Why does son resist Cleaning as chore worsening study stress?

My son has intense study stress and resists the recommended evening 'Cleaning' practice because he feels it's just another chore and a waste of study time. His father is worried this resistance is preventing him from dealing with his accumulated anxiety and stress. My name is Anjali. DOB: 9th October 1975. Time: 7:50 PM. Location: Delhi. Should I stop enforcing the ritual entirely, or find a way to reframe it as a reward? His name is Aryan, DOB 10th March 2006.
