You may have heard claims like, "Drink eight glasses of water a day," or "Drinking more water can help you lose weight, detoxify, and moisturize your skin." Dr. Eric Berg explains that many of these claims are incorrect and may even be harmful to your health . Here's a complete breakdown:

 Debunking Common Drinking Water Myths

"The human body is 60% water"?

In fact, the human body is not composed of "pure water", but rather of body fluids containing electrolytes (such as blood, lymph, and urine), which contain minerals such as sodium, potassium, and calcium.

"The body doesn't know it's thirsty"?

Wrong! The human body has more than 50 senses, including hunger, thirst, and temperature sensitivity. Thirst is the body's way of reminding you that you need to drink water.

"Drinking water can help you lose weight"?

Fat is not water-soluble, and drinking water will not dissolve it. Try rinsing fatty bacon with water, and you'll find that the fat won't dissolve at all.

"Drinking water can detoxify"?

Most toxins (such as pesticides and drugs) are fat-soluble, not water-soluble. Drinking water cannot "wash away" fat-soluble toxins.

"Drinking water can improve dry skin"?

Dry skin is mostly caused by a lack of fat-soluble vitamin A , not by a lack of water. Skin, eyes, mouth, and joints are lubricated by oils, not water.

 Risks of excessive water intake: Hyponatremia (water intoxication)

  • Drinking too much water electrolytes are washed away cells swell
  • Potential side effects include: brain swelling, coma, cardiac stress, hepatomegaly, and cramps.
  • Overhydration during exercise , especially long-distance running/marathon , increases the risk of water intoxication.

 Symptoms of overhydration

  • Headache worsened
  • body temperature rise
  • Swelling of hands and feet
  • Mental confusion/fatigue

Correct drinking water principles

  • If you're not thirsty, don't drink your body will regulate itself.
  • Drinking less leads to less urination; drinking more leads to more urination.
  • Recommendation: Drink water based on your thirst, rather than rigidly adhering to "eight glasses a day".

 Recommended reading: * Waterlogged * by Tim Noakes

  • Dr. Tim Noakes, a leading authority in sports medicine, points out:
    • Overhydration is more dangerous than dehydration
    • Water intoxication is more common in athletes than dehydration.
    • Thirst = the most accurate indicator of hydration

 In conclusion: Don't be trapped by "drinking myths" anymore; knowing how to drink right is the key to true health.

Starting today, we'll help you establish a solid foundation for your health with a drinking habit based on your body's perception, a hydration strategy to avoid water intoxication, and a health mindset based on electrolyte balance!

Don't be misled by the myth that "eight glasses of water = health." Only by knowing how to drink correctly, replenish properly, and nourish deeply can you achieve true health!
