The hot Florida summer is approaching, and we all need to make sure we focus on hydration in the heat. Dehydration is very common in hot, humid environments. Many people do not drink the recommended amount of water. Many of us have our coffee in the morning and unless we go out to lunch and someone gives us water, we seldom think about water during the day. Another confusing concept is how much water we should drink. Growing up, we were told to get eight glasses of water a day. That is 64 ounces. Let’s see if that adage still holds true today.

How much water should I drink?

The best way to calculate how many ounces of water to drink is to multiply your weight by .67 or 67%. For example, a person weighing 150 pounds would need 100½ ounces or a little over 12½ cups. On the other hand, a person weighing 200 pounds would need 134 ounces or 16¾ cups.

Is that all the water I need?

No, as you sweat, you lose the water you have already consumed. If you are sweating for 30 minutes, you need to replenish your hydration with 12 additional ounces of fluid.

What fluid should I drink?

The main thing to remember when it comes to hydration is, just because it is wet does not mean you are being hydrated. Different fluids are absorbed by our bodies differently. Some alcoholic beverages remove hydration from our bodies as we drink them. Below is an example of how our bodies absorb some common beverages:

  • Water absorbed at 100%
  • Sparkling Water absorbed at 100%
  • Skim Milk absorbed at 90%
  • Buttermilk absorbed at 90%
  • Whole Milk absorbed at 80%
  • Apple Juice absorbed at 88%
  • Decaffeinated Coffee absorbed at 90%
  • Coffee absorbed at 80%
  • Sports Drinks absorbed at 50%
  • Energy Drink absorbed at 40%
  • Wine absorbed at negative 150%
  • Beer absorbed at negative 60%
  • Sake absorbed at negative 180%

This is a huge concept to grasp if you plan on being out at the beach with your friends this summer. With this example, a well-hydrated 150-pound person consumes the required 100½ ounces of fluid. Then, at a gathering, they have three glasses of wine. The standard five ounces per glass would mean they have removed 22½ ounces from their hydration after drinking only 15 ounces of wine. Be cognizant of what you add to your coolers this year.

What are the signs of dehydration?

There are many signs our bodies will give us to signal dehydration. Headache, nausea, and muscle pains are common. However, the most common sign of dehydration is thirst. That’s right, if you are thirsty, it is your body’s way of letting you know you need fluids. Just be careful which fluids you choose this summer when you are out enjoying the Florida sun.

Tips for Staying Hydrated

How to Stay Hydrated

Here in the Panhandle of Florida, we are starting to get into the heat of the summer. With temperatures soaring, your sweat is going to start pouring. It is extremely important to replace the fluids lost through sweating. In this article we will cover what hydrated versus dehydrated means, why it is important, and tips on how to stay hydrated in the Florida heat.

What is Hydration, and Why Does it Matter?

Hydration is the process of introducing our body to additional fluid (i.e. water). Dehydration is when you have used or lost more fluid than you are taking in. Your body is unable to continue functioning properly without fluids. Staying hydrated may seem like a difficult task, but it is extremely important for us to stay hydrated for optimal health and performance throughout the day. “Drinking enough water each day is crucial for many reasons: to regulate body temperature, keep joints lubricated, prevent infections, deliver nutrients to cells, and keep organs functioning properly. Being well hydrated also improves sleep quality, cognition, and mood.” (1) Without staying hydrated, we can seriously harm ourselves. Whether you are considered a youth or an adult, you can still lose approximately 40 percent (2) of your body’s water during hard work or exercise.

How to Stay Hydrated

Drink lots of fluids: Do NOT wait till you feel thirsty to drink. By the time you feel thirsty, you are already slightly dehydrated. It is important to drink fluids, preferably water, throughout the day. During the summer, while it is hot, it should be a top priority to replenish lost fluids in our body. A good way to start the day is by drinking a glass of water when you wake up and get your body going. Some fluids are better for us than others. When replenishing fluids lost through sweating, make sure that it is mainly from water. Some of the fluids can also be from flavored water, tea, or coffee. Try not to consume as many sugar-sweetened beverages, as many of them act as a diuretic. The sugar found in these drinks tends to draw the water out of your cells, making you feel thirsty a short time after drinking it. The sugar drawing the water out of cells will also make you need to urinate more quickly, therefore losing even more fluid. Something “punny” – No matter how much soda I drink, I’m still so thirsty… I must be “soda-hydrated!”

