Why are boat runners short-lived?

There are three points in the short-lived analysis of ship runners.

Reason 1. Working at sea for a long time is very harmful to your health.

High salt, high humidity and high temperature at sea will corrode even ordinary steel, not to mention people! Therefore, the steel used in warships such as aircraft carriers is special steel, and people have lived at sea for a long time. What a shame.

The second reason is that working at sea for a long time has reversed the rhythm of the human biological clock.

According to the laws of nature, people should work at sunrise and rest at sunset. However, there is no day or night when the fishing news comes, and there is no time limit for typhoons and hurricanes. Therefore, the disorder of human internal biological clock in the marine environment will inevitably lead to the irregularity of human endocrine and damage the body.

Reason 3: Life at sea is as long as half a year or a year, and as short as one month or several months. Isolation will affect people's mental health.

Working monotonous hours for a long time may even cause people's auditory hallucinations and hallucinations, which is harmful to people's health.

Running a boat is going out to sea and working on a boat.
