It starts to make sense when we account for our body’s reactions.
The human body must work much harder at some of these temperatures, than at others.
Closing a 3 degree gap between ambient and ideal temperature has a very different physical cost than trying to adjust to a 30 degree gap.
And at some certain point, the body’s natural defenses start to run out of options (closing pores, adjusting heart rate, adjusting breathing, increasing or reducing sweat or activity level). Once the body applies every available defense technique, then each extra degree (now with no further defense to apply) may become dramatically more harmful.
This is also why wind chill matters. The actual amount of heat being lost by a body is much more relevant to safety than simply measuring the ambient temperature.
