Sounds awful :shock: Even if you weren't pregnant.

I am over cautious about overheating because I heard it's not very good for the baby, so I would not be doing this in your situation. Last weekend was only about 30 degrees and I was doing some painting outside on the full sun. I only lasted 30 minutes before I felt awful and just way too hot. 6 hours would be pure torture As for the fainting, I have almost fainted twice already in this pregnancy just due to being too hot :shock: so it's a possibility.

Maybe if you have shade and make sure you have lots of drinks it won't be too bad. Is there no way you could do it sitting down? I am sure people would understand as you're pregnant...
