| Setup factor | Possible heat effect |
|---|---|
| Warm rooms and humidity | Open windows after dark when outdoor air is cooler than indoor air; keep humidity below 60%, ideally 30% to 50%. |

| Covers and protectors | One protector example lists materials and care instructions, but the facts do not establish a general heat effect. |
