Rinse your mouth after three meals
A study by Kyoto University in Japan found that rinsing your mouth three times a day reduces the risk of catching a cold by nearly 40%. It is recommended to rinse your mouth with light salt water after three meals a day to kill cold viruses.
Wash your hands after shaking hands
When a cold patient sneezes or coughs, they may spray the virus onto their hands. If you shake hands with such a person, you are more likely to be infected with the virus. During the early winter season when colds are prevalent, it is advisable to wash your hands soon after shaking hands with others. In addition, doorknobs, bus handrails, and other surfaces may be contaminated with cold viruses. You should wash your hands as soon as possible after touching them.
Add some spice
The capsaicin in chili peppers can improve nasal airflow, and the allicin in garlic can kill cold viruses. Eating them together can help prevent and treat colds.
Eat oatmeal for breakfast
Oatmeal is rich in various vitamins that can boost immunity, as well as trace elements like zinc and iron. Research has found that people who eat oatmeal for breakfast have a smaller chance of catching a cold than those who don't.
Eat more green leafy vegetables
The Babraham Research Institute at the University of Cambridge in the UK found that eating more green leafy vegetables can boost immunity. The effect is even better with cruciferous vegetables like broccoli and cauliflower.
Eat more sea fish
Some people believe that consuming vitamin C can prevent colds or speed up recovery. However, Australian scientists have found that vitamin C does not prevent colds. Sufficient intake of vitamin D, on the other hand, can strengthen the immune system and help prevent colds. Sea fish such as salmon, eel, and sardines, as well as mushrooms, are rich in vitamin D and can be eaten in moderation.
