很多上班族在下午上班时常觉得精神不振、眼睛模糊,或有轻微的头晕、头痛,往往误以为是疲劳罢了。事实上这可能是因为轻度缺氧,加上大量耗氧所致。此时,很多人会选择喝杯咖啡提提神,但此举并不会改善缺氧。精神亢奋地拼下去,反而让缺氧的时间延长。 Many office workers often feel depressed, have blurred eyes, or have a slight dizziness or headache in their work in the afternoon, often mistaking them for fatigue. In fact, this may be due to mild hypoxia, coupled with a lot of oxygen consumption. At this point, many people will choose a cup of coffee refreshing, but this move does not improve hypoxia. Excitement to fight down, but to extend the time of hypoxia.
