There are many reasons why someone might always feel sleepy or tired. Common causes include not getting enough high-quality sleep, poor sleep habits, stress, nutrient deficiencies, underlying health conditions, lifestyle factors like diet and exercise, and certain medical problems such as sleep apnea or thyroid issues. Mental health issues such as depression can also contribute to persistent fatigue. Cutbacks in caffeine or alcohol, managing stress, and seeing a doctor for persistent tiredness can help address the issue. If tiredness continues without clear explanation, it may be a sign of a medical condition requiring professional diagnosis and treatment.
