I also sleep with blackout curtains, have an eye mask on hand in case those don't do the trick, keep a soothingly scented candle by my bed, and only sip herbal tea after 5 pm.
When I lived on the east coast, during winter I added a humidifier to help with the extreme drying effects of an old radiator. In the summertime I added a fan to help the window air conditioning unit reach the bedroom, and a dehumidifier to keep my sheets from feeling like a damp towel.
Sound extreme? We’ve all heard the studies on how many hours you sleep throughout your life and the importance of a good night's sleep. For me, personally, it comes down to this; I’ve lived in city apartments on busy streets, on the floor below a toddler, and with the worlds noisiest radiator. If I consistently can’t get a good nights sleep I’m cranky, unfocused and tired.
What’s your routine?
