I have a variety of solutions, depending on the cause. Sinus headaches, I breathe steam. Towel over the head and the steam to keep it close to you.
I get headaches when I don't get enough sleep. Take a nap.
Tension headache, pressure points at the base of the skull, Massage the neck, put pressure in the two indents at the base of the skull and hold. You will get light-headed and that is how you know you got the right spots. Let go the pressure when the headache starts to fade, it will continue to fade.
Keep hydrated and get enough sleep because these will cause headaches
