If a person often suffers from a headache after waking up, this may be a sign of a serious health problem.

Dr. Yelena Tsaryova, a sleep specialist, points out in an interview with Sputnik Radio that headaches can appear at any time of the day.
But if it appears after waking up in the morning, the cause may be a sleep disorder.
  
She says: “The person may feel a headache after waking up if he does not follow any routine. Because the body is in a state of adaptation.” "Synchronized with changing clock settings. That is, it tries to adjust the sleep cycle so that its end coincides with the time required to wake up. But if awakening occurs during the deep sleep period, waking up is much more difficult than at the beginning or end of the sleep cycle. Therefore, the person feels a headache, malaise, and weakness." .

According to her, a person can feel a headache due to air being trapped in the room. If the morning headache does not go away even if the room is ventilated regularly and a specific sleep routine is followed, the person should consult a doctor. Because this headache may indicate a serious health problem such as sleep apnea.

She says: “The other reason is hypoxia, or oxygen starvation. As a general rule, this condition is caused by snoring, where breathing stops during sleep. Headaches can also be a result of high blood pressure, and stopping breathing can lead to this.” Also, a headache may indicate the body’s internal resistance to the necessity of getting up and doing something. This is often observed in the case of depression.”
