Climate change: The impact on health

The consensus among scientists is that we are in an era of global heating and extreme weather events, primarily due to the devastating effects of human action on the environment. Why are researchers concerned, and what are the implications for health?

The Lancet Countdown team is a group of over 120 leading experts on climate, public health, economy, and political science — among others — who have committed to monitoring climate change, particularly its impact on global health.

Since 2015, the year of the Paris Agreement, the experts affiliated with the Lancet Countdown commission have published yearly reports assessing this situation and keeping signatory governments and decision-makers accountable for the commitments they have taken on following the Agreement.

The latest report, which appeared in The Lancet in October 2021, records “deepening inequities” across all regions as global heating remains a concern. The report discusses the impact of climate change in the context of the COVID-19 pandemic, and it emphasizes the concern caused by extreme heat events and related natural disasters that have occurred over the past 2 years.

Among the issues outlined in the Lancet Countdown report 2021, there is the impact of climate change on the livelihood of communities around the world, its direct and indirect effect on mental and physical health, and the way in which it contributes to the spread of infectious diseases.

These findings largely coincide with those outlined by another set of landmark reports on climate change — those of the Intergovernmental Panel on Climate Change (IPCC).

According to the IPCC 2022 reports, at present, extreme weather events caused by human action are surpassing the resilience of some ecological and human systems, sometimes with irreversible effects.

The reports show that weather extremes related to climate change have affected the productivity of various food sectors — including agricultural, forestry, and fishery sectors — around the world, thus exacerbating food insecurity.

They also emphasize the impact of climate change on mental health, and the ways in which it contributes to the spread of vector-borne communicable diseases.

In our latest installment of the In Conversation podcast, we discuss these aspects at length with two key experts. One of them is Prof. David Pencheon, honorary professor of health and sustainable development at the University of Exeter in the United Kingdom, and founder of the Sustainable Development Unit for National Health Services England and Public Health England.

Doctor fired from ER warns about impact of for-financial gain companies on U.S. health treatment

Clients searching for unexpected emergency treatment at the hectic Overland Park Regional Health-related Centre in Kansas around Kansas Metropolis, Missouri, did not know their safety was potentially at threat. But the medical director of the crisis division saw the hazard in 2012 and for many years urged his bosses to tackle it by introducing team associates. 

Then he was fired. 

What happened to the health care director, a former Army health care provider named Ray Brovont, isn’t an anomaly, some medical professionals say. It is a escalating problem as more emergency departments are staffed by for-earnings firms. A laser focus on earnings in health care can imperil patients, they say, but when some physicians have questioned the practices, they have been let go. Medical professionals who keep on being employed see that talking out can put their occupations on the line. 

Now, an believed 40-plus per cent of the country’s hospital crisis departments are overseen by for-profit overall health care staffing businesses owned by private fairness corporations, tutorial investigate, regulatory filings and interior paperwork clearly show. Two of the greatest, according to their websites and news releases, are Imagine Healthcare, owned by KKR, and TeamHealth, of the Blackstone Group. EmCare, the wellness care staffing corporation that managed Brovont, is aspect of Imagine.

Non-public equity corporations have taken around a broad swath of health treatment entities in current decades. They use substantial amounts of debt to obtain organizations, aiming to boost their revenue speedily so they can resell them at gains in a number of several years. 

There’s a explanation private equity firms have invested in businesses staffing clinic emergency departments, reported Richard M. Scheffler, a professor of well being economics and general public plan at the College of California, Berkeley.

“The revenue in the healthcare facility is in the ER,” he claimed. “It is the largest net generator and a big profit middle for nearly all hospitals.” The trouble, he explained, is that “ER doctors are becoming told how to practice medicine” by monetary supervisors.  

Brovont, the fired Overland Park unexpected emergency place medical professional, agreed.

“These directors who make these improvements and put into action these procedures really don’t come to feel the downstream outcomes of their plan alterations,” he said. “They glimpse at the end result, and the result is ‘Hey, we’re making cash.’”

Social media: Benefits vs. negative impact

Over the last 20 years, social media has risen from relative obscurity to become a fully accepted and integrated part of everyday life. However, despite social media’s ubiquity, the research on how it affects mental health remains inconclusive.

So far, most research investigating the effects of social media on mental health has focused on the potential negative aspects.

For instance, a 2019 study involving 6,595 teenagers from the United States concludes that those who spend more than 3 hours per day on social media may have a higher risk of mental health problems than those who do not.

But the degree to which social media actually harms mental health is debatable. A recent review, available as a preprint, found that most studies investigating the link between social media and mental health demonstrate “weak” or “inconsistent” associations.

Another review found that while there may be a small negative association between social media use and mental health, the link is complex and depends on exactly how researchers define mental health and social media use.

Meanwhile, other research suggests that social media may even benefit mental health, especially for people belonging to LGBTQIA+ communities and those living with mental health conditions.

These conflicting findings make it challenging to navigate the research investigating the effects of social media on mental health and how best to use social media. With this in mind, Medical News Today sought the input of seven psychology experts at the intersection of social media and mental health.

“One promising area of research is the role of online peer networks, where it appears that connecting online with others who share similar mental health challenges can offer important benefits for feeling less alone, learning coping skills, and being able to offer/receive emotional or informational support from others,” Dr. John Naslund, Ph.D., an instructor in global health and social medicine at Harvard Medical School, told MNT.

Dr. Niklas Johannes, a postdoctoral researcher in the Adolescent Well-Being in the Digital Age program at the University of Oxford in the United Kingdom, agreed that social media might be linked to some mental health benefits. However, he added that more research is necessary to confirm the direction in which this connection lies.

“There’s a lot of research out there that suggests social media are a

The scientists divided the international locations into a few teams according to 2019 Planet Bank Databases criteria. These were being significant-revenue nations (HIC), upper-center-earnings nations around the world (UMIC), and decrease-center-income nations around the world (LMIC). Their intent was to uncover if McDonald’s promotion techniques varied according to the monetary standing of a region.

The study confirmed that McDonald’s posted much more IG advertisements and applied selling price promotions, giveaways, and child-targeting advertising practices in LMICs. These advertisements are powerful the place the selling price of meals and drinks is vital in buyer purchasing conclusions.
