MYTHBUSTER

There are many rumours, theories and suggestions that are being spread on Facebook, WhatsApp and social media. Most of these have no truth to them, do not work as treatment, or can be dangerous to your health. They use language that makes them sound scientific, and usually claim to come from a reputable institute, medical journal or doctor. Many people will automatically trust this, without questioning whether the legitimacy of the advice given. We have covered the dangers of these social media posts in our blog: https://www.secondmedic.com/blogs/the-dangers-of-social-media-blind-forwards secondmedic blog

Here we will go over some common myths about COVID-19 and Coronavirus that you will encounter. If you have come across any new myths or theories, or you want to check something you have read or been sent, email us at info@secondmedic.com

5G mobile networks DO NOT spread COVID-19

This is a myth that has been spreading recently, claiming that the new 5G towers being erected are spreading COVID-19. This is not true and there is no scientific evidence to support this.

Coronavirus spreads on small droplets that are coughed up by infected people. It is possible to prove this by looking at these droplets under an electron microscope. 5G networks use radio waves to operate, similar to 4G networks and other mobile network technologies. Radio waves cannot carry or transmit viral particles.

Another theory is that 5G radio waves cause damage to the human body. Radio waves have very little energy and pass through the human body without causing any harm. They have less energy than sunlight, and we are exposed to sunlight daily without harm.

People are claiming that 5G and coronavirus arrived at the same time, and so must be connected. Simply linking two things together does not mean one causes another. 5G technology does not exist in many countries with COVID-19, and yet some of these countries have been hit harder than well developed countries.

Destroying masts because of this conspiracy theory is harmful, as these masts carry mobile network signals that allow people to phone in emergencies, and for emergency responders to communicate with hospitals, fire stations and the police. Destroying these masts can cause serious harm to others.

Coronavirus WAS NOT developed in a laboratory as a weapon by China/Russia/US

Multiple reputable labs and universities across the world have analysed the coronavirus responsible for COVID-19, and have determined there is no evidence it was produced by humans. It is very similar to pre-existing coronaviruses that have caused the SARS and MERS pandemics. Conspiracy theories such as these are being used to shift the blame to others and gain political points in the news, rather than focus on what is important – preventing the spread of the virus and treating those that are ill.

Holding your breath for 10 seconds or more without coughing DOES NOT prove you are free of COVID-19

One popular test that has spread on WhatsApp states you can see whether you have COVID-19 with one simple test. If you can hold your breath for more than 10 seconds without coughing or feeling any discomfort, you do not have COVID-19 and are safe. It says that COVID-19 causes fibrosis in your lungs and this can stop you from holding your breath. There is no evidence supporting this theory.

Many people who have had COVID-19 can hold their breath for 10 seconds, and many people who are virus free are unable to hold their breath. The only way to determine if you have had the virus is through a nose or throat swab to check for the virus. If you have symptoms of COVID-19 (fever, dry cough, feeling tired, shortness of breath), you should assume you have the virus and isolate yourself.

Drinking alcohol DOES NOT protect you against COVID-19

Alcohol is a disinfectant. Washing your hands with alcohol based hand gels can destroy the bacteria. However drinking alcohol is not the same. When you drink alcohol it is processed by your body to release energy, and it loses its disinfectant properties. Drinking too much alcohol can cause alcohol poisoning and damage your liver.

Hundreds of people have died as a result of drinking methanol, a dangerous form of alcohol.

Spraying alcohol over your body will kill any virus that is on your skin. But you should only use alcohol based hand gels, as they have the right amount of alcohol that does not harm your skin. Alcohol based gels will not cure COVID, as the virus causing the symptoms is in your lungs, not your skin.

Drinking bleach DOES NOT protect you against COVID-19. IT CAN KILL YOU

Just like alcohol, disinfectants and bleach can kill the virus if sprayed onto a surface that has the virus. But drinking them is highly dangerous and can be lethal. If ingested bleach will destroy your stomach just like it destroys the virus, and it will continue to destroy your body depending on how much is ingested.

DO NOT DRINK BLEACH.

Similarly do not spray disinfectant or bleach on your skin. It is  highly irritating and can cause a lot of damage, especially if it gets in your eyes, nose or mouth.

Asthma

Asthma Symptoms in Adults: Early Signs, Triggers, and When to Seek Care

Asthma is often perceived as a childhood condition, but a significant number of cases develop or persist into adulthood. In India, adult asthma is increasingly recognised due to rising air pollution, occupational exposure and lifestyle-related risk factors. Unfortunately, asthma symptoms in adults are frequently misdiagnosed as recurrent infections, allergies or age-related breathlessness, leading to delayed treatment.

Understanding adult asthma symptoms is critical for early diagnosis, effective control and prevention of severe attacks.

 

What Is Asthma?

Asthma is a chronic inflammatory disease of the airways. In asthma, the airways become:

  • inflamed
     

  • narrow
     

  • overly sensitive to triggers
     

This leads to difficulty in breathing, especially during exposure to specific stimuli.

