Introduction

Under normal circumstances, ultraviolet (UV) disinfection lamps in kindergartens should be used for 30 to 60 minutes. As kindergartens are public places with relatively large areas, a longer disinfection time is required. If any discomfort occurs during UV lamp disinfection, it is recommended to seek medical attention promptly to avoid delaying treatment. A UV disinfection lamp is a lighting device that uses the germicidal effect of ultraviolet light for sterilization and disinfection.

Under normal circumstances, ultraviolet (UV) disinfection lamps in kindergartens should be used for 30 to 60 minutes. As kindergartens are public places with relatively large areas, a longer disinfection time is required. The details are as follows:

UV disinfection lamps are lighting devices that utilize the germicidal properties of ultraviolet light for sterilization. In kindergartens, UV lamps are typically used once daily, usually after children have left for the day. Generally, 30 to 60 minutes of exposure is sufficient to kill many common viruses and bacteria.

It is important to note that when using UV disinfection lamps, the lamp must be placed in a position where it can directly illuminate the area being disinfected, or where it can cover the maximum possible area. For effective disinfection, the room should be kept closed during irradiation. Additionally, all individuals must leave the room while the UV lamp is operating. Although UV light effectively kills pathogens, it can also cause harm to the skin and eyes. Therefore, no one should remain inside the room during use.

If any discomfort occurs during or after UV disinfection, it is recommended to seek medical attention at a hospital promptly to avoid delaying treatment.

Is it harmful to the body to be under an ultraviolet disinfection lamp for a few minutes?

Ultraviolet lamps usually refer to germicidal UV lamps, which can kill bacteria and be used for treatment. The extent of the impact on a person exposed to a UV disinfection lamp for several minutes cannot be definitively determined, as the radiation intensity of germicidal lamps varies and thus the harm to the body may differ accordingly. Prolonged exposure of the body to UV lamps may potentially cause skin damage.

Do preschool admission medical checkups require fasting?

Generally, a physical examination for kindergarten admission does not require fasting. The purpose of the examination is to ensure the child's physical health and includes assessments of height, weight, vision, hearing, oral health, and heart and lung function. These tests do not require an empty stomach, so children can undergo the examination after having breakfast or lunch. Additionally, it is important to avoid having girls tie their hair up on top of the head, as this may affect height measurement.

What are the three stages when a child's immunity is the weakest?

Since each child has a different constitution, there is generally no such thing as "the three stages when a child's immunity is weakest." However, periods when children tend to have weaker immunity include around six months of age, weaning time, and when starting kindergarten—during these times, targeted care and treatment may be needed. After birth, most antibodies in infants come from their mothers; because their own immune systems are not yet fully developed, they are particularly vulnerable during this period.

What is the appropriate water temperature in °C for kindergarten children to drink?

It is generally appropriate for preschool children to drink water at a temperature of around 25°C. Since children's oral mucosa and gastrointestinal tracts are relatively delicate, the water temperature should be kept warm and comfortable. Under normal circumstances, the water temperature should be maintained at about 25°C. Water that is too hot or too cold may affect gastric digestive function and could also have adverse effects on the oral mucosa.
