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.

Sleep Debt and Its Impact on the Body: Hidden Risks of Chronic Sleep Loss

Sleep is not a luxury; it is a biological necessity. Yet in today’s fast-paced world, many people consistently sacrifice sleep due to work demands, screen time and stress. Over time, insufficient sleep accumulates into what is known as sleep debt. Understanding sleep debt and its impact on the body is essential because chronic sleep loss silently affects nearly every organ system.

According to the World Health Organization and global sleep research, chronic sleep deprivation is associated with increased risk of cardiovascular disease, metabolic disorders and mental health conditions.

 

What Is Sleep Debt?

Sleep debt refers to the cumulative effect of not getting enough sleep.

For example:

  • if you need 8 hours but sleep 6 hours daily

  • you accumulate 2 hours of sleep debt per night

Over a week, that equals 14 hours of lost sleep.

This deficit places strain on the body.

 

Why Sleep Is Critical for Health

Sleep supports:

  • brain function

  • immune response

  • hormonal regulation

  • tissue repair

  • memory consolidation

Without adequate sleep, these processes become impaired.

 

Immediate Effects of Sleep Debt

Short-term consequences include:

  • daytime fatigue

  • poor concentration

  • mood swings

  • irritability

  • reduced reaction time

Even one night of poor sleep affects cognitive performance.

 

Sleep Debt and Hormonal Imbalance

Sleep regulates several key hormones.

Chronic sleep loss disrupts:

  • cortisol

  • insulin

  • leptin and ghrelin (hunger hormones)

This imbalance affects appetite, stress and metabolism.

 

Impact on Metabolic Health

Sleep debt increases:

  • insulin resistance

  • blood sugar fluctuations

  • abdominal fat accumulation

ICMR and NFHS-5 data show rising metabolic disorders in India, partly linked to lifestyle patterns including poor sleep.

 

Increased Risk of Obesity

When sleep is insufficient:

  • appetite hormones increase

  • cravings for high-calorie foods rise

  • impulse control weakens

Sleep deprivation promotes weight gain.

 

Sleep Debt and Immunity

The immune system relies heavily on sleep.

Chronic sleep loss:

  • reduces infection-fighting cells

  • increases inflammation

  • slows recovery from illness

Lancet research confirms that sleep deprivation weakens immune response.

 

Cardiovascular Consequences

Sleep debt increases risk of:

  • hypertension

  • heart disease

  • stroke

Poor sleep affects blood pressure regulation and vascular health.

 

Mental Health Impact

Sleep and mental health are deeply connected.

Sleep debt contributes to:

  • anxiety

  • depression

  • emotional instability

Chronic insomnia is both a cause and consequence of mental health disorders.

 

Cognitive Decline and Brain Health

Lack of sleep impairs:

  • memory

  • attention

  • decision-making

Over time, chronic sleep deprivation may increase risk of neurodegenerative disorders.

 

Sleep Debt and Inflammation

Chronic sleep loss elevates inflammatory markers.

Persistent inflammation contributes to:

  • metabolic syndrome

  • cardiovascular disease

  • autoimmune conditions

Preventing sleep debt reduces systemic inflammation.

 

Can Sleep Debt Be Recovered?

Short-term sleep debt can be partially recovered through:

  • consistent longer sleep

  • improved sleep hygiene

However, chronic sleep deprivation requires long-term behavioural changes.

Weekend “catch-up sleep” offers temporary relief but does not fully reverse long-standing sleep debt.

 

Warning Signs of Sleep Debt

Common indicators include:

  • reliance on caffeine

  • difficulty waking up

  • daytime drowsiness

  • poor focus

  • frequent illness

Persistent symptoms require lifestyle correction.

 

Practical Strategies to Reduce Sleep Debt

Maintain a Consistent Sleep Schedule

Go to bed and wake up at the same time daily.

 

Limit Screen Exposure Before Bed

Blue light suppresses melatonin production.

 

Create a Sleep-Friendly Environment

Dark, quiet and cool environments improve sleep quality.

 

Manage Stress

Relaxation techniques reduce cortisol levels and support sleep.

 

Avoid Heavy Meals and Caffeine at Night

These disrupt sleep cycles.

 

Role of Preventive Health Checkups

Screening helps detect:

  • hypertension

  • metabolic imbalance

  • stress-related conditions

Sleep quality assessment should be part of preventive care.

 

Long-Term Benefits of Adequate Sleep

Restorative sleep supports:

  • stable mood

  • strong immunity

  • healthy weight

  • improved productivity

  • reduced disease risk

Sleep is foundational to wellness.

 

Conclusion

Understanding sleep debt and its impact on the body highlights the critical role sleep plays in maintaining physical and mental health. Chronic sleep loss disrupts hormones, weakens immunity, increases metabolic risk and affects heart health. While occasional sleep loss may be manageable, consistent deprivation carries serious long-term consequences. Prioritising adequate, high-quality sleep is one of the most powerful steps toward protecting overall health and preventing chronic disease.
