World Aids Day
The global challenge of HIV/AIDS remains one of the most pressing public health issues today. According to the latest data from UNAIDS, around 38.4 million people worldwide are living with HIV/AIDS, underlining the need for not only medical intervention but also comprehensive awareness, education, and social change. Despite the significant strides made in treatment and prevention, the confusion surrounding the relationship between HIV and AIDS still persists.
Young people have become influential advocates in the fight against HIV/AIDS. Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities. These young activists utilize digital platforms and peer-to-peer education to dispel myths, promote safe practices, and foster supportive environments for those affected by HIV/AIDS.
Dr Gowri Kulkarni, an expert in Internal Medicine, explains that while the terms HIV and AIDS are often used interchangeably, they are distinctly different. "HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, whereas AIDS (Acquired Immunodeficiency Syndrome) is a condition that occurs when HIV severely damages the immune system," she clarifies. To understand the implications of these differences, it's important to explore the fundamental distinctions between the two.
HIV is the virus responsible for attacking the body’s immune system, specifically targeting CD4 cells, which are crucial for the body’s defense against infections. As HIV progresses, it destroys these cells, weakening the immune system over time. If left untreated, this continuous damage can lead to AIDS.
AIDS, on the other hand, is a syndrome, not a virus. Dr Kulkarni further elaborates that AIDS is a collection of symptoms and illnesses that emerge when the immune system is severely compromised due to prolonged HIV infection. It represents the most advanced stage of HIV, and is characterized by very low CD4 counts or the onset of opportunistic infections like tuberculosis, pneumonia, or certain cancers.
A key distinction to remember is that not everyone with HIV will progress to AIDS. Thanks to advancements in medicine, particularly antiretroviral therapy (ART), individuals living with HIV can manage the virus and maintain a healthy immune system for many years, or even decades, without ever developing AIDS. ART works by suppressing the virus to undetectable levels, effectively preventing the damage HIV would otherwise cause to the immune system.
Without treatment, however, HIV progresses through three stages:
- Acute HIV Infection: This stage occurs shortly after transmission and may include symptoms like fever, fatigue, and swollen lymph nodes.
- Chronic HIV Infection: Often asymptomatic or mildly symptomatic, the virus continues to damage the immune system but at a slower rate.
- AIDS: This is the final stage, marked by severe immune damage and the presence of infections that take advantage of the compromised immune defenses.
Another key distinction between HIV and AIDS is the way in which they are transmitted. HIV is highly contagious and can be transmitted through the exchange of bodily fluids such as blood, semen, vaginal fluids, and breast milk. It is primarily spread through unprotected sexual contact, sharing needles, or from mother to child during childbirth or breastfeeding.
AIDS, however, is not transmissible. It is not a disease that can be passed from one person to another. Rather, AIDS is the result of untreated, advanced HIV infection and is a direct consequence of the virus’s damage to the immune system.
HIV and AIDS are diagnosed through different methods. HIV is diagnosed through blood tests or oral swabs that detect the presence of the virus or antibodies produced by the immune system in response to the virus. Early detection of HIV is crucial, as it allows for timely intervention and treatment, which can prevent the virus from progressing to AIDS.
AIDS, on the other hand, is diagnosed using more specific criteria. Dr Kulkarni notes that the diagnosis of AIDS is made when the individual’s CD4 cell count falls below 200 cells/mm³, or when opportunistic infections or certain cancers (such as Kaposi's sarcoma or lymphoma) are detected. Diagnosing AIDS involves a more thorough assessment of the individual’s immune function and overall health, as opposed to just the detection of HIV.
The treatment goals for HIV and AIDS differ significantly, although both involve antiretroviral therapy (ART). For HIV, the primary treatment goal is to suppress the virus to undetectable levels, thus maintaining a strong immune system and preventing further transmission of the virus. People living with HIV can often live long, healthy lives if they adhere to ART.
For individuals diagnosed with AIDS, the treatment plan becomes more complex. While ART remains an essential part of managing the virus, treatment for AIDS also focuses on addressing the opportunistic infections and secondary health complications associated with severe immune suppression. The goal of treatment for AIDS is not only to manage the HIV virus but also to improve the quality of life and extend survival by treating these secondary health issues.
While the medical community has made great strides in managing HIV, the battle to curb its transmission is also a social and cultural issue. Dr Daman Ahuja, a public health expert, highlights that HIV/AIDS awareness and education are vital to reducing transmission rates and supporting those affected by the virus. "Young people, especially, have become key advocates in the fight against HIV/AIDS," says Dr Ahuja. "Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities."
Additionally, grassroots activism plays a significant role in raising awareness and addressing stigma. As the World Health Organization reports, community-based interventions have been proven to increase HIV testing rates and improve treatment adherence, which are crucial in the fight against the pandemic.
The ultimate goal of organizations like UNAIDS is to eliminate the HIV/AIDS pandemic by 2030. Achieving this requires global collaboration, from medical treatment advancements to public health strategies, education, and advocacy. Dr Kulkarni’s insight underscores the importance of early detection, treatment adherence, and community support in the fight against HIV/AIDS.

