Your skin tell a lot about your health. By just looking at someone's skin, one can tell if they are sick, unhappy, or completely healthy. This is because whatever happens inside, reflects on the outside, on your skin. But there are ways to take care of your skin otherwise and it always does not mean expensive products or complicated routine. A basic skincare regimen includes cleansing, moisturizing, and sunscreen. Beyond this, good food with enough nutrition, regular exercise, sufficient sleep and stress management too is the key.

Here's all you need to know about skincare:

Who all need skincare?

Despite what social media tells you, children do not need fancy skincare products. The best approach for them is, once they start approaching the pre-puberty time, they keep their skin clean and use a non-comedogenic moisturizer if necessary. For children with eczema or other skin conditions, following a doctor-recommended routine is important.

Fighting Acne

Everyone experience acne at some point, especially during puberty. The best hack is to use oil-free products like benzoyl peroxide that can help control breakouts. If acne are causing scars, it is best to first take advise from your doctor and only then apply something else. A treatment usually takes up three-months to finally show results, therefore before considering alternatives a three-month window must be given.

When Should you start using anti aging products?

Again, social media here tells you to use it as soon as possible. But did you know that using anti aging products early will not help prevent wrinkles? A simple routine with a good sunscreen is often the best approach. Those in their mid-to-late 20s may consider introducing a mild retinol product, but factors like sun exposure and individual skin needs play a role in determining the right time to start.

What Ingredients Work?

Certain ingredients have proven beneficial, these are:

• Retinol for skin renewal
• Sunscreen for preventing premature aging

There may be many trendy ingredients like hyaluronic acid, however, not necessarily does it penetrate the skin deeply, but instead it helps retain moisture on the surface. Expensive doesn’t always mean better—affordable products often work just as well.

Do's and Dont's

Be Cautious: It is important that you be cautious when you use new products. Before introducing a new product, always take a patch test, especially for sensitive skin. For instance, retinol should be used only in small amounts a few times a week to prevent dryness. However, if it creates irritation, you can reduce usage, or switch to a milder formation.

Popping Pimples: This could lead to scarring and worsen inflammation, this is when spot treatments with salicylic acid or benzoyl peroxide could help. Also consider using face wash.

Use Sunscreen: Remember, sunscreen is a skincare essential! It also reduces the risk of skin cancer and prevent sun-induced aging. It is always best to apply a sunscreen with an SPF 50+. Remember to always go for a cream over spray and reapply every two hours.

Moles: Keep an eye on your moles. Though, mostly they are harmless, but if the size, shape, or color changes, then you must go see a doctors. While most moles are harmless, some could turn into cancer.

Lifestyle Changes: What really does well for your skin is when you start eating a healthy diet, rich in whole foods, healthy fats and variety of plants. Moreover if you are smoking, it accelerates aging and reduces blood flow to skin. Thus make these changes to make your skin radiant.

It has been long suspected that Western diets could contribute to the risk of colorectal cancer. The theory may finally have a clearer scientific explanation.

A new study suggests that gut bacteria can convert compounds produced by high-fat, low-fibre diets into cancer-causing chemicals. The research sheds light on how unhealthy eating habits may lead to cancerous tumour growth in colon in the long term.

What Did The Study Find?

Published in the journal Gut, the research was led by Dr. Annika Osswald (first author) and Dr. Soeren Ocvirk (corresponding author), along with a large team of international scientists.

The collaboration included researchers from Technical University of Munich (TUM), Germany, German Institute of Human Nutrition (DIfE), RWTH Aachen University, Freie Universität Berlin, University Hospital of Regensburg, and other institutions.

Researchers found that a western-style diet, which is commonly high in red and processed meat, saturated fats, refined carbohydrates and ultra-processed foods, significantly changes the composition of the gut microbiome.

These altered bacteria then modify bile acids in ways that promote inflammation and create an environment that accommodates the development of colorectal cancer tumours.

According to the researchers, diet alone is not the only factor. The trillions of microbes living in the intestine determine how food is processed, producing metabolites that can either protect the gut or damage it.

The study found that specific bacterial groups transformed bile acids into compounds that stimulated tumour growth in the colon.

This provides one of the strongestt explanations yet for why western dietary patterns have consistently been associated with higher risk of colorectal cancer.

"Our findings highlight the critical interaction between diet, gut microbes and cancer biology," the researchers noted, adding that targeting the microbiome could become a future strategy for preventing colorectal cancer.

Negative Effects Of Western Diet

A western diet typically includes:

• High amounts of processed and red meat
• Fried foods and saturated fats
• Sugary drinks and desserts
• Refined grains
• Low intake of fruits, vegetables, legumes and whole grains

Previous research has repeatedly linked this eating pattern with obesity, diabetes, heart disease and colorectal cancer, but scientists have long found it challenging to explain the exact cause until now.

Importance Of Gut Microbiome

The human gut is home to trillions of bacteria that help digest food, regulate immunity and produce beneficial compounds like fatty acids.

A fibre-rich diet supports good bacteria that reduce inflammation, whereas diets high in fat and processed foods can cause microbial imbalance.

The new findings suggest this imbalance changes how bile acids are metabolised, increasing the production of molecules capable of damaging the colon and supporting cancer growth in the long run.

