Many diseases share the same symptoms, causing people to get confused and either undermine or overwhelm themselves with worries. With the current flu season on the rise, people in the United States are being very careful about their health and are taking necessary precautions to make sure they do not catch any more respiratory illnesses. Often these diseases show symptoms like coughing and wheezing, nothing that warrants anything more than a general doctor’s visit, sometimes people even think it it is a simple cold, but it could be something worse!

The Centers For Disease Control and Prevention (CDC) report on 28 February, last Friday on Respiratory Virus Activity Levels reported a moderate number of people are seeking medical help for respiratory illnesses. The flu is sending many people to the emergency room, RSV Respiratory syncytial virus has been sending many people to the ER along with COVID-19.

While flu test results are slightly less positive than last week, COVID-19 and RSV test results are about the same. In our community's wastewater, the flu virus is still very high, COVID-19 is moderate, and RSV is low. Looking forward, we expect COVID-19 emergency room visits to stay low. While flu visits are still high, they should start to go down soon.

So, even though it might feel like winter is ending, these viruses are still active, and we need to be careful. They are not going away quickly and can still spread easily. Here are some symptoms that should be treated with urgency right now.

Severe Dehydration

When you're really sick, you might not feel like eating or drinking. This can lead to dehydration, which is when your body doesn't have enough water. If your pee is dark yellow, or you feel dizzy, you might be dehydrated. If you pass out, get confused, or your heart beats really fast, you need to go to the hospital right away. Healthcare professionals can give you fluids through a needle to help you feel better. Being dehydrated is very dangerous, and it is important to take it seriously.

Breathing Difficulties

If you're having trouble breathing, or if you're breathing really fast, that's a big sign. It could mean that you have pneumonia or that your body isn't getting enough oxygen. Shortness of breath is always a reason to go to the emergency room. Your body is telling you that something is seriously wrong. It is very important to seek help right away. Do not wait it out at home.

Low Oxygen Levels

If your lips or fingers start to turn blue, that means you're not getting enough oxygen. Also, if you're so tired that you can barely get out of bed, that's another sign that you need to go to the hospital. These are serious symptoms that mean your body needs help right away.

Who’s Most at Risk for Severe Symptoms?

Some people are more likely to get very sick from these viruses. Pregnant people, little kids, and older adults are at higher risk. Also, people who have health problems like heart or lung disease, or people with weak immune systems, are more likely to have serious problems. Older adults are often hospitalized with the flu, COVID, and RSV. These groups need to be extra careful to avoid getting sick. It is very important that these groups get vaccinated.

RSV is especially dangerous for babies and young children. It's one of the main reasons why young kids end up in the hospital. This virus can make it very hard for them to breathe. It is very important to protect young children from this virus, especially in the first few years of their lives.

Climate change is increasingly emerging as a major public health threat, contributing to a growing burden of disease worldwide and creating favorable conditions for the spread of infectious illnesses, according to health experts on World Environment Day 2026.

World Environment Day is observed every year on June 5 to raise awareness about the need for immediate action as heatwaves intensify, air pollution worsens, ecosystems degrade, and climate anxiety grows worldwide, even as the world crosses the UN-mandated 1.5°C limit.

The theme for World Environment Day 2026 is "Inspired by Nature. For Climate. For Our Future". It focuses on climate change and the signals nature is sending such as rising seas, raging wildfires, heatwaves and melting glaciers.

To understand the intersection between climate change and health impacts, HealthandMe spoke to two experts.

Heatwaves, Pollution And Food Insecurity

According to Dr. Sabine Kapasi, UN advisor, the consequences are no longer limited to environmental damage. Rising temperatures, worsening air pollution and shifting weather patterns are already affecting human health across the globe.

“Longer and more intense heatwaves are resulting in more cases of heat-related illness. Air pollution continues to exacerbate respiratory diseases, while changing weather patterns are impacting food security and nutrition in many parts of the world,” she said.

Importantly, in India, children, pregnant women and communities living in flood- and drought-prone regions face some of the greatest risks. Women are often disproportionately affected due to challenges related to water supply and sanitation. While India has reduced malaria cases by nearly 80 per cent since 2015, climate change is creating new health challenges that health systems will need to address in the coming years.

