A timer function to delay something

Hi

I am trying to add a delay to my respawn. The respawn at the moment simply relocates the player to x position and resets there health. All I want to do is delay the respawn so it doesn't happen instantly and can give the player a slight breather before the action kicks off again.

Any help is greatly appreciated, and heres some code if it helps.

     if (playerHealth <=0)
         {
             killPlayer();

             playerLives -=1;
         }

 void killPlayer()
 {
     //add delay here before doing the rest of the script
     player.transform.position = new Vector3 (-3, -3, -1);
             
     playerHealth +=100;
     
     if (playerLives <=0)
         {
             Application.LoadLevel (1);
         
             playerLives +=3;
         }
 }
