Turn your shower into a sauna
"Just turn your shower on and run it at its hottest temperature for about 20 minutes. While the water is running and the steam is building, take a warm washcloth and spray with your favorite relaxing oil. (Lavender, vanilla or rosemary) When you step into your shower, put the washcloth up to your face and take a deep breath of your soothing, oil-scented steam. It's a great way to unwind right before bed—and it also helps clear up sinuses."
