In one of our recent blogs, we started talking about the rates of depression in pregnancy and post-natal depression including some of the implications of depression during and after pregnancy. Some of these risks included pre-term delivery, preeclampsia (high blood pressure), and birth difficulties. (1)
Following on from this, a recent study conducted in Victoria looked to see if it were possible to predict sleep problems for infants in the first year of life. They concluded that poorer prepartum and postpartum maternal mental and physical health; including poorer physical function, increased emotional problems, and decreased energy and vitality; were associated with reports of persistent severe infant sleep problems. (2)
Furthermore, maternal depression and anxiety has been associated with poorer right white frontal microstructure in 1-month old infants. This area of the brain is important for self-regulation needed for sleep. (2)
Cook et al. states: “Maternal prenatal stress alters melatonin levels, reducing generation of the circadian rhythm in the foetal adrenal gland, which is vital for the development of infant sleep, and potentially limiting foetal growth. Maternal prenatal depression raises free cortisol levels which in turn increases infant cortisol levels. Higher infant cortisol can result in poorer infant sleep quality and more frequent waking.” (2)
This does become a vicious cycle, as your child sleeps less, so do you. Lack of sleep can increase fatigue, depression and anxiety, which promotes the poorer sleep patterns in infants! So, for expecting mums, planning mums, and new mums; getting on top of your health will make a difference on the outcomes not just for you, but also for your infant and his or her sleep.
