thread parallel to other process java

i have periodic thread that runs every one second and refers the application. the problem is when the thread is running cpu usage goes up and program respond very bad it seems CPU fan is working with full power. maybe there is a problem with using a infinite while here. is there any other way for doing it?

  Runnable r1 = new Runnable() {
            public void run() {
              try {
                while (connect.isDisable()){
                  refresher(rx);
                  Thread.sleep(1000L);
                }
              } catch (InterruptedException iex) {}
            }
          };
       Thread thr1 = new Thread(r1);
       thr1.start();

if there an alternate way that thhis sets of functions run every one secounds parallel to other process and event handlers respond just like normal?

To begin with, thread is a sequence of execution of statements or code in a program and is nothing hardware. It is a flow of execution which takes place.

A thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system.

And yes, multiple threads may run at the same time if your CPU has more than one core. This will of course increase the CPU usage because multiple processes or sequence of codes are running at the same time. You are asking the CPU to perform 2 or more things at the same time and therefore, over usage is an obvious consequence.

About the fan, may be designed to run faster when CPU usage is higher so that the excess heat generated is driven out efficiently.
