अगर आपको लगता है कि इस गर्मी में सनस्क्रीन लगाने से सूरज की तेज किरणों से आपकी त्वचा की रक्षा होगी, तो आपको फिर से सोचने की जरुरत है। इसके साथ ही आपको अपनी आंखों पर ध्यान देने की जरुरत है, अल्ट्रा वायलेट (यूवी) किरणें न केवल त्वचा के लिए हानिकारक हैं, बल्कि आंखों को भी नुकसान पहुंचा सकती हैं। शार्प साइट आई हॉस्पिटल्स के सीनियर कंसल्टेंट डॉ. दानिश इकबाल ने कहा, "यूवी एक्सपोजर को मैकुलर डिजनरेशन, मोतियाबिंद और अन्य ²ष्टि-हानि समस्याओं के साथ जोड़ा गया है।"
यदि आपकी आंख की मौजूदा स्थिति ठीक नहीं है जैसे आपकी आंखें लाल हो जाती हैं या फिर आपकी आंखों में मोतियाबिंद है, तो जितना हो सके गर्मियों के दौरान अपनी आखों का खास ध्यान रखें और आंखों को जितना हो सके धूप से बचाएं।
डॉ. दानिश ने इसको लेकर कुछ आसान टिप्स दिए जो गर्मियों में आपकी आंखों की सुरक्षा करेंगे।
धूप का चश्मा पहनें: 100 प्रतिशत पैराबैंगनी सुरक्षा धूप के चश्मे का प्रयोग करें। कठोर यूवी किरणें आपकी आंखों के लेंस, कॉर्निया और यहां तक कि रेटिना को भी नुकसान पहुंचा सकती हैं। इसलिए जब भी बाहर जाएं तो अपने शेड्स जरूर लगाएं।
आंखों को साफ पानी से धोएं: तेज गर्मी और धूप के संपर्क में आने से आपकी आंखें दिन भर तनाव में रहती हैं। समय-समय पर उन पर ठंडे पानी के छींटे मारे और अपनी आंखों को धोएं। यह आपकी आंखों को शुष्क या फूली हुई होने से बचाए रखेगा।
आंखों के व्यायाम करें: आंखों के व्यायाम से हमें थकान कम करने और आंखों की मांसपेशियों में सुधार करने में मदद मिलती है। रोजाना अपनी आंखों का व्यायाम करने से आपकी आंखों की रोशनी में भी सुधार होता है और बीमारियों और संक्रमणों के होने का खतरा कम होता है।
खीरे के स्लाइस का इस्तेमाल करें: अगर आपको गर्मियों में लाल आंखों से एलर्जी है, तो सोने से पहले 10 मिनट के लिए खीरे के स्लाइस को अपनी पलकों पर लगाएं। खीरा आंखों के नीचे से टैन हटाने में भी मदद करता है और अतिरिक्त नमी को अवशोषित करता है।
आंखों के लिए आई ड्रॉप का इस्तेमाल करें: दर्द को कम करने या आंखों की अन्य समस्याओं को प्रबंधित करने के लिए किसी प्रकार की आंखों की बूंदों का उपयोग करना हमेशा बेहतर होता है। हालांकि, आपको अपनी आई ड्रॉप चुनने से पहले किसी योग्य नेत्र रोग विशेषज्ञ से भी सलाह लेनी चाहिए।
हरी पत्तेदार सब्जियों का सेवन बढ़ाएं: गर्मी के मौसम में हरी पत्तेदार सब्जियों का सेवन बढ़ाएं क्योंकि वे ल्यूटिन और जेक्सैन्थिन दोनों से भरपूर होती हैं और आंखों के अनुकूल विटामिन सी का भी एक अच्छा स्रोत है। पत्तेदार सागों का इस्तेमाल करें।
अच्छी नींद लें: सोते समय आपकी आंखें अपने आप ठीक हो जाती हैं। अपर्याप्त नींद के कारण सूखी, खुजलीदार या पानी बहने वाली आंखें हो सकती हैं। रात में ठीक से नींद न लेने से आंखों में आंसू कम हो जाते हैं और इससे आंखों में संक्रमण का द्वार खुल सकता है। (एजेंसी)

