People are living in better conditions nowadays, so they get checked when something is wrong with their body. Sometimes, though, the body sends out health alerts that are not obvious and occur when you are not conscious – at night. Dizziness – infection in the ear If you wake up at night feeling dizzy and the ceiling of the house is spinning, you may be suffering from benign postural vertigo. Most patients are women over the age of 50, and the cause of the disease is the loss of calcium carbonate crystals in the inner ear due to inflammation or infection, which disrupts the balance system in the ear and sends confusing messages to the brain, which in turn leads to vertigo. Suggestion: Sleeping on your back with a raised pillow can help stabilize your head and prevent vertigo, and in severe cases, you should go to the hospital for otolith resetting. Headache – Headache Disorder or Teeth Grinding Disorder Timing Headache Disorder is mostly seen in the middle-aged population, with headaches coming on regularly every night, usually from 1 to 3 am. Cluster headaches also come on at regular intervals, presenting as a throbbing pain at the back of one eye. Not drinking enough water during the day can also lead to nighttime headaches. A dull ache in the jaw upon waking may be due to nighttime teeth grinding. Nighttime teeth grinding may also lead to earaches and headaches. Suggestions: Headache sufferers should go to the hospital, and people who grind their teeth at night are advised to wear a mouth guard while sleeping. Difficulty in breathing – asthma or heart disease Asthma attacks at night can wake up sleeping patients. When the patient lies down, the airways are more likely to collect mucus, increasing the pressure in the lungs and leading to poor whistling. If you wake up suffocated two hours after going to sleep, it may be a sign of heart disease or even heart failure. Suggestion: When this happens, you should actively seek medical attention. Cough – acid reflux The main reason for waking up at night with a cough during sleep is due to acid reflux that irritates the esophagus. Gastroesophageal reflux can easily occur when you lie down after eating. Excessive accumulation of abdominal fat and pressure on the abdomen are especially likely to lead to acid reflux. Suggestion: It is best not to eat before going to bed, especially fatty foods. Also elevating your pillow can help prevent acid reflux. Half asleep and half awake – sleep whistle pause The part of the brain responsible for consciousness in the light sleep state can still work, and can even talk, get up, but not fully awake, in a state of half asleep and half awake. If this happens frequently, it may be a sign of sleep problems such as sleep apnea. Suggestion: Losing weight, quitting smoking and reducing alcohol consumption can help improve sleep apnea. Night sweats – hormone disorders People often think that a little drink before bed can help you sleep, however, alcohol will make the skin vasodilatation, easy to lead to night sweating. In addition, women’s premenstrual, menstrual or postmenopausal estrogen levels drop, can also lead to night sweats. Night sweats in men may be due to low androgen (testosterone). Androgens play an important role in controlling body temperature. Suggestion: drink less alcohol before bedtime and take hormone supplements as directed by your doctor. Leg cramps – poor circulation in the lower extremities The main causes of muscle cramps in the legs at night include. Peripheral vascular diseases and high blood lipids leading to thrombosis and partial obstruction of blood vessels. 2. Pregnancy or excessive exercise. Both of these conditions lead to lower levels of calcium and magnesium in the body, which are critical for muscle contraction and stretching. 3. Taking certain medications such as statins, which are lipid-lowering drugs. One study found that statins increase the risk of muscle cramps by 20%. Suggestion: Stretching exercises, taking a hot bath and drinking a glass of warm water before going to bed can help alleviate the problem of leg cramps at night. Thirst – Hyperglycemia or Uremia Old thirst at night can be a symptom of uremia, in which the patient’s body is unable to regulate fluid levels due to a lack of antidiuretic hormone, and symptoms are exacerbated at night. Waking up feeling thirsty can also be a symptom of uncontrolled diabetes, as high blood sugar levels can trigger a feeling of thirst. Other symptoms include weight loss, blurred vision and excessive urination, especially at night. In addition, a tendency to open your mouth during sleep can also lead to thirst upon awakening. Suggestion: Go to the endocrinology department of the hospital for a relevant examination. Frequent nightmares – drug side effects Stress is the main cause of nightmares, in addition to antidepressants and beta-blockers and other drugs can also affect the natural sleep cycle, but also aggravate the symptoms of palpitations. Suggestion: Relieve stress and find a doctor to adjust your medication in time.
