How Light Therapy May Ease Seasonal Affective Disorder
We examine why shorter winter days can trigger seasonal affective disorder, how reduced sensitivity to blue light may play a role, and why 10,000 lux of morning light is often recommended. Dr. Chi-Ming Chow also covers cocaine becoming the leading substance linked to drug deaths in England and Wales, CVS Health’s planned split, and the promise and challenges of individualized mRNA vaccines for melanoma.
Key Points
- Seasonal affective disorder is strongly tied to reduced daylight, and morning bright-light therapy, regular sleep, time outdoors, and CBT can all help relieve winter depression symptoms.
- Drug poisoning deaths in England and Wales remain alarmingly high, with cocaine now surpassing heroin as the leading cause and synthetic opioids and ketamine adding to the crisis.
- New research suggests personalized mRNA cancer vaccines may improve melanoma outcomes when combined with pembrolizumab, while longer lifetime estrogen exposure may be linked to better brain health in older women.
