The Story

A study published in the Journal of Sleep Research found that experimental sleep restriction blunted positive emotions and aesthetic experiences when participants viewed abstract artwork. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/42728768/?utm_source=openai))

That matters for designers because critique is not purely intellectual. When tired, we may not only work more slowly; we may experience less pleasure, nuance, and openness in the work we are judging.

A practical Studio Wensday rule: make major taste decisions twice when possible. Use a rested session for direction and a tired session only for administration, file hygiene, or low-stakes iteration.

Studio Wensday Angle

Rest is not separate from taste; it helps produce taste.
