| Levels | Thermal comfort | Division | Characteristics |
|---|---|---|---|
| 1 | More comfortable | MTHI<μ−σ | Colder and more comfortable |
| 2 | Comfortable | μ−σ≤MTHI<μ−0.5σ | Comfortable |
| 3 | Less comfortable | μ−0.5σ≤MTHI<μ+0.5σ | Comfortable |
| 4 | Uncomfortable | μ+0.5σ≤MTHI<μ+σ | Hotter and more uncomfortable |
| 5 | Extremely uncomfortable | MTHI>μ+σ | Hot and suffocating |
