Cortisol & Sleep Training
If you've spent any time researching baby sleep, you've probably come across conversations about cortisol, often referred to as the "stress hormone".
For many parents, hearing that cortisol levels can temporarily rise when a baby cries can feel worrying. It's understandable to want reassurance that the choices you're making are supporting your child's wellbeing.
The good news is that current research tells us that temporary increases in cortisol during periods of stress are a normal part of human biology. In fact, cortisol plays an important role in regulating sleep, alertness, metabolism, and our body's response to challenges.
When it comes to sleep training, many of the concerns surrounding cortisol are not supported by the evidence.
As sleep specialists, our role is never to tell families what they should do. Instead, we believe in providing balanced, evidence-based information so you can make informed decisions that feel right for your family.
Because sleep is about so much more than getting through the night.
It's about supporting the wellbeing of the whole family, helping everyone wake feeling more rested, connected, and able to enjoy life together.
