Hot temperatures can increase the risk of dehydration, which occurs when the body loses more fluids than it takes in, disrupting the body’s natural balance of fluids and electrolytes. While dehydration can be caused by lack of fluid intake or excessive sweating, it also can be triggered by excessive vomiting, diarrhea, or fever. It can affect anyone, but older adults and people with certain medical conditions may be at greater risk.
Mild dehydration often includes symptoms such as dry mouth, increased thirst, headache, infrequent urination, and dark-colored urine. Typically, mild dehydration can be managed by drinking water or beverages with electrolytes. Severe dehydration requires immediate medical attention and may include symptoms such as confusion, dizziness, sunken eyes, rapid heart rate, and lack of sweating or urination.
To help stay hydrated, drink fluids regularly throughout the day, even when you don’t feel thirsty. Eat water-rich foods like fruits and vegetables, and limit your alcohol consumption, which can contribute to dehydration. As a good rule of thumb, keep a bottle of water nearby to sip from throughout the day.
