We all know that water is essential to survival. In fact, most humans can’t survive more than a few days without water. So, when our hydration levels drop, serious side effects like pounding headaches, confusion, and muscle cramps set in. But dehydration is more than just feeling extreme thirst or decreased urination. Not getting enough fluids can dramatically impact your heart health as well.

Here, we’ll show you the connection between dehydration, heart rate, and heart health. You’ll learn how dehydration affects things like heartbeat, blood pressure, and blood fluid volume. Plus, you’ll find out how to recognize dehydration and what causes the condition.

Finally, you’ll discover the most effective way to tackle dehydration is to reach for an oral rehydration solution like DripDrop ORS. It’s medically formulated to crush mild to moderate dehydration, which can cause symptoms including increased heart rate.

Dehydration, Heart Rate, and Heart Health

The main function of your heart is to pump blood to organs throughout your body. To understand the connection between dehydration, heart rate, and overall cardiovascular health, you need to know more about blood. Blood is a blend of liquids — known as plasma — and solids including red and white blood cells and platelets. Plasma is largely made up of water, but it also contains electrolytes and proteins.

Electrolytes are charged minerals and include things like potassium, sodium, and magnesium. Your body uses electrolytes to retain water, produce muscle movements, and send signals across neurotransmitters.

Dehydration is a condition where electrolyte and water loss is greater than electrolyte and water intake. When you’re dehydrated, your body doesn’t have enough water to transport blood efficiently. As a result, the amount of blood – also known as blood fluid volume — in your body drops.

That means your heart has to work harder to pump enough fluids and electrolytes to organs that need them. Your body responds by constricting blood vessels in an attempt to pump the blood more efficiently. The result of this higher cardiac output is an increased heart rate, heart palpitations, and irregular heartbeat.

In addition, dehydration causes decreased blood flow. Without enough fluids, your blood becomes thicker and moves more slowly through arteries and veins. This can cause an increase in blood pressure, particularly if you have high blood pressure or heart disease. The added strain on your heart can also lead to an increased risk of heart problems including hypertension. Blockages in blood vessels can trigger a heart attack or a stroke if they affect arteries that deliver blood to your brain.

In severe cases, dehydration can also lead to low blood pressure. As the condition worsens, your blood volume may drop to dangerous levels. At this point, your heart may not be able to pump enough blood to your brain, resulting in symptoms such as confusion and fainting.

You can’t just drink water to remedy dehydration. You also need to replenish electrolytes to tackle the condition. The best way to do this is to drink an oral rehydration solution like DripDrop ORS. At the first signs of dehydration, start sipping DripDrop ORS. It’s a proven way to manage mild to moderate dehydration that’s powerful enough to use in extreme circumstances but safe enough for everyday use.

Causes of Dehydration

Dehydration and resulting heart rate issues are caused by several different factors. Many people are familiar with high heat and the risk of dehydration. However, the condition can occur just as frequently in cold temperatures. To understand why, it’s important to know what causes dehydration on a biological level. It’s also vital to recognize that other factors, including age and overall health, contribute to hydration status.

When you’re dehydrated, fluid loss is greater than fluid intake and your body doesn’t have enough water and electrolytes. These fluids are essential for bodily processes from sending signals between your brain and organs to maintaining adequate blood volume. In fact, electrolytes such as sodium and potassium play a key role in muscle movement, water retention, and nervous system function.

Even mild cases of dehydration can affect your heart rate. That’s because your body has to work harder to pump blood when you’re dehydrated. As a result, your heart beats faster and your pulse quickens. Here are the main causes of dehydration:

  • Illnesses that cause diarrhea or vomiting
  • Excessive sweating
  • Not drinking enough fluids
  • Electrolyte imbalances
  • Certain medications including diuretics

When you sweat, water and salt are pushed to the surface of your skin where they evaporate to create a cooling effect. If you don’t replace these lost fluids and electrolytes, dehydration can set in. Excessive sweating can also occur in wintertime, not just in summer. With cooler temperatures, we put on heavier clothes and often have to exert more energy when we move. That’s why we’re often drenched in sweat when we shovel snow, go backcountry skiing, or walk several blocks to reach the job site.

When you’re sick, vomiting and diarrhea dramatically increase the speed at which fluids are lost. It can also be difficult to rehydrate when you constantly feel queasy. These two factors combine to increase the risk of dehydration substantially.

Older individuals and young children are at higher risk of dehydration. Young kids are still developing, so even minor changes in hydration status can produce dehydration symptoms. Older adults often take medications or have medical conditions that include dehydration as a side effect. But regardless of age, many of us simply don’t drink enough fluids, which leads to an increased risk of dehydration.

If you feel like you’re suffering from dehydration, there’s a fast, low-cost way of managing the condition. Reach for an oral rehydration solution like DripDrop ORS. It contains a precise balance of glucose and electrolytes, including sodium, to tackle dehydration — which can cause symptoms like increased heart rate or irregular heartbeat — quickly.

How To Recognize Dehydration

Now you know the connection between dehydration, increased heart rate, and what causes the condition, it’s time to understand how to recognize the symptoms of dehydration. Once you can identify the main indicators of dehydration, you can jump into action to prevent the condition from worsening.

One of the easiest ways to tell you’re dehydrated is to look at the color of your urine. Dark urine or decreased urination for several hours are key indicators of dehydration.

Here are some other warning signs of dehydration for mild to moderate dehydration:

  • Extreme thirst
  • Dry mouth or dry skin
  • Increased heart rate (known as tachycardia)
  • Rapid breathing
  • Headache
  • Decreased urination
  • Blood pressure changes
  • Dizziness
  • Lightheadedness and fatigue
  • Muscle cramps
  • Increased body temperature

Cases of severe dehydration may include fainting, confusion, and irritability and should be treated by a qualified medical professional.

If you recognize the symptoms of mild to moderate dehydration, drinking plenty of water isn’t enough to beat the condition. That’s because dehydration isn’t just about drinking water. You also need electrolytes to ensure your body functions properly.

Regardless of how mild or severe, when you're in a state of dehydration, drinking a few glasses of water is not enough. Your body needs the perfect balance of sodium and glucose to help absorption. With the precisely balanced ratio provided by oral rehydration solutions like DripDrop ORS, you can replenish vital electrolytes and fluids to relieve dehydration quickly.

Plus, DripDrop ORS supplies vitamins like zinc, potassium, and magnesium, which are essential to support your overall health. The convenient packaging means you can take a high-quality dehydration protocol with you everywhere you go.
