What is shift in demand?
​

Students wrote down their worries as well as possible solutions.

Explanation:

Students usually keep their diaries in which they write everything that only them can know and for them this is easier because it also maintains confidentiality.

They take everything out as they write it and it gives them that calm feeling and feeling of being in control of their life which reduces the stress or the pressure that they may put on themselves .

This may relax them and give them a peaceful sleep as they tackle everything in writing and find resolutions.
