Tanning bed problem

Hello, I have noticed that, everytime I go to tan in a tanning bed, I get sick the next day. I tried many tanning beds and lotions, but nothing helped. I need to go to tanning bed, it's a part of my job I can't use alternative ways to tan (however, I always use tanning bed rules), so I need to fix this problem. It only happens in winter, I don't get sick in the summer. Few times I was okey after tanning bed, when I immediately went to shower.
Symptoms:
Headache, blushing, feeling low energy, hotness. Some people say it might be tanning bed causing Reflux Desease.

Hope this information helps,
Thank you.
