Air conditioner bumps the electric bill by 42%, increasing the risk of energy poverty
The actual increases will depend on the intensity of the change in climate households will have to face in the future. Those additional spendings are thus a new factor influencing the energy poverty of the poorest households, a situation arising when the families spend more than 5% of their annual income on electricity.
A new study published in Economic Modelling by researchers at Ca’ Foscari University and CMCC shows that owning and using an Air Conditioner greatly increases the electricity bills of households, with important implications for the energy poverty of the less well-off.
Previous studies, mainly focused on the US, estimated an increase of household spendings for electricity bills of about 11%. This new study, analysing the socio economic characteristics of households in eight other OECD countries (Australia, Canada, France, Japan, the Netherlands, Spain, Sweden, and Switzerland) and climate data coming from a NASA dataset, finds that on average, using an AC brings 42% more spending for electricity bills, with respect to the ones who do not have an AC unit in their home.
The actual increases will depend on the intensity of the change in climate households will have to face in the future. Those additional spendings are thus a new factor influencing the energy poverty of the poorest households, a situation arising when the families spend more than 5% of their annual income on electricity.
According to BPIE, in 2014 the population already affected by fuel poverty in Europe ranged from 10% to 15%, depending on the member state. This new study shows a more worrying situation.
“The concept of energy poverty is usually related to ensuring adequate heating during the coldest months – explains Enrica De Cian, professor of Environmental Economics at Ca’ Foscari and leader of the Energya team which drafted the study. – Our data, however, indicate that we should widen the concept to include the increasing role of cooling during the summer months. Poorest households already spend a consistent share of their budget for basic goods such as food and electricity. The latest will have to increase to ensure adequate protection of our health especially among the most vulnerable members of households during heatwaves.”
Owning an AC has already important implications for the energy expenditures of households, up to the scale of countries and beyond, with great variations across countries: it represents about 11% of the total final energy use in buildings in the US, while only 1.2% in Europe.
“Our analysis reveals that in Spain 18.5% of households already spend more than 5% of their annual budget in electricity – confirms the Venitian professor. Those percentages are generally higher in coldest countries, reaching for instance 24.2% in Sweden. In France and Switzerland, we find lower numbers, respectively 8% and 5%.
Who uses ACs and why
“The innovative element of this work – adds Teresa Randazzo, first author of the study – is that we take into account drivers of AC adoption and use in households that are difficult to observe and measure, such as the personal perception of thermal comfort, the risk aversion, or the environmental awareness.”
The study disentangles the various characteristics of individuals and households to point out to the ones leading – or not – to a wider AC adoption. For instance, a larger share of younger members brings a wider adoption of AC, while more educated individuals tend to use those appliances less, suggesting they are more aware of the impact of energy on the environment.
Similarly, households that are more accustomed to adopting energy-saving behaviors are less likely to adopt AC. On the opposite, those with a high number of appliances tend to have a higher propensity for AC – which may be an indication that those used to higher standards of comfort are also more inclined to adopt AC.
“Living in an urban area increases the probability of having AC by 9 percentage points, a sizable effect compared to the role of income and climate, probably due to the heat island effect in cities” adds Malcolm Mistry, responsible for the climate data analyses for the Energya project and co-author of this study.
Data analysis of households and climate
To understand the dynamics of AC adoption in industrialized countries and its impact on the budget of households in the light of climate change, the Energya team examined eight OECD countries spanning across mid-latitudes: Australia, Canada, France, Japan, the Netherlands, Spain, Sweden, and Switzerland.
To do so, the researchers combined the information of 3,615 geocoded households from a dataset released by the OECD with a historical climate dataset based on NASA-GLDAS data. “Our elaboration of this climate dataset includes Cooling Degree-Days (CDDs) for the last 49 years, an indicator commonly used in the literature to capture the typical intensity and duration of warm days, and the corresponding cooling requirements” explains Malcolm Mistry.
AC global trends
From 1990 to 2016 global annual sales of air conditioners more than tripled to reach 135 million units worldwide, with figures from the residential sector alone underscoring the trend. China leads, with 41 million residential units registered, followed by 16 million in the US, and roughly 9 million in both Japan and Europe. Penetration of air conditioning in households is expected to continue to increase sharply, because of climate change and thanks to increasing standards of living, reaching 21% in Spain and 35% in France in 20 years from now” concludes prof. De Cian.

