3 Signs Youre Dangerously Dehydrated

You know you need to drink water when you start to feel thirsty. Learn the other, less obvious signs of dehydration you should watch for.

It’s critical to stay hydrated when you work out—especially during the summer months. These 3 signs can help alert you that you could be dangerously dehydrated.

  1. An elevated heart rate
    Your pulse will rise naturally with exercise. However, if your pulse is 15-20 beats above your target, your heart could be compensating for reduced blood volume by beating faster.

  2. Dizziness
    If you’re dizzy when you move suddenly or change positions, blood might not be reaching your head quickly enough due to low blood volume.

  3. Sagging skin
    To test your skin turgor for dehydration, simply pinch the skin on the back of your hand. If it doesn’t snap back into place immediately, you need more fluid.
