The Science of Detox, Cold Exposure & Nervous System Healing | Alanna Kit

The Health Review

Show Notes

We’re living in a world our bodies were never designed for — microplastics, environmental chemicals, chronic stress, and constant stimulation. So what does detox really mean in 2026?

In this fascinating and forward-looking conversation, I’m joined by Alanna Kit — co-founder of Arc Community and a PhD researcher in behavioural and cognitive neuroscience — who is working at the cutting edge of integrative health, nervous system regulation, and psychedelic research.

We explore detox beyond diets and supplements, the role of inflammation and stress in modern illness, and why small, intentional stressors may actually make us more resilient.

Alanna also shares insights into her upcoming clinical research with UCL examining brain activity during cold exposure using EEG technology — and discusses whether cold plunging is truly harmful for women’s hormones, or if the reality is more nuanced.

We discuss:

What “detox” really means in modern life

Microplastics, chemicals & invisible stressors affecting health

Cold exposure, sauna & the science of hormesis

Whether cold plunging impacts women’s hormones

Why sauna after cold exposure may support recovery

Stress as a tool for resilience rather than something to avoid

The nervous system’s role in healing & inflammation

Psilocybin research and its potential impact on mental health & chronic inflammation

How inflammation may affect the blood-brain barrier

Why community is essential for healing in a post-pandemic world

The rapid growth of Arc Community and its vision for integrative wellness

This episode offers a science-led look at how we build resilience, support detox pathways, and rethink healing in the modern world.
