in challenging environmental conditions may need to pay additional attention to fluid replacement. Hot weather can increase sweating and dehydration risk, while cold environments may reduce thirst and make people less aware of their fluid needs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most effective approach is not to drink as much as possible, but to maintain an appropriate balance. Paying attention to activity level, environmental conditions, personal hydration cues, and individual fluid losses can help create a more suitable hydration routine. For prolonged or intense physical activity, particularly in heat, individualized guidance from a qualified healthcare or sports professional may be useful.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Do hydration needs increase during exercise?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Physical activity can increase sweating and fluid loss, so hydration needs may increase depending on exercise intensity, duration, environment, and individual sweat rate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Do you need more water in hot weather?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">People may need more water in hot weather, particularly when they are physically active. The CDC recommends drinking more water than usual when exercising on hot days.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Does humidity affect hydration?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. High humidity can reduce the effectiveness of sweat evaporation, increasing heat stress during physical activity. Environmental humidity is therefore an important factor when considering hydration and exercise conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Do you need to drink more water in winter?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not necessarily more than in hot weather, but cold weather does not eliminate the need for hydration. Thirst can be reduced during cold-weather activity, so people may need to consciously maintain normal fluid intake.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Can drinking too much water be harmful?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Excessive fluid consumption during prolonged exercise can contribute to exercise-associated hyponatremia, a potentially serious condition involving low blood sodium.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Is water enough for exercise?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For many everyday activities and shorter workouts, water may be sufficient. During prolonged or intense exercise, especially in hot conditions, electrolytes and carbohydrates may sometimes be useful depending on individual needs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. What are common signs of dehydration?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Possible signs include thirst, dry mouth, fatigue, headache, dizziness, weakness, darker urine, and reduced physical performance. More serious symptoms during exercise or heat exposure require prompt attention.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Should I drink water even when I am not thirsty?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hydration strategies can vary. For prolonged or intense physical activity, individual sweat rate, environmental conditions, and access to fluids should be considered. The safest strategy is to avoid both significant dehydration and excessive fluid intake.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">9. Does physical activity increase water requirements?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Increased physical activity can increase fluid losses through sweating, which may increase hydration needs. The CDC specifically lists increased physical activity as a situation in which people may need more water.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">10. Who should get professional advice about fluid intake?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">People with medical conditions that affect fluid balance, such as certain heart or kidney conditions, should follow individualized advice from their healthcare professional.
