HEADACHE hurt because pain-sensitive nerve endings in your scalp, blood vessels, and neck muscles send distress signals to your brain, even though the brain itself cannot feel pain.
It happens when pain-sensitive nerves in the muscles, blood vessels, and surrounding structures of your head and neck are activated.
Common Reasons of Headaches
- Tension: Increased sensitivity to pain or tight muscles around the neck and scalp.
- Blood vessel changes: Widening or shifting of blood vessels inside the head that press against nearby nerves.
- External factors: Dehydration, hunger, missing sleep, or sinus inflammation.
- Sinus or ear infections
- Cold or flu
- Head injuries
- High blood pressure
Common Daily Causes
- Stress and Anxiety: Emotional tension makes the muscles in your neck, shoulders, and scalp tight.
- Medication Overuse: Taking pain pills more than two days a week can cause your brain to trigger rebound headaches.
- Dehydration: Not drinking enough water throughout the day decreases blood flow to the brain.
- Poor Sleep: Irregular sleep schedules or bad sleep quality disrupt how your brain handles pain.
- Screen Time: Staring at phones or computers for long hours strains your eyes and neck.
