On November 7, Delhi Air Quality Index (AQI) logged its average pollution levels at 727. Previously, in 2024, on November 18, Delhi logged AQI at 795 (as per the AQI.in data, and reported by several other media outlets). Amid all this, on November 9, Delhiites, including parents, students, activists, and many more assembled at India Gate to hold a protest against the worsening AQI.
As Delhi pollution keeps worsening, it is no longer news that air pollution impacts much beyond just lungs and respiratory system of one's body. It could lead to hormonal imbalance, fertility, skin and hair problems, and even impact bone health.
The situation is of such a gravity that even doctors are now suggesting people to leave Delhi for a while, if they could afford to do so. Doctors are also suggesting people the Do's and Dont's of staying safe in this continuous worsening pollution. One such doctor is Dr Rahul Chawla, a neurologist trained at AIIMS, who, on his Instagram, posted a video where he shared 5 ways one could protect themselves from Delhi's Air Pollution.
Dr Chawla also criticized the government for not taking immediate actions. He said, "While Beijing’s AQI dropped from 754 (2013) to just 47 (2025) after strict climate action, Delhi’s air is getting worse every winter. Schools are shutting, visibility is zero, and people are literally breathing poison. Delhi is converting into a gas chamber. If lockdowns were for COVID, maybe the next one will be for air pollution.”
As city becomes 'gas chambers' one needs to be a step ahead to ensure their own safety. Here's what they can do:
Dr Chawla suggested that one should stay indoors as much as possible. "You can open the windows and doors only between 1 and 3pm in the day, when you feel that the sun is bright, so that the house gets proper ventilation," he said.
Why 1pm to 3pm is the only time he suggests to have exposure with air? As per a 2023 study by an air filter brand, Delhi's air pollution peaked at 9AM and gradually improved as the day progressed. On an average, Delhi sees roughly as half as much PM2.5 by 5PM. Similarly, in Kolkata, the pollution peaks at 8am and is lowered by 4PM. This is why the safest time to have any sort of air exposure is in the afternoon. Pollution levels also tend to be slightly lower in the afternoon because it is when the sun is at its peak. This heats the ground and causes warm air to rise and mix with atmosphere. This helps disperse pollutants.
He also advised against cleaning inside the house using a dry cloth, and suggested wet cloth to be in use, so that dust does not rise. "Please do not light up things inside the house like burning dhoop (incense for worship), agarbatti (incense sticks), or anything else that causes excessive smoke,” he said.
“If there are elderly people at home, do not let them go for morning walks or evening walks, and if there are children, do not let them play in the park. Exercise at home. You can go up and down the stairs. You can do yoga. If you have a treadmill or a stationary bike at home, you can exercise with it. You can do weightlifting,” he said. However, he suggested that if going out is absolutely necessary, then one must wear N-95 mask properly before stepping out.
“If you can afford an air purifier, buy one. But keep in mind that the air purifier you are buying should be appropriate for the size of your room,” the neurologist advised.
The neurologist also suggested that if your company permits it, seek work from home option to reduce your exposure from toxic air.
Lastly, he suggested that if people can afford, and their profession allows, they must leave Delhi for a few weeks. “Because this city has become a gas chamber,” he warned.

Vitamin C is a star ingredient in the skincare world for some very good reasons. It can be hailed as a magic wand to evaporate your stubborn marks and give you a brighter complexion.
However, no matter what product you use, the results do not appear overnight. So, what do real results look like? What does a before-and-after journey of using a Vitamin C serum actually entail?
This guide covers everything about the before-and-after results of using the Vitamin C serum.
It is a potent antioxidant that can be applied to your skin directly. It neutralises the effects of free radicals, which are tiny and unstable molecules caused by pollution and UV rays. They can easily damage your skin and accelerate ageing.
Vitamin C helps by boosting collagen production and improving skin tone. This is why the results of Vitamin C on the face are so dramatic. It changes the flat look of your skin to a healthy glow.
Key benefits include:
· Brightening: It blocks the enzyme responsible for producing pigment, leading to more radiant skin.
· Fading Marks: A remarkable ingredient for targeting sun damage and acne scars.
· Collagen Stimulation: It keeps your skin bouncy and firm.
· Protection: It provides a second layer of defence against environmental stress.
Consistent use of the serum for several weeks, along with daily application of sunscreen with SPF 50 can yield noticeable results. Here’s what you can expect from it.
