Health experts advise that reusable water bottles should be washed daily, particularly those with straws or mouthpieces, to prevent bacteria accumulation. Biologists highlight that moist environments in these bottles can foster dangerous microorganisms, especially when exposed to external contaminants like soil bacteria from public places. Pediatrician Dr. Amy Cobb further emphasizes that oral bacteria can transfer from users to the bottle, increasing health risks. Parents are also encouraged to regularly clean baby bottles and cups. To maintain hygiene, experts recommend using soap and water, focusing on hard-to-clean areas, and ensuring bottles are completely dried before reuse.
