Lego and Temperature

[Legoparticulate]

Hey everybody, I hope you are doing well today.  As a preface, I live with OCD, so please don't judge me if you find this post odd or obvious.

As the summer months approach and the heat rises, I question my Lego collection's safety.  My Lego room's temperature can range from 26 Celsius(80f) to 32 Celsius(90f).  I know TLG states 40 Celsius as the limit however I am still worried this long-term hot temperature would affect my collection.  I am curious if anyone believes the Lego will be fine in this condition or if I should try to drop the temp.  

I apologize if this comes off as a dumb question, but to be honest, I could use the peace of mind.

Nothing to worry about. It won't melt. UV light is a much bigger threat to your stuff as it will inevitably cause the materials to degenerate. The point of keeping things within a certain temperature range with plastics is to avoid micro-warping and/ or in reverse not not lose thermal tension warping intentionally built in. For LEGO both can matter in terms of clutch power and friction when putting elements together. That said, LEGO is being way too cautious. Most ABS types can handle 60 degrees C without any sign of changing notably. Things only get a bit more critical after that with the gloss changing, but even then there's still lots of room before they actually begin to show signs of their structure changing. We're talking more long-term effects here than just a single day of summer heat...
