Can a fever be caused by overheating?

[missingthemountains]

DS2 who is 6 months has had a raging temp last couple of nights - he has been poorly recently - (bronchitis, bronchiolitis, cold, teething...) but his temp is down during the day - was wondering if he was just overheating a bit at night? he only has pj's and a grow bag and his room is about 20deg

How high was his temperature? I wouldn't have though it was due to overheating.

100 last night and 103 night before

No, temp not due to overheating. Everyone's temp is higher in the evening. Sounds like it's going in the right direction though!
