World Sunscreen Day: Everything you need to know about how sunblock works,from ideal SPF range to UV protection

On this day, let's take a closer look at sunscreen essentials. HT Lifestyle reached out to experts to help you understand how to protect your skin effectively, from knowing how sunscreen works, SPF requirements, to sunscreen for children.
First, let's break down how sunscreen works. Dr Shifa Yadav, Consultant, Dermatology and Cosmetology at Artemis Hospitals, unpacked the science behind sunscreen and what SPF truly means for your skin.
She said, 'Sunscreens can be regarded as an invisible shield your skin uses to defend itself from harmful sun rays. Their usage is not restricted to only tanning prevention; rather, their key purpose is to avoid any form of damage the skin could receive. Sunscreen is a shield for your skin, forming a layer that blocks or reflects the damaging ultraviolet rays of the sun, especially the UVB rays, so well researched to cause sunburns and greatly enhance the risk of skin cancer."
Moreover, Dr Shifa Yadav shared a detailed guide on how much SPF is enough:
Now that we are done with SPF, you may have probably come across the term broad spectrum as well. One common misconception is that people often focus mostly on the SPF number when choosing a sunscreen. But true protection lies in a combination of both SPF and broad-spectrum coverage.
Malini Adapureddy, CEO & Founder of skincare brand, Deconstruct, explained, "The most effective sunscreen is one that offers broad-spectrum protection against both UVA and UVB rays. While UVB rays cause visible burns, it is the deeper-penetrating UVA rays that silently accelerate ageing and pigmentation. In a country like India, where sun exposure is high year-round, this dual protection is non-negotiable. Many people focus on SPF numbers alone, but the real measure of protection lies in how comprehensively a sunscreen defends the skin. Broad spectrum isn't a luxury, it is the minimum standard for maintaining long-term skin health."
With so much conversation around sunscreen being an absolute unskippable daily essential, what about children? More than adults, children are vulnerable to sun damage because of their sensitive skin. Which sunscreen is most suitable for children? Should your children even apply sunscreen?
Dr Mikki Singh, Founder and Head Dermatologist at Bodycraft Clinics and Salon, firmly emphasised the importance of sunscreen for children. She said, 'Yes, children should absolutely use sunscreen. Early sun protection helps prevent sunburn, long-term skin damage, and lowers the risk of skin cancer later in life.'
Dr Singh shared a guide for parents, helping them to guide sunscreen use for children:

Oncologist shares 6 causes of sarcoma cancer: Age, gender, genetics and more
Sarcoma is a rare but aggressive type of cancer that develops in the connective tissues of the body, such as bone, muscle, fat, cartilage, and blood vessels. A mix of lifestyle, environmental and genetic causes are responsible for this type of cancer. In an interview with HT Lifestyle, Dr Rajesh Kumar Jain, principal director, surgical oncology, BLK-Max Super Speciality Hospital shared the 6 main causes that can lead to sarcoma cancer. Also read | Sarcoma Awareness Month: Oncologist explains 5 treatment options for soft tissue sarcoma Know the main causes that can lead to sarcoma cancer. (Anna Tarazevich) 1. Genetic mutations One of the primary causes of sarcomas are genetic mutations, whether inherited or acquired. Certain hereditary conditions significantly increase the risk of developing sarcomas. These include Li-Fraumeni syndrome, neurofibromatosis type 1 (NF1), and familial retinoblastoma. These syndromes are characterised by mutations in tumor suppression genes whose normal cellular function is to regulate growth and which disable the protective function of preventing tumors. When these tumor suppression genes are mutated, the cells are freed to grow uncontrollably, resulting in sarcoma. 2. Radiation exposure Radiation exposure is another well-documented cause. People who have undergone radiation therapy for other cancers may develop sarcomas in the treated area, sometimes years after the original treatment. These are known as radiation-induced sarcomas. The risk is relatively low but significant enough to be a known concern for cancer survivors. 3. Environmental exposure Environmental factors contribute, but not to the same extent. Certain chemicals—like vinyl chloride (used to make plastics), arsenic, and herbicides—have some relationship with certain sarcoma subtypes when exposure is done over time. Certain long-term environmental exposures have a less specified association to sarcoma; in addition, such links are mostly occupational. Also read | Is sarcoma cancer always fatal? Oncologist debunks 7 myths related to cancer that develops in bones and muscles Exposure to radiation therapy can increase the risk of sarcoma cancer.(Unsplash) 4. Lymphedema Long standing Lymphedema (swelling which is caused by accumulation of lymphatic fluid in body) after breast cancer surgery, is a well-established risk factor for a type of sarcoma called angiosarcoma. Chronic inflammation in the lymphedematous area is believed to promote tumor formation, though the exact mechanisms remain unclear. 5. Injury or trauma Trauma or injury has often been speculated as a cause, but there is no strong scientific evidence to support a direct link between physical injury and sarcoma development. In many cases, a sarcoma may have already been present and only discovered following an injury to the area. 6. Age and gender Age and gender may also be related to risk factors. Although sarcomas can occur at any age, certain types are more common in children and young adults, including, but not limited to, Ewing sarcoma and rhabdomyosarcoma. Other types, such as liposarcoma, tend to be more common in older adult populations. Some studies also show a slight increase in incidence in males compared to females.

