New parents who clean their homes very often to protect their babies from bacteria and other organisms might want to cut back their efforts.
A new study suggests that high levels of contact with cleaning products are linked to an increased risk of the childhood breathing condition known as asthma.
Researchers asked a group of parents how often they used 26 common household cleaners during their babies' first three to four months of life.
By age three, the children who had come in contact with cleaning products the most were more likely to be diagnosed with asthma.
The researchers said that children who had a lot of contact with cleaners were 37 percent more likely to have asthma than children with the least contact.
The study also found that a lot of exposure to cleaning products caused children to be 35 percent more likely to have chronic difficulty breathing.
In addition, they were 49 percent more likely to have chronic allergies.
Tim Takaro, who helped lead the study, is a doctor with Simon Fraser University in Vancouver, Canada.
初为父母者会经常打扫房屋,以保护孩子免受可能想破坏他们努力的细菌和其他有机体的侵害。
一项新研究表明,大量接触清洁用品会增加儿童呼吸疾病――哮喘――的风险。
研究人员询问了一些家长在孩子出生后的三到四个月里使用26种常见家用清洁剂的频率。
接触过清洁用品的儿童,到三岁时更可能患上哮喘。
研究人员表示,就患哮喘的可能性来说,多次接触清洁剂的儿童比接触最少的儿童高出37%。
这项研究还发现,大量接触清洁用品会使儿童患上慢性呼吸困难的可能性增加35%。
此外,儿童患上慢性过敏的可能性也增加了49%。
蒂姆・塔加罗协助领导这项研究,他是加拿大温哥华西蒙弗雷泽大学的博士。
