The arrival of autumn signals the end of children's summer vacations as they return to school for group learning. This season also marks the peak period for influenza. Many people have their own methods for preventing colds, such as sucking on ginger slices, drinking ginger and brown sugar water, or taking Banlangen. However, many fall into common misconceptions about influenza prevention.
1. Using Medical Disinfectants
Some individuals employ hospital-grade alcohol, peracetic acid, or sodium bicarbonate solutions to disinfect homes for flu prevention. Wang Tong advises: "Generally, even during flu season, excessive home disinfection isn't necessary. If an infectious patient is present, moderate use of chlorine-based disinfectants followed by rinsing with clean water and drying is sufficient."This is because alcohol is a medium-strength disinfectant. Commonly used at 75% concentration, it can kill most bacteria, fungi, and viruses, but it cannot eliminate bacterial spores or certain hydrophilic viruses like hepatitis A and poliovirus. Furthermore, dust can settle back onto surfaces after wiping, re-contaminating areas treated with alcohol.Peracetic acid and soda water, on the other hand, are highly acidic and possess strong oxidizing properties, posing safety risks to humans. They should only be used under professional guidance and are unsafe for general household use. 2. Taking Banlangen to Prevent Flu From SARS to the current H7N9 avian flu, whenever respiratory infectious diseases strike, people often turn to Banlangen.Some households keep Banlangen stocked, and at the first sign of flu, they immediately brew two packets for each family member. While Banlangen does possess antiviral properties, it is a medication with potential side effects. Moreover, it cannot prevent the flu, and individuals with spleen-stomach deficiency-cold should avoid it. Overconsumption may also cause adverse reactions affecting digestive and hematopoietic functions.
3. Vinegar Steaming for Disinfection and Flu Prevention
Steaming vinegar in rooms to prevent colds became extremely popular during the SARS outbreak. Even today, many still believe that sealing windows and doors while boiling vinegar in clay pots or similar containers can disinfect and kill germs.Whether "vinegar fumigation" can treat viral infections remains highly controversial. No scientific evidence supports its reliable bactericidal or virucidal effects. Prolonged fumigation in enclosed spaces can elevate airborne vinegar concentrations, causing respiratory distress, nausea, and damage to skin and respiratory mucosa."Acetic acid irritates respiratory mucous membranes, potentially worsening conditions like bronchitis, emphysema, or asthma. Therefore, households with individuals suffering from chronic respiratory diseases should avoid vinegar fumigation."
4. Getting a flu shot prevents colds
Influenza is an acute upper respiratory infection caused by influenza viruses.The flu vaccine is only effective against one or several specific influenza viruses and does not protect against the common cold caused by exposure to cold temperatures. It is also important to note that the flu vaccine's effectiveness lasts only one year. Due to constant viral mutations, the composition of the annual flu vaccine varies, necessitating a new vaccination each year. After vaccination, it takes approximately two weeks for the body to develop antibodies.During this period, individuals with weakened immunity may still contract the flu if exposed to the virus.
How to Properly Prevent Colds
Preventing colds begins with maintaining cleanliness at home. Some elderly individuals tend to accumulate clutter or even collect discarded items from outside. Such practices easily introduce pathogens into the home, compromising health. Bedding should be regularly aired out to prevent viral invasion.
Frequent handwashing is essential, especially after contact with nasal secretions. Always wash hands immediately with running water—do not simply wipe them. Ensure thorough cleaning of palms, backs of hands, and between fingers.
Friendly reminder: Stay hydrated, maintain moderate exercise, ensure adequate sleep, and avoid crowded places—these are the best ways to prevent colds. Wishing you a pleasant life!
