My father was working on a treadmill in my diningroom. He couldn't see with the lighting available so he drags out a halogen floodlight to light up the room.
I was curious and decided to go in there to watch him work.
In less than 3 minutes I started feeling odd.
I couldn't think. Was weaken. Pain started shooting through my body.
I had to go sit down in another room. After resting for a few minutes I felt okay again. I walked back into the room where he was and felt a wave of weakness hit me.
I left and sat down again in different room and felt a little better. Went in again...weakness.
Bingo! Something told me to check halogens with UV radiation.
I found out Halogen lights emit a high UV radiation!
I'm now in a different room away from the light and will stay away until he is done.
