dr Marek Wójcik
Psychiatrist
Specialist physician in psychiatry, mental-health & sleep consultant
Marek specializes in psychiatry and spent most of his career at the intersection of psychiatry and sleep medicine, watching how often mood disorders and sleep problems feed each other — and how treating them separately tends to work worse than treating them together. Julia talked him into joining, having met him while both were working on the topic of insomnia: him from the clinical side, her from chronobiology. He reviews content on how supplements and lifestyle affect mood, stress and cognitive function, always underlining the difference between easing a symptom and treating its cause, and flagging when a topic goes beyond what's safe to handle on your own. He believes the biggest risk in popular mental-health content isn't too little information but too much of it with no sense of priority — and that's the hierarchy he tries to bring to his reviews.
Medically reviewed
4.5Cortisol
The main stress hormone — essential for short-term survival, but problematic when chronically elevated.
4.6Chronic Stress
Short-term stress is a natural, adaptive body response — the problem is when it becomes chronic. A large meta-analysis of data from nearly 200,000 people found a concrete number for how much chronic job stress raises coronary heart disease risk.
4.7Insomnia
Chronic difficulty falling or staying asleep isn't just a matter of 'sleep hygiene' — the best-studied intervention, recommended as first-line treatment, is cognitive behavioral therapy for insomnia (CBT-I), not sleeping pills.
