What causes dizziness when going outdoors after prolonged exposure to air conditioning, and what should be done about it?

Dizziness when going outdoors after prolonged exposure to air conditioning may be due to physiological factors, and symptoms usually subside with appropriate rest. It could also result from conditions such as upper respiratory tract infection or hypertension, which require proper medication. The specific analysis is as follows:

I. Physiological Factors

Prolonged use of air conditioning without adequate indoor ventilation can lead to relative hypoxia. When stepping outdoors, dizziness may occur. Symptoms typically improve after appropriate rest.

II. Pathological Factors

1. Upper Respiratory Tract Infection

Air-conditioned environments are relatively enclosed, which may facilitate the spread of influenza viruses, potentially causing dizziness upon going outside. Treatment should follow medical advice and may include medications such as amoxicillin dispersible tablets, penicillin V potassium tablets, or oseltamivir phosphate capsules.

2. Hypertension

Prolonged exposure to air conditioning may cause abnormal blood pressure. When going outdoors, rising blood pressure increases stress on cerebral blood vessels, leading to dizziness. Medications such as nifedipine tablets, levamlodipine besylate tablets, or nicardipine hydrochloride injection should be used under medical supervision.

In addition to the above causes, dizziness may also result from insufficient cerebral blood supply, cervical spondylosis, Ménière's syndrome, or other conditions. Patients should seek timely medical evaluation and receive standardized treatment. Medication must be taken as prescribed and should not be self-administered.
