Sudden infant death syndrome (SIDS) is the unexplained death of an infant under one year of age. While the exact cause of SIDS is still unknown, there are certain risk factors associated with it.
Babies between the ages of 1 and 4 months are at the highest risk for SIDS. Other risk factors include: pre-term birth, having a low birth weight, being male, sleeping on their stomach, being exposed to secondhand smoke, being exposed to over-heating, and having a mother who smoked during pregnancy.
Babies who are put to sleep on their stomachs are at the highest risk for SIDS. This is because when a baby is sleeping on their stomach, they are more likely to suffocate due to their face being pressed against the mattress or other objects in the crib.
Premature and low-birth weight babies are also at an increased risk for SIDS. This is due to their immature lungs and nervous system which makes it more difficult for them to regulate their breathing.
Being a male increases a baby's risk of SIDS as well. Studies have shown that male infants are twice as likely to die from SIDS than female infants.
Exposure to secondhand smoke has been found to be a risk factor for SIDS as well. Tobacco smoke contains several toxins which can irritate a baby's airways and make it difficult for them to breathe.
Exposure to over-heating can also increase the risk of SIDS. When a baby is too warm, it can cause them to become inactive and have difficulty breathing. It is important to keep a baby's environment at a comfortable temperature.
Finally, mothers who smoked during pregnancy are more likely to have a baby who is at risk for SIDS. Cigarette smoke contains toxins which can be passed on to the baby in utero and increase their risk of SIDS.
In conclusion, babies between 1 and 4 months old, those who sleep on their stomachs, those who are pre-term or have a low birth weight, those who are male, those exposed to secondhand smoke, those exposed to over-heating, and those whose mother smoked during pregnancy are all at an increased risk for SIDS.
