While the cause of SIDS is unknown, many clinicians and researchers believe that SIDS is associated with problems in the ability of the baby to arouse from sleep, to detect low levels of oxygen, or a buildup of carbon dioxide in the blood. When babies sleep face down, they may re-breathe exhaled carbon dioxide.
SIDS usually occurs when a baby is asleep, although it can occasionally happen while they're awake. Parents can reduce the risk of SIDS by not smoking while pregnant or after the baby is born, and always placing the baby on their back when they sleep.
Frequent night waking is thought to be protective against SIDS. Studies of near-miss infants and siblings of SIDS infants show that these babies have fewer night-waking episodes.
Most SIDS deaths happen in babies between 1 and 4 months old, and cases rise during cold weather. Babies might have a higher risk of SIDS if: their mother smoked, drank, or used drugs during pregnancy and after birth.
White noise reduces the risk of SIDS.
A relatively famous study (famous if you read a lot about baby sleep, so honestly you should be a little proud if you haven't heard of it) showed that babies had a significant reduction in the risk of SIDS if they had a fan in their room.
Oftentimes, babies who succumb to SIDS have had a “minor infection” in the days before death. Infants' immune systems are immature, and breast milk helps to provide necessary antibodies to fight infections such as RSV, which can contribute to inflammation and lead to SIDS. Breastfeeding promotes safer sleep.
SIDS is most common at 2-4 months of age when the cardiorespiratory system of all infants is in rapid transition and therefore unstable. So, all infants in this age range are at risk for dysfunction of neurological control of breathing.
SIDS and SUDI are rare and the risk of your baby dying from it is very low. The rate of SIDS deaths has declined in Australia due to safe sleeping campaigns. In 2017, 6 babies in every 100,000 died of SIDS. Most deaths happen during the first 3 months of a baby's life.
It may be because babies don't sleep as deeply when they have a pacifier, which helps wake them up if they're having trouble breathing. A pacifier also keeps the tongue forward in the mouth, so it can't block the airway.
SIDS is not the same as suffocation and is not caused by suffocation. SIDS is not caused by vaccines, immunizations, or shots.
Overheating may increase the risk of sudden infant death syndrome (SIDS) in babies one month to one year of age. Many experts recommend that the temperature in the room where a baby's sleeps be kept between 68–72°F (20–22.2°C).
As indicated above, prone swaddled infants are at greatly increased risk for SIDS 8.
SIDS can occur anytime during a baby's first year of life (it's extremely rare after 1 year of age). Although the causes of SIDS are still largely unknown, doctors do know that the risk of SIDS appears to peak between 2 and 4 months of age and decreases after 6 months.
Babies who share a bed with other children or adults. Mothers who smoke during pregnancy (three times more likely to have a baby die of SIDS) Exposure to passive smoke from smoking by mothers, fathers, and others in the household (doubles a baby's risk of SIDS)
SIDS has no symptoms or warning signs. Babies who die of SIDS seem healthy before being put to bed. They show no signs of struggle and are often found in the same position as when they were placed in the bed.
Babies should be placed skin-to-skin on their mother's chest right after birth for at least the first hour. Babies benefit from skin-to-skin contact when breastfeeding as well as when being bottle fed. Sharing a bed with your baby puts them at a higher risk of SIDS, suffocation, or strangulation.
Deaths could occur more commonly at night in older infants because sleep is increasingly concentrated into the night. Prone sleep position could work through a thermal mechanism, so that the variables related to bedding and environmental temperature would be more important at night.
The Moro reflex is the cause of your newborn baby to sleep with his arms above his head. This reflex, commonly referred to as the “startle reflex”, disappears by 6 months of age. It occurs when light or noise startles your baby, even if the noise is not enough to fully wake the baby.
The potential factors that contribute to the occurrence of SIDS include inadequate prenatal care, low birth weight (<2499gr), premature infants, intrauterine growth delay, short interval between pregnancies and maternal substance use (tobacco, alcohol, opiates).
Babies that are too cold will not exert the energy it takes to cry, and may be uninterested in feeding. Their energy is being consumed by trying to stay warm. A baby that is dangerously chilled will have cold hands and feet and even baby's chest will be cold under his or her clothes.
Studies have found that bedroom heating increases SIDS risk,10 whereas well-ventilated bedrooms and use of a fan is associated with decreased risk of SIDS. These findings suggest that indoor heat is an important risk factor for SIDS.
Infants are sensitive to extremes in temperature and cannot regulate their body temperatures well. Studies have shown that multiple layers or heavy clothing, heavy blankets, and warm room temperatures increase SIDS risk.
The results found that running a fan in a sleeping infant's room lowered the risk for SIDS by 72 percent. That risk was lowered even further when the infant's sleeping conditions put him or her at higher risk for SIDS, such as sleeping in a warm room or sleeping on the stomach.
