Sad light therapy lamps are useful and affordable tools for therapists, mental health professionals, and those who want to increase their natural energy levels. The lamps work by emitting a bright light that is specific to a particular wavelength. This wavelength can help boost the serotonin levels in the brain which can reduce the symptoms of depression, anxiety, and other mental health issues. The lamp itself is typically a small, boxy-looking device that can be easily moved around the house and plugged in. It generally has an adjustable brightness setting either through a knob or a remote control. The lamp is generally a form of fluorescent light and emits no more than 10,000 lux of illumination, which is equal to natural outdoor daylight. The effects of the light can become apparent within a few minutes. It is recommended that users spend anywhere from 30 to 90 minutes in front of the lamp to get the full benefit. Some users will find that a few minutes of use is enough to get them to feel more energized and positive. One of the most attractive features of a cheap sad light therapy lamp is that it can cost anywhere from just a few dollars up to hundreds of dollars. This makes it accessible to most people even with limited budgets and allows more people to benefit from its beneficial effects. In conclusion, cheap sad light therapy lamps are surprisingly affordable and can be found in a variety of forms to suit every budget. For those who suffer from seasonal affective disorder or depression, they are an effective way to help boost energy levels and reduce symptoms.
