Mysterious Fog in the US , Canada and UK: A dense, eerie fog with a "burning chemical-like smell" has spooked a good part of North America and parts of the United Kingdom and Canada. With social media amplifying all concerns, this phenomenon has sparked attention across all social media platforms. However, at the heart of this mysterious fog are a conjunction of natural events, social psychology, and environmental conditions that culminated in all the conspiracy theories and public health fears. Here's a closer look at the mysterious fog, its potential causes, and the societal response it has triggered.

Fog that Feeds Fear

The first reports of this "mysterious fog" came in from Florida where a resident said that they experienced respiratory symptoms, feverish warmth, and stomach cramps after contact with the fog. Similar stories started flooding social media, and within a day or two, a sinister force seemed to sweep across the United States, Canada, and parts of the UK. From Texas to Minnesota, people reported weird odors and health issues that they thought were linked to this bizarre atmospheric event.

Some witnesses were said to see "white particles" swirling through the air; theories ranged from a chemical attack or experimental weapon to drone-related chemical dispersals and references to historical military experiments, such as the infamous 1950s "Operation Sea-Spray."

Fuel to the fire were added when videos and posts, hundreds of thousands in number, began circulating on social media sites like TikTok and X (formerly Twitter) speculating on the origin of the fog. Hashtags like #ToxicFog went trending for days. Hysteria created a self-reinforcing loop in which every post spurred further scrutiny and fear.

Scientific Explanation of the Dense Mysterious Fog

1. What is Fog?

Fog is essentially a low-lying cloud formed when the air temperature cools to its dew point, causing water vapor to condense into tiny droplets or ice crystals. Several types of fog—advection fog, radiation fog, and valley fog—can form depending on conditions such as warm, moist air moving over cooler land or when temperatures plummet rapidly under clear skies.

2. Why the Chemical Smell?

Such chemical-like smell as reported during the occurrence of fog events is sometimes attributed to air pollution. It acts like a sponge, where it absorbs these pollutants, which include sulfur dioxide and nitrogen oxides, among others, that emit from industries. This mixture, therefore, leads to a stench that could be mistaken as unnatural or even toxic.

3. What are the Health Concerns?

High moisture levels from fog can significantly exacerbate symptoms related to respiration, but especially in already predisposed asthmatics and allergy patients. The connection of these symptoms with actual fever, stomach cramps, and puffy eyes is too remote. Experts assume that the irritating effects of entrapped pollutants trapped in fog tend to affect more the eyes and throat rather than the rest of the body affected by some report.

Psychological Effects of Mass Panic Caused by Social Media

Social media amplified a natural weather event into a health epidemic. It made the personal experience of individuals become a cause for fear and speculation, a domino effect.

According to psychologists, this is a concept of selective perception, wherein once people's attention is drawn to environmental anomalies, they begin to notice them. This mirrors earlier panics, such as the Seattle windshield pitting panic of 1954. Then, atomic bomb testing caused fear in many and started to have people looking at their windshields for small marks that they had not seen before. Likewise, postings on the strangeness of the fog probably increased public awareness and suspicion, with people looking to attach unrelated symptoms to the phenomenon.

The fog hysteria shares a commonality with other instances of mass panic, such as the "drone sightings" of recent years or the Cold War-era fears of biological warfare.

These events underscore how fear can cloud judgment, especially when amplified by social media and sensationalist headlines. While historical cases, such as "Operation Sea-Spray," offer concrete evidence of the existence of unethical experiments, the jump from a natural weather condition to theories of chemical attacks exemplifies a more modern trend of connecting unrelated dots, all wonderfully seeded in distrust and anxiety.

Despite the swirling rumors, meteorologists and scientists are in agreement that the mysterious fog is not as alarming as it seems. It is well known that fog traps and amplifies pollutants, especially in urban and industrial regions. Moreover, winter months are the most conducive for fog formation, so its recent prevalence is unsurprising.

On the other hand, environmentalists advise that the fog should wake everyone up to increased levels of pollution. The reported odors and health irritations could be just symptoms of far deeper systemic issues like industrial emissions and lack of control over air quality.

The authorities must be transparent in their communication to combat misinformation and allay public fears. Governments and environmental agencies must provide timely updates on weather phenomena, air quality, and health risks. Initiatives like real-time pollutant tracking and public education campaigns can help demystify natural occurrences while addressing valid environmental concerns.

The mysterious Canada fog is a compelling case study in how environmental events intersect with psychology and societal dynamics. While rooted in natural phenomena, the fog became a vessel for collective fears, amplified by modern technology and historical anxieties.

In this information era where communication occurs at an almost lightning pace, the fog becomes a metaphor that reminds everyone about scientific literacy, environmental responsibility, and an effective balance when considering public concern. Whether perceived as a marvel of nature or as a tale that serves to teach, it left a very powerful mark in people's minds.

Desk jobs cause just as much damage as smoking. Several studies have stated that sitting for prolonged hours does the same amount of damage as smoking, and for that reason, experts have recommended exercise. Doctors and scientists have long said that working out is a good way to combat the damage caused by prolonged sitting hours—but a new study begs to differ. It turns out that the damage caused by sitting too much can contribute to the risk of heart disease, early death, and even type 2 diabetes. However, working out and eating right may not be sufficient to make up for this loss.

