Does Light Therapy Help Dementia?

Insomnia is one of the worst symptoms that people with dementia struggle with. This symptom comes from the disrupted circadian rhythm that this condition tends to cause.

This rhythm keeps your body in balance, meaning it acts like a biological clock that helps you sleep when it’s night and wake up when it’s the day, among many other things. So, what happens when the circadian rhythm is disrupted? People need to sleep during the day and stay awake at night.

When people were introduced to light therapy, they reported significant improvements in their sleeping, meaning they did not experience as many sleeping disturbances as before this therapy. 

Therefore, to answer the question, does light therapy help dementia? Yes, it may. Based on the best research done so far, it is clear that light therapy might have positive effects in improving insomnia in people with dementia, meaning improving their overall well-being.

However, as not everything is black and white, there are some other essential things you need to know regarding dementia and light therapy, such as how to make the light therapy as efficient as possible, so be sure to keep reading.

What does the research show?

One of the largest and most well-conducted research reviews found that introducing light therapy to people who have dementia might result in regulating the circadian system, meaning the patients’ daytime sleeping is decreased and their night-time sleeping is increased.

That being said, much more thorough research is needed on this topic, but the results are quite promising so far. People have reported improving their symptoms after only a few light therapies.

As light therapy is gaining popularity for treating and helping various conditions, scientists do better and improved research all the time to increase the efficiency of this therapy even more.

More research is needed regarding light therapy and dementia, but from what we can see until now, the results are positively promising.

How to Administer Light Therapy

One of the greatest features of light therapy is that besides the therapy facilities, it can also be administered at home. The process is extremely easy, and many benefits come from this. 

First, by administering the light therapy at home, you will feel much more relaxed from the start than going to the hospital or other facilities that provide this therapy. 

Second, besides the benefits of the light therapy itself, which we will look at in a moment, you may work on your discipline by being calm during the administration, meaning your anxious or angry behavior should also significantly improve.

Third, the lightbox you will need for the therapy will cost you much cheaper than taking the patient elsewhere, so you might save a significant amount of money that could be distributed to other medications, vitamins, supplements, etc.

Although many more benefits may come from light therapy, these three are the most important ones with the most significance for the dementia patient.

Consult with your doctor

The first and most important thing you will need to do before you start light therapy is to talk to a professional. The best will be if you talk to your doctor, who monitors your condition and symptoms closely. 

As a few minor side-effects can occur from this therapy, you will need to provide information, such as whether there is a family history of macular degeneration because the strong light can negatively affect the patient’s eyesight

Second, you must disclose the medications because some can cause photosensitivity. Also, you must be aware that mild headaches might occur.

Get the lightbox

Before you get a lightbox, you need to ensure that it produces 10,000 lux and look for a UV-free light. You do not want to expose the patient to ultraviolet light.

Administer the therapy

While talking to your doctor, they will advise you on the optimal amount of how long the sessions need to last. However, the average amount is 30 minutes a day, and the lamp should be 2 feet away from you. Also, make sure that the light does not go directly to your eyes.

Do not skip sessions

Skipping sessions will not bring you the wanted results and may not have the full effect this therapy provides.

Therefore, it is of essential importance to administer light therapy regularly, a few times a week, for a prolonged period. You should consult with a professional about it.
