It’s not unusual for beachgoers to do their best to avoid touching the beach with their feet, but if you’re on a beautiful, sunny day, the beach may be less pleasant.
And that’s where your knees come in.
According to a study published in the journal PLOS ONE, the presence of a knee can make the sun shine a little brighter, especially on the east coast.
The researchers analyzed data from 4,000 beachgoers, looking for the presence and location of knee joints, and found that it was strongly correlated with a pleasant beach environment.
The presence of knees is also correlated with lower incidence of skin cancer and cardiovascular disease, as well as lower rates of skin irritation and skin allergies, the researchers say.
“We were surprised by this association,” says senior author Shana Gee, a research scientist in the Department of Psychology at the University of Arizona.
“I think it’s interesting to think about the way in which we humans interact with the world around us.”
The researchers found that knee joints are most commonly found along the east and south coasts of the United States, but also along the eastern seaboard, and along the Gulf Coast of Florida.
According to Gee and her colleagues, knee joints can be particularly problematic on the coasts because of the high risk of sunburns and other skin diseases.
In fact, knee pain was found to be the third leading cause of skin-related death among beachgoers.
Gee says that it’s not surprising that people on the beaches should avoid touching themselves while walking on the beach, because there are many types of skin conditions that can lead to skin cancer, including eczema and psoriasis.
The findings also show that people are more likely to touch their knees while standing, because they are easier to reach and they can have a greater distance to reach.
There are other factors that could contribute to knee pain on the East Coast, Gee adds, including weather conditions, the length of time you spend walking on beach, and the fact that people often don’t sit or stand while enjoying the beach.
Still, there is one thing that is for sure: if you do choose to do your best to not touch your knees on the sandy shores of New York City, there’s a chance you may be exposing yourself to more skin irritation than you bargained for.
So if you want to avoid getting sunburned while you’re walking on a beach, there are things you can do to keep your knees in check.
