What causes dizziness and a feeling of coldness in the body?

The patient primarily presents with influenza accompanied by dizziness and chills. This type of influenza is commonly caused by infection with the influenza virus and is often associated with a weakened constitution and exposure to cold. Main symptoms include headache, nasal congestion, sneezing, cough, generalized body aches, and fever. It is recommended to drink plenty of water, consume fruits, and follow a light, easily digestible diet—avoiding spicy and irritating foods. Additionally, ensure adequate sleep, abstain from smoking and alcohol, keep windows open for ventilation, and avoid crowded places.
