On walkable spaces for senior citizens
Here is a quick share of an article on walking and walkability, and the relation with dementia:
Steuteville, R. (March 10, 2025) “Living in a walkable place reduces dementia,” , https://www.cnu.org/publicsquare/2025/03/10/living-walkable-place-reduces-dementia [Last accessed: 3/29/2025]
To quote from the article:
“When we live in a walkable place, we move more, naturally. Unsurprisingly, exercise is linked to better cognitive health. Regular exercise increases memory, and boosts hippocampal volume by 2 percent.
Also, walkable neighborhoods are more stimulating. They are built on connected street networks, which give individuals more choices on how to get around and reward those choices with diverse physical paths linked to spatial memories. And they are mixed-use.
“Street layouts with better connectivity and walkability are associated with a reduced risk of cognitive impairment. Access to local amenities, such as food stores, community centers, and healthcare amenities, supports cognitive health,” the authors note.
Social connections also probably help. When you walk to a destination, you are more likely to have friendly interactions, which have been shown to reduce the risk of depression, and walkable places also boost the sense of community.”
As there are many senior citizens in our village, the topic is quite relevant. Most seniors probably won’t take a walk if they felt it was dangerous or risky even inside residential subdivisions. In our neighborhood, there are a few of them going around using their motorcycles or scooters. Most I see walking around perhaps for exercise or leisure rather than to go to a store or restaurant in the area. But increased traffic due to customers of restaurants that sprouted around the village has increased the risk for those who walk. Hopefully, the induced motor vehicle traffic generated by these establishments can be managed and regulated for the overall welfare of residents.

Article share: on how transportation impacts your health
I’ve written or shared articles here about transportation and health. I share another article concerning how transportation impacts our health. Here’s our first article share this August:
Harris, A. (August 1, 2024) “Getting there is half the battle: how transportation impacts your health,” The Flint Courier News, https://theflintcouriernews.com/getting-there-is-half-the-battle-how-transportation-impacts-your-health/ [Last accessed: 8/14/2024]
To quote from the article:
“In health, transportation is essential to how people access health care and maintain health,
whether it is getting to the doctor, picking up medication from the pharmacy, going to the
grocery store to maintain nutritional needs, or walking around their neighborhood to get more
exercise.”

On urban noise
We open February with an article share. The article is about noise in urban areas. Not surprisingly, most noise comes from transportation and the solutions mentioned in the article not only addresses transportation noise but at the same time addresses other concerns about transportation, including safety.
Durand-Wood, E. (January 25, 2024) “Why Are Cities So Noisy? And Can We Do Anything About It?“ Strong Towns, https://www.strongtowns.org/journal/2024/1/25/why-are-cities-so-noisy-and-can-we-do-anything-about-it [Last accessed: 2/2/2024]
To quote from the article:
“In 2011, the WHO set recommendations for daytime and nighttime environmental noise levels, and found the maximum safe noise level for daytime is 55db (somewhere between moderate rain and normal conversation) and at night, 40db (about the level of a quiet library). Beyond these levels, prolonged exposure to environmental noise has been shown to cause health problems, and not just hearing-related ones.”In 2011, the WHO set recommendations for daytime and nighttime environmental noise levels, and found the maximum safe noise level for daytime is 55db (somewhere between moderate rain and normal conversation) and at night, 40db (about the level of a quiet library). Beyond these levels, prolonged exposure to environmental noise has been shown to cause health problems, and not just hearing-related ones.
Until recently, most analysis related to urban noise has focused on noise as an annoyance or disruptor to humans. But with these new guidelines, there was an acknowledgement that too much environmental noise can actually have grave health consequences, noting that “at least one million healthy life years are lost every year from traffic-related noise in the western part of Europe.”
We now know that higher levels of environmental noise raise heart rate and blood pressure, cause harmful sleep interruptions, and are linked to cardiovascular disease, dementia, and cognitive impairment in children, among others. And as with environmental pollution, there are racial and socioeconomic disparities with noise pollution.
In a 2022 report, the United Nations identified urban noise pollution as a top environmental risk.”
Have you noticed how noisy it is in our cities? Many actually choose to live in the suburbs as the perception is its quieter especially during the night. The health risks due to noise are well-established as presented also in the article. However, there are ways to address this and reduce the noise, particularly the type attributed to transportation and traffic.