What are the physical effects of long sitting hours?

Physical inactivity refers to not engaging in vigorous or moderate workouts. Public health guidelines suggest 150 minutes of moderate-intensity workouts like cycling or brisk walking and 75 minutes of vigorous workouts like running. Sedentary behaviour, on the other hand, refers to reclining with low energy expenditure or long durations of sitting in front of a desk or television or during a long commute.

Experts say that a person can, therefore, be physically active yet live a sedentary lifestyle. Some can also go for a run before work and yet remain seated for about the next eight hours. This workout helps, but it does not combat the ill effects of sitting for long hours. When the body stays still for longer periods, a series of changes occur — skeletal muscle activity levels drop, making it difficult for the body to absorb glucose from the blood. This can result in insulin resistance and eventually type 2 diabetes.

What happens when you sit for long hours?

Blood circulation also becomes inefficient, and nutrients and oxygen take much longer to reach the tissues, thereby impairing vascular function and raising blood pressure. Together, these circulatory changes can lead to high cholesterol, belly fat accumulation, and high blood sugar. Prolonged sitting also impacts the musculoskeletal system. Limited movement and poor posture have an adverse impact on the lower back, neck, and shoulders, explaining why pains and aches are common among corporate workers.

How do long sitting hours affect mental health?

The effects of long sitting hours can impact your brain as well, reducing energy levels, alertness, and concentration. Employees who sit for extended durations are less productive and feel more sluggish at work. Globally, this leads to four to five million deaths every year, hence explaining why regular workouts are encouraged.

Can regular exercise combat the ill effects of long sitting hours?

It turns out that taking a gym membership and going for regular workouts may not be sufficient to combat the ill effects of long sitting hours. On the other hand, small and regular interruptions can make a difference. Research suggests that moving or standing up for even two to five minutes every 30 to 60 minutes can improve glucose metabolism and reduce heart-related risks too.

According to a study of offices in the UK, these measures can reduce daily sitting time by one to one and a half hours. Employees involved reported better musculoskeletal comfort, energy, and focus. This makes the message evident—regular workouts are essential, but they may not fully combat the risks associated with long sitting hours. A quick walk after lunch, attending to phone calls while taking a short walk, or even taking small breaks every now and then—these small efforts will help you protect your health better than most other remedies. For a modern corporate employee, protecting health need not be about exercising after work but about sitting less and moving more even while work is ongoing.

If you thought that the worst in terms of the heatwave was coming to an end, you were wrong. While heatwaves are an unfortunate common occurrence in India, this year is different. Earlier, in 2025, the summer brought India to its knees, with temperatures soaring as high as 50 degrees Celsius in parts of the country. And this year, temperatures have already crossed the 47 degrees Celsius mark—and reports suggest that the worst is yet to come. This year, experts are expecting the possibility of a “Super El Niño." Ever heard about it? Let’s find out what it means.

What is Super El Niño?

Super El Niño is a climate phenomenon occurring once every two to seven years. It occurs when ocean surface temperatures rise in the eastern and central Pacific. As a result, a strong event occurs, known as “Super El Niño”, which can intensify global heat.

Has India entered the El Niño phase?

The India Meteorological Department (IMD) has issued advisories for people living in heatwave-struck parts of the country. Recently, a report from AQI.in found that, out of the 100 hottest cities in the world, India is home to 95. This, in a way, makes India the hottest country in the world. Several heatstroke-related deaths have been reported in the country in the month of April itself —andthe heatwave is likely to worsen in May and June. Cities in Uttar Pradesh and Chhattisgarh are at the top of the list, as the top 10 hottest ones are in these states. Temperatures have consistently been over 40 degrees in these cities. Odisha, Karnataka, and Kerala are also in the grip of this severe heatwave.

While it cannot be conclusively said that India is in its El Niño phase, the current scenario mimics the effects already. The IMD is therefore urging people, through its advisories, to stay safe and hydrated. Extended hot days can lead to various impacts, including an increased risk of health issues like heatstroke, higher electricity consumption, and water shortages,” the advisory suggests. Experts say that India is particularly vulnerable to this heat stress due to its monsoon and high pre-monsoon temperatures. However, human-related factors worsen this situation, such as urban development and diminishing green cover.

Some experts, however, are saying that the ongoing heatwave is not an El Niño; rather, it is an anti-cyclonic pressure over northern and central India, which is working like a heat dome. However, the possibility of a stronger El Niño cannot be completely ruled out. Previously, it occurred in 1997–1998 and 2015–2016, resulting in drought-like conditions.

Can the heatwave trigger heart attacks?

