Pittsburgh Sleep Quality Index Questionnaire
All human beings need 7-8 hours of sound sleep every night. Some people can ‘get by’ on less, but that is surviving rather than thriving. It is hard to overestimate the importance of good sleep. Tests have shown that after just a week of disturbed sleep, most people’s intelligence falls to borderline subnormal.
