Why Does Human Saliva Prevent Goggles from Fogging?
Human saliva helps prevent goggles from fogging thanks to its natural surfactant agents, which reduce surface tension and stop mist from forming. Baby shampoo or anti-fog sprays can also be used as alternatives. These methods improve visibility and enhance the experience during activities such as swimming, diving, or skiing.

Fogging is a natural phenomenon that happens when water vapor condenses on a solid surface whose temperature falls below the dew point of the surrounding air-vapor mixture. Your goggles begin to fog up because your face (inside the goggles) is warmer than the outside environment—in this case, the water. Human saliva contains surfactant agents that break the surface tension, preventing condensation from forming into mist. You can also use baby shampoo or an anti-fog spray.
The fogging effect is a natural process that occurs under certain temperature and atmospheric conditions. It happens when the water vapor in the air condenses onto solid surfaces that are cooler than the dew point of the surrounding air.
With goggles, fogging is common because the skin on your face inside the goggles is typically warmer compared to the outside environment. This thermal difference promotes condensation of water vapor on the inside surface of the goggles, creating the bothersome mist that interferes with vision. However, there is an easy and accessible remedy: human saliva.
Saliva contains components that act as surfactants, which have the property of breaking water’s surface tension. This prevents water droplets from collecting on the inside surface of the goggles and creating condensation, thus avoiding fogging. This makes saliva an effective solution, especially in sports or diving situations where visibility is essential.
In addition to saliva, there are other alternatives to prevent goggles from fogging. Baby shampoo is a popular choice: apply a small amount to the inside of the goggles, spread it evenly, and rinse with water. There are also specialized products, such as commercial anti-fog sprays, specifically formulated to protect goggle and lens surfaces.
In summary: Fogging is a physical phenomenon caused by temperature differences between your skin and the environment. Human saliva, baby shampoo, and specialized anti-fog products can all be effective in preventing fogging, ensuring clear vision and comfort during sports or outdoor activities.
