how long can a bearded dragon stay out of her terrarium?

[riley2012]

Hi.

I have a female bearded dragon, Riley, who is about 1 year and three quarters old.

Riley brumated for close to 3 months. She came out of brumation a week ago, and has been very active since then.

She seems to want to come out of her terrarium frequently. I think that's what she wants, because she bumps against the glass, and when I take her out, she's not stressed and is very active.

I have a safe environment where I can monitor her, and she can run around in a large, open space.

How long can I keep Riley out? The temperature in my home is 72 degrees. How long can she safely stay out in the relatively cold temperature? Also, is it ok to take her out multiple times per day, giving her time to warm up in her terrarium in between?

Thanks!