In an interview with Health and Me, Dr Joy Shome, Head of TAVI/TAVR at CK Birla Hospitals, BM Birla Heart Hospitals, said, "An alarming rise in the number of young adults who experience cardiac events has been observed due to heatwaves that are becoming more common and more extreme (as outlined in the Beat by Beat report). The cardiovascular system is put under enormous strain by excessive amounts of heat. To help cool down the body, our blood vessels expand (dilate), and the heart must pump more blood through them; however, dehydration results in thicker blood, increasing your chance of developing a blood clot (a leading cause of heart attacks)."

Dr Shome also said that heart disease is no longer only affecting the elderly; a substantial number of cardiac deaths occur prematurely and affect younger populations. Lifestyle, stress, and metabolic issues are all contributors to this trend. India has contributed nearly one in five cardiac deaths worldwide, and cardiovascular disease accounts for around 25% of all deaths in India—illustrating how large this crisis is. The ‘thin fat’ phenomenon is another factor; many Indian people may look thin but have significant amounts of visceral fat — meaning many young adults could be at risk of suffering a heart attack.

Is the heatwave making people in India fall sick?

States and Union Territories have been instructed by the Ministry of Health and Family Welfare to create heatwave management units, issue early warnings, and maintain real-time reporting of heatstroke cases. These measures, however, may not be enough, especially for vulnerable groups of people. Severe heatwaves can lead to death, yes; however, there is a risk of heat stress, heatstroke, and even dehydration.

In an interview with Health and Me, Dr Manjusha Agarwal, Consultant - Internal Medicine, Gleneagles Hospital Mumbai, spoke about the possible effects of a Super El Niño on health. The expert spoke about whether or not it is this heatwave that is making people in India fall sick.

A potential Super El Niño is known to intensify heatstroke and can place a significant stress on the heart. So, the impact can be directly seen on the cardiovascular system during the scorching heat. Not only this, many people may also experience dehydration and heatstroke or even respiratory illnesses and vector-borne diseases like dengue and malaria. So, everyone needs to be cautious and prioritise heart health. When temperatures rise, the body tries to cool itself by increasing blood flow to the skin, which tends to stress the heart.

Dr Agarwal went on to say that constant sweating during summer leads to fluid and electrolyte loss, making the blood thicker, and there can be chances of clotting. This can raise the chances of heart attacks or strokes, mainly in those with a history of pre-existing conditions such as hypertension, diabetes, or heart disease. They may experience concerning symptoms like dizziness, fatigue, or palpitations, which are neglected by many people.

So, when there is scorching heat outside, it is necessary for everyone to stay hydrated by drinking 2-3 litres of water, maintain electrolyte balance, avoid peak heat hours that are from 12:00 pm to 5:00 pm, and take medication prescribed by the doctor. Everyone should be aware when it comes to heart health and overall well-being. Hence, it is time to follow these vital types and protect the heart during intense heat.

The infant formula available on the US market is safe, according to results from the largest and most rigorous study by the Food and Drug Administration (FDA), released today.

Breast milk is widely known as the gold standard and optimal source of nutrition for infants whenever possible. However, as per the CDC, roughly 75 per cent of US infants are dependent on formula for the first six months, and for nearly 40 per cent, it is the exclusive source of nutrition.

The FDA noted that across 300 samples tested, an overwhelming majority had undetectable or very low levels of contaminants, affirming that the US infant formula supply is safe. But the federal agency plans to follow up with additional testing.

“We tested more infant formula than ever before, and the results are clear: most products meet a high safety standard—but even small exposures matter for newborns,” said Health and Human Services Secretary Robert F. Kennedy, Jr., in a statement.

“We will hold manufacturers accountable and give parents honest, transparent data they can trust. Protecting our children’s health is nonnegotiable," he added.

How Was The Study Conducted?

The study included more than 300 infant formula samples representative of products sold at retail across the US and included powders, ready-to-feed liquids, and concentrated liquids.

The samples were rigorously tested and analyzed in FDA laboratories. The results show that the overall levels of contaminants in the infant formula samples tested were low.

However, the FDA noted that it is following up with additional testing as part of the agency’s ongoing robust monitoring and oversight efforts and will take additional action where appropriate.

This includes conducting further testing, including for additional contaminants, continuing to engage with manufacturers on measures to reduce the levels of contaminants to as low as possible, and working to establish action levels for contaminants in infant formula.

“You can judge a society by how it treats its most vulnerable members. That’s why we’re doing everything in our power to make sure our babies and infants have safe, high-quality formula options that are backed by a resilient supply chain,” said FDA Commissioner Marty Makary.

“The results of this study are encouraging. We will continue to advance formula innovation and safety for the millions of families who depend on it.”

Why Was The Baby Formula Tested?

Formula is made to imitate human breast milk and usually comes from cow milk or soy. According to the present FDA guidelines, every infant formula product is required to have 30 nutrients essential for infants in specific proportions.

Yet, the technology of infants' digestion and nutrition requirements has progressed immensely, leading experts to wonder if the standards are yet sufficient.

In 2025, the FDA in 2025 began conducting a comprehensive review of infant formula ingredients in the face of increasing parental distrust and industry trends, which indicate that existing rules might not be completely in accordance with recent worldwide research on infant feeding.

Some of the main issues that were considered during the testing include the possibility of iron content, added sugars, and seed oils.
