Hi, I'm Dr Oscar Serrallach
Maternal health specialist, with a focus on integrative and functional medicine, and postnatal wellbeing.
We're often told to “relax”…Â
But it's not often explained how your body actually returns to a state of calm.
Modern life keeps many of us stuck in a low-level stress response — wired, tired, and unable to fully switch off.
In all my years of clinical experience supporting depleted mothers to regain wellbeing, few practices have proven as effective as Yoga Nidra in helping both establish and sustain the body’s relaxation response.
This short masterclass bridges the gap between ancient practice and modern science — helping you understand:
- Why stress gets “stuck” in the body
- What’s happening in your brain when you can’t switch off
- And how Yoga Nidra works at a physiological level to restore balance
When stress becomes chronic, the body loses its ability to return to baseline. You don’t just feel stressed — you live there.
Yoga Nidra offers a direct pathway back to balance by interrupting the stress cycle, re-engaging the body’s natural relaxation response, and supporting both brain and nervous system recovery.
In this masterclass, you'll learn:
- The true nature of Yoga Nidra and the state of “dynamic sleep”
- How chronic stress affects your brain and body
- The nervous system pathways that drive stress and recovery
- How Yoga Nidra changes brain activity and builds resilience
- The measurable benefits for sleep, anxiety, hormones, and health
This masterclass is grounded in neuroscience and brain imaging research, polyvagal theory and autonomic nervous system science, and clinical studies on sleep, stress, mood, and inflammation.
Suitable for you if you:
- Want a science-backed understanding of Yoga Nidra
- Are a health professional, or you already offer/receive Yoga Nidra — or have been thinking about it
- Are interested in nervous system regulation and mental wellbeing
- Want practical tools grounded in both tradition and research
