Is light therapy beneficial for seniors?

During certain times of the year, low levels of sunlight can negatively impact mood and energy levels. This light deficit can be especially harmful for individuals who are isolated or less independent. Light therapy can help alleviate these adverse effects when combined with healthy habits. Should seniors do light therapy? It might be worth a try.

The principle behind light therapy

Sunlight is vital for regulating the body’s biological clock. Particularly, it affects hormone secretion in the brain triggered by the daily rhythms of your body. In winter, low light levels can make it difficult for the brain to switch effectively between sleep and wake cycles. Light therapy involves exposing individuals to white light, which mimics the effects of natural sunlight.

Benefits for seniors

As you get older, your sleep patterns may become more easily disrupted. The negative effects of sleep deprivation on mood—such as irritability, sadness and difficulty concentrating—are well-documented. Light therapy can help mitigate these effects, especially for seniors dealing with cognitive disorders.

One study found that light therapy positively affected individuals with dementia. Regular exposure to white light improved sleep quality by 40 per cent, increased sleep duration by approximately two hours and reduced nighttime awakenings.

When integrated with a balanced lifestyle, light therapy can be beneficial. If you want to try it out, consult a healthcare professional for personalized advice.
