The baby can watch TV quietly and parents are not bored. They all feel relaxed. When a child was in his infancy, many adults watched television either by holding their children or by putting their babies alongside their cradle.

Watching TV for a long time should open the window

If people often close windows and doors while watching TV, then It is easy to get cancer. In particular, the video hall closed the doors and windows and pulled down the curtains when it was put on television. If the air conditioning was added, it was even more dangerous. A newspaper in Hong Kong also published a warning about "Closing windows to watch TV become susceptible to cancer."
However, there is no need to worry too much about it. If you watch only one or two hours of television with the doors and windows closed, the danger is not great. It's only dangerous if you have a TV for hours and close doors and windows. And as long as the window is opened, this dangerous carcinogenic energy will vanish. Therefore, watching TV for a long time remembers opening windows. Even if it is winter, this must not be ignored.
