There are some people who might need added electrolytes, like laborers and construction workers who have dring work outside in the heatsoldiers who are training and exercising all day and high-level athletes, who train several times a day.
However, Casa says there is an important benefit with flavored sports drinks: People love them. Plus, drinks with sodium help your body retain fluids better and also keep you thirsty, so you drink more.
Casa suggests keeping your beverages cold to make them taste better and to help cool down your body. Stavros Kavouras, assistant dean of graduate education and professor of nutrition at Arizona State University who studies hydration and its impact it has on health and performance, says rather than relying on a certain number of glasses of water — like the usual eight glasses a day recommendation you often hear — instead pay attention to two simple biomarkers: how often you urinate and what color it is.
When optimally hydrated, you should be going to the bathroom every two to three hours and your urine should look similarly colored to lemonade. If it looks more like orange juice that's an indication that your body is trying to conserve water and you need to hydrate more.

: Hydration needs during extreme weather conditions| Why hydration still matters in cold climates and how to nail your strategy | Patient Education Dec 2 As temperatures drop it can become harder to keep hydration up. Regardless of the temps outside, staying hydrated is important all year round. Every time you sweat, urinate, or have a bowel movement, water is lost. A lack of water not only results in dehydration but can increase your risk of kidney stones, urinary tract infections, and constipation. Water is necessary for transporting nutrients, removing waste from the body, supporting the immune system, hydrating your tissues and organs, maintaining blood pressure as well as maintaining a proper body temperature. This is important for preventing hypothermia if outdoors in winter. The easiest to monitor is the color of your urine, which should be a pale yellow or clear color. Other signs of dehydration include constipation, dry mouth or chapped lips and skin, headaches, difficulty concentrating, irritability, feeling faint or dizzy and a rapid heart rate. Infants and elderly are at the highest risk for dehydration. The recommended amount of water varies from person to person and depends on factors such as age, sex, activity level, altitude, weather, and overall health. A simple method to determine the minimum ounces of fluid you may need each day is to take your weight in pounds and divide it in half. For example, if you weigh lb, you will require at least 80 fluid ounces per day. This simple tactic can 'trick' your brain into feeling happier, researchers say. Skip Navigation. Related Stories.

The primary system though for cooling off our bodies, especially in hot weather, is evaporative cooling. Evaporative cooling works by the body shunting blood to the surface, and pushing out sweat which comes from blood plasma through the pores in our skin. From there, ideally, the sweat evaporates off our body and cools us down. Instead of switching to a different system, the body will produce more and more sweat, in an attempt to make it work. Oddly enough, the same rapid dehydration occurs in dry, especially cold and dry climates. How is it that in the opposite environment, we have the same problem?

