Scented candles have taken the market by storm. Known to be therapeutic, these candles are quickly making their way into our houses. However, researchers have raised the flag over the toxicity of one of its components—Terpenes. A new study has shown that particles eliminated from burning scented wax melts indoors can create a "tremendous amount" of indoor air pollution, similar to that created by pollution caused by diesel engines. Intrestingly, Terpenes are the components that give wax candles its scent.
Since these particles actively alter indoor air chemistry, they could have significant health implications. The processes should be considered in the design and operation of buildings and their HVAC systems to reduce the exposure. Zepbound helped nearly 25% more participants lose more than 15% of their weight compared to Wegovy, Lilly said on Sunday.
Trial also showed that treatment with Terpenes are naturally occurring volatile organic compounds (VOCs) found in many plants and are commonly used in household products like air fresheners, scented candles, cleaning agents, and essential oils. While they contribute pleasant aromas, terpenes can significantly impact indoor air quality through chemical reactions that produce harmful pollutants.
When terpenes are released indoors, they can react with oxidants such as ozone (O₃) and hydroxyl radicals (OH), leading to the formation of secondary pollutants:([PubMed][1])
Secondary Organic Aerosols (SOAs): These are fine particulate matters formed from the oxidation of terpenes. SOAs can penetrate deep into the respiratory system, potentially causing health issues.([PubMed][1])
Formaldehyde: A known irritant and potential carcinogen, formaldehyde can form as a byproduct of terpene reactions.([PubMed][2])
Ultrafine Particles: Particles smaller than 100 nanometers can result from these reactions, posing risks due to their ability to enter the bloodstream.
These reactions are particularly concerning in enclosed spaces with limited ventilation, where pollutant concentrations can accumulate to levels that may affect human health.
Notable Study: Purdue University Research on Scented Wax Melts
A study conducted by Purdue University investigated the impact of scented wax melts on indoor air quality. The researchers found that burning these products releases terpenes, which react with indoor ozone to form nanoparticles. The concentration of these particles was comparable to those emitted by diesel engines, highlighting a significant source of indoor pollution. The study emphasized the need for further research into the health implications of these particles and suggested that building designs and ventilation systems should account for such chemical processes to minimize exposure.

Finding your keys, remembering a name, or forgetting what you needed at the store happens to everyone. But while it's normal to be forgetful sometimes, it's also important to take care of your memory.
When you're about to learn something new, sleep is a crucial first step. Scientists have found that sleep before you learn actually prepares your brain to take in new information. Without enough sleep, your ability to learn new things can drop by as much as 40%.
This is because a lack of sleep affects a part of the brain called the hippocampus, which is essential for making new memories.
After you've learned something, sleep is even more important. When you first form a memory, it's very fragile. Your brain uses sleep as a special time to go back through recent memories and decide which ones to keep.
During the deep stages of sleep, memories become more stable and firm. Research has even shown that memories for skills, like playing a song on the piano, can actually get better while you're asleep. After deep sleep, REM (Rapid Eye Movement) sleep—the stage where you dream—helps to link related memories together in new and unexpected ways. This is why a full night of sleep can help with problem-solving. REM sleep also helps you process and reduce the intensity of emotional memories.
It's a well-known fact that our sleep patterns change as we get older. Unfortunately, the deep sleep that is so important for strengthening memories starts to decline in our late 30s. A study found that adults over the age of 60 had a 70% loss of deep sleep compared to young adults (ages 18-25). This reduction in deep sleep was directly linked to having a harder time remembering things the next day.
Scientists are now looking into ways to improve deep sleep in older people. Since there are few medical treatments for memory problems in old age, improving sleep could be a very promising way to help people hold onto their memories as they get older. Ultimately, whether you are a student or an older adult, it's important to know that the sleep you get after you study is just as vital as the sleep you get before you study. When it comes to sleep and memory, you get very little benefit from cutting corners.
Here are some simple ways you can keep your brain health in check.
Exercise gets blood flowing to your entire body, including your brain. This can help keep your memory sharp. Try to get at least 150 minutes of moderate activity, like walking fast, each week. Even a few 10-minute walks a day can help.
Just like exercise strengthens your body, mental activities keep your brain strong. To help prevent memory loss, try things like reading, doing puzzles, playing games, or learning a new skill or musical instrument.
Being social can help you avoid stress and depression, both of which can lead to memory loss. Make an effort to spend time with friends and family, especially if you live alone.
When things are messy, it's easy to forget. Use a notebook, calendar, or digital planner to keep track of tasks and appointments. To help remember things, you can repeat them out loud as you write them down. Keep important items like your keys and wallet in the same spot so you can always find them.
Not getting enough sleep can be linked to memory loss. Aim to get 7 to 9 hours of sleep each night on a regular basis. If snoring or restless sleep is an issue, talk to your doctor, as it could be a sign of a sleep problem.
A healthy diet is good for your brain. Make sure to eat plenty of fruits, vegetables, and whole grains. Also, choose lean proteins like fish and beans. Be mindful of how much alcohol you drink, as too much can cause confusion and memory loss.
Follow your doctor's advice for managing any long-term health issues like high blood pressure, diabetes, or depression. Taking good care of your body can help you take better care of your memory. It's also a good idea to talk to your doctor about any medicines you take, as some can affect your memory.

The phrase, “hell hath no fury like a woman scorned” may hold more truth than we led on. Women are always thought of as the less aggressive, more forgiving and expected to be more rational than men. However, how much of that is a biological factor and how much of it is societal expectation?
