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.

Importance of Hydration for Organs: How Water Keeps the Body Functioning

Water is the most essential nutrient for human survival, yet it is often the most neglected. Every cell, tissue and organ in the body depends on adequate hydration to function properly. The importance of hydration for organs becomes clear when we understand how even mild dehydration can disrupt critical physiological processes.

In India’s climate, with high temperatures and humidity in many regions, dehydration risk is especially high, making conscious hydration a daily health priority.

 

Why Water Is Vital for the Human Body

The human body is made up of approximately 60 percent water. This water:

  • transports nutrients and oxygen
     

  • regulates body temperature
     

  • removes waste products
     

  • supports metabolic reactions
     

Without adequate hydration, organ systems begin to struggle.

 

Hydration and Kidney Health

The kidneys are among the most hydration-dependent organs.

Proper hydration:

  • helps kidneys filter blood efficiently
     

  • flushes out toxins and waste
     

  • reduces risk of kidney stones
     

Chronic dehydration forces kidneys to concentrate urine, increasing strain and long-term damage risk. According to Indian Council of Medical Research data, dehydration is a major contributor to kidney stone formation in India.

 

Brain Function and Hydration

The brain is highly sensitive to hydration levels.

Even mild dehydration can cause:

  • headaches
     

  • difficulty concentrating
     

  • memory issues
     

  • irritability
     

Studies published in the Lancet show that dehydration negatively affects cognitive performance and mood, even before thirst becomes noticeable.

 

Heart and Circulatory System

Hydration plays a critical role in cardiovascular health.

Adequate water intake:

  • maintains blood volume
     

  • supports smooth circulation
     

  • reduces strain on the heart
     

Dehydration thickens blood, making the heart work harder and potentially increasing the risk of low blood pressure, dizziness and cardiovascular stress.

 

Digestive System and Hydration

Water supports digestion at every stage.

It helps:

  • break down food
     

  • absorb nutrients
     

  • prevent constipation
     

Chronic low water intake is linked to digestive discomfort, bloating and poor gut motility.

 

Liver Function and Detoxification

The liver relies on water to:

  • metabolise nutrients
     

  • detoxify harmful substances
     

  • support metabolic balance
     

Inadequate hydration slows detoxification processes and increases metabolic strain.

 

Muscle and Joint Health

Muscles and joints contain significant water content.

Hydration:

  • prevents muscle cramps
     

  • supports joint lubrication
     

  • reduces injury risk
     

Dehydrated muscles fatigue faster and recover more slowly.

 

Skin as an Organ and Hydration

The skin is the body’s largest organ.

Adequate hydration:

  • maintains skin elasticity
     

  • supports barrier function
     

  • reduces dryness and irritation
     

While water alone is not a cure for skin problems, chronic dehydration worsens skin health.

 

Hydration and Immune Function

Water supports immune health by:

  • enabling transport of immune cells
     

  • aiding removal of toxins
     

  • supporting lymphatic circulation
     

WHO recognises hydration as a foundational element of immune system support.

 

Effects of Dehydration on Multiple Organs

Dehydration affects the body systemically.

Common effects include:

  • fatigue
     

  • dizziness
     

  • reduced urine output
     

  • dark-coloured urine
     

  • dry mouth and eyes
     

Severe dehydration can lead to organ failure if untreated.

 

Why Dehydration Often Goes Unnoticed

Many people confuse thirst with hunger or fatigue.

Risk factors include:

  • busy work schedules
     

  • excessive caffeine intake
     

  • high temperatures
     

  • inadequate fluid intake
     

By the time thirst is felt, dehydration has already begun.

 

Hydration Needs Vary by Individual

Water requirements depend on:

  • age
     

  • body size
     

  • physical activity
     

  • climate
     

  • health conditions
     

General guidelines suggest 2–3 litres daily for adults, but individual needs may vary.

 

Hydration and Chronic Disease Prevention

Proper hydration supports prevention of:

  • kidney disease
     

  • urinary tract infections
     

  • constipation
     

  • heat-related illness
     

NITI Aayog and WHO highlight hydration as a basic preventive health measure.

 

Best Practices for Staying Hydrated

Effective hydration strategies include:

  • drinking water regularly throughout the day
     

  • increasing intake during heat or physical activity
     

  • consuming water-rich foods such as fruits and vegetables
     

  • limiting sugary and caffeinated beverages
     

Consistency matters more than quantity in a single sitting.

 

Signs You May Need More Water

Watch for:

  • frequent fatigue
     

  • headaches
     

  • dry skin
     

  • reduced urination
     

  • poor concentration
     

These are early indicators of dehydration.

 

Role of Preventive Health Awareness

Preventive healthcare focuses on simple daily habits.

Hydration:

  • costs nothing
     

  • supports every organ
     

  • reduces disease risk
     

Small habits deliver large long-term benefits.

 

When to Seek Medical Advice

Consult a healthcare professional if experiencing:

  • persistent dehydration symptoms
     

  • kidney or urinary issues
     

  • dizziness or fainting
     

  • chronic fatigue
     

Underlying conditions may require medical evaluation.

 

Conclusion

The importance of hydration for organs cannot be overstated. Water supports kidney filtration, brain function, heart circulation, digestion, immunity and overall metabolic balance. Even mild dehydration disrupts organ performance and increases health risks over time. In busy modern lifestyles, consciously prioritising daily hydration is one of the simplest and most effective ways to protect vital organs and maintain long-term health. Consistent water intake is not just a habit—it is a foundation for organ health and wellbeing.
