Dehydration occurs when your body consumes less water than it uses. In other words, there is a deficit in fluid intake. Because the human body is more than half water, it is paramount to consume copious amounts of it. We lose water when we perform basic functions like breathing, urinating, and sweating. In severe cases, it can even cause death. The main causes of severe dehydration are fever, vomiting, diarrhea, and a lack of access to drinking water.
There are many symptoms that may be indicative of dehydration. They include an increase in thirst, weakness, dizziness, and fainting. Treatment can include drinking water, an IV, and keeping body temperature in check. If you regularly go long intervals without drinking, make sure to pack water. Keeping well hydrated is beneficial to your health and can keep you feeling more awake.
