Is it necessary to standing desk?

The above picture is listed according to some overseas health websites, the harm of sitting for a long time, standing for a long time and the benefits of standing and working. Since sitting for a long time and standing for a long time are not suitable, is it relatively healthier and more efficient to adopt the office mode of sitting and standing alternately? I have searched a large number of websites at home and abroad, and what I have seen so far are basically good, but there is no statistical basis.

Judging from my own experience for more than a month, my subjective conclusion is that the office mode of sitting and standing alternately is indeed beneficial, which can obviously feel the reduction of waist pain and improve work efficiency.
My own standing time is roughly one hour, about twenty minutes, and then I stand for a while when I am sleepy and after dinner.
In order to achieve rapid sitting and standing alternation without affecting the working hours, it is necessary to introduce the Standing Desk.
