Summer Heat Can be Deadly

Summer Heat

According to the Center for Disease Control, heat kills more people than tornados, lightning and floods alone. And they are urging people to stay cool and hydrated this summer. Every year an average of over 600 deaths occur due to extreme heat in the United States. 40% of all heat-related deaths come from California, Arizona, and Texas.

Dehydration in Summer Heat

I learned first-hand how dangerous summer heat can be when I passed out from dehydration in the middle of a summer heatwave while out running. I thought I was drinking enough water before I left the house, but I wasn’t, especially in the middle of a heatwave. Since I didn’t have any way to carry water, I was trying to drink enough to last for a 30-40 minute run. I didn’t think it was that big of a deal, until I found myself passed out by the side of the road. Luckily a Good Samaritan took me to the hospital in time.

This is when I came up with the idea for the wrist water bottle. It supplies 11 ounces of ice cold water to keep you hydrated and it also lowers your body temperature because it’s on your wrist. Drinking a few sips of cold water every few minutes is enough to keep you cool and hydrated.

The summer heat can be especially hard on children and the elderly or anyone with a serious medical condition such as MS. People with MS need to always make sure they are keeping their body temperature down in order to prevent a flare-up of their symptoms. There are numerous cooling products for MS sufferers.

Other things you can do to cool down besides staying hydrated is to wear lightweight, breathable clothing such as cotton, linen, and silk. Keep the air conditioning on and limit your exposure to the outdoors to the early morning and later afternoon hours.

Summer heat is a perfect reason to get outside and get active as long as you avoid overdoing it and keep cool while you’re out there.

Dehydration and Allergies – Is There a Connection?

If you’ve ever had allergies you know how miserable they can be. And the antihistamines you have to take to keep them under control are just as bad, making you drowsy and loopy. During allergy season I have a cabinet full of every all natural solution I can find. Since I was taking so many pills, I had to drink a lot more water with them.

I noticed that when I drank more water the allergies seemed to get a little better. So I was wondering if there was any kind of connection between dehydration and allergies.

Dehydration and Allergies

In the quest for optimal health, we often focus on factors like diet, exercise, and sleep. However, one crucial element that is frequently overlooked is hydration. While most people are aware of the importance of staying hydrated for overall well-being, few realize the significant connection between dehydration and allergies. In this blog post, we will explore the surprising link between these two seemingly unrelated issues and shed light on why maintaining adequate hydration is essential for managing allergy symptoms.

Understanding Dehydration

Before delving into the connection with allergies, it’s crucial to comprehend what dehydration is and how it affects the body. Dehydration occurs when the body loses more fluids than it takes in, disrupting the balance necessary for proper physiological functions. Common causes include inadequate fluid intake, excessive sweating, diarrhea, vomiting, and certain medical conditions.

When the body is dehydrated, it can’t perform optimally. Vital organs, including the skin, lungs, and digestive system, suffer, leading to a cascade of effects that impact overall health. Surprisingly, one of the areas where dehydration can exert a notable influence is the immune system, making it more susceptible to allergic reactions.

The Immune System and Allergies

The immune system plays a pivotal role in protecting the body from harmful invaders, such as viruses, bacteria, and allergens. Allergies occur when the immune system overreacts to a substance that is normally harmless, triggering an inflammatory response. Common allergens include pollen, pet dander, dust mites, certain foods, and insect venom.

In a well-hydrated state, the immune system functions efficiently, recognizing and neutralizing potential threats. However, dehydration can compromise the immune system’s capabilities, leading to an increased risk of allergic reactions. This connection between hydration and allergies lies in the intricate web of immune responses influenced by the body’s hydration status.

Histamine Release and Dehydration

Histamine is a key player in the allergic response. When the body encounters an allergen, immune cells release histamine, triggering inflammation and the classic symptoms of allergies, such as sneezing, itching, and congestion. Proper hydration is essential for regulating histamine levels, as dehydration can lead to an overproduction of this inflammatory compound.

Research has shown that dehydration can stimulate the release of histamine, exacerbating allergic symptoms. In a dehydrated state, cells release histamine as a defense mechanism, even in response to less harmful substances. This heightened histamine release can intensify allergic reactions, making symptoms more severe and harder to manage.

