I work in Tokyo where they keep the office on about 26C (78.8F), which is normal according to Japanese standards. I come from Louisiana where we keep our house on 68F (20C). Wearing long pants is not a rule but everybody here does it. There's about 100 employees on my floor and I'm the only one who ever seems to be burning up.
What can I do about this? Even if I wear shorts my back and legs get damp. And my chair is already a mesh like chair with holes all through out it to allow airflow.
