Our expert says:
I don't think it's serious, unless he was sleeping in this environment night after night. I don't think he needs to see a doctor if he feels fine. But if he has symptoms e.g. dizziness, headache, respiratory tract irritation or feels unwell in any way, then by all means consult your doctor.
