Why does my head feel swollen when it's hot and stuffy, and what should I do about it?

Generally, experiencing a feeling of head distension when hot and stuffy may be caused by physiological factors or pathological conditions such as hypoglycemia or hypertension. Appropriate treatment should be based on the specific cause. Details are as follows:

1. Physiological Factors

If there is a significant difference in temperature and humidity between indoor and outdoor environments, or if mental stress is excessive, physical discomfort including the aforementioned symptoms may occur. These symptoms usually resolve effectively with rest and do not require special treatment.

2. Pathological Factors

1) Hypoglycemia

Low blood glucose levels can lead to hypoglycemia, causing symptoms such as headache, dizziness, and blurred vision. These symptoms may worsen in hot and stuffy conditions. It is recommended that patients promptly consume some sugary foods to help improve their hypoglycemic condition.

2) Hypertension

Hypertension is a clinical syndrome characterized primarily by elevated systemic arterial pressure, increased resistance in peripheral small arteries, and varying degrees of increased cardiac output and blood volume. Patients typically experience symptoms such as dizziness, headache, blurred vision, tinnitus, insomnia, and fatigue, which may intensify in hot and stuffy conditions. Patients are advised to take antihypertensive medications such as nifedipine tablets or captopril tablets as prescribed by a physician. Regular appropriate exercise is also recommended in daily life to help control blood pressure.

Besides the above, other possible causes include migraine, stroke, and traumatic brain injury. It is recommended that patients seek timely medical attention when discomfort occurs to avoid delays in treatment. Additionally, maintaining a light diet and ensuring adequate rest are important in daily life.