If you often find yourself too cold in the winter, try drinking more water! Symptoms of dehydration include headaches, fatigue, dry mouth, lightheadedness, and dark urine any darker yellow than lemonade color. In most cases of dehydration, before any heat injury symptoms begin, replenishing with water is the best place to start — and drinking water often! The common recommendation is to drink around 2 litres or 8 glasses of water daily — not taking in to account body size, hot weather, or exercise. What if you drink tons of water, your urine is clear, and you still feel symptoms of dehydration? Electrolytes are different types of salts that bond to water molecules to transport them into blood and then to any cell in the body, or even to transport water out of the body as sweat — think of them as Uber for water molecules! Yes, sodium Na is an important electrolyte, but as are potassium K , Calcium Ca , Magnesium Mg , and Chlorine Cl. Our body loses fluid through exhalation, perspiration, and urination. When training in the heat our body sends triggers to the brain that one is thirsty and should drink. Young athletes already tend not to hydrate themselves properly to begin with so when the weather is colder they tend to drink less during physical activity and increase the risk of dehydration. During exercise and physical activity athletes sweat and during hotter temperatures the sweat is more visible and helps give the athlete a kind of visual cue to drink more fluids. In the cold, athletes still sweat just as much but the sweat tends to turn to vapor in cold, dry air so the athlete does not have those cues and hinder them from hydrating properly because they do not think they need it as much. The athlete needs to know they need to hydrate no matter what. Another form of fluid loss is just through breathing. In cold and dry air our bodies have to work harder to warm up the air we breathe by humidifying it with water in the body. The harder the body works, the more water we lose the more we have to hydrate. We can see some of this water from the body in the form of vapor when the athlete can see their breath in the cold dry air. This contributes to major fluid loss in the body. This is very well known with athletes but this can also tell an athlete how well they are hydrated or not. What may not be known is that in colder weather blood vessels are constricted and moved from the extremities to the core of the body to maintain proper body temps. This can make the body seem as though it is hydrated and not signal to the kidneys to conserve fluids. This in turn causes the body to increase urine output and leading to possible dehydration. If an athlete is taking in enough fluids they should be expelling a normal amount as well. If they are not urinating proper amounts that means the body is not getting enough to replenish what it needs. The color of the urine is also a major factor in determining if the athlete is properly hydrated. Having a urine color chart easily accessible for the athletes to use is very beneficial and allows the athlete to continuously assess their hydration needs. The urine should ideally be a pale yellow and if it is darker the athlete is dehydrated and needs to replenish their fluids. If urine color is very darker yellow or even brownish than they are severely dehydrated and needs proper medical attention right away. The athlete is likely showing other signs of dehydration as well at this point. If the athlete is showing signs and symptoms of dehydration it should be addressed as soon as possible because it could lead to further medical issues. There are ways to combat dehydration in colder weather. Listed are some ways to help reduce dehydration in colder weather:. It is important to let the athletes know that dehydration greatly affects their physical output and endurance during sports. It increases muscle fatigue and can lead to higher risk of injury during physical activity. When an athlete is dehydrated it affects every aspect of their body and its performance. |

The winter season can bring many changes, from the activities we engage in to the foods and beverages we consume. One thing that is important in all seasons is proper hydration. As the temperatures begin to drop, we may not feel as though we need the same amount of fluids as we did in warmer weather. This perception can be due to less perspiration and decreased thirst. However, humans constantly lose fluids through respiration, sweat, and urination, even in cold weather. Aside from feeling thirsty, there are other indicators that you may not be getting enough fluids. These include dark-colored urine, dry or chapped skin or lips, constipation, feeling faint or tired, low blood pressure, and a decreased appetite Roth, If you are experiencing any of these symptoms, it may be time to increase your water consumption. If the symptoms are severe, consult a physician. Proper nutrition and hydration are important to ensure our bodies can generate enough heat to maintain a healthy body temperature as well. Although it may not seem like a cold drink will help keep you warm, hydration is essential to the body's ability to prevent hypothermia. We can get fluid from a variety of healthy sources other than just a glass of water. Broth soups and fruits and vegetables are foods that can provide much-needed fluids to our bodies. Healthy choices of warm beverages include a glass of warm apple cider, warm low-fat or fat-free milk, or a mug of unsweetened hot herbal tea. Our daily fluid needs are typically met by a combination of foods consumed and fluid intake. Fluid needs to increase by 1 to 3 cups per hour during physical activity based on the level of intensity. Older adults may need to be particularly careful to get adequate fluids due to their decreased sense of thirst and ability to concentrate urine. Children's water needs increase with age. Children years old should consume at least 7 cups of fluid per day Ellis, Teen girls should consume at least 10 cups of fluid per day, and teen boys should consume at least 14 cups. Fluid requirements need to be increased if there is fluid loss from sports, fever, or a medical condition. As with adults, ensure these fluids are from healthy sources that are not high in added sugars. Sports drinks are only recommended after significant fluid loss from fever or vigorous exercise of more than an hour. Juice should be limited to no more than one cup per day. Keeping children hydrated even in the winter months will make those outdoor activities like sledding, building snowmen, and waiting for the school bus a little more enjoyable by increasing their ability to stay warm and keep their skin and lips maintaining moisture and prevent chapping. Drinking moderate amounts of coffee can provide some health benefits Klemm, It does supply the body with antioxidants and has been associated with a reduced risk of cardiovascular disease, type II diabetes, and Parkinson's disease. Caffeine can have a diuretic effect on people who do not regularly consume it, though the effect is not as significant in people who regularly consume caffeine. Children and adolescents, pregnant women, and the elderly should limit caffeine due to its stimulant properties. Alcohol is a fluid that may be detrimental to overall hydration and increase a person's likelihood of suffering from hypothermia. Research has concluded that alcohol has been shown to interfere with a person's perception of cold and the initiation of a shiver response Freund et al. The shiver response is activated as a defense mechanism of the body to generate heat and prevent hypothermia. Alcohol acts as a vasodilator which makes the skin feel warm, but it drops the temperature of vital organs and can reduce a person's core body temperature. For this reason, it is important to be mindful of the amount of alcohol we consume and its potential effects on our health during the winter months. Whether one is outside working, hunting, or enjoying other outdoor activities, it is important that we stay warm and hydrated this season. During hot weather you will need to increase your fluid intake, regardless of your activity level. Your level of thirst is not always the best indicator of your hydration status. One of the easiest ways to know if you are meeting your fluid needs is by assessing the color of your urine. Pale yellow urine indicates you are well-hydrated. Honey-colored urine indicates you are dehydrated. Check out the chart above to know what colors to look for. Dehydration can be very dangerous. Other signs of dehydration include: dry mouth, tiredness, dizziness, confusion, muscle cramps, decreased urine output, dry skin, or extreme thirst. There are many types of drinks to choose from to meet your fluid needs; some options are better than others.

