Founder of wuusaa.com - an evidence-based resource for breathwork, sleep, and nervous-system regulation. I curate peer-reviewed research into practical techniques anyone can use, breaking down sleep science, vagal tone, and stress regulation for readers who want what works without the wellness hype. Background: years in sales, not a clinician - every article on wuusaa cites the original study so readers can verify the source themselves. Available for commentary on sleep onset, breathwork techniques (4-7-8, box breathing, cyclic sighing), nervous-system regulation, and consumer sleep products (sound machines, weighted blankets).