Magnesium and melatonin are both popular supplements, especially among people looking to get more shuteye, but can combining them improve your sleep? Some research indicates that taking magnesium and melatonin together could improve sleep quality, though stronger, larger studies are needed to confirm the effect.
Studies on using magnesium and melatonin together are limited, but some evidence suggests it could benefit sleep in certain individuals.
As per Health, one study focusing on women with polycystic ovary syndrome found that taking both magnesium and melatonin improved sleep quality. Another study reported that people with sleep difficulties who used a combined magnesium-melatonin supplement for four weeks noticed modest improvements in how well they slept.
The exact reason why the two work together is not completely understood, but magnesium and melatonin may influence each other in a way that supports sleep.
“Magnesium does have an effect on melatonin levels,” said Marie van der Merwe, PhD, coordinator of the applied physiology and nutrition doctoral program at the University of Memphis, speaking to Health. “The amount of magnesium you have can influence how well your body produces melatonin.”
You don’t necessarily need to take the two supplements at the same time to benefit, van der Merwe noted. It’s fine to take magnesium in the morning and melatonin before bed.
The takeaway: There could be a link between magnesium and better sleep, but more research is needed to be sure.
Magnesium is a vital mineral that supports nerve and muscle function, regulates blood pressure and blood sugar, and contributes to the formation of bone, protein, and DNA. As per Mayo Clinic, it is also commonly taken to help with sleep, but it is not without risks.
Some studies suggest magnesium may help sleep by:
Improving sleep quality: Ensuring adequate magnesium through diet or supplements may help people with deficiencies sleep better and ease anxiety.
Reducing muscle tension: Magnesium can help relax muscles and relieve tension, which can make it easier to fall asleep.
Research on magnesium for sleep is limited. Supplements aren’t regulated by the FDA for safety or effectiveness and carry potential risks:
Delayed effect: It may take several weeks before magnesium supplements noticeably improve sleep.5
Side effects: High doses can cause diarrhea, nausea, and stomach cramps.7
Drug interactions: Magnesium can interfere with some medications, reducing their effect or increasing side effects. Talk to a doctor before starting any new supplement.7
Melatonin is a well-known sleep aid, though it’s actually a hormone your body naturally produces to regulate sleep-wake cycles.⁸ “Melatonin is in charge of running the [internal] clock, and it really is important for regulating your circadian rhythms,” van der Merwe said.
Works quickly when needed: Unlike magnesium, melatonin can act soon after taking it, making it useful for occasional sleepless nights.
May help you fall asleep faster: Studies show that a 2-milligram dose of melatonin helped some people fall asleep about nine minutes sooner than placebo.
Supports sleep timing: Melatonin can help shift workers, travelers with jet lag, or those with irregular sleep schedules align their sleep patterns.
Melatonin can help with some sleep difficulties but won’t fix all sleep disorders, van der Merwe said. Like magnesium, melatonin isn’t FDA-regulated:
Long-term effects unclear: There’s limited data on the safety of long-term melatonin use.
Medication interactions: Melatonin may interact with antibiotics, antidepressants, and birth control.
Caution for certain groups: It’s generally not recommended for children or people with dementia, and should be used carefully by those with seizures or on blood thinners.
It’s wise to speak with a healthcare professional before starting any new supplements, alone or in combination.
Van der Merwe emphasized that sleep problems can stem from issues that supplements alone won’t fix. Conditions like cardiovascular disease, type 2 diabetes, and depression can affect sleep.
If you want to try one or both supplements, a doctor can help determine the best timing for magnesium, melatonin, or a combined product.
“Melatonin [should] increase at night,” van der Merwe explained, so it is crucial to take it at the right time. Taking it in the morning can disrupt your internal clock.
Even though sleep-support supplements like magnesium and melatonin have grown in popularity, it’s important to consult a professional to see if they will help in your situation.

Chronic obstructive pulmonary disease (COPD) has long been seen as a condition of older adults, typically tied to years of smoking. But across India, pulmonologists are increasingly diagnosing it in people in their 20s and 30s. This shift, experts say, reflects a deeper and more troubling change: young adults are growing up and living in environments where the lungs never truly get a chance to breathe clean air.
The biggest change is the cause itself. As Dr. Raja Dhar, Director & HOD, Pulmonology, CK Birla Hospitals, CMRI Kolkata, explains, “COPD is increasingly becoming an ‘exposure disease’ rather than a ‘smoker’s disease.’ In India, non-smoking COPD is numerically a much larger problem.”
This exposure begins early—sometimes in childhood.
Dr. Dhar highlights how even limited exposure can have lifelong consequences: “Severe airway obstruction can be traced back to just six to seven years of biomass smoke exposure in a poorly ventilated kitchen during a child’s formative years.”
