Over night, with 80% humidity? Are you sure? I’d be close to hospital with that temperature without some kind of AC, or at the very least ventilation… (I’m sensitive to heat). And sleeping with that temperature even with ventilation is going to be very uncomfortable and not relaxing…
Also we’re talking about lows, so this is likely not the temperature inside when there’s no AC, more like 30+C
Temperature is absolutely a problem. Without getting too deeply technical, a heat index above 99F/37C is dangerous even for healthy adults. Las Vegas this week has seen temperatures up to 120F. The forecast today is for a temperature high of 118F/48C (low of 90F/32C overnight), with a relative humidity of 8%. That works out to be a heat index of 111F/44C.
Where I am, today’s high will be 82F, but humidity is sitting at 90%, which is a heat index of 92F.
You can also look at wet bulb temperatures; at a certain point, your body can’t cool fast enough through evaporative cooling, and you’ll die from heat.
I lived through dry summers around 40°C without ACs without a problem my whole 40+ years of life. But 30°C with a high humidity is a different thing. Much comes down to being accustomed to things though naturally. I have friends who grew up in southern China who get problems when the heat is dry.
But people live in areas that get 35+°C every year for several month since the beginning of humanity itself.
Honestly, for me a reason why humans shouldn’t live in such places. For the Europeans here (that have not much clue of weird American units):
80 F = 26.667 C
100 F = 38 C
26? It’s pretty warm, but not too hot.

Then you certanly need ventilation or AC. I just have window open.
The temperature is not a big problem imo. The humidity though.
