A scientific way to treat Headaches without painkillers

Rest and Relaxation: Often headaches can be relieved just by getting enough rest and relaxation. Lie down in a dark, quiet room and do deep breathing exercises to relax.
Hydration: dehydration is a common cause of headaches. Drinking plenty of water can help relieve or prevent headaches.
Caffeine: In some cases, a small amount of caffeine can provide relief. This can be from coffee, tea, or a drink containing caffeine.
Over-the-counter pain relievers (OTC): Non-prescription pain relievers such as ibuprofen (Advil), acetaminophen (Tylenol), or aspirin can be effective for many types of headaches. Follow dosing instructions carefully.
Cold compress: Applying a cold compress to the forehead can help relieve a headache, especially if it's a tension or migraine headache.
Heat Therapy: For tension headaches, applying heat to the neck and shoulders can help loosen tight muscles.
