Winter has arrived, bringing with it dry, flaky skin and hair. Frizzy, lifeless, and damaged hair, as well as dry skin, cannot be blamed only on the winters. Our skin and hair are influenced by many different things, like the ultraviolet radiation from the sun or pollution, particularly pollution from cities.
One of the worst enemies of skin and hair is pollution. Established industries, car emissions, and cigarette smoking all contribute to rising pollution levels. The most harmful pollutants are particulate matter (PM), which includes PAHs (polycyclic aromatic hydrocarbons) and poisonous gases like SO2, NO2, NO, CO2 and CO2.
"The exposure to smoke, dust, toxic gas, particulate matter, nickel, lead and arsenic can lead to a condition called 'Sensitive Scalp Syndrome', which happens when this particulate matter settles on the scalp and in the hair shafts.""Pollution exposure can cause chemical damage to the hair. It leads to degrading hair protein, affects the hydrophilic hair surface niche and damages the hair cuticles."
"According to a recent research, Intense exposure to the pollutants also affects the skin, reduces the stratum corneum (outer skin layer) quality, increases the dark spots, intensity wrinkles, fine lines and affects the normal composition of natural sebum production."
"Pollution exposure, particularly PM, VOCs (volatile organic compounds) and PAHs are also known to inflame the skin, increases the oxidative stress in the skin and working synergistically with harmful sun rays, these pollutants can be one of the main reasons of skin cancer."
All these facts are enough to understand how dangerous and detrimental pollution is for our skin and hair. We need to take some proper precautions to protect our hair and skin from this natural enemy. Here's a list of some of the best pollution skincare and hair care suggestions for you today:
Skin Care Tips
Applying Broad-Spectrum Sunscreen Every Day is Important
A broad-spectrum sunscreen with the power of antioxidants is the right option for your skin to protect it from the effects of pollutants. A broad-spectrum sunscreen gives your skin a shield against UVA, UVB, and IR rays. However, the richness of antioxidants in a sunscreen provides full protection from pollution. This is why you don't apply sunscreen even a single day throughout the year.
Must Cleanse The Face After Returning The Home
We rinse our face in the morning for freshness, but in the evening cleansing, the face not only provides you with freshness but also a big relief from dust, grime, and pollutants. Select charcoal-based or active ingredients like vitamin C or retinol-based serums to deeply cleanse your skin from the particles of pollutants. Never skip this step, no matter how tired you are. For healthy skin, this step is a must.
Give Your Skin The Night Skin Repair Therapy
The other thing you need to include in your night skin care routine is a good repair face serum or cream. Retinol, vitamin C or ferulic acid-based face serums are best to repair polluted skin. These ingredients are rich in antioxidants, which help to neutralise free radicals, reduce oxidative stress and reduce pollutant-induced skin damage.
Go For A Home-Based Detox Face Pack Every Week
There is an ultimate DIY detox face pack that you will love to apply to your face, especially if you are a chocolate or coffee lover. You'll need cocoa powder and ground coffee beans for this pack.
These two ingredients contain the best antioxidants to cleanse the face. Take both ingredients in an equal quantity and add coconut oil or milk to make a fine paste. Add honey if you want to, and apply it to your face. Let it dry and rinse your face with normal water. Apply a moisturiser afterwards.
Hair Care Tips
Cover your hair with cloth or hat when outside
Whenever outside, make sure to cover your hair with a cloth or a hat, as it will hinder the direct contact of pollutants with your hair. In the winter, this may be the best option.
Don't Forget to Apply A Good Hair Serum
If you are unable to cover your hair, you must apply a hair protecting serum before going out. It forms a thin covering layer over your hair and protects it from toxic gases and other urban pollutants. The hair serum not only gives shine to the hair but also works as a protector of the hair and keeps it intact from pollution and heat.
Rinse The Hair Every Two to Three Days
Make sure to rinse your hair every 2 to 3 days, especially if you live in an area with high pollution levels. It will clear up all the dirt and pollutants from your scalp, and you can flaunt healthy, wavy, luscious hair.
Give Your Hair A Keratin Spa or Keratin Mask
Pollutants can also impact hair protein levels. To restore it, you should go to a keratin spa at home using a good hair mask. For this, you need 1 tablespoon of almond oil, 1 tablespoon of honey, and 1 egg yolk. Mix the ingredients and apply the paste on the overall scalp and hair. Keep it for about an hour and shampoo the hair.
These tips can protect you from pollution and revive your skin and hair to maintain their natural essence. Along with these, you must add antioxidant-rich foods like citrus fruits, broccoli, spinach, onions, garlic, and turmeric to revive skin and hair from the inside.

