Chronic headaches in the morning can be brought on by a number of causes, the most common of which includes teeth grinding. In addition, research has found that morning headaches may be brought on by certain medications and sinus congestion. Women are more likely than men to develop headaches in the morning. Often, a variety of treatment methods will be attempted to eradicate symptoms.

Nighttime teeth grinding has been found to be a common cause of headaches in the morning. Those who grind their teeth during the night are often recommended to wear mouth guards. Wearing this protective gear can not only aid in preventing chronic morning headaches, but can also reduce dental damage. While some dental mouth guards can be purchased over the counter, studies have found that those that a dentist designs for a specific patient provide the best results. In most cases, insurance will cover the costs associated with these items.

Certain medications can be the cause of headaches in the morning. Those who have been taking opiates, certain painkillers, or even caffeine for an extended period of time are likely to experience morning headaches, though other medications may also lead to pain. Individuals whose morning headaches increase after starting a new medication are often encouraged to switch to a different product. A doctor or pharmacist will likely be able to suggest a medication that offers the same benefits without similar side effects.

Sinus congestion is a common cause of morning headaches. Often, those who suffer from chronic sinus congestion will need to undergo invasive forms of treatment in order to completely eradicate headaches in the morning. In most cases, headaches will decrease significantly in both severity and frequency once the sinuses have been cleared.

Some studies have found that women are more likely to develop headaches in the morning than men. This may be due to changes in hormone levels between men and women. Sometimes, women are administered male hormones to treat the condition. This treatment is not typically considered ideal for long-term use, however, and should be used with caution.

Dehydration is another common cause of headaches in the morning. Those who believe that their morning headaches may be caused by dehydration are typically encouraged to consume plenty of liquids over the course of the day. In most cases, chronic dehydration is caused by high amounts of physical activity or the use of certain medications. In addition, avoiding alcohol, soda, and other beverages known to have diuretic properties can also greatly reduce the chances of developing dehydration.
