Normally through a night’s sleep, the morning should be the most energetic time period for people, but if patients still have symptoms of sleepiness, fatigue and weakness in the morning, consider the following reasons: First, consider whether the patient’s sleep time is too short, such as patients staying up late or poor sleep quality, light sleep, in sleep disorders, patients will still feel very much when they wake up in the morning sleepy and sluggish. Second, consider whether the patient has sleep apnea and snoring at night, resulting in the brain being in a chronic state of ischemia and hypoxia, and the patient will feel sleepy in the morning. Third, consider whether the patient may have eaten too much at breakfast, resulting in the stomach needing more blood to digest food, and the blood supply to the brain will be relatively insufficient, so the patient will also show symptoms of sleepiness in the morning. Fourth, also consider whether the patient’s sleep environment at night is not good, such as poor air circulation, the patient’s water intake at night is not enough, there may be a lack of water and lead to the patient’s metabolism is slow, the brain blood supply lack of oxygen, the morning will also have a strong feeling of sleepiness.
