- Tooth Brushing -

The key word is Flu.
There is close relationship between tooth brushing and flu.

Wrong way of teeth brushing on a winter morning:
Before you go out, you brush your teeth quickly.
Why is this wrong?

If you don’t brush your teeth properly, the chance of getting flu increases rapidly.

Why does brushing teeth prevent flu?

The best way of brushing teeth in winter morning:
Timing is important.
When you wake up, bush your teeth first in the morning.
Why?

Because there are a lot of flu supporting enzymes called protease in the mouth. Protease is an enzyme caused by bacteria in the mouth. The mucus membrane of the throat plays a role of preventing virus infection. Protease destroys the wall of the mucus membrane and makes it easy to infect flu viruses. Therefore, protease is a bad guy who supports the infection of flu viruses.
​(Fig. 1 & 2)

When you are up, bacteria are suppressed by saliva. On the other hand, while you are sleeping, the secretion of saliva is not much and dry, increasing bacteria in the mouth.

If you eat something without tooth brushing, protease go into your body with food. Protease destroy the protein wall of the mucus membrane in the throat and supports the invasion of flu viruses. A flu virus attached on the throat invades the body in 20 minutes.

So please brush your teeth first in the morning.
