3 Signs Of Dehydration To Watch Out For When Exercising

What is Dehydration?

Dehydration is when your body is not getting the water that it needs to perform its proper functions.

When dehydrated, your metabolism will slow down (so that your body doesn't consume the little water it has) and so you'll more prone to gaining weight.

You will also feel weak, and not have the energy and stamina necessary for an effective workout.

So, check out for these 3 signs of dehydration when working out!

Check the toilet

If you’re taking a mid-set break to hit the loo, check on the color of your urine to make sure you’re staying hydrated. When properly hydrated, urine should be pale yellow in color.

Though it may be tricky to keep an eye on it, try to watch the urine stream, since the color of urine will dilute when it hits the toilet water, dark yellow urine may indicate dehydration.

Check your weight

Weigh yourself before your workout – then after your workout as well. For each pound of weight, you lose during your workout, drink 16 oz. of fluid – and if you’ve lost more than 3% of your weight, you may be experiencing significant dehydration, which can result in muscle cramps, fatigue, and dizziness. Keeping a water bottle with you when you workout can help you avoid dehydration.

Stop if you feel dizzy!

Feeling lightheaded during a workout is a sign of dehydration – when there’s not enough water in the blood, both blood volume, and blood pressure drop resulting in dizziness. So, if you feel dizzy – stop and hydrate! And don’t start up again with your workout until the dizziness has passed.


The most effective liquid for preventing dehydration is good old water! Try to sip 7-10 ounces of water every 10-20 minutes during exercise to stay properly hydrated.
