(NaturalNews) Sometimes people feel worse when they're in the hospital, and now all the jokes about iffy hospital food or long waiting room times can be put to rest. Turns out, there's truth to mood changes and worsening health while in a hospital, and it may be due to something as mundane as the lighting.

A study reported in the Journal of Advanced Nursing found a link between extremely low hospital room lighting levels and changes in a patient's ability to sleep well, tolerate pain and be in a good mood (1).

Consider this: While a typical office emits about 500 lux (light emission measurement), and a sunny outdoor environment offers about 100,000 lux, it was discovered that, on average, hospital patients are exposed to approximately only 105 lux. That's nearly five times lower than the lighting many people face while at work and significantly less than the 4,000 lux that's required for proper, healthy sleep!


Light deprivation and the mood connectionResearchers said, "Low light exposure significantly predicted fatigue and total mood disturbance." Participants in the study with the lowest exposures to light during the day reported a more depressed mood and fatigue than those exposed to more light.

Light plays a role in activating areas of the brain that regulate mood and overall function. Therefore, it's no surprise that patients in the study were in more of a depressed state and experiencined increased fatigue, as well as a reduced threshold for pain. So serious is light (http://www.naturalnews.com/light.html) deprivation that many experts consider the malillumination-light link similar to the concept of inadequate nutrition leading to malnutrition: In both instances, without proper levels, it harms body and mind.

This is likely magnified during the winter months, when people are typically already experiencing mood-changes such as depression (http://www.naturalnews.com/depression.html) due to the darker season.

So vital is light, ideally natural sunlight, because it not only plays a role in boosting mood and improving sleep but can also help those with anorexia or epilepsy (2). Studies have even shown that not getting enough sunlight can lead to vitamin D deficiencies in pregnant women, in which case their children are more prone to develop cavities during their first dental exam (3).

The lighting levels are not nearly as depressing as what it costs to get care in a hospital.

I would say, it's not just the "low" lighting levels, it's the full-on artificial light courtesy of fluorescent tube fixtures. I've been in the architecture industry for almost 10 years, as a practicing architect since 2010, and lighting is a subject that most people simply don't understand. We had a project where we had spec'd normal tungsten filament fixtures, but the new energy codes outlawed them, so we went with compact fluorescent, which made the interior environment sickly and sterile. It totally effed up the interior ambiance, and we knew it was due to the lighting. Hospitals are notorious for providing the sterile sickly pale white light of fluorescent bulbs. This is not news for people who do this for a living, that it makes people uncomfortable, we know it and have been trying to bypass it for years now. Imagine how much more comfortable it would be with filament bulbs and natural light from fireplaces when you're trying to heal and get better. These things do matter and affect people.
