Headache is a major health problem that bothers most people today, regardless of age, on a daily basis. Many people tend to go to medical stores and buy painkillers as soon as they feel it. But a headache is not a disease, but a symptom of some other discomfort in the body. Pain is caused by the tension in the blood vessels, muscles, and nerves around the brain. Here are the 5 main scientific reasons behind headaches:
Tension Headache: This is one of the most common in the world. When there is severe mental stress, lack of sleep, and anxiety, the muscles in our head and neck tighten severely. Its main symptom is a heaviness and pain like a band being tightened around the head.
Sinusitis and Sinus Headache: There are some air-filled cavities inside the bones of our face. These are called sinuses. When these cavities become infected due to a cold or allergy, mucus builds up in them, causing swelling. This is the reason why there is a severe heaviness and stabbing pain in the forehead, under the eyebrows, and cheekbones when bending over.
Migraine: This is a very severe headache caused by chemical changes in the brain and overstimulation of the nerves. It is a shooting and throbbing pain that usually starts on one side of the head and then spreads to the eyes. The scientific symptoms of migraine include increased pain when exposed to light and sound, nausea, and vomiting.
Eye Strain: People with refractive errors (myopia/hyperopia) who cannot see letters clearly experience excessive strain on the eye muscles when they do not wear glasses. Along with this, those who stare at mobile and computer screens for hours on end also experience severe forehead pain and headaches by evening due to the strain.
Dehydration & Gastric Issues: When you don’t drink enough water every day, the water content in the brain cells decreases and the blood vessels temporarily constrict. This is a dehydration headache. Also, when you don’t eat on time, the stomach fills up with excess acid (Acid Reflux) and blood glucose drops. Headaches can also occur.
