Tobacco smoke contains a variety of harmful chemicals that can affect the respiratory system and increase the risk of SIDS.
Infants who are exposed to tobacco smoke, either before or after birth, are at increased risk of SIDS compared to infants who are not exposed to tobacco smoke.
The risk of SIDS is higher for infants whose mothers smoke during pregnancy, as well as for infants who are exposed to secondhand smoke after birth.
Infants who are exposed to tobacco smoke may have a harder time arousing from sleep or may have a decreased ability to respond to challenges to their breathing, such as changes in position or exposure to smoke.
In addition, tobacco smoke exposure may affect the development and function of the brain and respiratory system, making the infant more vulnerable to SIDS.
To reduce the risk of SIDS, it is important to avoid exposing infants to tobacco smoke, both before and after birth. This includes avoiding smoking during pregnancy and ensuring that the infant's sleep environment is smoke-free.
It is also important to use a firm, flat surface for sleep, such as a crib or bassinet, and to place the infant on their back to sleep.
In addition to tobacco smoke exposure, it is important to be aware of other risk factors for SIDS, such as placing the infant on their stomach to sleep and using soft bedding.
By taking steps to reduce the risk of SIDS, parents can help protect the health and well-being of their infant.
