Thank goodness we made it through the cold winter! I’m proud of all of us for enduring to warmer months, it is so worth it now. Summer gets hot, we all know that. Summer is also a great time to go outside and be active. The problem with the combination of those two great things is that it is very easy to forget about dehydration within the body. 

Dehydration is when your body cannot maintain the needed water levels to function. It happens as you don’t replenish lost fluids. Sweating is great because it keeps you cool, but you also need to drink water to help keep your hydration levels normal.

The big problem with dehydration is it causes a lot of other problems. It will make you feel sick, tired, lightheaded, etc. There are other medical issues that arise as a result of not staying hydrated. 


Cramps are sudden contractions of your muscles as a result of not having enough water or minerals, or from holding a position for too long. When your muscles cramp, they can sometimes be massaged and worked back into their relaxed state fairly easily.

Other times it’s hard because of the muscles contract due to lack of water, so until they get the hydration they need, they are going to give you issues. Even if you get it to stop cramping, it very well may start again soon.


Have you ever come back from exercising with a massive headache? It likely means you are dehydrated. The exertion and lost fluids can cause the pain to begin.

It can also result from the brain shrinking slightly due to lack of fluids. That just sounds all-around bad, so let’s try to avoid that.

Kidney stones form when there is not enough liquid moving through your urinary system. It allows minerals to calcify, forming little “stones” in your urinary tract. Drinking plenty of water can help prevent the minerals from being left behind to form the stones.

Heat Exhaustion

Heat exhaustion is when your body can’t effectively cool itself down, and starts to overheat as a result. It will make you very tired, likely cause headaches, and can lead to far worse heatstroke.

Dehydration causes your body to not be able to sweat as much, or at all. This causes your body’s temperature to rise with no way of cooling you down. It is important to drink water and go sit in a cool shaded place to recover. Medical attention may be warranted depending on the severity of the heat exhaustion. 


Heatstroke is among the worst heat-related injuries, if not the worst. It is similar to heat exhaustion in that it starts when your body cannot cool down. Heat-related injuries are classified as heatstroke when a person’s body temperature exceeds 104 degrees Fahrenheit. 

Heatstroke a be deadly. If it is not immediately treated it can cause damage to the brain, heart, other organs, and muscles. Always seek medical attention if you think there is even a chance this is happening. 


Heat injuries are nasty. Dehydration is a huge risk factor in all of them. Make sure you drink plenty of water to keep your body hydrated and functioning properly. We made it to summer, now go enjoy it safely!
