You might check for light pollution when you start to wonder "Why can't I seep?" A recent article from DeliciousLiving.com explores light pollution as the culprit. You would have to live way out in the boonies to experience a truly dark night. Most people in the US live in light polluted areas.
Experts say that we need to sleep in an environment that has little artificial light. Our sleep becomes disturbed when we are exposed to light. Even small amounts of light can cause hormone imbalance and throw off your biological clock.
This is so true for me. My room has to be totally dark. I can't even stand a glow from an alarm clock. My curtains block out any outside light.
Just last week my daughter commented on how well she slept in my room. When she got up in the morning, she was surprised that she slept so late and had such good sleep.
So if you are wondering why you can't sleep check out the article at Delicious Living. You will be surprised.

Hmmm…. This one is interesting. Maybe I need to close my blinds all the way. Of course, my bedroom is right next to the laundry room, and people in the apartment do laundry at the oddest of hours, so noise pollution may be a bigger factor.
