Why would reptiles like dinosaurs be affected by cold temperatures more than mammals?

Reptiles are more affected by cold because their bodies don't regulate their temperature like mammals. Almost all mammals (and some dinosaurs it is believed) have a specific temperature which their bodies maintain or try to maintain. For humans it is about 98.6 degrees. Other mammals and animals with this ability have differing body temperatures. So when it is cold, reptiles tend to stiffen up in response. Their metabolism drops correspondingly. They become slower in response. Reptiles are not found in areas where freezing temperatures are common.

Are dinosaurs the oldest mammals?
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
Why aren't dinosaurs mammals?
Dinosaurs and mammals evolved from two separate branches of reptiles. Mammals evolved from synapisid reptiles (all of which are not extinct) while dinosaurs along with the modern branches of reptiles evolved from sauropsids. So dinosaurs are more closely related to modern reptiles than they are to mammals. In more recent years scientist tend to agree that birds are in fact a surviving branch of dinosaurs.
Are dinosaurs related to mammals?
No, dinosaurs are more related to reptiles and birds.
Are people mammals or reptiles?
There are more mammals because of the dinosaurs.

Only mammals have sweat glands. Dinosaurs were reptiles, so they did not have sweat glands.