While many people believe women are more forgiving, the results of many studies suggest otherwise. This 1997 research, which was published in the Proceedings of the National Academy of Sciences (PNAS) USA, compared men and women to see if there were differences in how they forgive. The study looked at how forgiving people are in general, as well as how they forgive themselves, others, and situations they can’t control.
The study, which included 625 people (mostly women), found that men were more forgiving overall than women. Men also showed a greater willingness to move past feelings of unforgiveness. However, when it came to the more positive aspects of forgiveness, like being accepting and compassionate, there was no major difference between the genders.
Both men and women in the study showed similar emotional patterns related to forgiveness. Things like negative emotions, anxiety, and holding in anger were all linked to being less forgiving. On the other hand, positive emotions were linked to being more forgiving. An interesting difference was seen with anxiety control: for women, controlling their anxiety was linked to being less forgiving, but for men, it was linked to being more forgiving.
The study found that a person's gender can change the way certain emotions are connected to forgiveness. This was especially true for forgiving oneself and forgiving situations that are out of one's control. Forgiveness of others, however, was not significantly affected by these gender differences. This suggests that while everyone's emotions play a role in forgiveness, gender can influence how those emotions shape our ability to let go of certain types of hurt.
Another 2021 study, published in the Journal of Religion and Health, on average, men were more forgiving than women, especially when it came to overcoming feelings of unforgiveness toward themselves and situations they couldn't control. However, there was no significant difference in the more positive aspects of forgiveness, such as a compassionate mindset.
An interesting finding was how controlling emotions affected men and women differently. For women, trying to control their anxiety was linked to being less forgiving. For men, controlling their anxiety was actually linked to being more forgiving, particularly of themselves and difficult situations.
According to a study published in the Biological Psychiatry, the study showed that when serotonin was low, the connection between two key brain areas became weaker. To find this, researchers adjusted the diets of healthy volunteers to lower their serotonin levels. Using an fMRI brain scan, they observed how the volunteers' brains reacted to faces showing angry, sad, or neutral expressions. They found that these 2 areas of the brain became weak,
The researchers also gave the volunteers a personality test to see who had a natural tendency toward aggression. They found that in these individuals, the link between the amygdala and the prefrontal cortex was even weaker when serotonin was low. This means that people who are already more prone to aggression are the most sensitive to drops in serotonin, which makes it even harder for them to control their angry feelings.
These findings highlight that while everyone's emotions play a role in forgiveness, gender can influence how those emotions shape a person's ability to let go of certain types of hurt.
Actress Miriam Margolyes, known for her role as Professor Sprout in the Harry Potter films, recently spoke openly about her health issues. In a new interview, the 84-year-old admitted her lifestyle has taken a toll on her body, which she links to a lifelong struggle with her weight.
When asked about using Ozempic for weight loss, Margolyes firmly rejected the idea, stating, "That’s for diabetics. You shouldn’t take medicine meant for people who are really sick."
Her health struggles have also led to her considering her own mortality. After a recent heart procedure, she shared that she knows she "doesn’t have long left to live," likely within the next five to six years. Despite this, she expressed a strong desire to continue performing, even though she isn't "strong enough" for roles that don't involve a wheelchair.
In May 2023, Margolyes was hospitalized with a chest infection and underwent a heart procedure. She later updated fans on social media, thanking them for their support.
The procedure she had was a Transcatheter Aortic Valve Implantation (TAVI), a less invasive alternative to open-heart surgery. On a podcast, she explained that she had an aortic valve replaced with one from a cow. "I’ve got a cow’s heart now," she joked. "I’d never heard of that operation, but it saves you from having open heart surgery."
Beyond her heart issues, Margolyes has also been diagnosed with spinal stenosis, a condition that causes chronic pain and makes it difficult for her to walk. She has registered as disabled and uses a walker and sticks, though she recently got a mobility scooter, which she called "a lot of fun."
"I’ve let my body down," she said. "I haven’t taken care of it. I have to walk with a walker now. I wish I’d done exercise." Miriam admitted in the magazine interview. According to the National Institute on Aging, being physically active is pertinent for one’s health.
As you get older, your heart and blood vessels naturally change. While your resting heart rate usually stays the same, your heart may not be able to beat as fast as it used to during exercise or stressful situations.
As you get older, it's not unusual to feel your heart flutter or skip a beat from time to time. Most of the time, this is nothing to worry about. But if you feel like your heart is fluttering or racing very often, or if the feeling doesn't go away, it could be a sign of a heart rhythm problem called an arrhythmia. If this happens, it's a good idea to talk to a doctor, as it might need treatment.
With age, your heart’s size and structure can change. The walls of your heart can get thicker, and its chambers can become bigger. This can make it harder for the heart to hold as much blood as it used to. A thicker heart wall also raises the risk for a common heart rhythm issue called atrial fibrillation, which can increase the chance of having a stroke.
The heart’s valves, which open and close to control blood flow, can also get stiffer and thicker. This can slow down or block the blood flow out of your heart, or they can become leaky. When this happens, fluid can start to build up in your lungs, legs, and feet.
The natural changes in your heart that come with age can increase your risk of heart disease, which can limit your daily activities. It’s also interesting to know that many of the things that are bad for your heart are also bad for your brain. For example, high blood pressure can increase your risk of both heart disease and dementia later in life.
The good news is that you can take steps to protect both. By managing your blood pressure and taking good care of your heart, you are also helping to protect your brain and improve your overall well-being as you get older.
