Lumie Reveals Light Levels Received In July Are As Low As A Winter's Day
Date:8/10/2009

feel tired and drowsy. During winter, especially when we’re indoors, the body receives inconsistent light cues - this change can cause our internal body clock to become misaligned; which means our sleep patterns, mood and behaviour alter as a result. For some, the disruption of the body clock can be so severe they feel considerably stressed and their day to day lives can become significantly disrupted; these people are suffering from SAD.

Another contributing factor thought to affect SAD is low serotonin levels (this is also common in people with depression). Serotonin is a neurotransmitter in the brain that responds to changing light levels; when it’s dark, grey and overcast outside, people can be left feeling low. Recent research also implies that lack of light exposure on short winter days can make proteins, which clear the brain of serotonin, more active.

The combination of the low light levels and miserable weather received in July has also prompted many to discuss the early onset of SAD symptoms online, through social networking sites, such as Twitter and the Lumie Forum. Lumie can also report that consumer sales figures for the month of July are up 37.5 per cent, compared to the same time last year.

One form of treatment that can be easily administered by people suffering from the early onset of SAD, is bright light therapy. Based on research, people need at least 2,500lux to combat the symptoms. Bright lights, such as the Lumie Pharos range emit 10,000lux at a practical distance, which is the same level of light produced on a bright spring morning and 20 times brighter than a well-lit office.

Bodyclock dawn simulators can also help treat milder forms of the condition, known as the winter blues. They provide a gentle awakening to light, rather than sound, and over a period of say 30 minutes create a gradual simulated sunrise, and this triggers a peaceful wake-up response that runs in tune with the b
