5. Constrictive items
A necktie or a scarf is all you need. You can use a bandanna instead. Wear something constrictive around your forehead. Make sure that the tie is tight enough. This tip works because the scarf around your head will decrease the blood flow to your head. Soak the thing you use in vinegar for a better effect.

6. The importance of prevention
There are a few bad habits that may cause headaches. For instance, people clench their jaw or grind their teeth by day when they are awake or at night in bed. Control that habit and wear a mouth guard when you go to sleep. Do not go without food for long since hunger can also cause headaches.
