Blue light emitted by devices like smartphones, computers, and televisions is becoming a major factor disrupting our sleep cycles. Research reveals that a significant number of Americans use electronic devices close to bedtime, contributing to poor sleep quality. Reducing exposure to blue light, particularly in the evening, is a simple yet effective way to help your body prepare for restful sleep.

What Is Blue Light?

How Does Blue Light Impact Circadian Rhythms?

Circadian rhythms are 24-hour cycles that control essential bodily functions, including sleep. Light is the primary factor that aligns these rhythms with day and night. Historically, exposure to sunlight during the day helped set our body clocks, signaling when to be awake and when to sleep. However, the widespread use of artificial lighting and electronic devices has introduced more light exposure after dark, disrupting these natural cycles.

Blue light, in particular, has the strongest impact on circadian rhythms. During daylight hours, blue light helps us feel alert by stimulating the brain, raising body temperature, and increasing heart rate. But in the evening, exposure to blue light can confuse the body’s internal clock, suppressing melatonin—the hormone responsible for making us feel sleepy. As a result, our brains may remain in “daytime mode,” preventing us from winding down for the night.

Health Consequences Of Disrupted Sleep

Persistent disruption of circadian rhythms can lead to a range of health issues, including metabolic disorders, poor mental health, and increased risk for conditions like depression and anxiety. Furthermore, the inability to sleep well at night affects cognitive performance, mood, and overall well-being. Chronic exposure to blue light in the evening may significantly contribute to these negative health outcomes.

Devices That Emit Blue Light

Many common devices in our daily lives emit blue light, including:

- Smartphones and tablets

- Computer monitors and laptops

- Televisions and e-readers

- LED and fluorescent lighting

- Video game consoles

How To Minimize Blue Light Exposure

To reduce the effects of blue light on your sleep, here are some practical strategies:

1. Turn off screens before bed: Try to avoid using electronic devices at least two to three hours before bedtime. Reducing screen time helps prevent blue light from interfering with melatonin production.

2. Adjust your lighting: Dim your home’s lights or switch to warmer-toned lighting in the evening. You can also use lamps with red or orange light, which are less likely to impact your circadian rhythms.

3. Night mode settings: Many smartphones and computers have a "night mode" feature that reduces blue light emission. Make use of these features to limit exposure in the hours leading up to bedtime.

4. Blue light-blocking glasses: Special glasses designed to filter out blue light may be helpful for some individuals. These glasses can block or reduce the melatonin-suppressing effects of blue light.

5. Apps for blue light reduction: There are several smartphone and computer apps available that reduce blue light emission, allowing you to use your devices before bed without disturbing your sleep.

6. Create a sleep-friendly environment: If you can’t control light sources in your bedroom, consider using an eye mask to block out ambient light and promote better sleep.

The journey of a breast cancer patient does not end when their treatment comes to a conclusion. There is always a risk of recurrence, which makes regular follow-ups and adherence to treatment important.

At the Times Network India Health Summit and Awards 2026 in New Delhi, a panel formed by Dr Priya Parmar, Chief Operating Officer, Indian Cancer Society, Delhi, Dr. Jyoti Wadhwa - Principal Lead of Medical and Precision Oncology, Apollo Athena Women’s Cancer Centres, New Delhi and Apollo Hospital, Gurgaon, Dr. Meenu Walia, Chairman Medical Oncology, Max Healthcare, Dr Pankaj Goyal, Sr Consultant and Unit Head, Medical Oncology, RGCI, and Vaishali Iyer, Country Head, Communications, Patient Advocacy and CSR, Novartis in India, discussed the big picture after breast cancer treatment.

During a panel discussion titled “Take Charge Together: Shaping a Future of Greater Breast Cancer Awareness and Better Outcomes,” experts highlighted the physical, emotional, social and financial challenges that women may continue to face after treatment among many more.

What Comes After Breast Cancer Treatment?

For many women, the period after breast cancer can involve more than medical monitoring. They may face fatigue, menopausal symptoms and changes in body image after undergoing a major physical change, while concerns about intimacy, fertility and relationships can affect emotional and mental well-being.

Dr. Priya Parmar highlighted how losing a breast or hair can affect a woman's sense of identity and femininity. Some survivors also face social stigma related to marriage and fertility, while sexual health and relationship concerns may remain difficult to discuss.

The burden can be greater for women who lack family support or have limited financial resources. These circumstances may affect not only emotional recovery but also their ability to attend follow-up appointments and continue treatment.

The financial strain can become particularly difficult if cancer returns and further investigations or treatment are required.

Dr. Meenu Walia said that treatment for advanced disease can add to the economic burden faced by patients and their families.

Risk Of Recurrence

The risk of breast cancer recurrence is not the same for every patient. It depends on the cancer's stage and subtype, tumour grade, lymph node involvement, response to treatment and whether treatment is timely.

Dr. Jyoti Wadhwa explained that different breast cancer subtypes can follow different recurrence patterns.