A team of Israeli researchers have identified five proteins in the SARS-CoV-2 virus that are responsible for severe vascular damage that could lead to heart attack or stroke.
While Covid-19 is largely known as respiratory disease, there has been a very high incidence of vascular disease and blood clotting, for example stroke and heart attack, among Covid patients.
Researchers from Tel Aviv University identified the five proteins from a total of 29 different proteins that make up the novel coronavirus. When the coronavirus enters the body, it begins to produce 29 proteins, the team said.
In the process of infection and the protein development, the "blood vessels turn from opaque tubes into kind of permeable nets or pieces of cloth, and in parallel there is an increase in blood clotting", said Dr Ben Maoz, Afrom the varsity's Department of Biomedical Engineering and Sagol School of Neuroscience.
The team thoroughly examined the effect of each of the 29 proteins expressed by the virus, and were successful in identifying the five specific proteins that cause the greatest damage to endothelial cells and hence to vascular stability and function.
"We tend to think of Covid as primarily a respiratory disease, but the truth is that coronavirus patients are up to three times more likely to have a stroke or heart attack. All the evidence shows that the virus severely damages the blood vessels or the endothelial cells that line the blood vessels. However, to this day the virus has been treated as one entity. We wanted to find out which proteins in the virus are responsible for this type of damage," Maoz said.
In the study, published in the journal eLife, the team used the RNA of each of the Covid-19 proteins and examined the reaction that occurred when the various RNA sequences were inserted into human blood vessel cells in the lab.
In addition, the team used a computational model which allowed them to assess and identify which coronavirus proteins have the greatest effect on other tissues, without having seen them 'in action' in the lab.
"Our research could help find targets for a drug that will be used to stop the virus's activity, or at least minimise damage to blood vessels," Maoz noted. (Agency)

Chennai, Aug 10 (IANS) After a third renal transplant surgery, a 41-year-old resident of Chennai now has five kidney's in his body and is doing well.The patient, who underwent a third renal transplant surgery at the Madras Mission Hospital, earlier had two transplanted kidneys in his body along with his original two kidneys.This is one of the rarest of procedures conducted on a patient, which is not common even globally.The surgery was performed on the patient on July 10 and exactly after a month during his first check-up post the operation, the doctors found that he was keeping well, and his transplanted kidney was functioning properly.The vascular and transplant surgeon who performed the surgery on the patient, Saravanan, told IANS, "There were four challenges in performing this surgery -- first, lack of space for the new kidney in the retroperitoneum; lack of width on the native blood vessels to connect the renal artery and vein; the bladder was scattered with earlier surgeries; and the patient tended to develop a lot of antibodies from the earlier surgeries and plasmapheresis (filtering the blood) had to be performed before placing the new kidney."He also said that the reason the old kidneys have not been removed to make space for the new one is because the patient could profusely bleed and require blood transfusion and could lead to the production of antibodies and rejection of the new kidney.The 41 year old patient had hypertension and chronic kidney disorder (CKD) and had two earlier failed renal transplant surgeries owing to uncontrolled hypertension. The patient had also undergone triple bypass surgery at the Madras Medical Mission Hospital three months back, after he was diagnosed with coronary artery disease.Saravanan said, "The kidney was placed high above in the abdominal cavity, right next to the intestine as opposed to the conventional approach. The transperitoneal approach (through the gut), a rare surgery, saved the day for my patient. This is an uncommon surgery and I have to see a paper published on this in India."--IANSaal/arm
London, Aug 6 (IANS) A team of scientists have identified an experimental drug that may help prevent Covid-related heart damage.Scientists at the University of Cambridge grew heart cells in the lab using human embryonic stem cells, to understand how the virus infects the heart cells. Crucially, these model heart cells also contained the key components necessary for SARS-CoV-2 infection -- in particular, the ACE2 receptor.Using the model, they identified an experimental peptide drug called DX600 which can prevent the virus from entering the heart cells. The findings are published in the journal Communications Biology."Using stem cells, we've managed to create a model which, in many ways, behaves just like a heart does, beating in rhythm. This has allowed us to look at how the coronavirus infects cells and, importantly, helps us screen possible drugs that might prevent damage to the heart," said Dr Sanjay Sinha from the Wellcome-MRC Cambridge Stem Cell Institute.The team showed that some drugs that targeted the proteins involved in SARS-CoV-2 viral entry significantly reduced levels of infection. These included DX600 -- an ACE2 peptide antagonist which is a molecule that specifically targets ACE2 and inhibits the activity of peptides that play a role in allowing the virus to break into the cell.DX600 was around seven times more effective at preventing infection compared to the antibody, though the researchers say this may be because it was used in higher concentrations. The drug did not affect the number of heart cells, implying that it would be unlikely to be toxic."The spike protein is like a key that fits into the 'lock' on the surface of the cells -- the ACE2 receptor -- allowing it entry. DX600 acts like gum, jamming the lock's mechanism, making it much more difficult for the key to turn and unlock the cell door," said Professor Anthony Davenport from the Department of Medicine and a fellow at St Catharine's College, Cambridge.He added that further research is needed on this drug, "but it could provide us with a new treatment to help reduce harm to the heart in patients recently infected with the virus, particularly those who already have underlying heart conditions or who have not been vaccinated." It may also "help reduce the symptoms of long Covid".--IANSrvt/vd
New Delhi, July 8 (IANS) The Ministry of AYUSH has rejected a study published in the Journal of Clinical and Experimental Hepatology, a peer reviewed journal of the Indian National Association for the Study of the Liver.
