Light scented candles.
Pick up a few of your favorite scented candles at specialty stores or even at the grocery store. Let the candle’s inviting scent fill the room. If safety’s a concern, purchase a candle warmer to scent the room without a flame.
Invest in an air purifier.
Mold, pet dander, and seasonal allergies can disrupt your breathing giving your body more stress to deal with. An air filter in your bedroom will clean the air and help you to breathe and sleep easier.
