Absolutely, sleeping too hot can ruin a good night's sleep because you wake up in the middle of the night, there's sweat all over the mattress.
You can't sleep, you toss and turn, you bring the covers on, you throw them off. Sleeping too hot is miserable.
Ever slept in a hotel room where the air conditioning was broken? Miserable all night long. Same way with a hot mattress.