On the benefits of walkable communities to pregnant women
I break the series on MCIA Terminal 1 to share this interesting article relating walkable communities to healthier pregnancies:
To quote from the article:
“The study, published in the journal of Economics and Human Biology, found that expectant mothers living in walkable counties tend to engage in more walking and exercise and have fewer issues with premature births, low birth weight, gestational diabetes and hypertension. Walking is often recommended as a safer, more moderate activity for pregnant women, so the authors reasoned that living in a more walkable area could have health benefits for them.”
If you’re interested in the details of the study referred to in the article, here is the link to the paper entitled “You’ll never walk alone – the effects of walkability on pregnancy behaviors and outcomes” in the journal Economics & Human Biology:

On one’s exposure to noise
Here is another article on noise, relating about how it affects our health (e.g., “noise can damage your heart as well as your hearing”). The article also includes reference to an app developed by the US National Institute for Occupational Safety and Health (NIOSH) – a sound level meter iOS app that utilizes sound energy, and has its accuracy verified in an acoustics lab.
To quote from the article something related to transport and traffic:
“As a general rule of thumb, the World Health Organization considers average road traffic noise levels above 53 decibels and average aircraft noise levels above 45 dB to be associated with adverse health outcomes, though their metrics are weighted slightly differently than the average on your screen.
Nighttime noise is considered particularly harmful because it can fragment your sleep and prompt a stress response, even if you don’t remember waking up. The W.H.O. has long recommended less than 30 dB of nighttime noise inside your bedroom for high-quality sleep.”
We tend to dismiss or take for granted the noise from transport and traffic. While it seems that it does not have an effect on our health and well-being, it will eventually catch up with us and cost us health-wise. I have downloaded and installed the NIOSH app on my phone and occasionally monitor the noise around me whether I am at home or at the office. It can get pretty loud during my commutes and I drive so am curious how loud it can be for those taking public transportation. I have experienced riding in jeepneys blaring loud music. A daily dose of that for long periods each way of the commute will surely affect one’s hearing and overall health. Exposure, after all, isn’t just about the intensity of the noise but how long you experience or endure it.

On noise and how it affects your health
I am sharing this article on noise that was recently published in The New York Times:
Baumgaertner, E., et al (June 9, 2023) “Noise Could Take Years Off Your Life. Here’s How,” The New York Times, https://www.nytimes.com/interactive/2023/06/09/health/noise-exposure-health-impacts.html?smid=url-share [Last accessed: 6/13/2023]
To quote from the article:
“European countries have far outpaced the rest of the world in regulating noise. The European Union requires member nations to monitor and assess sound levels across regions and to produce new action plans every five years to address communities at greatest risk. The E.U. now mandates quiet brake locks on rail freight fleets and noise labels on outdoor power equipment; it also requires noise reduction in car manufacturing and mitigation efforts at airports.
Individual cities and countries have taken additional measures. Paris has installed noise cameras that measure the sound level of vehicles and fine drivers who exceed them. Berlin has used new bike lanes to reduce the flow of engine-powered vehicles and move the source of the noise to the center of the road, away from houses. Switzerland has introduced national “quiet hours” — overnight, one midday hour on weekdays, and all day on Sundays.
While scientists say it’s too soon to make a prediction about the effects of these policies on cardiovascular health, several European countries have reported tens of thousands fewer residents exposed to major sources of noise.
Like many health issues, protection against noise would be economically advantageous. Economists who analyzed health care spending and productivity loss because of heart disease and hypertension have argued that a 5 dB reduction in U.S. noise could result in an annual benefit of $3.9 billion.”
Not everyone is aware of how noise may affect our health. Most of us are exposed to noise of different levels and lengths of time (i.e., duration). We probably take for granted, for example, the noises we hear during our commutes or perhaps the noises in our workplaces. These actually take a toll not just on our hearing (e.g., long time factory workers likely have hearing problems after they retire) but other aspects of our health as well. Long commutes inside jeepneys blaring music can do damage to your health. Noise from busy streets will cause damage to the health of those residing along these streets. Are we doing anything to mitigate such noise in the Philippines?

Covid test kits at the airport
Despite the relaxed stance on COVID-19, the virus is still very much around and evolving or mutating. While airports in the Philippines are lax about the wearing of masks, airlines require masks for passengers on flights. I’m not sure how effective as a preventive measure this is since most people at airports don’t wear masks and there is nothing that will allow for contact tracing anymore.
Meanwhile, COVID-19 test kits vending machines are now common at airports. I guess aside from being a reminder of the pandemic, it is also a convenience for people who want to check, quickly though not so accurately, if they are positive for the virus.

On air quality in subways
I saw this article on Wired and immediately read it as the topic to me was interesting. I have been using when I lived in Japan in the 1990s and in Singapore in 2010-2o12. I have used the transit system in many other cities including in the US and Europe. And so the topic of air quality in subways (particularly the stations and inside the trains) got my attention. I guess this is not entirely an issue for ground-level and overhead systems like what most of Lines 1, 2 and 3 and the PNR are. Only Line 2 has one underground station (Katipunan Station) and perhaps has that issue. Here is the article about the air in subways:
Baraniuk (April 24, 2023) “The Filthy Truth About Subway Air,” Wired, https://www.wired.com/story/subway-air-health/ [Last accessed: 4/25/2023]
To quote from the article:
“The big unknown is whether all of this particulate matter is actually causing health problems for people. Millions of commuters use metro systems, in many cases for multiple hours a day, five days a week, for years on end. And thousands of transport workers spend even longer in the tunnels. But there are no widespread signs of severe or acute health problems among these populations, even if pollution levels in subways exceed recommended limits. Could there be more subtle, chronic effects, however—impacts on lung, brain, or heart function?”
Indeed, metros or subway systems have been operating for over a century and so far there is limited that we know about the health risks concerning their use by passengers. But this is something to keep in mind as the Philippines builds its first subway line in Metro Manila. The depots and the situation of workers thought may be a different matter. I recall one of my colleagues at the university doing a quick study of the Line 3 depot, which is underground (i.e., underneath the Trinoma Mall), and measurements showed the air quality to be quite bad. Imagine working there and being exposed to that everyday. Those conditions merit further study but require immediate action to improve working conditions considering the impact to health.

