Green spaces – trees, shrubs and grasses – can improve air quality and may lower heart disease deaths, according to preliminary research to be presented at the American Heart Association’s Scientific Sessions 2020.

“We found that both increased greenness and increased air quality were associated with fewer deaths from heart disease,” said William Aitken, M.D., a cardiology fellow with the University of Miami Miller School of Medicine and UM/Jackson Memorial Hospital in Miami, Florida.

Greenness is a measure of vegetative presence (trees, shrubs, grass) often assessed by NASA imaging of the Earth and other methods. Here, researchers used the Normalized Difference Vegetative Index (NDVI), which measures wavelengths of visible and near-infrared sunlight reflected from the Earth’s surface via NASA satellite imagery. A higher index corresponds to more healthy vegetation, as chlorophyll typically absorbs visible light and reflects near-infrared light.

In this cross-sectional study conducted using national air quality, greenness, CVD and census data from 2014-2015, researchers measured greenness by county across the United States and compared it to national disease death rates from the Centers for Disease Control and Prevention’s Interactive Atlas of Heart Disease. They also overlaid data from the Environmental Protection Agency’s air quality measurements of particulate matter for each county and the Census Bureau’s information on age, race, education and income by county.

The analysis found:

  • For every 0.10 unit increase in greenness, deaths from heart diseases decreased by 13 deaths per 100,000 adults. Greenness (NDVI) values ranged from 0.00 – 0.80.
  • For every 1 microgram increase in particulate matter per cubic meter of air, death from heart disease increased by roughly 39 deaths per 100,000 adults.

“We found that areas with better air quality have higher greenness, and that having higher greenness measures, in turn, is related to having a lower rate of deaths from heart disease,” said Aitken, who collaborated on the research with University of Miami public health scientists.

“Given the potential cardiovascular benefits of higher greenness measures, it’s important that dialogue about improved health and quality of life include environmental policies that support increasing greenness. Policymakers should support greenness through efforts that promote environmental justice through equitable access to green spaces, clean air and clean water, as well as minimizing exposure to environmental hazards,” he added.

The researchers hope their results encourage clinical trials using built environment interventions (e.g., tree planting to increase vegetative presence and greenness) to improve cardiovascular health. “We will be performing a longitudinal study in Miami to assess if changes in neighborhood greenness over time are associated with changes in cardiovascular disease,” Aitken said.

The main limitations of this study include that it was cross-sectional and used a total of combined cardiovascular disease death rates.

Men with sensory loss are more likely to be obese

The association between physical activity and obesity was higher in men with hearing loss, who were 2.319 times more likely to be obese than women who reported difficulty hearing. Obesity in those with sight loss was 1.556 times higher in inactive men than women.

Men who suffer sensory loss, particularly hearing loss, are more likely to be physically inactive and obese than women, according to a new study published in the European Journal of Public Health.

Researchers analysed data from more than 23,000 Spanish adults, and examined associations with physical inactivity and obesity in people with vision and hearing loss, and explored differences between men and women.

Results suggest inactive people with hearing loss were 1.78 times more likely to be obese compared to those who did not have any hearing loss. In people who had difficulty seeing, the odds ratio is slightly smaller, with a likelihood of obesity being 1.375 times higher than those who did not report vision loss.

The association between physical activity and obesity was higher in men with hearing loss, who were 2.319 times more likely to be obese than women who reported difficulty hearing. Obesity in those with sight loss was 1.556 times higher in inactive men than women.

Those with combined seeing and hearing difficulties had the highest prevalence of physical inactivity (44.8%) and obesity (26.1%). Analysis showed a significant association between physical inactivity and obesity in men with vision or hearing loss, but not in women.

Around 62% of adults in Spain are overweight, with 26% reporting as obese. In the UK, the figures are broadly similar at around 64% and 28% respectively, suggesting strong similarities between the countries.

A total of 11.04% of the people surveyed self-reported vision loss, 6.96% reported hearing loss, and 3.93% reported suffering both vision and hearing loss.

Lead author Professor Shahina Pardhan, Director of the Vision and Eye Research Institute at Anglia Ruskin University, said: “It is clear from our study that there are significant differences between genders.

“Although women were overall less physically active than men, we found an association between physical inactivity and obesity in men, but not in women. This indicates that, especially in people with vision and hearing losses, exercise and being active has a very important role in preventing obesity for men.

“Adults, especially those with sensory losses, should be encouraged to be as physically active as possible but there are obviously challenges, strongly suggesting that intervention and encouragement would play a very important role.

“An effective strategy to increase the levels of physical activity in this population group would be through targeted intervention programmes based on health awareness on the importance of physical activity.”

Dad tips we take for granted but go a long way

With all the pressure that comes with responsibilities, dads also need to look after their own wellbeing too.

There is no one-size-fits all way to being a father, but most working dads want to do the best to support their loved ones. With all the pressure that comes with these responsibilities, dads also need to look after their own wellbeing too. 

Donato Avellana is the Health and Wellbeing Lead for the Vibe Team at Canva Philippines, and as a father himself, he acknowledges the importance of work-life balance. He has helped build programs at Canva that empower employees to have a healthy work-life balance, with holistic programs for all domains of wellness. Taking his learnings from this, he shares some helpful and practical tips to help dads to develop healthy habits that can boost their happiness at work and at home. 

1. Rest and recover well

Rest and relaxation is crucial to improve our overall health. Try your best to get at least 7 hours of sleep, go to bed an hour before you go to sleep, and stay away from your TV or mobile phone, as several studies show that the blue light from screens can disrupt sleep. Sleep is often a neglected component of overall well-being, but this is where the body repairs itself to get ready for another day. Remember that you deserve to rest.

2. Start your day with a cold shower 

Showering can also offer more benefits than many realise.  By using water that is a little cold, you can improve blood circulation, with the lower temperature causing blood to run to the skin’s surface. Good blood circulation plays an important role in our health for proper nutrient distribution throughout our body.

This is also a good time for dads to have their ‘me’ time. Breathing exercises are a great way to start the day, by offering the opportunity to regroup and reflect. 

3. Move more, make it a habit

The health benefits of movement have been scientifically proven time and time again. Your body is connected to your brain and your movement habits can positively impact how you think and feel. Inactivity can make you feel sluggish and tired, making it hard to find motivation and deliver on responsibilities.

Add regular walks, stand often, or follow stretching routines that you can commit to during the day. Taking time for a short 10-15-minute walk is a great way to have a mental and physical break.

4. Eat smart: practice a mindful eating habit. 

We have been educated about what healthy eating is since we were kids. Eating intuitively on a regular schedule is very important. Eating with no structure creates mindless eating that can lead to poor nutrition choices. Think of nourishing your body with healthy fuel for efficient performance instead of just eating. Eat a variety of whole foods, have fruits and vegetables, and hydrate smartly.

5. It’s okay to ask for help

This shortlist might not be easy for everyone, so I encourage dads to seek help when they need it. You might want to start at home with your spouse, ask for help from co-workers, peers, fellow fathers, professionals such as your doctor.

Showing appreciation to your father

If you’re still looking for heart-felt gift ideas for your dad, you can browse through Canva for free design ideas and inspiration.
