Freezing at my job

I recently got a new job.  It is very similar to my last job but pays more money and works with a different demographic of the general population.  Leaving my former employer was hard, but it was time for a change.  I was nervous, but very excited to start the job.  But when I arrived on my first day, I felt so cold in the new office.  Initially, I thought it was just my nerves and hoped it would pass.  But as the day went on, I kept growing colder.  My hands felt like blocks of ice.  I did not want to express my concerns to my new coworkers and come across as needy or high maintenance.  I also did not bring my space heater that I had at my previous job, I figured I would bring my personal items from home after I got settled in.  What a huge mistake that was.  At one point, I walked past the thermostat and found it to be set at only 65 degrees!  My former employer kept it at 68 to 70 degrees in the middle of winter.  Now, I was not sure if this was going to be a good fit.  But I had to give it more than just one day to make a final decision.  Maybe my small space heater will produce enough heat to keep me warm enough.  I could also dress warmer and bring extra sweaters to wear in the event that I am too chilly in the office.  Perhaps this won’t be so bad after all.
