Perhaps you wake up every day at three in the morning without any reason, as if your mind is equipped with a silent stimulus that wakes you up every night, despite your urgent desire to sleep for eight full hours.

Writer Markham Hyde says in his report published on the American "Medium" website that everyone wakes several times every night, and that this alertness is usually very short and sometimes foggy, to the point that the brain does not remember it in the morning.

Michael Perlis, director of behavioral sleep medicine at the University of Pennsylvania's Perelman School of Medicine, explains that an adult human wakes seven to 15 times every night.

He says that it is normal and that people usually do not remember these moments because it lasts from a few seconds to only a few minutes, and it often coincides with the transition from one sleep phase to another, stressing that a person tends to change his body position when he awakens this short awakening, and this is something good.

Perlis adds that sleep-related anxiety is one of awakening that can be long and disturbing for some if one is worried about getting a good night's sleep.

Emotional reaction
He says that the brain may be on high alert for wakeful periods, and when one of these blurry awakenings occurs, the anxious brain notices it and makes an emotional response, explaining that this can cause the person to wake up fully awake for a longer period than normal.

The writer stated that medical problems also lead to one's awakening at a certain hour, and Perlis stated that gastroesophageal reflux disease can cause "midnight insomnia".

Another symptom of gastroesophageal reflux is persistent coughing or heartburn, but Perlis says these symptoms are not always evident during the day.

The writer indicated that sleep apnea is another reason for night awakening.

"This disorder is much more common than most people realize, and for those who suffer from this disease, the throat muscles relax during sleep, which leads to the closure of the air passages," said Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona Medical School in Tucson. Then breathing can stop for ten seconds or more, causing the sleeper to wake up.

And if the awakening in the middle of the night is not regular or severe, he advised Perlis to avoid sleeping late, avoid daytime naps, and not try to make changes to the daily routine to make up for lost sleep hours, this will help solve the problem in a period of two to five days.