Hydration needs during extreme weather conditions -
news Public Health. By Sarah Bahari. Like really , really hot. Yes, a miserable heat wave is roasting Texas and much of the world, exposing millions of people to triple-digit temperatures and elevated risk of heat-related illnesses. Hydration is key to preventing those illnesses, which include cramps, exhaustion and stroke.
On days like Tuesday, when temperatures at Dallas-Fort Worth International Airport reached degrees, those outdoors should be especially mindful. But exactly how much water should we drink? Should we supplement with sports drinks? And is it possible to drink too much water?
Get the latest coronavirus and public health updates. Or with:. By signing up you agree to our Terms of Service and Privacy Policy. In this heat, do not wait until thirst sets in to drink water, said Dr. Children and adults alike need frequent water breaks to combat dehydration.
Adults working or exercising outdoors should aim for an 8-ounce cup of water every 15 to 20 minutes, the U. Centers for Disease Control and Prevention recommends. The bottom line is that both of these physiological mechanisms result in greater fluid loss through urination. When we exercise outside in the winter, we also tend to dress in warm clothes.
Our layers create 'microclimates'. The microclimates both keep us warm and provide a perfect environment for sweating. So, despite the cooler weather, we're still losing reasonable amounts of water through sweating. To further confound the issue, cold weather can suppress our desire to drink.
We're still sweating, yet have a muted thirst sensation. Finally, the body must maintain a core temperature of In cold environments, this becomes harder to maintain. The extra work our body has to do to stay warm results in a greater use of our carbohydrate stores glycogen.
When shivering is required to prevent dangerously low temperatures i. Yes, we sweat more in the summer, but we also lose more water through respiration and urination in the winter. We're also less inclined to take in fluids in the winter even though we're still sweating in our warmer clothing or warm indoor training environment.
That's as a result of the decrease in blood volume mentioned above. The first step in developing an understanding of what you need to be taking in is to measure your sweat rate in different cold weather scenarios to get a rough idea of the volume of your losses in those conditions.
This will help you to better define what you need to be drinking in cold weather you will need to do separate calculations in hot weather as environment does affect your sweat rate. Your sweat rate is one important factor, but your sweat sodium concentration is another - equally important - part of the hydration equation.
Sweat concentration is the amount of sodium you lose per liter of sweat. Because electrolytes especially sodium are important to staying hydrated and maintaining performance, understanding your rate of loss can really help you dial your electrolyte intake in.
Disclaimer: I run PH's Sweat Test Center in Aspen, Colorado. Did I mention that most athletes only need to get Sweat Tested once? That's because your sweat sodium concentration is a largely genetically pre-determined factor that's unlikely to change much during adulthood regardless of training, temperature or altitude.
Another option is to use a few visual indicators to estimate how much sodium you're losing and then take the free Online Sweat Test to get some initial personalized advice and do some trial and error in training before potentially doing the full test to help you refine things down the line.
