A cold, also known as an upper respiratory tract infection, typically manifests different clinical symptoms depending on its triggering factors. Generally, most patients with a cold exhibit symptoms like nasal congestion, runny nose, and sneezing due to a viral infection. Therefore, for such patients, personal hygiene is crucial. Additionally, it is important to ventilate rooms by opening windows and to avoid public places as much as possible to prevent spreading the infection to others with weaker immune systems. These cold sufferers are also advised to avoid spicy and irritating foods. Drinking plenty of water daily and consuming fresh vegetables and fruits high in vitamins is recommended. Consumables like apples, pears, water chestnuts, grapes, and kiwis, which are rich in vitamins and nutrients, should be eaten regularly to help enhance the immune function of these patients.