Infectious Disease Outbreaks

The expert warned that changing climatic conditions are also increasing the risk of infectious disease outbreaks. Dr. Kapasi told HealthandMe that rising temperatures and altered rainfall patterns are allowing mosquitoes to breed more easily and remain active for longer periods.

Floods further compound the problem by contaminating drinking water, damaging sanitation systems and disrupting healthcare services. Displacement caused by disasters can force families into crowded living conditions, increasing the risk of infections such as cholera, leptospirosis and tuberculosis.

“Recent climate-related disasters in South Asia and Africa have shown how quickly an environmental crisis can turn into a public health challenge,” she noted.

The spread of mosquito-borne diseases such as dengue, malaria and chikungunya is also becoming a growing concern. Health authorities around the world are reporting these diseases in areas where they were previously uncommon.

Globally, countries including Italy, France and Spain have also witnessed an increase in locally transmitted dengue and chikungunya cases over the past decade. In the United States, locally acquired malaria cases were recently reported in Florida and Texas, marking the first such transmission in nearly 20 years.

India is also experiencing rising dengue activity. Dengue outbreaks have become a regular occurrence during the monsoon and post-monsoon seasons in many states. Estimates suggest dengue cases could reach around 278,000 in 2025, up from roughly 230,000 the previous year. Experts say warmer temperatures and changing rainfall patterns are helping disease-carrying mosquitoes survive and spread more effectively.

Climate Change And Shifting Disease Patterns

Dr. Devarsetty Praveen, Program Director at NIHR GHRC for Non-communicable Diseases and Environmental Change, hosted by The George Institute India, in partnership with Imperial College London, said climate change is affecting both communicable and non-communicable diseases.

“Climate change is increasing health risks through rising temperatures, extreme weather events, worsening air quality and changing disease patterns. In India, it is affecting both communicable and non-communicable diseases, with vulnerable populations bearing the greatest burden,” he told HealthandMe.

He noted that research has found that people living with chronic conditions such as hypertension and diabetes are particularly vulnerable to extreme heat, underscoring the growing link between climate change and non-communicable diseases.

Dr. Praveen added that climate change influences disease transmission by altering temperature, humidity and rainfall patterns while also affecting water quality, food systems and interactions between humans, animals and disease vectors.

“These changes can make outbreaks more frequent, more widespread and harder to predict,” he said.

How To Reduce Climate-related Health Risks

To reduce climate-related health risks, the experts recommend staying informed about weather conditions, remaining hydrated, limiting outdoor exposure during extreme heat and taking precautions against mosquito bites.

People with chronic conditions such as hypertension, diabetes, heart disease and kidney disease are advised to maintain adequate medication supplies and consult healthcare providers during periods of extreme heat.

According to the experts, awareness and early action remain critical to protecting public health as climate change continues to reshape disease patterns around the world.

To reduce the risk of mosquito-borne diseases, people should make sure that water does not get collected in buckets, coolers, flower pots or other containers around the home. Additional precautions include the use of mosquito repellents, sleeping under nets when necessary and wearing clothing that covers the arms and legs.

Dr Sabine said food and water safety is particularly important after heavy rain or flooding. Proper food storage, clean drinking water and good hygiene practices can go a long way in preventing many infections. Those with pre-existing medical conditions should also have essential medicines within easy reach during extreme weather.

The United States has been working on reducing smog for more than a decade and has become quite successful in this endeavor, but since 2015, the situation has changed for the worse as a new study reveals that the smog level is once again on the rise, and the main reason behind this is another long-term problem of the nation, wildfire.

The federal regulations tightened on power plants, cars, and diesel engines, which in turn caused a drop in the national smog level by 11% from 2003 to 2015. Since then, cases of wildfire have increased, resulting in the smog level going up by 4%. The study finds that if the current trend continues, it will cause smog to go back up to 2003 levels in 20 years.

The study in the journal Science has also calculated a surge in deaths from ozone attacking lungs by comparing death rates in clean and dirty air. They estimated a surge of 318 American deaths per year since 2013 due to smog.