Dr. Harshil Alwani, Consultant – Pulmonology, CK Birla Hospitals, Jaipur, also points to the changing risk profile. According to him, “newer epidemiological data show that non-smoking drivers—especially air pollution and occupational exposures—are playing a disproportionately large role in younger people.” He adds that rapid urbanisation means more young adults are chronically breathing polluted air from childhood onwards.
Improved diagnosis and greater awareness also mean younger patients with persistent symptoms are now being evaluated more often, he notes.
Both experts agree that polluted air is the biggest trigger today. Dr. Alwani explains that long-term exposure to PM₂.₅ is directly linked to lung decline and COPD. “Recent research shows that temperature and humidity modulate the harmful effect of PM₂.₅, making COPD risk worse under certain climatic conditions,” he says.
Dr. Dhar adds that India’s air quality is deteriorating nationwide: “Ambient outdoor air pollution is a severe risk, as air quality across 98% of India is worse than WHO standards.”
Household pollution remains a massive issue. Biomass fuel used for cooking is, as Dr. Dhar puts it, “the largest non-smoking contributor, resulting in numbers approximately three times that of smoking-related COPD.”
Young adults working in construction, mining, welding, or factory settings face daily exposure to dust, fumes, and chemicals. Dr. Alwani notes that such environments “carry a significantly increased risk.”
Recurrent infections can impair lung development and reduce lung reserve, making early-onset disease more likely.
Conditions like alpha-1 antitrypsin deficiency, though rare, still contribute when combined with environmental triggers.
Every winter, Delhi’s smog becomes a health emergency. According to Dr. Dhar, “High winter pollution, particularly hazardous levels of PM2.5, acts as a chronic, low-grade chemical burn on the young respiratory system.”
Dr. Alwani adds that winter inversion traps pollutants closer to the ground, amplifying PM₂.₅’s damage.
Vaping and e-cigarettes, widely perceived as harmless, have added a new layer of risk. Dr. Alwani warns, “Vaping is not benign. Its aerosols contain volatile compounds, heavy metals, and ultrafine particles that trigger inflammation and oxidative stress—central pathways to COPD.”
Dr. Dhar echoes this concern: “Any inhalation of heated chemical aerosols is a significant lung irritant and pro-inflammatory agent.”
Doctors urge young adults not to dismiss symptoms like:
Early spirometry can dramatically change outcomes. As Dr. Dhar puts it, “Early intervention allows us to remove the source of exposure and start therapy, which can effectively preserve the patient’s remaining lung function.”
Dr. Alwani adds that catching the disease early can “significantly slow further lung damage” and prevent long-term complications.

We all know the feeling of FOMO, the fear of missing out, but there exist another fear, this is FOFO: the fear of finding out. This apprehension is what keeps people from boking their health screenings. The horrors of what will happen after a mammogram, a Pap smear, an STD test, blood panel, or even something as simple as a blood pressure check can scare those with FOFO.
While the term itself is not a medical diagnosis, it is a widely recognized behavioral pattern that both patients and doctors get to see frequently. Over the years, it has gained more attention among experts who deal with health anxiety. As one clinical psychologist explains, there isn’t much published research on FOFO, but practitioners who work with health-related anxiety are very familiar with its impact.
What is even worrying is how common this avoidance has become. As per a 2025 survey of 2,000 employed US adults, 3 out 5 avoid medical screenings altogether, due to fear of bad news or embarrassment. Another 2025 reveal that of 7,000 adults, only 51% attended a routine medical appointment of cancer screening, with a 10% drop from 2024.
The attitude is: "If I don't know it, I can't have it".
According to psychologists, FOFO often roots itself in anxiety and the desire for control. When something feels uncertain—like a health test result—many people instinctively avoid it. Avoidance becomes a way to quiet the anxiety, at least temporarily.
Experts say FOFO is especially common in people with generalized anxiety disorder, OCD, or illness anxiety disorder. But anyone can experience it. For some, it’s a one-off situation—like hesitating over a prostate exam. For others, it’s part of a broader coping style that involves avoiding anything that feels threatening. Ironically, this sometimes goes hand in hand with endlessly checking symptoms online.
Previous negative experiences in healthcare settings can also feed FOFO. Some people feel anxious around doctors or medical procedures, while others fear being judged, especially when a screening could uncover conditions that carry social stigma—such as STDs. There’s also the fear of receiving results that might force lifestyle changes or treatments they’re not ready for.
A common unspoken belief behind FOFO is:
“If I don’t take the test, then the problem doesn’t exist.”
Waiting for test results adds to the anxiety too. When results take days or weeks, the uncertainty can feel more stressful than the test itself.
The first step is by acknowledging what is at stake. Many experts recommend weighing the pros and cons of taking the test versus avoiding it. If FOFO is holding you back, ask yourself what exactly you’re afraid of. Many people underestimate their ability to handle bad news. Understanding this can help reduce the emotional weight of screening.
These questions often shift the focus from fear to long-term wellbeing. As psychologists note, facing the fear usually leads to decisions that better align with your values.
