On Monday night, a magnitude 6.6 earthquake struck Japan, leading to a tsunami warning. Fortunately, authorities reported minimal damage, and the warning was soon lifted. According to local media, there was only one minor injury involving a man who fell at his own home.
Japan, located in the Pacific Ring of Fire, experiences approximately 1,500 tremors annually. However, these quakes have a long-lasting impact on one's health—both physical and mental.
1. Wound Infections
Earthquake-related injuries range from cuts and bruises to fractures and crush injuries. If not attended to on time, these wounds can lead to infections like sepsis, tetanus, or even amputations if untreated. Regions with scarce medical resources face higher risks of untreated injuries and antimicrobial resistance. Ensuring prompt medical care and deploying teams to assess building safety is critical to preventing further injuries and fatalities.
A recent study examined infections in 225 earthquake survivors with musculoskeletal injuries treated between February and April 2023. It found that gram-negative bacteria were common in the wounds of the victims. Acinetobacter baumannii (49.4%) and enterococci (28.6%) were the most prevalent. Many pathogens were multidrug-resistant, with 76% from wound cultures and 58% from deep tissue cultures showing resistance. Common infections included surgical site infections (32.8%), urinary tract infections (5.3%), bloodstream infections (5.7%), and pneumonia (0.4%). Intensive care was required for 35.6% of patients, with a mortality rate of 2.7%.
2. Infectious Diseases
Earthquakes disrupt water supplies, leading to unsanitary conditions that spread waterborne diseases such as cholera. Meanwhile, it also pushes people to take shelters in dingy places, which can outbreaks of measles, respiratory illnesses, and parasitic infections like leishmaniasis. Cold conditions and stress suppress immunity, increasing the risk of disease spread.
3. Chronic Conditions
Access to medication and medical care is often disrupted by earthquakes. Studies show increased rates of heart attacks, strokes, and diabetes following earthquakes due to stress and disrupted routines. Destruction of health records and facilities exacerbates these issues, especially in disaster-prone regions.
4. Healthcare Disruption
Damaged medical facilities and transport links hinder healthcare delivery. Pregnant women and individuals with chronic diseases face heightened risks. Refugees and displaced populations encounter accessibility barriers to healthcare services.
5. Psychological Trauma
Survivors of these earthquakes often suffer from anxiety, depression, and Post Traumatic Stress Disorder (PTSD). Tailored mental health programs are crucial for recovery, especially for those already living in conflict zones or displacement.
On April 14 2010, a 7.1-magnitude earthquake struck Qinghai Province, China, devastating Yushu County. A psychological relief study, published in the Journal Of Affective Disorders in 2011, assessed the mental health of 505 survivors three to four months post-disaster. Using tools like the PTSD Checklist-Civilian version (PCL-C) and Hopkins Symptoms Checklist-25 (HSCL-25), the study found prevalence rates of 33.7% for probable PTSD, 43.8% for anxiety, and 38.6% for depression, with one-fifth of participants experiencing all three. Key risk factors included being female, experiencing intense fear during the quake, and having limited social support, as measured by the Perceived Social Support Scale (PSSS).

Halloween may bring an abundance of sweets and chocolate, but a few of these treats could carry health risks that have nothing to do with sugar. Mixing certain confectionery with prescription medication can cause unexpected side effects, especially for people being treated for depression, anxiety, or heart conditions. Kiran Jones, a Clinical Pharmacist at Oxford Online Pharmacy, explained which medicines could be affected, ranging from stronger adverse reactions to reduced drug effectiveness, and what ingredients should be avoided.
While enjoying Halloween treats in moderation is harmless for most people, those taking regular medication should be cautious. Some common ingredients in candies, especially artificial sweeteners, caffeine, liquorice, and food coloring can interfere with how medicines work. Even small amounts can alter absorption, increase side effects, or counteract the intended effect of the drug.
