Why can you feel the heat from ir radiation but not from radiation of higher or lower frequencies?

You can, if it's intense enough. A red laser pointer will not feel warm but a much more powerful laser of the same colour will.

Infrared is associated with heat because things that are warm or hot-but-not-super-hot emit most strongly in the infrared.
