I really really doubt the office has the air conditioning on below freezing temperatures...

75-95 is Faranheight I assume, yes? Well, an average air-conditioned building is between 70-75 degrees Faranheight... Freezing on the faranheight scale is 32 degrees.

If that scale is Celcius... well 95 degrees celcius is just ridiculously hot, as in, 5 degrees below the boiling temperature of water O.o SO I doubt the Caribbean is that hot. I know it isn't. However, 15-20 degrees Celcius is pretty nice if not on the chilly side, as freezing on celcius is 0.

So.... which scale are you using? Do you have a sub-freezing office, or boiling air outside?

Sorry Eiri

The temperature in my island ranges from 75-95 degrees faranheight and because of the AC my office temperature ranges from 16-20 degrees celcius (60.8-68 degrees faranheight). And although that may seem pretty nice if not on the chilly side, you have to remember it is pretty hot where i come from and i have never experienced winter so i am not used to the cold.

I think you're probably fine. If you feel cold, you can always bring a sweater or a change of clothing to switch into when you're at work. Also, you can take vitamins like C and A. Those should help prevent colds.

I usually wear two sweaters and gloves when I am at work and so do the other staff members and we still feel extremely cold. But that is not really my concern. I want to know the possible health effects of going from extreme hot temperatures to extreme cold temperatures and vice versa several times a day.

i live in canada, (hello, cold!!) and in the winter we have the same issue of going from hot to cold a lot. in the winter it can be -40 C outside and 20-25 C inside. in the summer we have the same kind of heat. right now we are having a lot of hot weather so it has been up to 47 C with the humidex and most places are kept at about 20 C indoors. i've never noticed any health effect from it. if anything you may feel dizzy or faint maybe. i remember being in las vegas and the temperature differences between the indoors and outdoors was so huge it was making me feel nauseous. if you are really feeling the cold indoors maybe you could talk to someone about increasing the temps a bit. it sounds like you aren't the only one getting chilled. i remember my mom telling me a few times growing up not to get a chilled back in the winter when i had my period but i can't for the life of me remember if she told me why. of course there is a big difference between being chilled from -40 and being chilled from 20.
