Light therapy can help you fight seasonal affective disorder (SAD) and the winter blues. SAD lamps are bright lights that can be used during the dark winter months to help keep up energy levels. Look for a SAD lamp that doesn't emit UV light and is at least 5,000 lux.
Sunrise alarm clocks simulate the dawn and increase intensity slowly to wake you up gradually. These lights are usually set like an alarm clock and some also have radios or nature sounds to help you wake up on time.
