This is a strange question but I wondered if anyone else had been to the archeological museum and had ended up feeling sick.
My partner and I went there last week and after being inside for about 15 minutes I started feeling dizzy and like the floor was giving way when I was walking. I didn't say anything as I thought I just must have been tired but then my partner said that he was feeling sick as well. Walking around we noticed other people looking poorly and taking every opportunity to sit down.
We thought perhaps that the museum puts air with a high level of oxygen through their aircon to preserve the statues or something, we actually had to leave because we felt so bad.
