Follow these tips if you’re painting indoors:

• A well-ventilated house makes for a healthier home under any circumstances. But it becomes even more important when you’re tackling an interior painting project. 
• To avoid health problems when you’re painting the inside of your home:
• Schedule painting for dry periods in the fall or spring when it’s easier to leave windows open for ventilation.
• Keep windows wide open, as weather permits, for two or three days after painting to avoid exposure to paint vapors and to restore your home’s good air quality.
• Use window-mounted electric fans to exhaust vapors from the work area. Make sure the fans cannot fall out of the windows.
• If you live in an apartment, let your adjoining neighbors know you’ll be painting, and advise them to open their windows too.
• If you’re doing the job yourself, take frequent breaks. After you’ve finished, stay out of the freshly painted rooms for two to three days. Keep children and anyone with a breathing problem away from the area.
