Stories about sailors who died or went mad from thirst in the middle of the ocean were read by everyone in childhood. How does this compare with the actual situation? Everyone knows that seawater is not suitable for drinking. But what about swallowing a small amount – for example, taking a few sips?
Myth and Truth
Myth: Seawater is sterile, and swallowing a small amount poses no health risk.
Truth: Seawater is not sterile. It contains numerous bacteria, viruses, and other microscopic organisms. Although in colder temperatures (below 24 degrees Celsius), these microbes do not multiply very actively, making their concentration relatively low and not particularly dangerous to health. However, in warmer waters, the risk increases significantly.
What is the reality of the situation? For commentary, we turned to Dr. Anthony Fauci, a well-known immunologist and former director of the National Institute of Allergy and Infectious Diseases. And here is his verdict: not deadly, but there is a risk.
“Seawater contains a diverse array of microorganisms, including bacteria and viruses. In colder temperatures, microbial activity is lower, but in warmer waters, the risk of infection increases. While swallowing a small amount of seawater is not likely to be deadly, it can still cause gastrointestinal issues such as diarrhea,” explains Dr. Fauci.