This study mentions that use of the herb Tinospora Cordifolia (TC), commonly known as 'Giloy' or 'Guduchi', resulted in liver failure in six patients in Mumbai.
The ministry said "the authors of the study failed in placing all needful details of the cases in a systematic format. Apart from this, relating Giloy or TC to liver damage would be misleading and disastrous to the traditional medicine system of India as Guduchi or Giloy has been used in Ayurveda since long. The efficacy of TC in managing various disorders is well established."
"It becomes the responsibility of the authors to ascertain that the herb consumed by the patients is TC and not any other herb. To build upon the soundness, the authors would have taken the opinion of a botanist or would have consulted an Ayurveda expert.
"In fact, there are many studies that point out that not identifying the herb correctly could lead to wrong results. A similar looking herb TinosporoCrispa might have a negative effect on the liver. So, before labelling a herb such as Giloy with such toxic nature, the authors should have tried to correctly identify the plants following the standard guidelines, which they did not," the ministry said.
Publications based on "incomplete information" will open the door for misinformation and defame the age-old practices of Ayurveda, the ministry said.
"It would not be out of context to state here that scientific evidence on medical applications of TC or Giloy as protective to liver, nerves etc. is available," it said.
"There are other hundreds of studies on Giloy and its safe use. Giloy is one of the most commonly prescribed medicines in Ayurveda. It has proper pharmacopoeia standards in place for established safety of hepatoprotective properties. No adverse event is noted in any clinical practice by pharmacovigilance or in any clinical study," it said.

<br>In an exclusive interaction with IANS, Institute of Genomics and Integrative Biology Director, Dr Anurag Agrawal, explained in detail about 'Delta' and 'Delta plus' Covid-19 viruses and their possible effect in the subsequent wave of pandemic."Regions that have already suffered from Delta outbreaks should not have a major problem with Delta plus, since I expect there to be reasonable cross-neutralisation of Delta plus by antibodies raised against Delta. Thus, I do not see an immediate threat or any reason to panic," he said, adding that Delta plus is not rising faster than Delta in the previous month, so that is confirmation of sorts.On what Delta variant is exactly and why it has become a "variant of concern" amid this Covid pandemic, he said that it Delta virus is a mutant variant of SARS-Cov-2 or B.1.617.2, which is known as Delta variant. It has mutations in its spike protein, which makes it more transmissible and able to evade immunity."It has already spread to 80 countries across the world. After India, now it is spreading fast in the UK, in some states in the US, in Singapore and southern China," he added.Agrawal explained that the Delta plus variant of Covid-19 is a mutation of Delta variant, adding when Delta variant develops additional mutations of possible importance, it is called Delta plus."However, this is not a Delta/Beta hybrid, but a case of convergent evolution where mutations develop independently. We can also call it AY.1 or AY.2," he clarified.On the possibility of third wave of Covid-19 pandemic as has already predicted by the Union Health Ministry and the possibility of effect of Delta plus variant during the period, Agrawal said: "At present, everyone want to know when there will be the next surge, but I don't think it will come anytime soon as the Delta variant caused this surge across the country. Majority of people will have immunity against it right now. So while I expect localised outbreaks, I don't expect a big national wave anytime soon."He said any outbreak begins by infecting the most exposed or vulnerable population in an area and then spreads by infecting more and more people who are susceptible. It can be controlled only through following Covid appropriate behaviour strictly and vaccination, he stressed."Of course, if the virus mutates drastically to evade this immunity, and more importantly if people lower their guard as they did a few months back, there could certainly be another wave," he said. Asked how does mutation impact the efficacy of the vaccines, Agrawal contended that some mutations on the virus's spike may not allow the antibodies developed after immunisation to bind to it. In such cases, the mutant can escape the immunity and cause disease. However, the fact has emerged that so far, available vaccines are efficient to prevent severe disease by mutants but have reduced effectiveness in preventing infection.--IANS<br>pd/vd
