If you were a glass of water, you'd be more than half full.&nbsp;At least, you should be.
Water makes up more than 50% of your body. Three-quarters of your muscle tissue and 10% of your fatty tissue are composed of water, according to the&nbsp;<a href="https://azblue.netreturns.biz//healthinfo/bouncelink.aspx?shortcut=ace" target="_blank">American Council on Exercise</a>&nbsp;(ACE).
But your water content isn't a constant: You lose water with a number of different activities every day, especially when exercising and during warmer weather.&nbsp;To stay hydrated, you need to be sure that you take in as much water as you lose.
Why water is important
Since your body is mostly water, you obviously can't live without it. Water regulates your body temperature through sweat. When you get hot, sweating cools you down.&nbsp;It also protects your organs and helps your digestion. Your body's cells need water to transport nutrients and get rid of waste.
Water does more than cool us down and flush waste from our bodies. <a href="https://library.azblue.com/health-library/story/2ac52b7e-4575-4497-aed5-fd3323af0e78" target="_blank">View this infographic</a> to learn why you should choose water the next time you&rsquo;re feeling thirsty.
The dangers of dehydration
Like a car with an empty radiator, a dehydrated body becomes overheated. Although smoke won't start billowing from the top of your head, you are putting yourself at risk for:
Heat cramps.&nbsp;These are painful muscle contractions, often in the abdomen, arms or legs.
Heat exhaustion.&nbsp;This is the body's response to an excessive loss of water and salt. It can cause symptoms such as heavy sweating, extreme weakness, dizziness, irritability and nausea.
Heatstroke.&nbsp;This is the most serious heat-related disorder, according to the&nbsp;<a href="https://azblue.netreturns.biz//healthinfo/bouncelink.aspx?shortcut=cdc" target="_blank">Centers for Disease Control and Prevention</a>&nbsp;(CDC). It can cause death or permanent disability if not treated right away. During heatstroke, body temperature rises rapidly, sweating stops, and the body is unable to cool down. According to CDC, symptoms include:
<ul>
 <li>Hot, dry skin or extreme sweating.</li>
 <li>Coma.</li>
 <li>Seizures.</li>
 <li>Extremely high body temperature.</li>
 <li>Confusion.</li>
 <li>Slurred speech.</li>
</ul>
Stay hydrated, stay healthy
Most people can let thirst be their guide to staying hydrated, according to the&nbsp;<a href="https://azblue.netreturns.biz//healthinfo/bouncelink.aspx?shortcut=iom" target="_blank">Health and Medicine Division of the National Academies of Sciences, Engineering, and Medicine</a>.
But thirst is a sign that you're already on the way to dehydration, according to ACE. To stay healthy, you may need to do more than just quench your thirst.
Drink extra when you exercise.&nbsp;ACE offers these guidelines:
<ul>
 <li>Drink 17 to 20 ounces of water two hours before exercise.</li>
 <li>Drink 7 to 10 ounces of fluid every 10 to 20&nbsp;minutes during exercise.</li>
 <li>Weigh yourself before and after workouts. Drink 16 to 24 ounces of fluid for every pound you lost during exercise.</li>
</ul>
Other tips to stay hydrated include:
<ul>
 <li>Drink small amounts often instead of large amounts rarely</li>
 <li>Drink cold beverages to cool your body down</li>
 <li>Watch for small amounts of urine or dark-colored urine, which can be a sign you aren't drinking enough water</li>
</ul>

Drink up! Making sure you get enough water
