NON-PHARMACEUTICAL INTERVENTION

Biodynamic lighting has a positive effect on emotional and physical wellbeing

Research studies have shown that biodynamic lighting has a positive effect on emotional and physical well-being.

If a person with dementia feels more relaxed and more comfortable in their surroundings under biodynamic lighting and are able to participate more in daily activities (5), this in turn can help to make the work of the caregiver more effective and efficient. It can enhance their work environment, increase their productivity and alertness, support their internal clock, counteracts insomnia, reduces eye strain and fatigue which is often a result of poor lighting.

Biodynamic lighting can enable people with dementia to stay longer in their own familiar home environment by utilising the therapeutic benefits of biodynamic light as a non-pharmacological solution (1, 2, 3).

  • Lighting research has shown that biodynamic light has a positive effect on biological, physiological and psychological well-being and health.
  • It can support and regulate the biological clock, known as the circadian rhythm to a 24-hour sleep/wake cycle in older adults and people with dementia.
  • A restored circadian rhythm can enable older adults to be more active throughout the day, provides them with more energy to engage with activities such as gardening, spending time with family and friends or simply relaxing and reading.
  • Sleep pattern becomes uninterrupted for longer periods which allows for a more restful night sleep. As a result the administration of sleep-inducing drugs could even be reduced in some cases.
  • Biodynamic lighting can enhance their surrounding environment, improving their visual acuity and spatial awareness so that they move safely without the risk of falls (4, 5, 6, 7, 8).
  • It has been shown to enhance better recognition of colour and objects within their environment, and highlights the facial expressions of the people who cares for them (9, 10).
  • Biodynamic lighting creates an opportunity for people with dementia to live independently for longer in their own home environment, it enhances their quality of life and those of their families.
