You’ve likely seen it in the news; we are experiencing record levels of heat this summer, especially here in the Southwest and West Coast. Many of us are living are day-to-day lives in triple-digit heat, which may require us to shift some of routines and activities to accommodate this inclement weather. Limiting outdoor time, using UV protective products, and prioritizing hydration are just a few ways to make sure you are safe and healthy during the summer. 

But what about when these things are not possible? When you have to be out in the sun for prolonged periods of time? Or when you don’t have access to water? How do you know if you’re experiencing dehydration?

Read on for some key indicators that your body is experiencing dehydration.

Dry mouth and skin

As the body becomes increasingly dehydrated, the blood vessels to the skin and mucous membranes become tightened to conserve body water, leading to skin, lips, and mouth feeling dry. 

Dark urine 

The more dehydrated you are, the less urine your kidneys will produce in order to conserve energy. This leads to your urine becoming more concentrated. As the urine becomes more concentrated, its color becomes increasingly dark (or even non-existent if you are severely dehydrated).

Fainting and light-headedness

When the heart does not have enough fluid, the amount of blood which can be ejected per unit time is decreased. This drastic decrease in cardiac output can lead to low blood pressure and low perfusion of the brain, causing a feeling of light-headedness, dizziness, or fainting/passing out.

Fatigue

Chronic dehydration can lead to persistently lowered cardiac output, leading to decreased tissue perfusion, and feelings of tiredness, fatigue, decreased energy, or listlessness. 

An IV can resolve many of these symptoms in as little as thirty minutes! If you suspect your dehydration is severe, it is recommended you call 911 or seek emergency medical care. Signs of severe dehydration include disorientation or confusion, rapid heartbeat and/or breath, fever or unconsciousness.
