Professor Millian Andelman of the University of Pittsburgh's Department of Water Chemistry discovered through long-term research that toxic chemicals in the abundant steam generated during showers are easily absorbed by the human body. This can cause dizziness, blurred vision, chest tightness, rapid heartbeat, and elevated blood pressure—a condition known in the medical field as "Hot Bath Poisoning Syndrome."The professor emphasized that the severity of symptoms correlates directly with bathing duration, water temperature, and water volume used.
This conclusion was corroborated and expanded upon by a specialized research team. Their repeated experiments demonstrated that during showering, 50% of chloroform and 80% of vinyl chloride transform into vapor, whereas during baths, the volatilization of these toxic substances is only half that of showering.
Consequently, they concluded: 1. Showers are less preferable than baths; 2. Minimize bathing time and promptly ventilate by opening windows and doors afterward to disperse harmful vapors;3. Avoid using shower curtains during bathing; 4. Use the lowest water temperature possible while ensuring comfort; 5. Use cold or lukewarm water for washing to minimize inhalation of harmful substances mixed in water vapor, which can harm human health.