Noise, air pollution and your health
Here is another quick share of an article relating transportation and health:
Hunter, M. (March 27, 2023) “Road Noise Might Be One Reason Why Your Blood Pressure is High,” Medium.com, https://medium.com/beingwell/road-noise-might-be-one-reason-your-blood-pressure-is-high-5f6c7bd69ad8 [Last accessed: 3/29/2023]
To quote from the article:
“After a median of 8.1 years, the researchers discovered a dose-response relationship: The higher the noise exposure, the greater the risk of having a diagnosis of hypertension.
For every 10 decibel increase (in average 24-hour road traffic noise level), there was a 1.07 times rise in the chances of having high blood pressure. The researchers adjusted the data for fine particles (PM2.5) and nitrogen dioxide (NO2) exposure.
Exposure to air pollution and traffic noise exposure led to the highest high blood pressure risk.”
Both air pollution and noise are mentioned as issues to be addressed by implementing programs for sustainable transport. Sustainable transport includes low carbon transport as well as the reduction of noise generated by traffic.

On the air that you breathe when inside aircraft
I am sharing a different kind of article this time. It is still on transportation but more health-related in the sense that the article’s topic is about the air passengers breathe when inside a plane. This is very relevant as we continue to grapple with COVID-19 and other diseases such as influenza, while also trying to get back to our normal activities including traveling whether for family affairs, work, recreation or other reasons.
McGee, W.J. (September 20, 2022) “How clean is the air on planes?” Condé Nast Traveler, https://www.cntraveler.com/story/how-clean-and-safe-is-a-planes-cabin-air?utm_source=nl&utm_brand=spotlight-nl&utm_campaign=aud-dev&utm_mailing=thematic_spotlight_092122_2&utm_medium=email&bxid=5bd6761b3f92a41245dde413&cndid=37243643&hasha=cf6c402001bc473063a8744033fe9be3&hashb=ec2bb753c2e6299f5107823241955221da67bd1f&hashc=09f65c608bfb62050199733de500e3cd82827631b36d537ce8386d41a3bd1ff7&esrc=FYL_SEG_APR18&sourcecode=thematic_spotlight&utm_term=Thematic_Spotlight [Last accessed: 9/21/2022]
Obviously, there are concerns about the air inside the cabin. But there are other items that one needs to be mindful of if you are truly concerned with the risk of infection.
To quote from the article:
“But some experts have expressed more doubt about the ability to completely scrub the air for zero chance of spreading flu and COVID. “Transmission of infection may occur between passengers who are seated in the same area of an aircraft, usually as a result of the infected individual coughing or sneezing or by touch,” WHO warns. Cabin crew members agree with this assessment. “It’s naive to think an airline can protect passengers 100 percent because you’re in an enclosed space for however long the flight is,…””
The article also provides the following recommendations to travelers (quoted directly from the article and highlights mine):
- If you’re concerned about aircraft cleanliness, try booking the earliest flight possible that day, as most airlines do a deep-clean each night. And if your itinerary allows it, consider nonstops rather than connecting flights, to limit your exposure to multiple dirty cabins.
- Wipe down your airline seat and surrounding area with a sanitizing wipe to kill any lingering flu virus; pack an alcohol-based hand sanitizer and wash your hands often.
- The CDC recommends that most travelers get a flu vaccine in September or October; it also advises to get up-to-date with your COVID vaccines and boosters before any travel.
- Practice social distancing throughout your journey—at check-in, security screening, boarding, baggage claim, etc. Select seats apart from other passengers (often in the rear) and ask to be moved if possible.
- Although there is no longer a mask mandate for air travel in the U.S., the CDC still advises travelers ages 2 years and older to opt to wear a face mask in indoor areas of public transportation—such as airplanes, trains, buses, ferries—and in transportation hubs like airports.
There seems so many of what are being termed as revenge travel these days. Many people were not able to travel particularly for family (visits, homecomings) or recreation (vacations) the past 2 years. They are now traveling again as more countries open up for tourism and more people have been vaccinated or gained immunity from the virus. The recommendations above should be heeded as there’s really nothing to lose if we follow them and particularly continue good practices to avoid infection.