Eat Fuel Foods: Make sure you are fueling your body with the appropriate foods. Certain fruits and vegetables contain a large amount of water. Examples of water-rich fruits are: watermelon (it’s in the name!), strawberries, peaches, and pineapples. Some examples of vegetables with a high water content are: Cucumbers, leafy green (i.e. lettuce), celery, and tomatoes. Foods that are highly processed tend to be dehydrated and have lots of sugar or salt, which dehydrates you more.

Look at the Weather: Stay inside when it gets too hot outside and when it is extremely humid. The sun is at its peak between 10 am and 2 pm every day, meaning that time is when it will be hottest outside. Plan necessary outdoor activities for the early morning or later in the evening. Also, the higher the humidity, the more you are going to sweat.

How to Dress: Make sure that you dress for the weather, appropriately. Loose fitting clothing allows your skin to breathe, keeping your body cooler. Lighter shades do not absorb the heat like dark colors. Wear a wide brimmed hat to keep your head cool. Also, use plenty of sunscreen. Getting sunburned is not just uncomfortable, it can also increase your skins’ temperature, making it hard to stay cool.

Signs of Dehydration: Be aware of the signs of dehydration. As stated above, do not wait for the signs of dehydration to begin drinking fluids. Some of the signs of dehydration include but are not limited to: dark or smelly urine, vomiting, bad breath, dry mouth, irritability, confusion, and fatigue.  If you are dehydrated or have lost a lot of fluid through sweating, vomiting, or diarrhea please seek medical attention.

Some Tips for Staying Hydrated

I have a hard time getting myself to drink plenty of fluids, so below are a few tips that I try to follow to keep myself properly hydrated.

  1. Keep a bottle or glass of water by your bed. While you are sleeping, your body is not receiving any fluids, so it is becoming slightly dehydrated. Having water close by the bed means you do not have to get up and disrupt your sleep.
  2. Purchase a reusable water bottle. If you have a reusable glass or metal water bottle, you can keep it with you all the time. If you have easy access to water, you are more likely to drink it.
  3. Flavor your water. Plain water can become boring if you drink it all the time. Flavor your water with some fresh fruit or a flavoring packet.
  4. Try to drink at least 8 glasses of “good” fluids every day. Water is extremely good for you, but you can also consume clear broth, tea, coffee, or sports drinks. This will help prevent water from becoming boring. Just make sure that you limit the intake of caffeine and alcohol.
  5. Check the color of your urine. Believe it or not, this can be a good indicator as to whether you are hydrated or not. The paler, or clearer, your urine is, the more hydrated you are. If the urine you pass is darker, yellow or even orange, you are more than likely dehydrated.
  6. Download an app. There are apps on our phones for everything now-a-days. There are apps that can send you notifications to drink more water. Some of these apps are also capable of recording how much you drink.

Staying hydrated is extremely important, especially now that we are facing the “dog-days” of summer. Drink lots of fluids, but do not wait till you feel thirsty. The more that you sweat, the more fluids you need to take in.

Avoid the Dangers of Dehydration this Summer

Avoid the Dangers of Dehydration this Summer

Stay hydrated this summer.

Nothing is more refreshing on a hot summer day than an ice-cold glass of water!  Water is an essential component to good health. In fact, it makes up 60% of your body’s weight and is involved in various metabolic processes throughout your body. Without it, you could not survive. As summer approaches, it is important to be mindful of the increasing temperatures outside since the chances for dehydration are much greater than other times of the year – especially if you are planning to spend a lot of time outdoors.

Dehydration happens when your body lacks enough water to carry out normal processes. It often occurs when you are expending more water (usually through sweat & exercise) than you are consuming, and is accelerated in warm humid climates. Dehydration is no joke, and can lead to serious medical complications such as heat stroke, heat stress, and even death. Common signs and symptoms that may indicate you are dehydrated include fatigue, headache, dry mouth, little to no urination, constipation, vomiting, muscle-weakness, dizziness, and lightheadedness. Most susceptible to heat stress and complications from dehydration include infants, older adults (65 & up), people who are overweight, and people who are excessive sweaters during physical activity. If you fall into any of those categories, try to be mindful about how much fluid you are consuming throughout the day.

