Water is one of the most critical components of the human body. Seventy-five percent of our muscle tissue is made up of water. It regulates body temperature, protects vital organs, and aids the digestive system. Water also transports nutrients and helps remove waste from the body. As you can imagine, being well hydrated is important and dehydration can lead to serious health problems. The best way to approach dehydration is to prevent it.
Here are some tips to help you prevent dehydration.
- Keep a refillable water bottle with you all the time. Fill it up before you leave home and familiarize yourself with the water refilling stations on campus.
- Check the weather forecasts for high heat index days and schedule your outdoor activities in the cooler hours of the day.
- Limit alcohol consumption. Alcohol increases water loss and impairs the ability to recognize early signs of dehydration.
- Thirst is the first sign of dehydration. If you are thirsty, take the time to drink water without delay.
