Answers:    paint adjectives your furniture to match (like white), paint your walls too for a huge alter! make a duvet cover for your quilt using fabric you resembling or you can probly find a set of cool sheets (bigger than your bedspread size) and stitch those together for the duvet cover. sew up some throw pillows surrounded by the colors you like, engender some floor pillows also for when you have friends over, seize one of those bed nets to suspend from the ceiling, get a lava storm lantern or glitter light, upgrade your lampshades with cool fabric and decorative fringe along the bottom, I hung Christmas lights around my room when I be younger and I thought it looked super cool. check out thrift stores to find stuff you can use- shelves, chairs, vases, frames, pictures-whatever!! you can spruce up the stuff you find next to paint, glitter, fabrics- thrift stores other have really well-mannered finds!!!!
Is outmoded paint risky to our robustness?
Buy a huge room air conditioner, that should maintain it very cool