How can you prevent dehydration?

While many people think they may be drinking enough, that is often not the case. Your own thirst mechanism isn’t always the best gauge to make sure you are properly hydrated. According to the National Academy of Medicine, women should consume an average of 9 ½ cups of water per day and men should be consuming 12 cups. For older adults over the age of 70, the rule of thumb is about 7 cups per day. That includes all fluids from water, coffee, and juices.

Keep in mind that needs may be different for each of us.  One simple way to check your hydration status is to look at the color of your urine. If the color of your urine is a light lemonade color, you are in the clear! However, if your urine color is a dark orange, you need to start drinking some fluids to get back to a hydrated state to avoid any health complications.

Additional ways to reach your fluid intake without refilling your water bottle

Did you know water makes up the largest component of many of the foods we eat? By adding some more fruits and vegetables to your diet such as watermelon, strawberries, melons, oranges, broccoli, bell peppers, and lettuces – you are not only increasing your fluid intake but getting your necessary vitamins and minerals as well!  According to the Dietary Guidelines for Americans, people should be consuming an average of 2 cups of fruits and vegetables per day.

Other factors that can influence your hydration status

Alcohol – Alcohol acts as a diuretic – meaning it turns down a hormone called antidiuretic hormone (ADH) which tells your kidneys to absorb/retain fluids.  In other words, drinking a lot of alcohol will make you expel more fluids from your body.  Make sure to drink extra water while enjoying alcoholic beverages to avoid becoming dehydrated.

Diet – Consuming a high-sodium diet is another cause of dehydration. Sodium is necessary in our diets, but only in very small amounts.  When we consume excessive amounts of sodium, this disrupts the body’s filtration system and the kidneys begin holding onto more and more water.  This leads to dehydration, bloating, edema, hypertension, and cardiovascular stress. Drinking extra water can help bring things back into balance and re-hydrate your thirsty cells!

Older Age – As we get older, thirst sensations decrease and risk for dehydration increases since older adults do not feel the need to drink as much. Additionally, many medications can influence fluid needs in the body.

Caffeine – Contrary to popular belief, caffeine does not dehydrate you. When you drink coffee, or other caffeinated beverages you are also consuming fluids. High fluid consumption leads to higher frequency of urination.

Learn to LOVE Water  

Water by itself can definitely get old if it isn’t your beverage of choice. There are plenty of ways to add flavor and sweetness to your drinks without packing in tons of extra calories and sugar. Fruit infusions are a very simple way to make a boring beverage much more delicious. Try some of these delightful, thirst-quenching recipes!

Water:  Myth or Fact?

Water: Myth or Fact?

Carry water with you to sip throughout the day

Summer has arrived!  During the summer months, especially along the Gulf Coast, it is hot and humid.  Keeping the body hydrated is important to maintaining good health.

As the temperature rises in the summer and the body loses more water through evaporation and perspiration, it makes good sense to increase your intake of fluids.  Keep in mind that by the time you notice you are thirsty, you have already depleted your water stores dramatically.  A good rule of thumb is to drink a few ounces of water every fifteen to thirty minutes when you are working or playing hard in the heat.

  • Myth or Fact – You should drink at least eight glasses of water a day.

Myth – On average, the body requires a half gallon of water daily.  That’s the amount required to replace what has been lost through perspiration, evaporation, and body waste.  Milk, juice, and other fluids can be added to your daily total.  Beverages that contain caffeine, such as coffee, tea, and soft drinks, are not good substitutes for water.  Caffeine actually may cause the body to lose water.  The same is true for alcoholic beverages.  They contribute to water loss, not gain, because alcohol acts as a diuretic.

  • Myth or Fact – All water is the same.

Myth – The following guide will help you navigate the sea of choices available:

  • Distilled Water – is pure water with no added chemicals or minerals.
  • Mineral Water – is available in canned or bottled varieties. Many brands include a mix of minerals to improve the taste.  Natural or artificial flavors, such as lime or lemon, may be added to some.  Some varieties add sugar.  Check the label.
  • Soft Water– commercially softened water often is treated with salt and tends to be high in sodium.
  • Sparkling Water– some sparkling waters contain bubbles naturally; others are created with the addition of carbon dioxide.
  • Well Water – is more commonly known as tap water.

