Why do I always feel drowsy and lack energy in summer?

Generally, feeling constantly drowsy and fatigued during summer may be caused by factors such as electrolyte imbalance, anemia, or insufficient cerebral blood supply. Treatment can be carried out through medications or improvements in lifestyle habits.

1. Electrolyte Imbalance: Electrolyte imbalance may result from excessive water intake, prolonged inadequate food intake, or similar factors, potentially leading to symptoms such as persistent drowsiness and fatigue, dizziness, and weakness during summer. Medications such as calcium gluconate oral solution or potassium citrate granules may be used under medical guidance to alleviate these symptoms.

2. Anemia: Anemia may be caused by unbalanced diet, abnormalities in hematopoietic stem cells, or other factors, possibly resulting in symptoms like constant drowsiness and fatigue, and difficulty concentrating during summer. Treatments may include dextran iron dispersible tablets or ferrous fumarate granules, taken as directed by a physician.

3. Insufficient Cerebral Blood Supply: Inadequate blood flow to the brain may be due to cerebral arteriosclerosis, irregular lifestyle habits, or other causes, potentially causing symptoms such as persistent drowsiness and fatigue, and unsteady gait during summer. Medications such as nimodipine tablets or vinpocetine tablets may be prescribed by a doctor for treatment.
