A new study has found that even if you’re not in an urban area, you can still get blue light exposure in your home, and even if your home is off the grid, you still could get blue lights in your car.
In a study published in the journal ACS Nano, researchers looked at the effects of blue light on a human’s circadian rhythms, and found that there were some environmental factors that were linked to increased exposure to blue light.
“It’s very likely that you’re exposed to a lot of blue in the day, and that’s reflected in the way you look, smell, and hear,” says lead author David J. Bock, a professor of electrical and computer engineering at the University of California, San Diego.
“You can actually see the circadian rhythm changes of your body that way.”
In the study, the researchers examined the relationship between exposure to various types of light in the home, including LED lights, compact fluorescent lamps, and white-light tubes.
In the first phase of the study they tested a sample of 12 volunteers, ranging in age from 20 to 50.
They found that the more blue light they were exposed to, the more likely they were to report experiencing symptoms of blue-induced health issues.
The researchers then examined the same individuals’ circadian rhythms to find how much blue light had an impact on their circadian rhythms.
“We looked at these data in detail,” Bock says.
“What we found is that a lot can happen in terms of the amount of light you get in the bedroom and in your house.
So even though we had some studies where you were exposed, you might still have some of your circadian rhythms not functioning correctly.”
In this study, a group of volunteers were randomly assigned to a light treatment group or a light control group.
Each group was assigned a total of four hours of daylight, and were also given a variety of health-related activities.
In one of the health-promoting activities, volunteers were given an LED light bulb and a white-screen screen.
Then, after the four-hour period was over, volunteers’ circadian rhythm was measured.
For each of the six hours that volunteers had been exposed to blue-light light, their circadian rhythm increased by a few percent.
Bocks says the results showed that exposure to LED light could actually make your circadian rhythm work differently.
“There’s no doubt that you can cause some effects,” Bocks tells Shots.
“But you can also be able to actually do things that would cause your circadian pattern to be different.”
Bock is also the author of a study that found that people with the highest blood pressure were most likely to report having health problems.
“That’s something we have seen in people that have high blood pressure,” he says.
Bocking says that while these findings may have implications for health, they may also apply to a broader range of things, including car emissions, air quality, and public health.
“So these studies show that we can have some impact on our health,” Bocking adds.
“And it’s not just about blue light in general.
There are many things that you could be exposed to that are causing these problems.”
The study was also able to track the impact of exposure to different types of lighting, as well as the effects that the environment had on the results.
In order to see if any of these effects could be predicted by exposure to a particular type of light, the team used a software program called Sarcophagus.
This tool helps to identify the types of lights that can influence circadian rhythms in different ways.
It then analyzes these types of blue lights and their effects on human circadian rhythms over a period of time, and produces a graph of how long exposure to each type of blue has a negative effect on the person’s circadian rhythm.
Belsky says the team plans to continue studying this and other blue light effects in the future.
“I think there’s going to be a lot more research in this area,” Belski says.
But Bock isn’t the only one to say that even though it’s been a while since we’ve had a study like this, it’s worth continuing to study this subject.
“These studies show some very interesting things,” Backs says.
