There are a few reasons why a phone would run hot.
the first that comes to mind is your battery is bad. Overheating batteries can be an issue and safety concern.
As a safety concern I would recommend NOT using your phone.
A phone can get hot also if you push it past design limits. I was once streaming to my Chromecast from my phone and thought it was pretty neat. But I then notice my phone was getting very warm from trying to push the graphics that way.
If it is an iPhone 6s + I think your best option would be to get a new phone.
Or take in in and get a new battery. Geek Squad should be able to help you out if you bring it in.

If you have had it less than a month I would suggest contacting Apple Warenty support.
