Does intense sunlight heat cause wilting?

It's strange because i put my usual outdoor plant directly in the sunlight this morning and then I check back like 30 minutes later and it started wilting. The leaves themselves were fine before and when they were wilted it seemed pretty firm still just droopy.
But then when I brought them into some shade they went straight back to normal. It never happened before when i put them in direct light. We've had recent heat waves so it's hotter than normal.

Yes. They more then likely need to be watered. Go by the weight of the pot dry, vs wet. Water them then put them back into the sunlight, and they shouldn't droop.

yah but i just watered them yesterday so it should have enough water...

Well like you said recent hotwaves. Need more watering then you've normally been doing. Trust me I had this same problem a few days ago. Plant out in the sun was sure it had enough water tops were drooping. Put them in the shade it perked back up, so I watered them and put them back into the sun no problems.

Another big factor is pot size, and definitely how big the plant is. Bigger the plant more water.

DAMN THESE HEAT WAVES!!!
