What causes constant drowsiness and lack of energy during the day?
Generally, feeling drowsy and fatigued during the day may be related to irregular作息, sleep disorders, neurasthenia, hypothyroidism, depression, and other factors. It is recommended to seek medical attention promptly and receive appropriate treatments such as lifestyle modifications or medication under a doctor's guidance. Specific analyses are as follows:
1. Irregular作息
Staying up late for prolonged periods, high work pressure, and life dissatisfaction may lead to irregular作息, causing excessive carbon dioxide production in the body and insufficient brain rest, potentially resulting in persistent daytime drowsiness. Daily routines should focus on developing healthy作息 habits, ensuring adequate nighttime sleep. It’s also important to relax mentally and avoid negative emotions.
2. Sleep Disorders
Sleep disorders may be associated with poor lifestyle habits, negative emotions, environmental factors, or medication effects. Functional impairments during sleep and reduced sleep quality can lead to persistent daytime drowsiness and fatigue. Lifestyle adjustments are necessary, including avoiding stimulants such as coffee and strong tea before bedtime.
3. Neurasthenia
Emotional instability, sensitivity, chronic insomnia, and excessive stress may easily lead to neurasthenia. Patients often experience mental fatigue, resulting in poor daytime alertness, commonly accompanied by symptoms such as exhaustion, vivid dreams, and easy arousal during sleep. Patients may take medications such as Anshen Bunaoye (calming and nourishing brain liquid), Zaoren Anshen Capsules, or paroxetine hydrochloride enteric-coated sustained-release tablets as directed by a physician.
4. Hypothyroidism
Hypothyroidism is primarily caused by autoimmune damage, iodine excess or deficiency, or pituitary/hypothalamic disorders. Reduced levels of thyroid hormones slow down the body's metabolic rate, which may result in daytime drowsiness and fatigue, often accompanied by cold intolerance, slowed reactions, and memory decline. Patients may be treated with medications such as levothyroxine sodium tablets, thyroid tablets, or hydrocortisone injection as prescribed.
5. Depression
Introverted personality, genetic predisposition, or major stressful life events may contribute to depression. Persistent low mood, combined with insomnia induced by antidepressant use, may lead to the aforementioned symptoms. Other common symptoms include depressed mood, reduced energy, cognitive difficulties, and somatic complaints. Patients may take medications such as maprotiline hydrochloride tablets, clomipramine hydrochloride tablets, or paroxetine hydrochloride tablets under medical supervision.
In daily life, it is important to maintain regular作息, appropriately relax the mind, adopt a positive mindset when facing challenges, and engage in regular physical exercise to help alleviate emotional stress.
