Seasonal Affective Disorder, abbreviated accordingly as SAD, or better known as "winter depression," is described by the National Health Service (NHS) as a type of depression that comes and goes in a seasonal pattern. Symptoms include having a persistent low mood, irritability, despair and a general lack of energy. These symptoms are usually more apparent and more severe during the cold, dark winter days. One theory suggests that SAD might come from lack of exposure to sunlight, thereby affecting some parts of the brain responsible for controlling mood, appetite and sleep pattern. I remembered winter depression just recently when British Summer Time took 60 minutes back, and Ph is now plus 8 hours away. The gloom is coming, and as is heat tech undergarments and layers of clothing.