Colorectal Cancer Is Rising Among Younger Adults

Earlier research has linked harmful gut bacteria, including toxin-producing E. coli, with DNA damage that may begin early in life and contribute to the rise of colorectal cancer among younger people.

However, the latest findings do not prove diet alone causes cancer. Genetics, obesity, physical inactivity, sedentary life, smoking and alcohol consumption also influence risk.

However, they say maintaining a fibre-rich diet with fruits, vegetables, legumes and whole grains may help preserve a healthier gut microbiome and lower long-term colorectal cancer risk.

Could air pollution may do more than harm the lungs and heart? A new study has found that exposure to polluted air could trigger painful flare-ups in people living with rheumatoid arthritis (RA).

The study comes when evidence is mounting that environmental factors contribute significantly to autoimmune diseases.

About The Research

The study, published in the Annals of the Rheumatic Diseases, found that excessive exposure to air pollutants, particularly fine particulate matter (PM2.5), was associated with increased rheumatoid arthritis activity and a greater risk of flare ups.

Researchers say the findings suggest that improving air quality should become an important part of managing the chronic condition, alongside treatment, medications and lifestyle changes.

"Our findings highlight that environmental exposure, especially air pollution, may significantly influence rheumatoid arthritis disease activity and flare risk," the researchers said, noting that patients and clinicians should consider air quality as a modifiable risk factor.

About Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease in which the immune system attacks healthy joints, causing pain, swelling, stiffness and, over time, permanent joint damage.

While genetics, smoking and infections have been recognised as risk factors, scientists are investigating how environmental pollutants may worsen the disease.

The latest findings are particularly relevant for countries such as India, where millions are exposed to unhealthy air for large parts of the year. Previous reports have already linked poor air quality in cities like Delhi to rising concerns over autoimmune diseases.

A flare is a period when rheumatoid arthritis symptoms suddenly worsen. During this time, people may experience:

• Severe joint pain and swelling
• Morning stiffness lasting longer than usual
• Fatigue and weakness
• Difficulty performing everyday tasks

Flares can last from a few days to several weeks and are often triggered by infections, stress, missed medications or other environmental factors.

Researchers believe tiny airborne particles like PM2.5 can enter the lungs and bloodstream, triggering inflammation throughout the body.

This inflammatory response may overstimulate the immune system, making rheumatoid arthritis symptoms worse and increasing the likelihood of painful flare-ups.

Is There More Evidence?

The researchers emphasised that the study shows an association rather than proving that air pollution directly causes rheumatoid arthritis flares.

However, the consistent link suggests reducing exposure to polluted air may help lower the chances of flare-ups in high-risk individuals.

Experts advise patients to continue prescribed medications, constantly monitor local air quality, avoid outdoor activities during periods of severe pollution when possible, and discuss symptom changes with their rheumatologist.

The findings add to a growing body of research linking air pollution with autoimmune diseases.

Earlier studies have suggested that long-term exposure to pollutants may increase the risk of developing rheumatoid arthritis, while the new research indicates polluted air may also worsen symptoms in people already living with the disease.

Commonly prescribed medicines for high blood pressure and heart disease could also help antidepressants work better, according to a new study by researchers at the All India Institute of Medical Sciences (AIIMS).

The research offers hope for people with depression whose condition is not adequately managed with standard antidepressants.

About The Study

The study found that certain cardiovascular medications, when taken along with antidepressants, may improve the brain's response to treatment, potentially making clinical depression treatments more effective.

The findings establish a foundation for repurposing common medicines to improve mental health treatment. The researchers stress that larger clinical trials are needed to validate the study before it can be included in standard depression treatments.

"Our findings suggest that some drugs already being used to treat hypertension and heart disease may have the potential to act as adjuncts to antidepressant therapy," the AIIMS research team said.

They also said that the strategy could particularly benefit patients who do not respond to antidepressants well.

How Can The Findings Help?

Even though depression affects hundreds of millions of people worldwide, almost one-third of patients do not receive adequate relief from their first antidepressant.

Even when medications work, they often take several weeks to show results. This has led researchers to explore more ways to improve treatment outcomes, especially for mental health issues.

Repurposing existing medicines is considered an attractive strategy because their safety profiles are already well understood, potentially reducing the time and cost needed to bring new treatment options into clinical practice.

How Could Heart Medicines Improve The Efficacy Of Antidepressants?

Antidepressants, including selective serotonin reuptake inhibitors (SSRIs), are among the most commonly prescribed medicines for moderate to severe depression. They work by changing the levels of neurotransmitters like serotonin in the brain, helping regulate mood over time.

However, individual responses may vary widely, and many patients end up needing multiple treatment approaches before achieving any relief.

While the exact biological mechanisms are still under investigation, researchers believe that some cardiovascular drugs may have an effect on pathways associated with inflammation, blood flow to the brain, or nerve signaling, all of which are increasingly play a role in depression treatment.

The researchers noted that these medicines are not intended to replace antidepressants. Instead, they could eventually be used alongside standard treatment to improve its effectiveness in some patients.

Word Of Caution

Experts caution that patients should not start or stop blood pressure or heart medications in the hope of treating depression without clinical supervision.

More clinical studies are required to identify which cardiovascular drugs offer the greatest benefit, which patients are most likely to respond, and whether the combination remains safe over long-term use.

The AIIMS study could pave the way for a cost-effective strategy to improve depression treatment by giving a new role to medicines that are already widely available.
