I have to reset switch in basement if I don't turn off space heater when I use the blow dryer
A cellphone charger is an inconsequential load.  The lamp would also be inconsequential if you'd put LED bulbs in it.  The laptop certainly uses less than 10% of the circuit's capacity, maybe even 3-5%.  

A blow dryer is a huge load, and takes 80% of a circuit's capacity.  

A heater is also a huge load that takes 80% of a circuit's capacity.  

Those two devices take so much because their mission is to create heat.  They want to make as much heat as possible, so they use the circuit up to its limits. 

Most bedrooms have 1 circuit, so it's effectively all the same side. 

Now that you know, you could try living with it. 

Or you could use the blow dryer in the bathroom, which usually has a separate circuit for this reason.  

You could use the house's own heating system instead of using space heaters, gas is cheaper to heat with. 

You could install hardwired electric heaters on their own circuit, the heaters are cheap, the power to run them is expensive. 

Other than that, yeah, you'd have your electrician pull another bedroom circuit.  We cannot begin to speculate what that would cost, because it totally depends on the particular construction of your home.  It will be at least $100 and likely a whole lot more.  This varies too much to even guess at.



Details...  Household power in North America is 120 volts.  That switch downstairs (called a breaker) will have a number on it, probably 15, which the curcuit's capacity in amps.  Useful power is measured in watts, which is volts x amps.  15 amps x 120 volts  is 1800 watts.  Most devices will state their watts.  Some will state amps, and you must multiply by 120.  

Watts are often abbreviated W, or sometimes you see a similar unit called VA. 

Your cell phone charger is probably 7-10 watts -drop in the bucket. 

Your laptop is probably somewhere between 35W and 150W.  

Your lamp - anyone's guess. They made 500W halogens. LED bulbs are as little as 7W. 

Your hair dryer will say, but expect to see 1500W.  

Your heater, ditto.