 

Why Adult Asthma Is Often Missed

Adult asthma symptoms may:

  • appear gradually
     

  • vary in severity
     

  • mimic common respiratory conditions
     

According to Indian Council of Medical Research and WHO data, many adults remain undiagnosed for years, increasing the risk of complications.

 

Common Asthma Symptoms in Adults

Wheezing

A high-pitched whistling sound while breathing, especially during exhalation, is a classic asthma sign.

 

Shortness of Breath

Adults with asthma often feel:

  • breathless during routine activities
     

  • difficulty taking deep breaths
     

This may worsen at night or early morning.

 

Chest Tightness

Many describe a sensation of pressure or tightness in the chest, which can be mistaken for heart-related issues.

 

Chronic Cough

A persistent cough, especially:

  • at night
     

  • early morning
     

  • after exercise
     

is a common but overlooked asthma symptom.

 

Symptoms That Worsen With Triggers

Asthma symptoms often intensify after exposure to specific triggers.

Air Pollution and Smoke

Urban pollution, vehicle emissions and indoor smoke significantly worsen asthma symptoms in adults.

 

Allergens

Dust mites, pollen, mould and pet dander are common triggers.

 

Respiratory Infections

Viral infections can trigger asthma flare-ups or reveal undiagnosed asthma.

 

Physical Activity

Exercise-induced asthma causes breathlessness and wheezing during or after physical exertion.

 

Weather Changes

Cold air, humidity and sudden temperature changes can aggravate symptoms.

 

Adult-Onset Asthma

Adult-onset asthma differs from childhood asthma.

Characteristics include:

  • onset after age 20–30
     

  • less association with childhood allergies
     

  • more persistent symptoms
     

  • higher likelihood of severe disease
     

Occupational exposure and hormonal changes contribute to adult-onset asthma.

 

Risk Factors for Asthma in Adults

Several factors increase asthma risk:

  • long-term exposure to pollution
     

  • smoking or passive smoking
     

  • occupational chemicals or dust
     

  • obesity
     

  • family history of asthma
     

  • chronic sinusitis or allergies
     

Women may experience asthma onset or worsening during hormonal changes.

 

When Asthma Symptoms Become Serious

Seek immediate medical attention if experiencing:

  • severe breathlessness
     

  • difficulty speaking in full sentences
     

  • bluish lips or fingertips
     

  • rapid worsening of symptoms
     

  • poor response to usual inhalers
     

These signs indicate a potentially life-threatening asthma attack.

 

How Adult Asthma Is Diagnosed

Diagnosis includes:

  • detailed symptom history
     

  • physical examination
     

  • lung function tests (spirometry)
     

  • response to bronchodilators
     

Early diagnosis improves long-term outcomes.

 

Impact of Untreated Asthma

Untreated asthma can lead to:

  • frequent attacks
     

  • reduced lung function
     

  • sleep disturbances
     

  • missed workdays
     

  • reduced quality of life
     

According to Lancet respiratory studies, uncontrolled asthma increases hospitalisation risk.

 

Managing Asthma Symptoms in Adults

Effective asthma management focuses on:

  • identifying and avoiding triggers
     

  • using prescribed inhalers correctly
     

  • monitoring symptoms regularly
     

  • maintaining follow-up care
     

Asthma action plans help patients recognise worsening symptoms early.

 

Role of Preventive Healthcare

Preventive healthcare helps:

  • detect asthma early
     

  • assess lung function
     

  • guide lifestyle modifications
     

Regular health checkups are especially important for individuals with respiratory symptoms or occupational exposure.

 

Lifestyle Measures That Support Asthma Control

Helpful practices include:

  • avoiding smoking
     

  • improving indoor air quality
     

  • wearing masks in polluted environments
     

  • maintaining healthy weight
     

  • regular, moderate exercise
     

Lifestyle support complements medical treatment.

 

Mental Health and Asthma

Stress and anxiety can worsen asthma symptoms.

Stress management:

  • reduces symptom frequency
     

  • improves medication response
     

Holistic care improves asthma outcomes.

 

Importance of Medication Adherence

Asthma medications work best when:

  • taken regularly as prescribed
     

  • inhaler technique is correct
     

Skipping treatment increases flare-up risk.

 

Long-Term Outlook for Adults With Asthma

With proper management:

  • symptoms are well controlled
     

  • severe attacks are preventable
     

  • normal activity levels are achievable
     

Most adults with asthma lead active, productive lives.

 

Conclusion

Asthma symptoms in adults are often subtle, variable and easily mistaken for common respiratory problems. Wheezing, breathlessness, chest tightness and chronic cough should not be ignored, especially when triggered by pollution, exercise or weather changes. Early diagnosis, trigger control and consistent treatment are essential to prevent severe attacks and preserve lung health. Recognising adult asthma early empowers individuals to manage symptoms effectively and maintain a good quality of life.
