Is it dangerous if headaches happen again and again at the same time?

Medical professionals call this type of headache a cluster headache, also known as a cluster headache. The headaches are usually severe on one side of the head or around the eye. The pain can occur cyclically, at the same time of day without warning, according to the health website Verywell Health (USA).

Headaches that repeat on the same day may be due to cluster headaches.

The pain is severe and is often described as a sharp, burning sensation, occurring around the eyes, temples, and sometimes in the face. If a person has a headache in one location, it will likely be in the same location in subsequent headaches.

The pain is intense and acute, occurring at least 1 to 7 times a day, mostly in the middle of the night. Anyone can get cluster headaches. However, the condition is more common in people in their 30s and 40s.

What is the cause?

Scientists have yet to discover the exact cause of cluster headaches. However, a study published in the journal Neurology found a strong link between circadian rhythms and cluster headaches.

The authors of the study said the cause may be related to cortisol and melatonin, two hormones that affect sleep in humans. They found that about 71% of people with cluster headaches had their headaches late at night or early in the morning, suggesting that cluster headaches are linked to the body's internal clock.

Early morning headaches are primarily caused by higher cortisol levels and lower melatonin levels, which disrupts sleep almost every day.

Cortisol is the hormone that helps you stay awake, while melatonin is the hormone that makes you sleepy. Because these two hormones have opposite effects, an imbalance can cause difficulty sleeping at night and drowsiness during the day. This can lead to difficulty concentrating, lack of alertness, and headaches during the day.

If you often have headaches at the same time of day, you need to adjust your circadian rhythm by going to bed on time, getting some morning sunlight, and reducing exposure to electronic screens such as phones, tablets, laptops, and televisions. In addition, avoiding caffeine before bed, arranging a quiet, dark, and comfortable bedroom temperature can also help improve headaches, according to Verywell Health .