Mucous Membrane Drying and Sensitivity

The respiratory and digestive systems are lined with mucous membranes that act as a barrier against allergens. These membranes need to stay adequately moist to function effectively. When dehydrated, the mucous membranes can dry out, becoming more sensitive to irritants and allergens.

In the case of respiratory allergies, such as hay fever, dry mucous membranes in the nasal passages can increase susceptibility to airborne allergens like pollen. Similarly, in the digestive system, dehydration can lead to increased sensitivity to food allergens. Keeping these mucous membranes well-hydrated is crucial for maintaining a healthy barrier against potential allergens.

Detoxification and Hydration

Proper hydration is vital for the body’s detoxification processes, which play a role in managing allergic reactions. When adequately hydrated, the kidneys can effectively filter out toxins and allergens from the bloodstream, preventing their accumulation and reducing the risk of allergic responses.

Conversely, dehydration can impair the kidneys’ ability to eliminate these substances, allowing them to build up in the body. This accumulation can contribute to chronic inflammation and heightened allergic reactions. Ensuring optimal hydration supports the body’s natural detoxification mechanisms, promoting a healthier immune response.

Hydration Strategies for Allergy Management

Recognizing the connection between dehydration and allergies highlights the importance of adopting effective hydration strategies for managing allergy symptoms. Here are some practical tips to stay well-hydrated and support overall immune function:

Drink an Adequate Amount of Water: Ensure you are drinking enough water throughout the day. The recommended daily water intake varies based on factors such as age, weight, and activity level, but a general guideline is to aim for at least eight 8-ounce glasses of water per day.
Incorporate Hydrating Foods: Include hydrating foods in your diet, such as water-rich fruits and vegetables. Cucumbers, watermelon, celery, and oranges are excellent choices that contribute to both hydration and nutritional intake.
Limit Dehydrating Beverages: Reduce the consumption of dehydrating beverages such as caffeinated and alcoholic drinks. These substances can contribute to fluid loss and exacerbate dehydration.
Monitor Hydration in Allergy Seasons: During peak allergy seasons, be especially vigilant about staying hydrated. The increased exposure to allergens may heighten the body’s need for adequate hydration to support immune function.
Use Humidifiers: In environments with dry air, especially during winter months when heating systems can deplete indoor humidity, using humidifiers can help keep mucous membranes in the respiratory system adequately moist.

Dehydration and allergy connection

In conclusion, the connection between dehydration and allergies is a fascinating and often overlooked aspect of holistic health. Maintaining optimal hydration levels is crucial for supporting the immune system, regulating histamine release, and preserving the integrity of mucous membranes. By recognizing the interplay between hydration and allergies, individuals can take proactive steps to manage their allergy symptoms and promote overall well-being. So, the next time you reach for a glass of water, remember that you’re not just quenching your thirst – you’re also nurturing your body’s defense against allergies.

It’s estimated that at least 75% of the population is in a state of chronic dehydration.

If you are prone to allergies, make sure you are constantly drinking enough water throughout the day. It’s much better to reach for the water bottle than the anti-histamine!

Dehydration and Runners

Water is one of the most important things a runner can consume. About 60% of a runner’s total body weight is water. Water helps maintain body temperature, improve digestion, and helps with circulation and excretion of wastes.

Dehydration and runners

If a runner doesn’t drink enough water, they won’t able to sweat adequately, and this is how body temperature is regulated. If they don’t drink enough water their body temperature will rise. This can negatively impact physical performance and will eventually cause dehydration. Even a very small amount of dehydration can impact a runner’s athletic performance. Thirst is not an indicator of dehydration. Dehydration can happen before an athlete even becomes thirsty.

I found this out when I passed out from dehydration while running in the heat.

The body will pull water from its reserves when it’s deprived of fluids to maintain a safe body temperature. If the body is chronically low on water, a variety of hormonal changes can occur. Extra water should be taken to avoid an imbalance if a runner is drinking alcohol or coffee.

Drink water before, during and after a workout

The small intestine can absorb water at a rate of 8-10 ounces about every 20 minutes. Drinking cold water is better because it will enter the small intestine faster. Take small sips before, during, and after your workout to avoid dehydration. Make sure not to drink large amounts all at once. Spacing out your water is better for the body.