Before Using Vitamin C Serum
Your skin may show signs of environmental wear and tear before you start using a serum. The following are some common complaints:
· Your skin looks tired, even after a full night's sleep.
· You may have patchy skin or dark areas around the mouth and forehead.
· Old acne spots or sun freckles that refuse to fade.
· Skin that feels slightly rough or looks congested.
After Consistent Use
The changes in your face before and after using a vitamin C serum become evident after your skin integrates the serum into its renewal cycle:
· It will give you that lit-from-within look.
· Dark spots become significantly lighter and blend into your natural skin tone.
· Your skin feels more elastic and youthful due to increased collagen.
· The surface of your skin looks smoother.
First Week: Initial Freshness & Surface Glow
There is little change in dark spots during the first few days. However, you may notice an immediate glow on your skin surface. The serum hydrates and smoothens the skin's surface, helping makeup sit better. Vitamin C for dark spots before and after signs are clearly visible.
2–4 Weeks: Brightening & Early Spot Lightening
You will start to see the before-and-after progress of vitamin C on dark spots around this stage. Its pigment-blocking properties start to kick in. You may notice that your overall skin tone looks fresher and that the edges of your dark spots are now fading.
4–8 Weeks: Visible Even Tone and Improved Texture
The difference between your face before after vitamin C serum will be more obvious by the end of the second month. The deeper layers of the skin benefit from the antioxidant protection. You can expect the following changes:
· Visibly less sun damage
· Even complexion, so you may not need concealer
· Fewer rough patches
8–12 Weeks: Long-Term Transformation
After 90 days, your skin has gone through multiple renewal cycles. Your Vitamin C serum before-and-after photos may show significant improvement in hyperpigmentation. Fine lines may reduce because of the increased collagen, as your skin looks the healthiest it has in years.
If you want your before-and-after vitamin C serum results to be impressive, you need to follow these simple rules:
1. Morning is Best: Apply your serum in the AM. This allows the antioxidants to protect your skin from pollution and sunlight throughout the day.
2. Pair with Sunscreen: Always follow up with a sunscreen. Vitamin C is not a replacement for sunblock, but it actually makes your sunscreen with SPF 50 more effective by neutralizing the rays that slip through.
3. Storing the Serum: Vitamin C is sensitive to light and air. Keep your bottle in a cool, dark place (such as a drawer) to ensure it does not lose its potency. If your serum has become dark or orange in colour, it may have been oxidised. So, it may not work well.
4. Consistency: You do not need a huge amount of serum. 3–4 drops are enough. You need to apply it every single day without skipping.
The journey of your face before and after Vitamin C serum can feel long, but the results are worth it. It can be exciting to see the initial glow. However, the real changes, such as fading deep dark spots and firming the skin, take time. Stick to a routine and pair your skin with a high-quality sunscreen to stay radiant and youthful.

Scientists say they have uncovered the first strong evidence that a specific type of brain training could meaningfully reduce the risk of Alzheimer’s disease. The findings come from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study, a large US clinical trial that followed 2,802 healthy adults aged 65 and older for 20 years. Published in Alzheimer’s & Dementia: Translational Research & Clinical Interventions, the research found that participants who completed a targeted “speed of processing” brain training programme, along with booster sessions, had a 25 per cent lower risk of developing dementia compared to those who received no training.
Dementia remains one of the most pressing health challenges worldwide. In the UK alone, around 900,000 people live with the condition, with Alzheimer’s disease being the most common form. There is currently no cure. While newer drugs may modestly slow cognitive decline for some patients, they do not stop or reverse the disease.
That is why prevention, or even delay, is so crucial. Even pushing back the onset of dementia by a year or two across the population could significantly reduce strain on families, healthcare systems and social care services.
Lifestyle factors already play an important role. Regular exercise, managing blood pressure and diabetes, avoiding smoking and staying socially active are all linked to lower dementia risk. Now, this new research suggests that certain types of structured mental training may also help.
Back in the late 1990s, researchers randomly assigned older adults to one of four groups:
Each participant attended ten hour-long sessions over five to six weeks. Some who completed most of the sessions were later randomly selected to receive additional “booster” sessions about 11 months later and again after 35 months. In total, participants completed between 10 and 22½ hours of training spread over three years.
Memory training focused on mnemonic techniques. Reasoning training involved identifying patterns and solving structured problems. But it was the speed-of-processing training, delivered through a computer-based programme, that stood out.