5 Tips to upgrade your sleep
Sleep contributes to better brain function, memory, concentration and lower stress. According to the National Institutes of Health, most adults need 7-9 hours of sleep every night to achieve maximum health benefits.
Good sleep isn’t just about waking up feeling rested and ready for the day. Quality sleep, and plenty of it, is important for your overall health. While you sleep, your body naturally recharges itself, which puts you at lower risk for cardiovascular problems and chronic conditions like diabetes, as well as improving your immune system.
Sleep also contributes to better brain function, memory, concentration and lower stress. According to the National Institutes of Health, most adults need 7-9 hours of sleep every night to achieve maximum health benefits.
If you’re falling short of the recommended amount of sleep, you may be able to make some adjustments that help you reap the health benefits of better rest. Learn what you can do to improve your sleep with these tips from the experts in safer, healthier sleep at Naturepedic.
Reduce Light Exposure
Your body’s natural circadian rhythms are closely aligned with light and dark. When your body senses light, it sends signals to your brain that it’s time to be awake. Light also suppresses your body’s production of melatonin, a hormone linked to sleep. Cutting back on bright lights and avoiding devices at least an hour before bed can tell your body it’s time to wind down, and sleeping in a dark room promotes better rest.
Invest in the Right Mattress
Your mattress plays a major role in your comfort through the night, so making sure it fits your needs is an important step toward getting better rest. Take control of your comfort with a quality mattress such as Naturepedic’s EOS (Ergonomic Organic Sleep) mattress, which is handcrafted and made without polyurethane foam, formaldehyde, flame retardants or fiberglass. The breathable layers of certified organic cotton, wool and GOTS-approved latex ensure better temperature regulation while naturally contouring the body. An added feature is the ability to customize each side of the bed by opening the zippers and adjusting the layered components for the perfect comfort combination.
Find the Right Sheets
Sheets that are too stiff, scratchy or otherwise unpleasant make it nearly impossible to settle in for a good night’s rest. Higher thread counts tend to be softer, higher quality sheets. However, you may need to experiment to find which material suits you best.
Set a Comfortable Temperature
When you’re too hot or cold, your mind tends to focus on those sensations rather than allowing you to slip into a slumber. Set your thermostat at a comfortable temperature, adding fans or adjusting the layers of bedding as necessary to achieve the perfect level of cozy comfort.
Use a Sound Machine
If you’re a light sleeper, noise can wreak havoc on your rest. Many people find sound machines offer two key benefits: They provide a soothing sound, such as rain or ocean waves, that allows you to relax and ease into slumber and constant background noise, so additional sounds are less disruptive.

What you should know about IBD
Two common conditions are irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). They’re often confused for one another, but these are actually two different GI disorders.
It may not be something you like to talk about, but if you have gastrointestinal (GI) problems, your symptoms may be far more common than you think. According to data from the American Gastroenterological Association, 60-70 million people living in the United States have gut health concerns.
Two common conditions are irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). They’re often confused for one another, but these are actually two different GI disorders.
IBS is a syndrome; it is defined by a group of symptoms, does not cause inflammation and rarely requires hospitalization or surgery. IBD, on the other hand, is an umbrella term used to describe disorders that cause chronic inflammation of your GI tract.
The disease is more common than you may realize; a study led by the Crohn’s & Colitis Foundation found nearly 1 in 100 people living in the U.S. have IBD. The two most common forms of IBD are Crohn’s disease and ulcerative colitis.
Understanding IBD Symptoms
Because it poses serious health risks and can cause permanent damage to your intestines, it’s important to be aware of what IBD is and recognize the symptoms. Your primary care doctor or gastroenterologist can help if you have concerns about these symptoms:
- Intense, crampy pain that doesn’t go away in a day or two or has been present on and off for weeks or longer
- A notable change in bowel movement frequency, whether more or less often
- Frequent diarrhea over several weeks, or loose stools multiple times a day
- Frequent constipation, or constipation alternating with diarrhea
- Urgency on a regular basis or inability to hold back the bowel movement before reaching the bathroom
- Blood with bowel movements
- Mucus in your stool regularly or paired with pain or other symptoms
- Always feeling as though you aren’t fully emptying your bowels
Other symptoms that may have a variety of causes but need extra attention especially if you notice them along with any of the symptoms above include pain outside of the gut, fatigue, loss of appetite and weight loss. In addition, children with IBD may have delays in growth and the onset of puberty.