The only way for a runner to prevent dehydration is to make sure they are properly hydrated before, during, and after a training run. Make sure you have water readily available during training and make sure you drink enough water before and after a training run. Know what your sweat rate is. It can be different for different people. Know how much fluid you’ll need to replace. A good rule of thumb is to drink about 20 ounces of water for every pound of weight lost because of sweating.

Try a sports drink for flavor

Some runners think that water is just too plain and boring. If that’s you, try a good sports drink with your favorite flavor. The most important thing is to make sure you replace fluids and stay hydrated.

If you have signs of dehydration, like weakness, headache, thirst, dizziness or chills, not only is your running going to suffer, but you’re putting yourself in danger of a heat related problem. It’s better to avoid that in the first place by making sure you are drinking enough water.

Running and Dehydration

Athletes will go to great lengths to shave seconds off of their running time, and that includes runners. So running and dehydration should be one of the first things to be aware of. As little as 2% dehydration could slow a runner down and have a negative impact on their performance. Studies show that you tend to slow down about 2% for each 1% loss in bodyweight because of dehydration.

Running and dehydration

When the body loses water content and essential body salts, dehydration can occur.

It’s easy for pros and beginners alike to underestimate how much water they need to drink to stay hydrated. Once they get to the point of being thirsty, dehydration is already setting in. 2% of your body weight can be lost before you actually feel thirsty.

Hydrate before training

Marathon trainers will tell you to start hydrating several days before you begin training. Drink more water more often than you normally do. Drink at least sixteen ounces of water or sports drink several hours before you go running and drink a few ounces of water or sports drink at least every fifteen minutes during your run. Drinking cold water will keep your body at a normal temperature.

Symptoms of dehydration

Some of the symptoms of dehydration include:

Thirst, Fatigue, Confusion, Dizziness, Headaches, Dry skin, Skin flushing, Muscle weakness, Increased heart rate.

A good way to determine if you are drinking enough water is by checking urine color. It should be light or clear in color. The darker the urine color, the more dehydrated you are. This is a sign that you need to start drinking more water.

Running in the heat accelerates dehydration. That’s why you need to take precautions to avoid both dehydration and heat stroke. It can take up to two weeks of running in the heat to acclimate your body to the hot temperatures.

Replace electrolytes

Water and electrolytes are lost through sweat and need to be replaced. Essential body salts, such as sodium, potassium, and phosphate need to be replaced. This can be done with a good electrolyte drink mix. It will also improve your performance since it will help to hydrate you better. Sodium replacement is essential for prolonged running.

Sodium helps the body to retain fluid and potassium is essential for muscle and nerve function. The body needs a balance of these to function properly. Too much or too little sodium can be devastating. Too much or too little potassium can seriously affect the nervous system. That’s why you need a good, balanced electrolyte drink.

Running Safety

running safety

Running is basically a safe sport, but there are some things to consider to make sure you are as safe as you can be. I learned the hard way about running safety years ago as I headed out the door on a hot summer afternoon with no water on hand. I passed out from dehydration.

Make sure you are well hydrated

So, the first tip on running safety is to make sure you are hydrated before you head out, and always carry enough water on you. You should drink small sips about every 20 minutes or so. Try using swiggies, wrist water bottles to ensure you have hands-free hydration on the go. They can also be frozen to lower body temperature in the heat and will add a small amount of extra weight.

Carry safety items

Other things you should carry with you are a whistle, cell phone and pepper spray. These are good safety items anyway, but do make sure you have them while running.

Tell others where you will be

Just like when you are hiking or rock climbing, if you are going to be out on a long run, make sure you tell others where you are going and approximately when you’ll be coming home.

Wear reflective clothing

Run facing the traffic so you can avoid an erratic driver. Also, wear reflective clothing if you are running at a time when there isn’t sufficient sunlight. This can be as simple as a reflective vest or reflective tape on your clothes. But do make sure you can be seen in the dark.

Use your intuition

Stay alert at all times and don’t be vulnerable. Stay away from isolated areas or areas you aren’t familiar with. Use your intuition and avoid questionable areas that you just aren’t sure about or trust completely. If you see people that are suspicious, keep a sharp eye out for them. Same with suspicious cars. Practice memorizing license plates (it’s good for your brain anyway!).

Follow these tips and use your common sense while out running to avoid any potential running safety problems.
