The smell of new slippers is not necessarily toxic, but it does not rule out that there may be harmful substances. Normally, the smell of new slippers is caused by the glue, dyes, chemical additives and other substances used in the production process. These substances may cause certain irritation and adverse effects on human body, such as headache, eye pain, cough, etc. However, the content of these substances is usually very small and will not cause serious harm to the human body.
If the smell of new slippers is too pungent or lasts for a long time, it is recommended to stop using them as soon as possible and put them in a well ventilated place for air circulation to reduce the volatilization of harmful substances. In case of physical discomfort, seek medical advice in time. At the same time, when purchasing new slippers, you should choose the products produced by regular manufacturers, and pay attention to the material and composition of the products to reduce the risk of harmful substances.
