If severe, water poisoning can trigger seizures. The swelling brain can disrupt electrical signals, causing your body to convulse uncontrollably. At this stage, it’s a medical emergency—call for help immediately. Coma and even death are possible if sodium levels drop below 120 mmol/L (normal is 135-145).
But let’s pump the brakes: you’d need to drink gallons in a short time to hit this point. For reference, an adult kidney can process about 0.8 to 1 liter of water per hour. Downing three to four liters in an hour? That’s flirting with danger.
Fun fact: the human body is about 60% water, but your brain is 73%. So when you overdrink, you’re literally drowning your most vital organ. Irony level: expert.