 

  • Myth or Fact – Increasing daily water and fluid intake is difficult.

Myth – Actually, there are a variety of ways to increase water and other fluid intake.  Purchase a insulated water bottle and refill it throughout the day.  Add flavor to water.  Infused water is becoming a popular food trend.  Infuse with strawberries, lemons, limes, or other flavorful fruits and vegetables.  Choose foods that contain high levels of water content – for example, watermelon, grapes, and kiwi.  Start the day with a glass of water at breakfast.

  • Myth or Fact – Water aids in bodily functions.

Fact – Water contributes about sixty percent of an adult’s body weight.  Staying hydrated may be a major benefit to increasing energy production.  Increased water consumption can aid in weight loss.  Water aids in the body’s temperature regulation, acts as a lubricant, and cushions around joints.  Water serves as a solvent for minerals, vitamins, amino acids, and glucose.   Because water is vital to bodily functions, the body directs many of its activities toward maintaining balance.

  • Myth or Fact – You can drink too much water.

Fact – Over-hydration can result in water intoxication.  Water intoxication occurs when you consume more water than the kidneys can excrete.  Consuming large amounts of water in a short period of time can result in intoxication.  Remember, you should drink at least eight glasses of water a day – it’s a fact.

Chill Out in the Summer Heat

Brutal … Sizzling … Searing.  These words are often used to describe the summer heat in our Southern region of the U.S.  While staying cool in the summer heat is a matter of comfort for most of us, for many folks, excessive exposure to heat can be very dangerous.  Here are some easy-to-follow tips to stay cool and prevent heat-related illnesses during the hot summer months.

Create a cool breeze with a fan blowing over a bowl of ice.

Create a cool breeze with a fan blowing over a bowl of ice.

  1. Drink and eat plenty of fluids.  Drink lots of cool water to increase your fluid intake regardless of your physical activity level.  For something different, add a wedge of lemon or lime.  Watch out for sugary drinks that can add up to unnecessary calories.  Do avoid very cold drinks, though, as they can sometimes cause stomach cramps.  Instead of hot foods, eat lighter summer fare which includes frequent small meals or snacks containing low fat dairy products or cold fruits and vegetables.  Try starting the day off with peaches, plums, melons, pears, and cooling citrus.  Include salads in your diet.  Leafy lettuce and summer greens, cucumbers, and corn on the cob in salads are a tasty way to stay cool since these foods contain a significant amount of water.  Fill ice cube trays with fruit and 100% juice and freeze for a tasty cooling treat that is both nutritious and delicious.
  2. Wear lightweight, loose-fitting clothing.  Choose light-colored clothes, since they reflect more rays than dark colors do.  In the hot sun, wearing a wide-brimmed hat will help to keep your head cool.  Wear cotton rather than synthetic fabrics.  Since cotton is absorbent, it dries quickly and wicks away the sweat.  Avoid shoes that trap in heat and sweat.
  3. Use a buddy system for work and play.  When you are working in the heat, monitor your coworkers’ condition and have someone do the same for you.  For information on keeping hydrated in hot working environments,check out Hydration in Hot Working Environments.  If you are over 65 years of age, have someone check in on you twice a day.  If you know anyone in this age group, check on them at least twice a day.  Run through the sprinklers with friends like when you were a kid – or start a water balloon fight.  Who cares what the neighbors think?
  4. If you do not have air-conditioning, try to spend at least parts of your day in a shopping mall, movie theater, public library, or other public space that is cool.  Chill down a fan one more notch by putting a bowl of ice in front of the fan to ensure extra cold air.  Try storing lotions or cosmetic toners in the refrigerator to use on hot, tired feet.
  5. Finally, if the heat is unbearable, stay indoors when you are able and avoid activities in direct sunlight or on hot asphalt surfaces.  Pay special attention to infants, the elderly, and anyone with a chronic illness, since they may dehydrate easily and be more susceptible to heat-related illnesses.  Certain medications also can increase sensitivity to the heat; check with your doctor or pharmacist to see if you need to stay out of the sun.  Don’t forget that your pets need protection from dehydration and heat-related illnesses, too.  For answers to Frequently Asked Questions about Extreme Heat, visit http://www.bt.cdc.gov/disasters/extremeheat/faq.asp.

This summer, don’t get too heated – chill out!
