Is Sleep Deprivation Making You More Sensitive?


It’s common knowledge that sleep deprivation is part of the new parent package. Everyone teases new parents about the myth that they'll never sleep again. Many people have come to accept feeling tired day after day as just one of the burdens of parenthood, but did you know that lack of sleep can impact your cognitive functions, including emotional processing and perception? Today, we will delve into some of the scientific findings that underline the importance of adequate sleep and how it can transform your parenting experience.


Research has established a link between sleep deprivation and emotional processing, particularly the way we perceive and respond to negative emotional stimuli. While no studies specifically focus on the effects of sleep deprivation on parents’ reactions to a child’s cries, extrapolating from current research offers some interesting insights.


In 2007, a study conducted by Yoo et al. revealed that sleep deprivation results in the amygdala—the area of the brain involved in processing emotions—reacting more to negative emotional stimuli. What does this mean for you as a new parent? With the sleep deprivation that often accompanies this phase of life, your emotional responses could be heightened, potentially causing you to perceive your baby’s cries as more distressing than they might be under-rested conditions.


Further emphasizing the effect of sleep deprivation on emotional regulation, a study by van der Helm et al. in 2010 showed that sleep deprivation could impair emotional regulation by disrupting the connectivity between the amygdala and the prefrontal cortex. The prefrontal cortex plays an essential role in controlling emotional responses, implying that sleep deprivation might exacerbate negative or distressing perceptions, such as the sound of your baby crying.


These studies suggest that sleep deprivation might lead to amplified emotional reactivity and altered perception of emotionally taxing stimuli. In a nutshell, you just may be overreacting.


This is where my role as a Sleep Sense Consultant comes into play. I am here to help ensure that your family transitions smoothly into this new phase of life, with everyone achieving healthier, more restful sleep. By implementing tailored, gentle strategies, we can work together to help your baby (and you!) get the sleep needed to thrive.


But why does this matter? A well-rested parent is more likely to have balanced emotional reactions, making it easier to respond to your child's needs effectively. Adequate sleep not only aids in maintaining emotional balance, but it also helps to improve overall mental and physical health. The result? A more serene and enjoyable parenting experience.


Sleep deprivation is not an inevitable part of parenthood. With the right guidance and a little patience, you can enjoy these precious early days with your newborn without the burden of chronic fatigue. As a Sleep Consultant, my mission is to support you in this journey, using evidence-based techniques to promote healthy sleep habits for your whole family.
