Hospitals can be pretty overwhelming. Sometimes you may feel like you need a map to find your way around the maze, not to mention a trusty guide to get you to the department or health professional that could actually help you overcome illness. In addition, being hospitalized often means being deprived of fresh air & sunlight. Could that be a mistake for proper healing?
At The People’s Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

Striving for Person-Centered Care
Wouldn’t it be great if healthcare facilities were specifically designed around the individuals they are supposed to serve? Fifty years ago, a group of physicians and former patients started Planetree to do exactly that. At first, Planetree provided information at a time when patients were rarely told what was wrong or how it could be addressed. There was also a Planetree ward in a hospital in the Bay Area that operated on principles of transparency and person-centered care.
Over the next several decades, Planetree developed as a network of more than 300 health care facilities in 30 countries that strive to provide a home-like environment for healing. The main value is person-centered care, in which they strive to treat the whole person as well as that individual’s family or significant others. We invited Planetree President Michael Giuliano to tell us about it. He mentioned that one feature is getting your care summary in real time, so you can ask questions and correct errors before you leave the clinic or office.
Fresh Air & Sunlight Built In
One of the things that sets a Planetree hospital apart from other facilities is the way the values are visible in the architecture. Planetree planners put a premium on access to nature and outdoor space, though of course each facility does it a bit differently, according to its own plan. Rooms are set up so that people have access to fresh air & sunlight. That makes them feel more comfortable, certainly. Might it also promote healing?
How Do Fresh Air & Sunlight Promote Healing?
More than 150 years ago, Florence Nightingale set standards based on what she observed of soldiers healing from battle wounds and horrible infections during the Crimean War. This was, of course, before the development of antibiotics, so nursing care was paramount. Nurse Nightingale insisted on the primacy of fresh air & sunlight for her patients. Was this just a quaint old-fashioned idea, or is there modern scientific support?
The Power of Near-Infrared
For more information on the science of fresh air & sunlight (yes, there is science), we turn to Dr. Roger Seheult of MedCram.com. https://www.medcram.com/ He began by describing the brand new Footscray Hospital in West Melbourne. The design is something of a modern take on Florence Nightingale’s hospital plan, since the architects figured out how to get natural light and real ventilation in every room. They prioritized fresh air & sunlight in this $1.5 billion hospital because of their healing properties. People exposed to sunlight leave the hospital sooner because they recover more quickly. So the patient gets better and goes home faster, the hospital has a better bottom line and the insurance company pays less. Everybody wins!
Probably a good part of the credit goes to near-infrared light. We can’t see it, but it penetrates our bodies and they react. Exposure to near-infrared at 850 nanometers improves mitochondrial function. You could get this from a device, but it is cheaper and arguably more pleasant simply to go outside and allow sunlight to fall on your skin soon after sunrise (or before 10 am) or just before sunset (probably after 4 pm).
An Amazing Story About Fresh Air & Sunlight
We’d be tempted to call this an unbelievable story, but Dr. Seheult provided all the details and checked the medical records himself, so we believe it. He told us about a 15-year-old boy with a serious blood cancer, acute lymphoblastic leukemia, ALL. This type of cancer undermines the immune response, and this young man had come down with a terrible fungal infection, mucormycosis. The fungus did not respond to medication, and it rampaged through his left lung. Ultimately, his doctors proposed removing the lung as a last-ditch method of controlling the infection.
Unfortunately, when they found that the fungus had invaded his right lung, they were out of options. They figured he probably couldn’t survive much more than two days, so they asked him his last wishes. All he wanted was to go outside; at this point, he’d been cooped up in the hospital for two months. They fixed up a wheelchair to hold all his drips and took him outside. The next day, they did it again. The youth didn’t die as expected. Instead, he recovered completely, over time. We can’t put sunlight in a bottle, but perhaps oncologists and other doctors should consider writing prescriptions to cover it.
