Why do I experience insomnia, generalized itching, and weakness?

Insomnia, generalized itching, and weakness can be caused by various factors, as detailed below:

1. Insomnia: Difficulty falling asleep or maintaining sleep may result from multiple causes, including environmental factors (e.g., cramped or overly spacious sleeping quarters, noisy sleeping environment), physical factors (e.g., pain, generalized itching), psychological factors (e.g., anger, excessive excitement), and dietary or medication-related factors (e.g., stimulants such as tea, coffee, cocoa, or antidepressants such as cocaine). Chronic insomnia may be associated with anxiety or depressive disorders.

2. Weakness: Physical weakness can be caused by multiple factors, including insufficient sleep, depression, nutritional deficiencies, excessive exercise, and certain chronic diseases (e.g., liver disease, thyroid dysfunction, anemia).

3. Generalized itching: Medically referred to as pruritus, this may be caused by allergic reactions (e.g., to clothing or environmental allergens), dry skin, skin diseases such as eczema or dermatitis, or systemic conditions such as chronic liver disease, kidney failure, or diabetes.

These symptoms may be interrelated or exist independently, and the exact cause must be determined through detailed medical history, physical examination, and necessary laboratory tests. Therefore, when experiencing these symptoms, it is advisable to seek timely medical attention for comprehensive evaluation to identify the exact underlying cause and receive targeted treatment. Additionally, maintaining healthy lifestyle habits, such as regular sleep patterns, balanced nutrition, moderate exercise, and effective stress management, can also have a positive impact on alleviating symptoms.
