Why do I always wake up feeling inexplicably irritable every morning?

Generally, if you wake up every morning with unexplained irritability, it may be caused by poor sleep quality, disrupted sleep cycles, anxiety disorder, hyperthyroidism, neurasthenia, or other reasons. If symptoms persist, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific causes are analyzed as follows:

1. Poor Sleep Quality

Frequent awakenings at night, excessive dreaming, or snoring can prevent the brain and body from fully resting, leading to fatigue and irritability upon waking. Maintain a regular sleep schedule, avoid electronic devices one hour before bedtime, create a quiet and dark sleeping environment, and consider drinking warm milk before bed to promote sleep.

2. Disrupted Sleep Cycle

Frequent changes in wake-up times disrupt the body's circadian rhythm, causing the body to be awakened during unnatural phases of sleep, which can trigger mood swings. Fix your daily wake-up and bedtime, even on weekends, and gradually adjust your biological clock to a stable state.

3. Anxiety Disorder

Long-term psychological stress leads to accumulated anxiety. Symptoms become more pronounced upon waking when the sympathetic nervous system is activated, manifesting as unexplained irritability and palpitations. Medications such as sertraline hydrochloride tablets, paroxetine tablets, or venlafaxine extended-release tablets may be taken under medical guidance, along with psychological counseling.

4. Hyperthyroidism

Excessive secretion of thyroid hormones accelerates metabolism and increases nervous system excitability, leading to morning symptoms such as irritability, sweating, and palpitations. Medications such as methimazole tablets, propylthiouracil tablets, or carbimazole tablets should be used according to medical advice, with regular monitoring of thyroid function.

5. Neurasthenia

Long-term mental stress causes the nervous system to become easily excited yet easily fatigued. Upon waking, neurological dysfunction may lead to irritability and difficulty concentrating. Under medical guidance, medications such as oryzanol tablets, vitamin B1 tablets, or estazolam tablets may be used. Avoid chronic sleep deprivation and excessive mental exertion.

Daily strategies such as simple stretching and breathing fresh air upon waking may help alleviate mood; maintain a light diet and avoid consuming stimulating beverages like strong tea or coffee in the morning; engage in moderate daytime exercise to relieve stress. If irritability persists for more than two weeks and affects daily life, prompt medical consultation is necessary to identify the underlying cause.