Artificial sweeteners such as aspartame can interfere with neurotransmitters affected by Monoamine Oxidase Inhibitors (MAOIs). These medicines are prescribed to treat depression, anxiety, and Parkinson’s disease by preventing the breakdown of neurotransmitters in the brain.
When combined with aspartame, these drugs can lead to an excessive build-up of neurotransmitters, resulting in high blood pressure, headaches, nervousness, or trouble sleeping.
Jones explained, “People taking these medications should avoid or limit foods containing aspartame to prevent these potentially serious reactions.”
Sugar-free sweets, diet drinks, and low-calorie snacks often contain artificial sweeteners like aspartame, while caffeine is commonly found in chocolate and coffee-flavoured candies. For those on ADHD medication, anti-anxiety pills, or blood pressure drugs, caffeine can significantly alter how the medicine behaves.
It can heighten the stimulant effects of drugs such as Adderall while weakening the calming impact of SSRIs. Similarly, caffeine may counteract beta-blockers used for blood pressure control by raising heart rate and blood pressure. This interaction can cause symptoms like palpitations, restlessness, poor sleep, and in severe cases, an increased risk of stroke or heart attack.
People taking medication for blood pressure, water retention, or irregular heart rhythms should be cautious with liquorice sweets. Liquorice contains glycyrrhizin, a compound that reduces potassium levels and increases sodium retention in the body, which can lead to higher blood pressure and fluid retention.
This effect directly interferes with blood pressure and heart medications, making them less effective and potentially causing uncontrolled hypertension. Regular or excessive consumption could also worsen heart rhythm problems.
Those taking antihistamines for allergies should watch out for colourful candies like M&Ms or Skittles. Artificial food dyes in such sweets can trigger the release of histamines—the same compounds antihistamines are meant to block.
This can weaken the effectiveness of the medication and, for sensitive individuals, cause allergic responses such as itching, hives, or swelling. Even if the reaction is mild, repeated exposure can reduce the benefit of the medicine over time.

We all have habits we know are bad for us, yet we don’t stop doing them. Most smokers know that smoking is bad for their health, and even say they would like to quit, but something stops them. The National Institute of Health (NIH) explains how 70% smokers say they would like to quit, people who abuse drugs and alcohol also wish to give up their addiction but find it extremely difficult.
As such, there are many habits, people think do not harm them, but can take a toll on their body. In a recently posted video, Cardiologist Dmitry Yaranov, listed 5 habits that are slowly chipping away at your health.
In the video caption, Dr Yaranov explained that these habits, often picked up by mistake, can make your body weaker and more susceptible to illnesses.
Telling yourself, "I'll sleep when I'm dead," is a shortcut right to that outcome. Chronic lack of rest isn't just tiring; it’s physically damaging. Skimping on sleep constantly raises your blood pressure, makes you gain weight, and guarantees a serious burnout that you won't be able to recover from easily. Prioritize rest now.
From your office chair to the car and the couch, sitting for too many hours is silently wrecking your health. Being constantly still tightens your back, slows down your metabolism, hurts your digestion, and weakens your heart. Your body needs regular movement to survive, not just a ten-minute walk. Get up and move more often.
Saying "I'm fine" while carrying the weight of the world is a dangerous habit. Eventually, your body will stop listening to your mind. Stress you try to ignore explodes into physical problems, like unexplained chest tightness, constant gut issues, severe insomnia, and sudden panic attacks. Acknowledge your stress before it breaks you.
Skipping your morning meal, grabbing drive-thru lunch, and relying on sugar for quick energy creates chaos inside you. This erratic eating causes your blood sugar to swing wildly, stressing every major organ. Your body needs consistent, nutritious fuel, not a constant roller coaster of sugar and grease. Feed your body well, not fast.
You are always available, doing favors and taking on tasks for everyone else. But when was the last time you put your own needs first? Overcommitting drains your energy, time, and mental resources until there’s nothing left. This chronic neglect leads to resentment and exhaustion. Guard your boundaries and put yourself on the list.
Kicking any kind of habit can be difficult. The NIH explains that habits are just routines that we do without thinking. They are a normal, often helpful part of life, but they can also be things that harm your health.
