SUN gave me: -fevers -racing heart -PEM -pain -clogged ears & more. -Summer SAD I thought I got radiation sickness every time I went in it! This is when I lived in FL. I had to be a hermit then- for over 10 years. The fevers were awful. Would sleep for days. Like being poisoned exactly! Had to block windows, tint car. Thought when I left FL would be cured - I had no idea the winters up here can be worse! Sun not as bad in NJ. Angle/latitude and atmospheric condions have big impact. Still get summer SAD but not as long. Up here get winter SAD worse.
