Study Confirms What We Already Knew: Living Near Water Can Reduce Stress

Beachfront property is considered the pinnacle of real estate for the views, the lifestyle, and, of course, the shoreline access. Everyone knows that being on the water makes us feel good, but now there's scientific proof: a new study confirms that living near a body of water improves wellbeing, even for city dwellers. The report was published in the journal Health & Place.

Scientific interest in so-called "blue" and "green" spaces is relatively recent, but cultural awareness of nature’s therapeutic power is quite old. Poets, Christian mystics, and nature-worshiping pagans alike all celebrated the power of the trees and tides. These days, we’re just getting good at quantifying it. 

Just a few weeks ago, for example, researchers published a study showing that living near lots of trees or other vegetation can actually extend a woman’s lifespan. The authors of that study cited three potential reasons green spaces might improve health: they provide inviting places to exercise, create opportunities to socialize, and they reduce stress.

The authors of the new paper believed that the same was true of blue spaces. They were especially interested in stress reduction, and whether blue and green spaces’ purported ability to calm would hold up in crowded city environments—specifically the capital city of Wellington, New Zealand. With nearly 500,000 citizens, the Wellington area is home to 10.6 percent of New Zealand’s entire population. 

The researchers pulled topographic information from national databases, mapping any forested areas, parks, and coastlines that would be visible to residents. They then looked to the 2011/12 New Zealand Health Survey (NZHS), which included questions on health, lifestyle, doctor visits, socioeconomic status, chronic medical issues, and mental wellbeing. Of the adults who took the survey, 442 were Wellington residents. 

The health and topographic data were then combined and analyzed. Some of the results were predictable, but others came as something of a surprise. "Increased views of blue space is significantly associated with lower levels of psychological distress," Michigan State University health geographer Amber L. Pearson said in a press statement. "However, we did not find that with green space."

Was it a money thing? After all, people in higher socioeconomic tiers tend to have better access to green and blue spaces, as well as medical care. But even after controlling for variables like sex, wealth, age, and local crime rates, their findings held true: being able to see the water was associated with better mental health for just about everyone. 

To ensure that their tests were accurate, the researchers decided to measure blue space visibility with a totally unrelated factor: toothlessness. If they found a significant  relationship between seeing water and missing teeth, they’d know something was wrong. But the relationship wasn’t there. 

Why would water help, but not trees? Pearson admits those particular results may have something to do with their study design. "It could be because the blue space was all natural, while the green space included human-made areas, such as sports fields and playgrounds, as well as natural areas such as native forests," Pearson said. "Perhaps if we only looked at native forests we might find something different."

The Very Disgusting Reason You Should Always Wash New Clothes Before Wearing Them

It’s sometimes assumed that clothing with a price tag still dangling from the sleeve can skip an initial wash. Someone else may have tried it on, sure, but they didn’t run a marathon in it. Why not just throw it in the closet as soon as you get home?

One big reason: lice. As The Independent reports, Donald Belsito, a professor of dermatology at Columbia University Medical Center, told NBC's Today show recently that clothing fresh off store racks can harbor infestations of lice, scabies, or fungus.

You might be familiar with head lice as the dreaded insects that occupy the scalp and give school health monitors cause for concern. Head lice can be transmitted via clothing and other fabrics, and anyone who tried on a shirt or dress before you did can be a carrier. While they only live for one or two days without a blood meal, that’s still enough time to cause problems if something is being tried on frequently.

Scabies is far more insidious. The mites are too small to see, but the allergic reaction they cause by burrowing into your skin to lay eggs will be obvious.

Both scabies and lice can be treated with topical solutions, but it’s better to kill them by washing new clothes in hot water. A good soak can also get rid of formaldehyde, a common chemical used in fabrics to help ward off mold in case stock gets wet in transit. Formaldehyde can cause allergic skin reactions. For all of these reasons, it’s best to hit the washing machine before those new pants ever hit your hanger.

How Promoting Handwashing Got One 19th Century Doctor Institutionalized

Regardless of how often we actually do it, it's common knowledge that washing our hands before eating, after coughing, and after using the bathroom is good for us. But the connection between handwashing and health wasn't always accepted as fact. As Danielle Bainbridge explains in the PBS web series Origin of Everything, the first doctor to campaign for cleanliness in hospitals was not only shunned by other medical professionals, but ended up in an insane asylum.

Prior to the 19th century, handwashing primarily existed in the context of religious ceremonies and practices. It plays a role in Christianity, Islam, Judaism, Sikhism, and Buddhism in some form or another. But washing up to stop the spread of disease wasn't really a thing for most of history. People weren't aware of germs, so instead of microbes, they blamed illness on everything from demons to bad air.

Then, in 1846, a Hungarian doctor named Ignaz Semmelweis made a breakthrough observation. He noticed that women giving birth with the help of midwives were less likely to die than those treated by doctors. He determined that because doctors were also performing autopsies on victims of puerperal fever (a bacterial infection also known as childbed fever), they were somehow spreading the disease to their other patients. Semmelweis started promoting handwashing and instrument sterilization in his clinic, and the spread of puerperal fever dropped as a result.

Despite the evidence to support his theory, his peers in the medical community weren't keen on the idea of blaming patient deaths on doctors. Partly due to his commitment to the controversial theory, Semmelweis was shunned from his field. He suffered a mental breakdown and ended up in a mental hospital, where he died a few weeks later.

Germ theory did eventually become more mainstream as the century progressed, and washing hands as a way to kill unseen pathogens started gaining popularity. Even so, it wasn't until the 1980s that the CDC released the first official guidelines instructing people on best handwashing practices.

If this story suddenly has you in the mood to practice good hygiene, here's the best way to wash your hands, according to experts.