UK researchers have developed a method to 'time jump' human skin cells by 30 years, turning back the ageing clock for cells without losing their specialised function.
The team from the Babraham Institute at University of Cambridge has been able to partly restore the function of older cells, as well as rejuvenating the molecular measures of biological age. Though the findings, published in the journal eLife, are at an early stage of exploration, it could revolutionise regenerative medicine.
The new method overcomes the problem of entirely erasing cell identity by halting reprogramming part of the way through the process. This allowed researchers to find the precise balance between reprogramming cells, making them biologically younger, while still being able to regain their specialised cell function.
In 2007, Shinya Yamanaka was the first scientist to turn normal cells, which have a specific function, into stem cells which have the special ability to develop into any cell type. The full process of stem cell reprogramming takes around 50 days using four key molecules called the Yamanaka factors.
The new method, called 'maturation phase transient reprogramming', exposes cells to Yamanaka factors for just 13 days. At this point, age-related changes are removed and the cells have temporarily lost their identity. The partly reprogrammed cells were given time to grow under normal conditions, to observe whether their specific skin cell function returned.
Genome analysis showed that cells had regained markers characteristic of skin cells (fibroblasts), and this was confirmed by observing collagen production in the reprogrammed cells.
"Our results represent a big step forward in our understanding of cell reprogramming. We have proved that cells can be rejuvenated without losing their function and that rejuvenation looks to restore some function to old cells," said Dr Diljeet Gill, a postdoc at the Institute.
"The fact that we also saw a reverse of ageing indicators in genes associated with diseases is particularly promising for the future of this work," Gill added. To show that the cells had been rejuvenated, the researchers looked for changes in the hallmarks of ageing.
Researchers looked at multiple measures of cellular age. The first is the epigenetic clock, where chemical tags present throughout the genome indicate age. The second is the transcriptome, all the gene readouts produced by the cell. By these two measures, the reprogrammed cells matched the profile of cells that were 30 years younger compared to reference data sets.
Further, the team tested the partially rejuvenated cells by creating an artificial cut in a layer of cells in a dish. They found that their treated fibroblasts moved into the gap faster than older cells. This is a promising sign that one day this research could eventually be used to create cells that are better at healing wounds.

Everything in the twenty-first century is easy-access whether it's the next show tickets or a place to crash for a weekend getaway. However, with the ease of information comes something even scarier, radiation! which we had no idea we were inadvertently ingesting. But somehow, we know that blue light can cause damage to our eyes and weaken our retinas, so imagine the amount of damage it can do to our skin. It can be really frightening!
We are surrounded by electronic devices such as mobile phones, computers, and laptops that emit radiation. But do we know what radiation is exactly? and what kind of damage it does do to the skin?
The cell phone you're using right now, or the laptop you're reading this article from, all have one thing in common, antennas. The antennas are chipped in to make a connection with the signal tower. These antennas as a form of connection emit radiation that harms our skin with time.
We all know, as informative as the digital world can be but there are times when it can be overwhelming us with misleading information. Namrata Bajaj, Co-founder, of Tatsa - Skincare made Simple helps us deep dive into the harms of radiation to our skin and how to protect it.
Skin Discolouration: All electronic devices have one thing in common, and that is the harmful radiation effect on the skin. Skin damage is a major phenomenon nowadays, radiation penetrating the skin causes itchiness, and dryness leading to skin discolouration by turning red or dark.
Premature Ageing: Given our current lifestyle of being around electronic devices all the time, our skin cycle is heading in the wrong direction. Radiations emitted from devices or the sun create tanning beds on our skin. Overexposure to UV rays harms the inner layer of tissues by making them lose their elasticity. Hence radiation leads us to premature ageing and such side effects.
The Breakouts: When our skin dislikes the environment around us, it showcases the same in different ways. Breakouts are one of the common problems noticed due to the environment. The skin loses its guards or becomes more sensitive, which eventually manifests itself in the form of breakouts.
Skin Pigmentation: Considering all of the skin damage caused by radiation and blue lights, skin pigmentation is one of the worst and possibly the most irritating skin conditions one adopts via radiation. As much as we want to avoid it, there is no escape, skin pigmentation is a condition where skin adopts darkening spots around the area.
Skin Sensitivity: As we age, skin sensitivity is one of the most significant factors that directly affect our skin and cause permanent damage to it, whether we get redness easily or dry skin all over it. Skin sensitivity weakens the strength of your skin, the more sensitive the skin, the less likely the skin is to fight against the harmful particles of the air. This is where the radiation enters the picture by weakening the skin to the point where it can no longer bear anything.
Dark Circles: Imagine the entire face is flawless and the red bags around the eyes sit rent-free! If you ask us, it's time to act upon the skin damage. No amount of good skin can cover the weightage of the heavy dark circles.
Namrata also suggests solution to protect our skin from radiation:
Allow your skin to absorb more than just radiation by getting out in the fresh air and allowing it to heal in nature.
There is nothing like drinking too much water; the more you drink, the more your skin will thank you. So, drink water and shield yourself from radiation with water.
Wash your face on a regular basis, and make sure your eyes are getting enough water so the harmful radiation is washed away with each splash.
Use a radiation protection face cream as your daily moisturiser to protect you from all types of radiation.
Lower down your screen timings. And don't use your phone during bedtime. (N. Lothungbeni Humtsoe)

