Today I went in a stand up tanning bed. I have tanned numerous times but always in the beds where you lie down. Today before I even got in the stand up bed I noticed the room was very hott. It was set to 12 minutes. At about nine minutes, I started to get anxious and at about ten minutes through I couldn't take it and got out. When I got out I knew I was light headed. I felt my face go pale and was very dizzy. I had to sit down before he getting dressed. I tried really hard to get dressed but I was just too light headed and dizzy and I felt very weak. The next thing I know is I am on the floor and I hit my head hard. I don't even remember falling down. I immediately got up and tried to push through it and put my clothes back on. When I got outside my friend said I was so pale and gave me water. After about ten minutes I felt better for the most part. My head still hurts from my fall and I have a scrape on my shoulder. What could this possibly be??
