How Hormones Affect Sleep in Babies and Parents
So, you have heard sleep consultants banging on about overtiredness and cortisol levels.... And you may get it but may wonder why? Below you can find out why thinking about hormone levels and how it impacts sleep is important to understand.
How Hormones Affect Sleep in Babies and Parents
Sleep is a vital component of health for both babies and parents. Hormones, particularly cortisol, play a significant role in regulating sleep patterns. Understanding how these hormones function can help families achieve better rest.
Understanding Sleep Cycles in Infants
Infants have shorter sleep cycles compared to adults, typically lasting about 40-45 minutes. These cycles include both active (REM) and quiet (non-REM) sleep. As babies grow, their sleep cycles lengthen, and they begin to develop more predictable sleep patterns.
The Role of Cortisol in Sleep
Cortisol, often referred to as the "stress hormone," follows a diurnal rhythm, peaking in the early morning and declining throughout the day. In infants, this rhythm is not fully developed at birth but begins to establish around 2 months of age and becomes more consistent by 8 months. (as shown in a study at Boston University)
Elevated cortisol levels in infants have been associated with fragmented sleep and increased night awakenings. Factors such as stress, overstimulation, and irregular sleep routines can contribute to higher cortisol levels, disrupting sleep patterns.
Cortisol Spikes: Infants vs. Adults
While both infants and adults experience cortisol fluctuations, the impact on sleep can differ. In adults, stress-induced cortisol spikes may lead to difficulty falling asleep or staying asleep. In infants, elevated cortisol levels can result from factors like overtiredness, inconsistent routines, or environmental stressors, leading to frequent night waking's and early morning awakenings. making it difficult to tell if your little one is over or under tired.
Strategies for Managing Cortisol Levels and Improving Sleep
Establish a Consistent Routine: Regular sleep and wake times help regulate cortisol rhythms.
Create a Calming Environment: A quiet, dark, and comfortable sleep setting can reduce stress and promote better sleep.
Respond to Sleep Cues: Recognize signs of tiredness and put your baby to sleep before overtiredness sets in.
Limit Stimulants Before Bedtime: Reduce exposure to screens and stimulating activities in the evening.
Practice Gentle Soothing Techniques: Comforting your baby with gentle methods can help lower cortisol levels and ease the transition to sleep.