While some habits are useful and do not require a lot of thinking, like brushing, showering, driving, other habits are based off-of pleasure or dopamine hit like smoking. Both types of habit use the same mechanics, but pleasure-based habits are much harder to break because of a chemical called dopamine.
The good news is that humans are not completely controlled by habit. We have other brain areas that can help us make better choices for our long-term health. There is no single solution; what works depends on the person. Dr. Volkow emphasizes that it's "not one size fits all." However, scientists recommend a few helpful techniques:
Figure out the exact time and place where your bad habit happens. Knowing your triggers is the first major step toward taking back control. Next, make a plan to avoid those spots. If the candy machine is your weakness, take a different route. Stay away from people who tempt you.
Before you face a tempting situation, close your eyes and picture yourself succeeding. Imagine choosing water over a sugary drink. Mentally rehearsing the healthy choice can prepare your brain. This practice boosts your chances of making the right decision when the real moment arrives.
Don't just stop the bad habit; actively replace that routine with a new, healthy activity. Fill the void with something constructive. Many people successfully replace strong urges, even addictions, with intense exercise like running. A new ritual helps fight the old habit's pull.

As COVID and viral infections cases rise in numbers, researchers are finding out how, following the bout of cases, the risk of heart diseases has also increased in people. To explore this connection, new research published today in the Journal of the American Heart Association reveals a strong link between both acute and chronic viral infections and an increased risk of serious cardiovascular events, such as heart attacks and strokes.
The lead author, Dr. Kosuke Kawai, noted that while we know viruses can cause cancer, their link to non-infectious diseases like heart disease hasn't been clear. This study confirms that acute (short-term) and chronic (long-term) viral infections are connected to both immediate and lasting risks for heart and brain events.
When your body fights off a virus, your immune system releases chemicals that cause inflammation (swelling) and make your blood more likely to clot. Both of these problems can linger even after the virus is gone.
This ongoing inflammation and tendency to clot can damage the heart and blood vessels, which is likely why the risk of a heart attack or stroke spikes so dramatically right after an illness.
The research details what happens to your heart risk right after you get a respiratory infection. The study combined data from many high-quality reports and found a major, temporary jump in risk:
In the month immediately following a confirmed flu infection, people were 4 times more likely to have a heart attack and 5 times more likely to have a stroke compared to when they weren't sick.
After a COVID infection, the risk was also high. People were 3 times more likely to have a heart attack and 3 times more likely to have a stroke in the first 14 weeks. Worryingly, this risk stayed higher than normal for an entire year.
This part of the study focused on people who have had certain chronic (long-lasting) viral infections, tracking their health for an average of over five years to see if their risk remained high:
People with HIV had a 60% higher risk of heart attack and a 45% higher risk of stroke.
This infection was linked to a 27% higher risk of heart attack and a 23% higher risk of stroke.
Even this common virus was associated with a 12% higher risk of heart attack and an 18% higher risk of stroke.
Even though these percentage increases are smaller than the immediate post-flu/COVID jump, they are still very important because the risk lasts for years. Shingles, for example, affects about one in three people in their lifetime, meaning that this seemingly small increase in risk will lead to a large number of extra heart problems across the general population over time.
The study suggests a powerful way to fight these risks is by getting vaccinated. The findings strongly support the idea that increasing the number of people who get flu, COVID, and shingles shots could lower the overall rate of heart attacks and strokes in the community. As an example, previous research has shown that getting a flu shot can be linked to a 34% lower risk of major heart problems.
The American Heart Association recommends that everyone, especially those with existing heart conditions or heart risk factors, talk to their doctor about getting the right vaccines. Vaccination is a simple step that offers crucial protection to people whose hearts are already vulnerable.
It’s important to remember that this study was based on looking at people's health records (observational studies), not on controlled experiments. The main focus was on single viruses. Researchers noted that we still need more studies to fully understand how some other viruses, like dengue and HPV, might be linked to heart disease.
