Generally speaking, it's not a great idea. Any code you #include is going to have to be compiled, whether or not you used it. So you'd be taking more time and space to build things that you wouldn't be using.
That should only increase the program size but on runtime it shouldn't be much bad, if you think that your program will have a future development using those headers, there is nothing wrong in including them. Of course if you include them just because you like typing, is not that useful...
Note that it only hurts compile time. Run time is unaffected by inclusions. Not even code size is affected by inclusions. In most cases. MinGW is an exception: including a certain part of the standard library increases code size tenfold.
