Final Thoughts

Headaches and migraines have overlapping but distinct causes. Headache vs Migraine Causes include stress, dehydration, diet, hormonal changes, genetics, and environmental factors. Understanding triggers allows for prevention, lifestyle modification, and proper treatment. Migraines are neurological and often severe, while headaches are usually mild, tension-related, and lifestyle-linked. Identifying personal triggers is key to reducing severity and improving daily life.