Diagnosing IBD
No single test can confirm a Crohn’s or ulcerative colitis diagnosis. Your medical history and information obtained from diagnostic testing can exclude other potential causes of your symptoms, since gastrointestinal symptoms are common and can have a variety of causes.
Your first tests will likely include blood and stool laboratory tests. Further testing could include imaging studies of your gastrointestinal tract or a look inside your GI tract through an endoscope.
Identifying Treatment Options
Once an IBD diagnosis is confirmed, you can partner with your doctor to manage your disease. Treatment plans are highly personalized, as what works for one person may not for another. Medication and managing your diet and nutrition are two common treatment recommendations. In some cases, surgery can help improve your quality of life.
Clinical trials may also be an option for treating your IBD. Through clinical trials, researchers find new ways to improve treatments and quality of life. In fact, clinical trials represent the final stages of a long and careful research process to make new and improved treatment options for patients available.
However, an important part of clinical trials for IBD is patient participation. Without the enrollment of patients in clinical trials, new treatment options for IBD can be delayed or never become available.
Equally important to this process is having a diverse representation of patients that considers race, age or other categories. This helps researchers develop treatments that meet the needs of a vast IBD patient community.
If you’re interested in participating in a clinical trial, ask your doctor to help you find a trial that is right for you, and visit crohnscolitisfoundation.org to learn more about IBD and treatment options, including clinical trials.

Unlocking the science of sleep: How rest enhances language learning
Getting eight hours of sleep every night helps the brain to store and learn a new language.
Sleep is critical for all sorts of reasons, but a team of international scientists has discovered a new incentive for getting eight hours of sleep every night: it helps the brain to store and learn a new language.
A study led by the University of South Australia (UniSA) and published in the Journal of Neuroscience has revealed that the coordination of two electrical events in the sleeping brain significantly improves our ability to remember new words and complex grammatical rules.
In an experiment with 35 native English-speaking adults, researchers tracked the brain activity of participants learning a miniature language called Mini Pinyin that is based on Mandarin but with similar grammatical rules to English.
Half of the participants learned Mini Pinyin in the morning and then returned in the evening to have their memory tested. The other half learned Mini Pinyin in the evening and then slept in the laboratory overnight while their brain activity was recorded. Researchers tested their progress in the morning.
Those who slept performed significantly better compared to those who remained awake.
Lead researcher Dr Zachariah Cross, who did his PhD at UniSA but is now based at Northwestern University in Chicago, says sleep-based improvements were linked to the coupling of slow oscillations and sleep spindles – brainwave patterns that synchronise during NREM sleep.
“This coupling likely reflects the transfer of learned information from the hippocampus to the cortex, enhancing long-term memory storage,” Dr Cross says.
“Post-sleep neural activity showed unique patterns of theta oscillations associated with cognitive control and memory consolidation, suggesting a strong link between sleep-induced brainwave co-ordination and learning outcomes.”
UniSA researcher Dr Scott Coussens says the study underscores the importance of sleep in learning complex linguistic rules.
“By demonstrating how specific neural processes during sleep support memory consolidation, we provide a new perspective on how sleep disruption impacts language learning,” Dr Coussens says. “Sleep is not just restful; it’s an active, transformative state for the brain.”
The findings could also potentially inform treatments for individuals with language-related impairments, including autism spectrum disorder (ASD) and aphasia, who experience greater sleep disturbances than other adults.
Research on both animals and humans shows that slow oscillations improve neural plasticity – the brain’s ability to change and adapt in response to experiences and injury.
“From this perspective, slow oscillations could be increased via methods such as transcranial magnetic stimulation to accelerate aphasia-based speech and language therapy,” Dr Cross says.
In future, the researchers plan to explore how sleep and wake dynamics influence the learning of other complex cognitive tasks.
“Understanding how the brain works during sleep has implications beyond language learning. It could revolutionize how we approach education, rehabilitation, and cognitive training.”
