One possible explanation for this link is that parental stress may disrupt the normal functioning of the stress response system, which can affect an infant's ability to regulate their heart rate and breathing during sleep.
In addition, high levels of stress may lead to poor sleep quality and sleep disturbances, which may increase the risk of SIDS.
It is important to note that the relationship between parental stress and SIDS is complex and not fully understood.
Further research is needed to better understand this relationship and to identify strategies for reducing the risk of SIDS in infants of stressed parents.
In the meantime, it is important for parents to take care of their own physical and mental health, as well as the health of their infant.
This may involve seeking support from friends, family, or healthcare professionals, and finding ways to manage stress and promote healthy sleep habits.