One of the key exercises, called Double Decision, required participants to quickly identify a central object (like a specific car) while simultaneously locating a road sign that briefly flashed in their peripheral vision. As players improved, the images appeared for shorter periods, increasing difficulty.
The best possible score in the game was 32 milliseconds. The average score hovered around 100 milliseconds, but participants who stuck with the programme often improved to about 50 milliseconds — nearly doubling their processing speed.
Unlike memory drills, this training targeted how quickly and accurately the brain processes visual information — a skill that tends to decline with age.
Researchers tracked participants’ health records to see who was later diagnosed with Alzheimer’s disease or related dementias. Nearly half of the control group developed dementia during the two-decade follow-up.
The same held true for those who received memory or reasoning training.
However, the group that completed speed training and received booster sessions had a strikingly different outcome: their risk of dementia diagnosis was 25 per cent lower than the control group.
The researchers themselves urge caution. The people who benefited most were those who completed the initial sessions and returned for boosters. It’s possible that these individuals were already more motivated, healthier, or cognitively stronger — factors that may independently reduce dementia risk.
To address this, booster sessions were randomly allocated among eligible participants, and analyses adjusted for age, education, baseline cognitive performance and other health factors. Still, no statistical method can completely eliminate the possibility that the most engaged participants were also those most likely to stay healthier longer.
Henry Mahncke, chief executive of Posit Science — the company behind the training software — described the results as “astonishing” and potentially transformative for brain health.
The academic authors, including researchers from Johns Hopkins School of Medicine, the University of Pennsylvania and the University of Washington, were more measured. They concluded that speed-of-processing training “has the potential to delay the diagnosis” of Alzheimer’s and related dementias — but further research is needed.
If confirmed, the implications could be profound. The idea that even later-life brain training might buy people more time before dementia sets in offers a rare note of hope in a field where breakthroughs are hard won.

Can Chinese medicine cure baldness? Baldness has long been dealt as a matter of shame over health. Products focus on hiding the bald patch rather than curing it. Baldness has in the past made global headlines when South Korean president Lee Jae Myung said 'Baldness is the new enemy' and suggested that insurance should cover the treatment as a part of medical treatment.
Androgenetic alopecia (AGA), better known as pattern hair loss, is the most common form of hair thinning worldwide. While medications like finasteride and minoxidil remain the standard line of treatment, concerns around side effects, lifelong use, and mixed results have led many people to explore gentler, more holistic alternatives.
A new scientific review now suggests that Polygonum multiflorum—a root used in traditional Chinese medicine for over a thousand years—may hold real promise in managing AGA. Historically described as a remedy that can “blacken hair and nourish essence,” the herb is gaining renewed attention as modern research begins to unpack how it actually works at a biological level.
Most conventional hair-loss treatments target a single biological mechanism. Polygonum multiflorum, however, appears to work on several fronts at once. According to the review, the herb helps reduce the activity of dihydrotestosterone (DHT), a hormone strongly associated with hair follicle shrinkage in AGA.
At the same time, it protects hair follicle cells from premature cell death and activates key growth-related signalling pathways, including Wnt and Sonic Hedgehog (Shh), both crucial for maintaining a healthy hair growth cycle. The herb may also improve scalp blood circulation, potentially enhancing the delivery of oxygen and nutrients to hair follicles—an often overlooked factor in hair thinning.
“Our analysis bridges ancient wisdom and modern science,” said Han Bixian, the lead author of the review published in the Journal of Holistic Integrative Pharmacy. “What surprised us was how consistently historical texts—from the Tang Dynasty onward—described effects that align closely with today’s understanding of hair biology.”
The researchers examined a wide range of evidence, including laboratory studies, clinical observations, and historical herbal literature. Together, these sources suggest that Polygonum multiflorum does more than simply slow hair loss—it may actively support healthier hair function.
One of the most striking findings is the herb’s potential role in hair regeneration. Rather than only delaying further thinning, Polygonum multiflorum appears to influence multiple growth factors involved in restarting and sustaining the hair cycle. This broader mode of action could give it an edge over treatments that focus on just one biological target.
The review notes that when properly processed—a critical step in traditional preparation, the herb shows a relatively favorable safety profile. This could make it more appealing to patients concerned about side effects such as sexual dysfunction or scalp irritation commonly linked to existing medications.
That said, the authors stress the need for more high-quality clinical trials to confirm effectiveness, establish safe dosing, and standardize preparation methods. Even so, the findings highlight how rigorous scientific study of traditional remedies can uncover new possibilities for treating common conditions like androgenetic alopecia.
