New parents face six years of disrupted sleep, reveals study

Representational picture

Washington D.C: A child's birth has a drastic short-term effect on new mothers sleep, particularly during the first three months after birth. The research, conducted at the University of Warwick also found sleep duration and satisfaction is decreased up to six years after giving birth for both parents.

In the paper 'Long-term effects of pregnancy and childbirth on sleep satisfaction and duration of first-time and experienced mothers and fathers', a collaboration with the German Institute for Economic Research and the West Virginia University studied sleep in 4,659 parents who had a child between 2008 and 2015.

During these years parents also reported on their sleep in yearly interviews. In the first 3 months after birth mothers slept on average 1 hour less than before pregnancy while fathers sleep duration decreased by approximately 15 minutes.

According to study author Dr Sakari Lemola, "Women tend to experience more sleep disruption than men after the birth of a child reflecting that mothers are still more often in the role of the primary caregiver than fathers."

However, when the children were 4-6 years old sleep duration was still about 20 minutes shorter in mothers and 15 minutes shorter in fathers compared to their sleep duration before pregnancy. A similar time course was also observed for their satisfaction with sleep.

Sleep effects were more pronounced in first-time parents compared with experienced parents. In the first half a year after birth the sleep effects were also somewhat stronger in breastfeeding compared with bottle-feeding mothers.

Higher household income and psychosocial factors such as dual vs. single parenting did not appear to protect against these changes in sleep after childbirth.

Dr Sakari Lemola, added, â¿¿While having children is a major source of joy for most parents it is possible that increased demands and responsibilities associated with the role as a parent lead to shorter sleep and decreased sleep quality even up to 6 years after birth of the first child."
