Vigilant researchers have investigated whether microbes in showerheads might be dangerous to human health. Ribosomal RNA sequences from the interior surfaces of 45 showerheads across the US were analyzed. Fortunately, the bacteria identifed were mostly the common soil and water microbes, and rarely cause human infection. The bacteria that commonly cause skin infections such as Staphylococcus. aureus and Streptococus pyogenes were not found. For those who have compromised immune systems there may be a slight risk of infection from aerosolized shower water. The researches suggest that for nearly all healthy people, showers are very safe.
PositiveTip: Choose your motel wisely, but don’t let fear of microbes cause you to avoid showers.