The co-author of the study, Meng Zhou, a University of Iowa wildfire researcher, said, “For the last 20 years, by regulations, we keep decreasing the emissions." He added, “However, because of wildfires, which are actually from natural hazards, all those kinds of effort were wiped out.”

The study also flagged concerns about the current smog situation and its possible impact on the population. University of Washington public health and climate scientist Kristie Ebi said, “Higher daily ozone concentrations can increase asthma attacks, hospital admissions, and mortality.” She added, “still a very important pollutant, which is why it's regulated.”

The research finds that the heavy wildfire smoke seasons of 2022, 2023, and 2024, mainly in Canada, created a massive amount of smog, and this then came down south. As a result, about 43 million people got exposed to smog levels that exceeded the current EPA safety standards. The wildfires in Canada have been particularly severe since 2022.

The problem is also with the massive wildfires in the mainland US, as the National Interagency Fire Center's data also shows that the average amount of land in the US that wildfires burn every year has increased by 9% higher than it was from 2003 to 2014.

What Are The Possible Health Impacts?

There are many short-term and long-term impacts on public health from the constant exposure to air pollution. As per IQAir, in the short term, people experience irritation in the eyes, throat, and nose, along with irregular heartbeats, asthma attacks, coughing, chest tightness, and difficulty breathing.

Prolonged exposure also intensifies these risks and leads to long-term effects such as chronic respiratory illnesses like bronchitis, asthma, and emphysema. Pollutants can also damage lung tissue, increasing the likelihood of lung cancer. Air pollution also leads to an increased risk of heart attacks and strokes, and could also be linked to premature death.

Naturopath and health educator Barbara O'Neill believes many of the foundations of good health are simple, inexpensive, and often overlooked.

In an interview with HealthandMe, she spoke about her journey into natural healing. Barbara said her interest began when she was looking for alternatives to repeated medication use for her children.

"I was pulled towards natural healing because I didn't want to give my children drugs," she said, recalling how her first child underwent four courses of antibiotics within six weeks.

That experience prompted her to explore other ways of managing common health issues such as earaches and discomfort.

On Ayurveda And Traditional Healing

Barbara said she sees similarities between her philosophy of health and Ayurveda. "I believe that there's a lot of similarities between what I believe," said the 72-year-old, adding that she supports approaches that work and do not cause harm.

While acknowledging that medicines can save lives in emergencies, she argued that long-term healing depends on creating the right conditions for the body.

"Yes, in a crisis, a drug may save a life, but drugs can't heal us. That's why it's time to go back to the old ways," she said.

According to Barbara, understanding how the body functions is key to understanding healing.

"When you understand how they function, then you begin to understand what they need. And if you give the body the right conditions, the healing will accelerate," she told HealthandMe.

The Healthy Habits

Barbara said that sleep, hydration, exercise, and natural foods are key to better health. She also called out modern lifestyles, which often encourage people to stay awake too late, particularly because of technology; and recommended getting enough sleep.

"Start going to bed earlier and aiming for eight hours sleep a night," she said.

Barbara also emphasized daily movement, whether through running, walking, push-ups, squats, or stretching.

"Every day, I make a point of moving my body," she said.

Why Barbara O'Neill Doesn't Take Supplements

At a time when supplements have become a multi-billion-dollar industry, Barbara revealed that she does not take any supplements herself.

"I take no supplements," she said, noting that she advocates focusing on fundamental health habits.

"What should be there instead is exercise every day, eating food in its natural state, drinking adequate water, and going to bed early," she said.

While she is not opposed to supplements, she believes they are often unnecessary.

"There are times where they may be necessary, but most of the time we don't need them," she added.

Natural Food And Stress Management

Barbara also encouraged people to eat foods in their natural state and suggested a simple dietary habit for Indians.

"Eat dal every day," she said.

For stress management, she said both sleep and meditation are important. She described beginning each day with prayer, reflection, and quiet time.

Barbara said that the human body has an innate ability to heal when supported by healthy habits.

"I want people to remember that they live in a body that can heal. So please look after it," she told HealthandMe.