Want to keep healthy and avoid the scorching summer heat, which is a common concern at this time of year?
The summer heat is not only physically exhausting and uncomfortable, but it also puts us at risk for ailments like skin irritation, rashes, fever, dehydration, and food poisoning. While the summer heat is enjoyable, it is vital that we do not disregard our health. Extra care must be made to battle the heat and stay fit and healthy during this season.
Consume Plenty of Water: Summer heat and sweat can dehydrate your body, resulting in unfavourable health outcomes such as fever and chills. Drink at least 2 to 3 litres of water per day to keep yourself hydrated.
Take Precautions to Avoid Heatstroke: Another major issue that older adults face during the hot summer months is heatstroke. The main reason that older adults are more vulnerable to this is that their bodies do not adjust to temperature changes as quickly. High fever, nausea, vomiting, headache, and dizziness are all common symptoms of heatstroke.
Light and Comfortable Attires: In the summer, it is best to dress in breathable and lightweight clothing to keep your body temperature regulated in the hot sun. Instead of heavy clothing, choose natural fabrics such as cotton and linen.
Indoor Stays Are Best: Outdoor activities should be limited to the cooler parts of the day, such as early mornings before 11 a.m. or late evenings after 5 p.m.
Eat Healthy And Light: Consume small, frequent meals. Heavy meals with high carbohydrate and fat content generate a lot of heat in the body. Concentrate on fresh fruits and vegetables with high water content, such as oranges, watermelon, tomatoes, and so on.
Protect Your Eyes: Wear protective eyewear to protect your eyes from the harsh sunlight at work and at play. When going outside, wear sunglasses that block at least 99 per cent of UV rays.
Avoid Alcohol And Caffeine: Alcohol, fizzy drinks, and coffee can all dehydrate you quickly. If at all possible, try to limit your intake of these popular beverages, especially during hot weather. A good substitute is a plain or flavoured water.(Olivia Sarkar)

London: UK researchers have identified a potential link between inflammation and the structure of specific regions of the brain, which may help in the treatment of neurodevelopmental psychiatric disorders including autism spectrum and schizophrenia.
According to the study, published in JAMA Psychiatry, the findings could open up a completely new target for the pharmacological treatment of these disorders, which has not significantly changed since the identification of antipsychotic medications in the mid-late 20th century.
Researchers at the University of Birmingham showed that genes associated with inflammation, particularly interleukin (IL) 6, are linked to a reduction in grey matter volume in certain areas of the brain known to be implicated in neuropsychiatric disorders.
In the study, the team was able to compare genetic variants which affect levels of IL-6, and other inflammatory genes in more than 20,000 patients with changes in grey matter volume in specific areas of the brain.
They were able to show strong links between IL-6 and brain structure particularly in the temporal and frontal regions.
Further analysis using the Allen Human Brain Atlas, showed that genes overexpressed in these areas are associated with conditions such as epilepsy, cognitive dysfunction, and schizophrenia.
"This study shows that the IL-6 gene, which we know to be linked to systemic inflammation, also affects brain structure in areas associated with these neuropsychiatric disorders. This could be the first new target for severe mental illnesses including schizophrenia identified in more than 60 years," said Professor Rachel Upthegrove, in the University's Institute for Mental Health.
Current treatments for these illnesses act on dopamine, a chemical messenger in the brain associated with mood and attention.
These drugs can have side effects, however, and they are not effective in all patients.
"There are drugs already on the market which target inflammation as well as the opportunity to screen potential new compounds. Finding a new avenue for exploring the links between inflammation, brain structure and neuropsychiatric disorders is really exciting," said John Williams, of the Institute for Cancer and Genomic Sciences at the University.

London: Genetic variants that damage the genome are associated with reduced reproductive success and an increased likelihood of not having children, suggests research.
According to researchers from the Wellcome Sanger Institute in the UK, one mechanism of natural selection that is removing damaging genetic variation from the population is increased childlessness.
It is likely linked to genetic influences on cognitive and behavioural traits, which may mean that men and women with these genetic variants are less likely to form reproductive partnerships.
However, the study, published in the journal Nature, also showed that this genetic link may play a very minor role in the overall likelihood of being childless. It accounts for less than one per cent when compared to more influential factors such as sociodemographic factors and choice.
In the study, the team included more than 340,000 participants, and investigated whether damaging genetic variants were associated with lower reproductive success by calculating for each person, how much damaging genetic variation they carry across their entire genome, known as their 'genetic burden'.
They tested whether genetic burden was associated with the number of children that the participants had, and found it was associated with men with the highest genetic burden having an average 0.26 fewer children - but this was not seen in women.
The team also found that increasing genetic burden was associated with a higher chance of being childless in both men and women, but much more so in men.
"It's important to emphasise that we have not found a 'gene for childlessness', as that implies a strong, causal effect of genetic variation on whether or not someone will have children. Instead we have shown that people with damaged genomes, particularly men, are slightly more likely to be childless," said Eugene Gardner at the MRC Epidemiology Unit at the University of Cambridge.
"This is probably due to the effect of damaging genetic variants on cognitive and behavioural traits, which make these men less likely to find a partner to have children with," said Gardner, who was at the Wellcome Sanger Institute while doing the research.
While the genetic burden is not associated with infertility, both men and women with a higher genetic burden were more likely to have mental health disorders. (agency)