Does summer heat affect your fertility? Here's what IVF expert says: ‘Might seem logical but…'
When it comes to fertility and assisted reproductive techniques like IVF (In Vitro Fertilization), hopeful couples often find themselves navigating a maze of information, assumptions and myths. One commonly held belief is that the summer season negatively impacts pregnancy chances or lowers IVF success rates. Worried about starting IVF in the summer heat? Read this before you delay.(Image by Pixabay) In an interview with HT Lifestyle, Dr Rachita Munjal, senior consultant – fertility at Cloudnine Group of Hospitals in Gurgaon, shared, 'IVF success rates depend upon egg quality. The idea that seasonal shifts can affect fertility outcomes might seem logical on the surface but science tells a different story.' The science behind IVF: A controlled environment IVF is a highly advanced medical process that occurs in a controlled lab environment, far removed from external weather conditions. Dr Rachita Munjal explained, 'Embryos are fertilized and cultured in laboratories where temperature, humidity, and air quality are tightly monitored. These artificial conditions are designed to mimic the optimal environment for embryo development — regardless of whether it is sweltering summer or freezing winter outside.' IVF has been helpful even in cases where a natural pregnancy is medically not possible. She added, 'Thus, the belief that the external climate could affect embryo health or success rates is scientifically unfounded. IVF success depends more on medical protocols, age, ovarian reserve, sperm quality and overall reproductive health than it does on the season.' Statistical evidence: No seasonal variation in IVF outcomes Numerous studies have compared IVF success rates across different seasons. The results? No significant variation has been found. Dr Rachita Munjal revealed, 'Fertility clinics worldwide have analyzed thousands of cycles to assess whether birth rates, implantation rates, or embryo quality differ from season to season. The consensus is clear: seasons do not determine the success of IVF treatments. This should be reassuring for couples who are mentally and physically ready for IVF. There is no need to delay or plan treatment around specific months unless advised otherwise by a medical professional for personal health reasons.' How summer may actually support fertility Interestingly, Dr Rachita Munjal pointed out that some biological factors associated with summer could even enhance fertility and IVF outcomes. 1. Vitamin D Boost: Sunlight is the most natural source of Vitamin D, a nutrient essential for reproductive health. Vitamin D plays a critical role in: Regulating hormones Improving ovarian function Enhancing sperm quality Supporting embryo implantation and pregnancy maintenance Several studies have shown a correlation between adequate Vitamin D levels and improved IVF success rates. During the summer, with longer days and increased sun exposure, the body naturally produces more Vitamin D. This natural boost can benefit both men and women trying to conceive. If you are preparing to embrace motherhood soon, you need to make sure you are consuming the right nutrients from iron, folate, calcium, vitamin D, to protein. Dr. Madhuri Roy, Gynaecologist & IVF Consultant, Founder, and Managing Director of Conceive IVF, Pune gives you diet tips.(Pixabay) 2. Melatonin Regulation: Melatonin, a hormone secreted by the pineal gland, is best known for its role in sleep regulation. However, it also plays an important role in reproductive health, especially in protecting eggs and embryos from oxidative stress. Seasonal variations in melatonin production — which tend to stabilize in summer — may contribute positively to overall fertility. Combined with good sleep hygiene and healthy lifestyle habits, summer may provide an internal hormonal environment that is conducive to conception. Planning IVF: What really matters Rather than worrying about external weather patterns, Dr Rachita Munjal said couples should focus on what truly influences IVF success: Maternal age Quality of eggs and sperm Uterine receptivity Embryo quality Lifestyle factors like diet, sleep, and stress Medical expertise and technology used at the clinic Emotional readiness and mental well-being are also key. Undergoing IVF can be an emotionally intense experience. Choosing a time when you feel psychologically prepared can make a meaningful difference in your journey — and for many, the calm and routine of summer may offer that space. When is the best time to start IVF? Dr Rachita Munjal answered, 'The best time is when you are ready — not based on the calendar, but on your health, doctor's advice, and emotional preparedness. If your fertility specialist has assessed your condition and recommended treatment, there is no need to postpone IVF based on the season. It's also important to remember that IVF success often takes time and depends on factors outside anyone's control that can affect outcomes. What matters is having trust in the process, your care team and your body.' Don't let myths guide medical decisions In the age of information overload, it's easy to fall into the trap of believing myths and hearsay — especially when you're on a deeply personal journey like fertility treatment but letting such myths influence important medical decisions can do more harm than good. Dr Rachita Munjal pointed out - There's no scientific proof that summer reduces IVF success. IVF labs maintain optimal, controlled environments. Sunlight and melatonin may even support reproductive health. Emotional readiness is more important than external temperature. So if you're planning to start IVF or are in the midst of your treatment, know this: you don't need to wait for the 'perfect season.' Instead, focus on your physical, emotional and mental health — and trust the science. Miracles take time, and each fertility journey is unique. Stay hopeful, stay informed and move forward with confidence. Note to readers: This article is for informational purposes only and not a substitute for professional medical advice.
