Il heachache shows up punctually every day at the same time. The causes exist. Indeed, it is not a coincidence. A study published in the journal explains it Neurology, pwhich analyzes the reasons related to this manifestation especially of cluster headache. Headaches almost always depend on circadian rhythms and an unbalanced biological clock.
Causes headaches at the same time
Cluster headache: what is it?
Cluster headache is a form of headache that manifests itself as a sharp pain in the temple, usually on only one side of the head, that radiates around the eye. Multiple attacks can occur throughout the day, usually occurring at the same time of day or night.
Migraine and circadian rhythms: the study
The study, conducted by researchers at the Health Science Center of the University of Texas at Houston, examined the response of cluster headache and migraine patients, and the daily occurrence of headaches. What did they highlight? That most of the subjects who participated in the study, the 71% with cluster headaches showed an intense level of pain in the evening, between 21:00 and 03:00While 50% of migraine sufferers experience the most pain between 11pm and 7am. Not only do these peaks occur at the same times every day, but they also tend to be more intense during certain times of the year. The so-called seasonal peaks, when cluster headache becomes more painful in spring and autumn, while migraine, in the warmer months, until early autumn.
What has been highlighted connects the two forms of headache with circadian rhythms and the primary biological clock. In the presence of an imbalance of the biological clock, not only sleep disturbances occur, but also cluster headaches and migraines.
Migraine – the most common headache
Migraine is the most common form of headache, one that begins initially in the front or side of the head, and spreads. It is usually accompanied by other symptoms, such as above all: nausea, sensitivity to lights and sounds. The duration of the headache is generally between 4 and 72 hours, and presents itself with a throbbing pain involving half of the skull with a noticeable worsening when carrying out even trivial activities or small efforts such as taking the stairs or bending over.
It also tends to get worse in the presence of:
Cortisol and melatonin: the correlation
Two hormones are implicated in this link between circadian rhythms and headaches, and would provide an explanation for the punctual occurrence of pain at the same time of day. Researchers have noted that individuals with headaches generally present lower melatonin (sleep hormone) and higher cortisol (stress hormone) levels. Not only that, they also discovered that some genes related to our body’s biological clock are connected to cluster headaches.
