Human thermal comfort: seasonal change in optimum effective temperature Compare the optimum effective temperature for human comfort in winter versus summer. Choose the correct relation.

Concept/Approach
The effective temperature concept accounts for dry-bulb temperature, humidity, and air motion to reflect perceived comfort. Seasonal clothing and acclimatization shift the comfort zone.

Reasoning
In winter, lower air movement and heavier clothing lead to a slightly higher optimum effective temperature compared to summer, where higher air movement and lighter clothing make a lower effective temperature feel comfortable.

Final Answer
Higher in winter than in summer
