Circadian Data

    How Circadian Rhythm effects Patient Health.


Sunshine and Daylight is our circadian Light source. Correct exposure  stimulates our Circadian Rhythm, which regulates the  bodily functions. The main bodily function of Daylight involveour sleeping and waking cycle. The human body needs circadian Light source to assist the human body to  function properly.

Buildings & Light

It is important to understand where and even if, the Sunshine and Daylight is penetrating the building. This circadian source of light is particularly important for the quality of patients’ lives in Hospitals and Nursing homes. 

Window Limitations

Sunlight will  only penetrate a building, as much as the windows will allow and this may be just a couple metres inside. However, on the other hand  when you have bright sunny days, it may be necessary to close blinds or curtains to prevent glare . 

This can result in patients not   getting enough of the  circadian effect to help in regulating their bodily functions. For patients in Hospitals and Nursing Homes, the correct level of daylight will greatly enhance the quality of patients’ lives.

Correct Levels of Light

With the Ewindow,  patients will get their circadian light source and the correct level of light for each time of day. This is excellent, not only for individuals eye comfort but also for their psychological well-being, because it encourages the secretion of the Serotonin Hormone in our brain. Incorrect levels of  lighting is one of the reasons why ‘Sun Downing’ in Alzheimer’s Patients may occur.

Simulates from Dawn to Dusk

The Ewindow simulates daylight from dawn to dusk. There have been many studies completed on Alzheimer’s Disease and related Dementia (See File ARDA Patients) sufferers where Dawn to Dusk Simulation for the patients has been proven to improve their sleeping patterns, reduce their evening time agitation from the Sun Downing effect and improve the patients daytime wakefulness. Another reason why Sun Downing occurs is the disturbance to the 24-hour ‘body clock’.

Proven to help Alzheimers & Dementia Patients

  • The high quality of light from the Ewindow is another reason why it can   benefit   Alzheimer’s Disease and Related Dementia patients. Typical Lux readings for the single unit of 600 x 600mm is 3000 Lux and the larger double unit provides 4500 lux. Illuminance is the measure of the amount of light received on the surface. It is typically expressed in Lux ( lm/m2)

  • In studies of Alzheimers and Related Dementia, Findings  show that  bright light therapy, with exposure to  at least 1,000 lux for two hours each morning, has a variety of benefits on patients improving their night time sleep, and increasing their daytime alertness. It also reduces their evening agitation resulting in better rest and activity patterns overall. The Ewindow can provide up to 10,000 Lux at it’s maximum ‘Noon’ setting.
