Doctor shows how to 'digital detox'

Dr. Pham Anh Ngan, from the University Medical Center of Ho Chi Minh City, said that "Digital Detox" is a term that has been mentioned for many years, referring to a period of time when a person does not use technological devices. This method directs us to focus on real-life social interactions and limit distractions from the virtual world . Reducing the time spent using digital devices, at least temporarily, can help people eliminate stress stemming from constant connectivity.

Actively setting limits on your screen time allows you to focus your attention on real-life connections, with the people around you, and with yourself.

It is necessary to reduce the time spent using electronic devices during unnecessary activities while eating.

Tips for "digital detox"

According to Dr. Anh Ngan, to limit screen time, we can set time limits for browsing social media. Turn off your phone 30 minutes before bedtime. Seek support from family and friends to let them know you need to limit your use of phones and tablets, and ask for their assistance.

Spending time in green spaces and environments outside of electronic screens will increase your sense of connection with reality. Delete social media apps that you easily access on your phone. Set aside a fixed time each day to browse social media.

Similarly, Dr. Vo Thi Ngoc Thu, from the Neurology Department at Nam Saigon International General Hospital, stated that we all know blue light is harmful to the body, but in modern life, technology devices are an inseparable part of our lives. Therefore, to ensure good health and quality sleep, we should reduce the time spent using electronic devices, especially about 30 minutes before bedtime. Switch screens to night mode or reduce screen brightness. Engage in light exercise or yoga before bed.

"The benefits that phones bring to people's lives are undeniable, but that doesn't mean we can ignore the harms of using them on our health. Excessive use and dependence on phones can be detrimental to your well-being," Dr. Thu warned.

In addition to limiting screen time, parents should also pay attention to the distance children have from the device.

Pay attention to the distance when handling the devices.

Dr. Nguyen Thi Bach Tuyet, an ophthalmologist at Children's Hospital 2 (Ho Chi Minh City), advises that to protect children's health and eyesight, parents should limit their children's use of electronic devices. Children should not watch television for more than two hours a day, and parents should pay attention to the viewing distance.

- Minimum viewing distance = Screen size (in inches) x 2.54 x 2.

- Maximum distance = Screen size (in inches) x 2.54 x 3.

For example, the safe viewing distance for a 42-inch TV is between 2.1 m and 3.2 m.

In addition, children also need breaks, outdoor recreation, and proper nutrition to ensure their health during their developmental stage.
