Extreme Thirst
Sleepy
Sure, summer and the heat call for lazy days. But if you're always feeling sleepy, possibly borderline lethargic, it might not be the heat. It may be that you're dehydrated. Try upping the amount of water you drink. Your body is telling you something.
Can't Pee
Haven't peed in awhile? That might be because your body has run out of excess fluids. You should being going six to eight times a day. Up to 10 times is also totally healthy and a sign that you're hydrated.
Dark Yellow Urine
If your urine is a little darker yellow than usual, and you have no other health problems, this could be a sign that you're dehydrated. Often, bathrooms aren't easily available around summer hot spots, like the pool, the beach or while traveling abroad. But don't use that as a reason to decrease water intake. You need to stay hydrated.
Headache
Many people experience headaches when they haven't managed their daily water intake. Before taking medication or jumping to more serious conclusions, try drinking more water throughout the day to get rid of the headache. Going forward, stay on top of hydration, since headaches are a symptom of dehydration.
Skin Has Lost Elasticity
Depending on where you live, heat can take a toll on skin, drying it out and zapping it of its elasticity. It's also a symptom of being constantly dehydrated. Also known as skin turgor, if you can pinch your skin and it stays tented for any degree of time, you might be experiencing dehydration, according to the National Institutes of Health.
Dizziness
The Mayo Clinic lists dizziness as a symptom of dehydration, too. Without enough fluids in the body, brain function can be compromised. This is especially a problem for young children and older adults. If you stand up and feel unsteady, consider whether you've had enough water recently.
