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.

How Cold Weather Affects Health: Understanding Winter’s Impact on the Body

How Cold Weather Affects Health: Understanding Winter’s Impact on the Body

Seasonal changes influence human health more than most people realise. Cold weather, in particular, places unique stress on the body and can worsen existing health conditions while increasing susceptibility to new illnesses. Understanding how cold weather affects health is essential for preventing seasonal complications and maintaining wellbeing during winter months.

In India, winter-related health issues vary by region but commonly include respiratory infections, cardiovascular strain and joint discomfort. According to the Indian Council of Medical Research (ICMR) and World Health Organization (WHO), cold exposure is associated with increased morbidity, especially among older adults and people with chronic conditions.

 

Why Cold Weather Impacts the Body

The human body works constantly to maintain core temperature. In cold environments:

  • blood vessels constrict to conserve heat
     

  • energy expenditure increases
     

  • immune responses may weaken
     

  • organs work harder to maintain balance
     

These adaptations, while protective, also create health vulnerabilities.

 

Increased Risk of Infections

Weakened Immune Response

Cold weather can suppress immune function, making it harder for the body to fight infections.

Factors contributing to winter infections include:

  • reduced vitamin D due to less sunlight
     

  • dry air affecting mucosal defenses
     

  • closer indoor contact
     

Common winter infections include colds, flu and respiratory illnesses.

 

Respiratory Health Problems

Cold air irritates the respiratory tract.

This can lead to:

  • worsening asthma symptoms
     

  • bronchitis flare-ups
     

  • increased cough and breathlessness
     

WHO reports higher hospital admissions for respiratory illnesses during colder months.

 

Impact on Heart Health

Cold temperatures affect cardiovascular function.

Blood Vessel Constriction

Cold causes blood vessels to narrow, increasing:

  • blood pressure
     

  • heart workload
     

This raises the risk of:

  • heart attacks
     

  • strokes
     

People with existing heart disease are particularly vulnerable.

 

Joint and Muscle Pain

Cold weather affects musculoskeletal health.

Common complaints include:

  • joint stiffness
     

  • muscle aches
     

  • worsening arthritis pain
     

Lower temperatures reduce joint lubrication and increase sensitivity to pain.

 

Metabolic and Weight Changes

Winter often leads to:

  • reduced physical activity
     

  • increased calorie intake
     

  • metabolic slowdown
     

These changes contribute to weight gain and worsen metabolic conditions such as diabetes.

 

Skin and Hydration Issues

Cold air holds less moisture.

This leads to:

  • dry skin
     

  • cracked lips
     

  • worsening eczema
     

Dehydration is also common as thirst perception reduces in cold weather.

 

Mental Health Effects

Seasonal changes can influence mental wellbeing.

Cold weather is associated with:

  • low mood
     

  • reduced motivation
     

  • seasonal affective symptoms
     

Limited sunlight affects circadian rhythm and serotonin levels.

 

Cold Weather and Older Adults

Elderly individuals face higher risks due to:

  • reduced temperature regulation
     

  • weaker immunity
     

  • existing chronic conditions
     

Winter-related complications are a significant cause of hospitalisation in older populations.

 

Why Chronic Diseases Worsen in Winter

Conditions such as:

  • hypertension
     

  • arthritis
     

  • asthma
     

  • diabetes
     

often worsen due to reduced activity, stress on organs and infection risk.

 

Preventive Strategies for Winter Health

Maintain Body Warmth

Layered clothing and warm environments reduce cold stress.

 

Support Immunity

Adequate nutrition, vitamin intake and sleep strengthen immune defences.

 

Stay Physically Active

Indoor exercises and regular movement prevent stiffness and metabolic decline.

 

Manage Chronic Conditions

Regular monitoring and medication adherence are critical during winter.

 

Hydration and Skin Care

Drinking fluids and using moisturisers prevent dehydration and skin damage.

 

Role of Preventive Healthcare

Preventive healthcare helps:

  • identify seasonal risk factors
     

  • adjust treatment plans
     

  • prevent winter complications
     

NITI Aayog highlights seasonal preparedness as an important public health strategy.

When to Seek Medical Help

Medical attention is necessary if:

  • infections persist or worsen
     

  • chest pain or breathlessness occurs
     

  • joint pain limits mobility
     

  • mental health symptoms interfere with daily life
     

Early care prevents serious outcomes.

 

Long-Term Impact of Ignoring Winter Health Risks

Ignoring cold weather effects may lead to:

  • severe infections
     

  • cardiovascular events
     

  • chronic pain progression
     

  • reduced quality of life
     

Seasonal awareness plays a critical role in long-term health.

 

Conclusion

Understanding how cold weather affects health allows individuals to take timely preventive measures. Winter increases the risk of infections, heart strain, respiratory problems, joint pain and mental health challenges. With proper warmth, nutrition, activity and preventive healthcare, most cold-related health issues are manageable and preventable. Seasonal care is not optional—it is essential for protecting health and wellbeing throughout the colder months.
