Is it normal to feel sleepy during the recovery phase of influenza B?

During the recovery phase of influenza B, excessive sleepiness is a normal phenomenon. Patients with influenza B often feel fatigued and lethargic, leading to an increased tendency to sleep. When patients are in an immunocompromised state, their bodies may shift metabolism toward utilizing fats and carbohydrates, which can make them feel even more drowsy, resulting in pronounced sleepiness. Conversely, as immune function improves, this condition gradually resolves, helping restore normal sleep patterns. Therefore, during the recovery period of influenza B, excessive sleepiness is considered normal. As long as patients follow medical advice, take prescribed medications, adjust their lifestyle habits, and maintain a regular and healthy diet, their sleep patterns will slowly return to normal.
