This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am 37 years old, and my weight is 136 pounds. I am a healthy woman, but I wish to know about the amount of water intake per day. I have come across the terms dehydration and water intoxication, and I am worried.

  1. How much water do people like me require?
  2. Is it not enough to take water whenever one feels thirsty?
  3. How much water should I be taking per day?
  4. Would an excess of it cause intoxication?

Please advise.

Hello,

Welcome to icliniq.com.

I can understand your concern.

It should be understood that the requirement for water is not universal but depends on factors including age, body weight, activities, and climatic conditions. For example, the National Academies of Sciences, Engineering, and Medicine suggests daily intake of 125 ounces of fluids by men and 91 ounces by women.

Still, it is possible to state that, in general, you should drink about 30-35 milliliters of water for each unit of your weight in order to understand and satisfy your hydration requirements.

Increased water consumption is necessary for people who lead an active life due to increased losses of liquids during perspiration. Also, factors like high humidity and temperature, diets rich in salt or proteins, can require a larger amount of water. Water is an important part of our health and has an important influence on our well-being.

Water intoxication arises as a result of increased consumption of water that leads to decreased levels of sodium in the blood, resulting in symptoms such as headaches, nausea, confusion, seizures, and even coma.

In order to prevent water intoxication, the following tips are suggested:

  1. Drink water slowly during the day rather than drinking huge amounts of water at once.
  2. Drink water according to your thirst and balance your water and electrolyte intake.
  3. A good pale yellow color of urine shows that you are well hydrated, but dark yellow indicates that you should consume more liquids.
  4. It is also necessary to drink water while eating to have a constant water supply.
  5. Use of a water bottle will remind you to drink water.

I hope this helps.

Thank you.
