JL Górriz, nephrologist: “When we drink a lot of water, sodium dilution is lower and hyponatremia occurs”

For decades, water has been hailed as one of our greatest allies in health. It keeps us hydrated, helps transport nutrients throughout the body, regulates temperature, aids digestion, and even prevents constipation. But as with many things, too much of a good thing can turn harmful.

That was the focus of a recent episode of Tus Amigas Las Hormonas (Hormones, Your Friends), a health podcast hosted by Isabel Viña, where nephrologist José Luis Górriz joined to discuss the risks of overhydration.

The Bruce Lee connection

During the conversation, Górriz raised a startling example: “Why did Bruce Lee die?” he asked. Viña, visibly surprised, recalled a clinical session she attended years ago. “He died from hyponatremia,” she said.

Hyponatremia occurs when sodium levels in the blood drop dangerously low, often due to excessive water intake. Górriz explained that medical researchers had analyzed Lee’s case and concluded that his seizures and death were linked to drinking too much water.

What happens to your body when you overhydrate

The nephrologist broke down the science: When we’re dehydrated—say, after diarrhea or in desert conditions—the body concentrates urine to conserve water. But when we drink excessively, the kidneys can only excrete a limited amount of water.

Once that threshold is exceeded, sodium becomes diluted, leading to hyponatremia. This imbalance can trigger confusion, seizures, and in extreme cases, death.

Viral debate: how much water is too much?

The podcast clip quickly went viral, racking up more than half a million views, 8,000 likes, and hundreds of comments. Many viewers expressed confusion: how can doctors recommend drinking 2 to 3 liters of water a day, yet warn that too much water can be fatal?

Some of the most common reactions included: “So which is it? I drink more than 3 liters a day”; “I wasn’t crazy when I told my doctor I felt dizzy after forcing myself to drink water”; “Is the recommendation to drink 3 liters good or bad?”

While hydration is essential, experts stress that balance is key. Most healthy adults can safely follow the general guideline of about 8 cups (roughly 2 liters) of water per day, adjusting for activity level, climate, and individual needs. But forcing down excessive amounts—especially in a short period—can overwhelm the body’s natural regulation systems.
