How to prevent dehydration 

On extremely hot days, if it’s possible, play sports or spend time outside in the morning and evening when it's cooler. Keep yourself well-hydrated during vigorous sports and activities by:

  • Drinking about 12 to 20 ounces of water before beginning outdoor activities
  • Taking a break every 15 minutes to drink about eight ounces of water or sports drinks such as Gatorade®. Avoid:
    • energy drinks and sodas with caffeine as they can increase dehydration
    • drinks with added sugars
    • alcohol.
  • Wearing light-colored clothing and fabrics that provide moisture wicking and airflow.

Treatment for dehydration

Some medicines such as diuretics, some diabetes medicines and others, can lead to dehydration if you don’t drink enough water with them. Check with your health care provider to see if you are at risk of dehydration due to the medicines you take. 

If you are severely dehydrated, seek medical care immediately at an urgent care or emergency department as you may need intravenous fluids. Dehydration is treated by replacing fluid in the body. In extreme cases you may need IV fluids.
