Patients with headaches throughout the day are considered to have neurovascular headaches. There are many causes of neurovascular headache, such as excessive mental tension or psychological stress, overexertion, including excessive physical activity, insomnia and excessive dreaming, which cause the brain to be insufficiently rested and the headache to appear. Some patients may suffer from headaches due to frequent consumption of spicy and irritating foods that cause the body to become inflamed. Some patients may also have headaches due to drinking stimulating beverages such as strong tea, coffee and Red Bull. If you have headache for a whole day, we suggest you to compare the above triggering factors to see which one you belong to.
