Scientists find link between pollution, poor mental health and heart disease

Scientists have discovered a link between pollution, stress and depression, which puts middle-aged adults living in areas with poor air quality at a higher risk of dying of heart disease.

Researchers in the US studied concentrations of tiny particles known as PM2.5 in the air across 3,000 counties, home to 315 million residents.

They found a relationship between the air people breathe, and their mental well-being and cardiovascular health.

“Our study indicates that the air we breathe affects our mental well-being, which in turn impacts heart health,” said study lead author Dr Shady Abohashem of the Harvard Medical School in Boston, the US.

Mental illness and air pollution have been linked to premature death in past studies.

The researchers wanted to know whether air pollution and poor mental health are interrelated and have a joint impact on death from cardiovascular disease.

They focused on particles less than 2.5 micrometres in diameter, which come from vehicle exhaust fumes, power plant combustion and burning wood, and present the highest health risk.

Exposure to PM2.5 was categorised as high or low, according to standards set by the World Health Organisation.

The researchers then gathered data on the average number of days that residents suffered from mental health issues such as stress, depression and emotional problems.

Each county was categorised into three groups based on the numbers.

The researchers found that counties in the top third reported the most days of poor mental health.

Counties with the most PM2.5 concentrations were 10 per cent more likely to report high levels of poor mental health days, compared to those with cleaner air.

The risk was “markedly” greater in counties with a high prevalence of minority groups or poverty, said researchers.

The link between poor mental health and premature death due to heart disease was strongest in counties with higher levels of air pollution.

In these counties, higher levels of poor mental health were associated with a three-fold increase in premature cardiovascular mortality, compared to areas with better well-being.

The researchers said a third of the pollution-related risk of premature cardiovascular deaths was explained by the increased burden of poor mental health.

“Our results reveal a dual threat from air pollution: it not only worsens mental health but also significantly amplifies the risk of heart-related deaths associated with poor mental health,” said Dr Abohashem.

“Public health strategies are urgently needed to address both air quality and mental wellbeing in order to preserve cardiovascular health.”

The findings will be presented on Friday at ESC Preventive Cardiology 2024 in Athens.

Recent research found that Google Street View could be used to predict coronary heart disease risk by analysing neighbourhood environments.

The study, published in European Heart Journal, monitored everyday surroundings, including the quality of roads, buildings and green spaces, and the role they play in determining heart health.

Researchers were able to track the link between these environmental elements, including the presence or absence of pollution, and the risk of coronary heart disease – a condition where the heart's arteries are blocked, limiting blood flow to the heart.

They found that these neighbourhood characteristics could account for 63 per cent of the differences in heart disease risk from one community to another.

What is a robo-adviser?

Robo-advisers use an online sign-up process to gauge an investor’s risk tolerance by feeding information such as their age, income, saving goals and investment history into an algorithm, which then assigns them an investment portfolio, ranging from more conservative to higher risk ones.

These portfolios are made up of exchange traded funds (ETFs) with exposure to indices such as US and global equities, fixed-income products like bonds, though exposure to real estate, commodity ETFs or gold is also possible.

Investing in ETFs allows robo-advisers to offer fees far lower than traditional investments, such as actively managed mutual funds bought through a bank or broker. Investors can buy ETFs directly via a brokerage, but with robo-advisers they benefit from investment portfolios matched to their risk tolerance as well as being user friendly.

Many robo-advisers charge what are called wrap fees, meaning there are no additional fees such as subscription or withdrawal fees, success fees or fees for rebalancing.

10 tips for entry-level job seekers
  • Have an up-to-date, professional LinkedIn profile. If you don’t have a LinkedIn account, set one up today. Avoid poor-quality profile pictures with distracting backgrounds. Include a professional summary and begin to grow your network.
  • Keep track of the job trends in your sector through the news. Apply for job alerts at your dream organisations and the types of jobs you want – LinkedIn uses AI to share similar relevant jobs based on your selections.
  • Double check that you’ve highlighted relevant skills on your resume and LinkedIn profile.
  • For most entry-level jobs, your resume will first be filtered by an applicant tracking system for keywords. Look closely at the description of the job you are applying for and mirror the language as much as possible (while being honest and accurate about your skills and experience).
  • Keep your CV professional and in a simple format – make sure you tailor your cover letter and application to the company and role.
  • Go online and look for details on job specifications for your target position. Make a list of skills required and set yourself some learning goals to tick off all the necessary skills one by one.
  • Don’t be afraid to reach outside your immediate friends and family to other acquaintances and let them know you are looking for new opportunities.
  • Make sure you’ve set your LinkedIn profile to signal that you are “open to opportunities”. Also be sure to use LinkedIn to search for people who are still actively hiring by searching for those that have the headline “I’m hiring” or “We’re hiring” in their profile.
  • Prepare for online interviews using mock interview tools. Even before landing interviews, it can be useful to start practising.
  • Be professional and patient. Always be professional with whoever you are interacting with throughout your search process, this will be remembered. You need to be patient, dedicated and not give up on your search. Candidates need to make sure they are following up appropriately for roles they have applied.

New UK refugee system

 

  • A new “core protection” for refugees moving from permanent to a more basic, temporary protection
  • Shortened leave to remain - refugees will receive 30 months instead of five years
  • A longer path to settlement with no indefinite settled status until a refugee has spent 20 years in Britain
  • To encourage refugees to integrate the government will encourage them to out of the core protection route wherever possible.
  • Under core protection there will be no automatic right to family reunion
  • Refugees will have a reduced right to public funds
