Do you feel stressed? Are you tossing and turning? It doesn’t take Dr. Phil to know that depression can affect anyone and can impact on everything you do, including sleep. However, what is a little surprising is that, according to a recent study, depression may be both a cause and a symptom of poor sleeping patterns. Recently, it was discovered that mice continuously exposed to light over a 24-hour appeared more depressed than mice observed in a normal dark-light cycle. For ideal sleeping conditions and to minimize the possibility of light-induced depression, turn out the lights and close the drapes to ensure your room is as dark as possible.
