Introduction
In general, persistent drowsiness, fatigue, and lack of energy may be caused by insufficient sleep, lack of physical activity, excessive stress, anemia, hypothyroidism, or other factors, and should be managed according to the specific situation. If drowsiness, fatigue, and lack of energy persist for a long time or are accompanied by other abnormal symptoms, prompt medical attention is advised to establish a clear diagnosis and receive targeted treatment.
Generally, persistent drowsiness, fatigue, and lack of energy may be caused by insufficient sleep, lack of physical activity, excessive stress, anemia, hypothyroidism, and other factors. Appropriate management should be based on individual situations.
1. Insufficient Sleep: Long-term late nights, poor sleep quality, or inadequate sleep duration can prevent the body and brain from getting sufficient rest, leading to symptoms such as fatigue, drowsiness, and low energy. It is recommended to maintain a regular sleep schedule, avoid using electronic devices before bedtime, and develop healthy sleep habits.
2. Lack of Physical Activity: Insufficient exercise may slow down the body's metabolism, impair blood circulation, and hinder the timely delivery of oxygen and nutrients to various tissues and organs, potentially causing physical fatigue and low spirits. It is advisable to engage in regular aerobic exercises such as brisk walking, jogging, or swimming, while avoiding overexertion that may lead to physical discomfort.
3. Excessive Stress: Prolonged exposure to high-pressure or high-intensity work or living environments can cause significant mental strain, depleting psychological energy and resulting in physical and mental fatigue, including symptoms like drowsiness, fatigue, and low energy. Learning effective stress management techniques, such as deep breathing, meditation, and progressive muscle relaxation, can help alleviate tension and emotional stress.
4. Anemia: A reduction in red blood cells or hemoglobin levels in the blood can lead to insufficient oxygen delivery, causing oxygen deficiency in various organs and tissues, and resulting in symptoms such as fatigue, drowsiness, and dizziness. It is recommended to take iron supplements under a doctor's guidance, such as ferrous sulfate tablets or compound ammonium ferric citrate syrup.
5. Hypothyroidism: Insufficient secretion of thyroid hormones can slow down the body's metabolic rate, leading to symptoms such as cold intolerance, fatigue, excessive sleepiness, and impaired memory. Patients may often feel physically sluggish and mentally depressed. It is recommended to take medications such as levothyroxine sodium tablets or thyroid extract tablets under medical supervision.
If persistent fatigue, drowsiness, low energy, or additional abnormal symptoms occur, timely medical consultation is advised for accurate diagnosis and targeted treatment.
