Factors such as physical activity, temperature, humidity, and overall health can also affect how long a person can survive without water. Additionally, if a person is exposed to extreme temperatures, such as a hot desert, they can die within a few hours without water.

Why Does The Period Of Time That You Can Live Without Water Vary?

The period of time that you can live without water is generally 3-4 days.  However, this time frame varies because the body is constantly losing water through activities such as urination, sweating, and respiration.

What Can Help Improve The Chance Of Surviving Without Drinking Water?

  1. Eat foods with high water content: Fruits and vegetables are good sources of water. Eating foods like lettuce, celery, watermelon, cucumbers, and tomatoes can help keep you hydrated.
