Five reasons why you might wake up unexpectedly in the middle of the night

Sometimes, sudden awakenings at night are explained by a temporary problem, but the cause may be a chronic disorder that requires clinical treatment.

Sleep apnea.This is one of the most common reasons why you may wake up unexpectedly in the middle of the night. Apnea is characterized by a person's breathing being interrupted while sleeping, with pauses and loud snoring. During these pauses, the person's brain experiences oxygen starvation, and it is believed that people with apnea may be prone to brain diseases, including dementia.

Urinary urges.Many doctors say that a healthy body should be able to withstand eight hours of sleep at night without waking up to go to the toilet. If the urge to urinate still occurs, even though a person does not drink much water and does not take medication, he may have an overactive bladder, diabetes, prostate problems (in men), or heart disease.

Sweating. Waking up in the middle of the night due to profuse sweating can be observed with acute respiratory viral infections, diabetes and other endocrine disorders, and cancer.

Alcohol and food. According to studies, alcohol consumption can disrupt the circadian rhythm and shorten the sleep cycle – so after drinking the night before, you can unexpectedly wake up at an inappropriate time. As for food, heavy meals eaten shortly before bedtime can disrupt digestion, cause indigestion or bloating, which also act as an alarm clock.

Blue light overdose. Smartphones emit blue light, which is known to negatively affect the sleep-wake cycle. Constant use of gadgets, especially in the evening and before bedtime, exposes the body to intense blue light, and this can disrupt the mechanisms of falling asleep and waking up.
