Typically in winter, many of us will experience seasonal affective disorder (SAD), a type of depression which usually affects us in the darker months.
A SAD lamp could help alleviate symptoms of the disorder, which include low mood, feelings of despair and lack of energy.
Many people have found that light therapy improves their mood considerably. SAD lamps come in various designs for you to place in your home, such as bedside table-style lamps or boxes you can place on your home-working desk.
The lights can also be used beyond winter. With the ongoing Covid-19 pandemic, we're all in need of a pick-me-up, whatever the season, and a SAD light could help bring you brighter days in the months to come.
A SAD lamp, light or light box uses light therapy to help improve your mood. They produce very bright lights to recreate the morning sunlight that you miss during the winter months.
The light produced is measured in lux and a good SAD lamp will offer a brightness of around 10,000 lux.
It's believed that SAD lamps encourage your brain to produce less melatonin, which makes you sleepy, while increasing the production of serotonin, which affects your mood.