Triple-negative breast cancer tends to recur earlier, often within the first two to three years after treatment. Hormone receptor-positive, HER2-negative breast cancer, however, can return even 10 to 20 years later.

She also said that patients who achieve a pathological complete response after treatment given before surgery may have a lower risk of recurrence than those with residual disease.

However, a lower estimated risk does not mean the risk is eliminated. Continued monitoring is important even for patients who have responded well to treatment.

Feeling Better Is Not A Reason To Skip Follow-Ups

One concern raised by the experts was that some patients stop taking prescribed oral hormone therapy or miss appointments after their symptoms improve.

“Your first attempt at treatment is always your best attempt,” Dr. Walia said, underlining the importance of appropriate diagnosis and treatment from the outset.

Follow-up care helps doctors monitor a patient's recovery, assess treatment-related effects and make decisions based on individual clinical circumstances. The appropriate schedule and any further treatment depend on the patient's diagnosis, risk profile and medical history.

Experts also cautioned against allowing the possibility of recurrence to dominate a survivor's life. Understanding individual risk should help patients make informed decisions, rather than leave them in constant fear that cancer will return.

Post-Treatment Care Needs More Than Medical Monitoring

The long-term effects of breast cancer also have implications beyond the individual patient. Vaishali Iyer, Country Head of Communications, Patient Advocacy and CSR at Novartis in India, highlighted an estimated 140 million productive hours lost due to breast cancer care, drawing attention to its wider economic impact.

Dr. Wadhwa emphasised the need to address treatment-related concerns, including menopausal symptoms and bone health, which may require attention even after primary cancer treatment has ended.

Dr. Pankaj Goyal, Senior Consultant and Unit Head of Medical Oncology at RGCI, stressed that doctors must build trust with patients and explain recurrence risks without causing unnecessary alarm. Discussions about care should also account for patients' personal circumstances and financial constraints.

The panel discussion, titled “Take Charge Together: Shaping a Future of Greater Breast Cancer Awareness and Better Outcomes,” took place at the Times Network India Health Summit and Awards 2026.

Padma Bhushan Dr Shiv Kumar Sarin, leading hepatologist, gastroenterologist, and medical educator who also serves as the Senior Professor, Chancellor, and Director of the Institute of Liver and Biliary Sciences (ILBS), recently spoke about the dos and don’ts to maintain a healthy liver at the Times Health Summit 2026.

Held under the theme “The Blueprint for a Future-Ready Healthcare Ecosystem – Innovation. Access. Self-Reliance,” the summit brought together healthcare professionals and industry stakeholders to discuss innovation, access to treatment and policy approaches shaping India's healthcare sector.

Should You Drink Hot Water In The Morning For Bowel Movement?

The doctor addressed the daily morning ritual of drinking hot water in the morning, which a lot of people follow to release bowels.

Dr Sarin said, “Don't use hot water or anything for that matter to make you go to the toilet because it is the connection between the brain and the bowel that is very important.

He also spoke about opting for other drinks like coconut water or lemon water with honey. He said that lemon can help improve iron absorption in your body.

He added, “As per coconut water is concerned, it has potassium which is very good for your bowel health but it should still not be an everyday thing. For nimbu and honey, you should remember that honey has fructose. So if you are consuming honey, you also need to churn that out."

Ideal Time for Breakfast

Many of us do not know what is the right time for breakfast. It is especially important as eating after fasting for eight to ten hours affects your energy and metabolic health throughout the day.

Dr Sarin said, "It's after sunrise. Minimum 12 hours after the last food that you have eaten. Ussay pehle galti nahi kariyega khaanay ki. Let the stomach, and the bacteria and the intestine recover."

He also spoke about whether you should have fruits for breakfast. "Breakfast should be fruits. And, low calories fruits. Avoid carbs."

How Coffee Affects The Liver

There is a lot of information as well as misinformation about coffee consumption and liver health. Dr S K Sarin spoke in its favour and said that it could prevent a lot of liver conditions.

He said, "It does many things. it clears several toxic things including fat, clears the flow of bile, good enzyme inducer, prevents fibrosis of the liver and can decrease cirrhosis and also the development of liver cancer."

He also warned ignoring healthy dietary habits and simply relying on coffee is also not ideal. He added, "Coffee is not medicine, it is something which can help you prevent and not treat."

Is Your Lunch Completely Healthy?

Dr Sarin also warned against eating more amount carbohydrates than the recommended limit. He explained how sitting next to an obese person can make you feel physically lethargic as their breath may emit endogenous alcohol.

When you eat a carbohydrate-heavy meal, your digestive system breaks down carbohydrates into sugars. Certain microorganisms in the gut, including yeasts and some bacteria, can ferment these sugars and produce small amounts of ethanol, or alcohol. This is known as endogenous alcohol production.

Dr Sarin recommends eating low-carb meals for lunch like sprouts, vegetables, yoghurt, buttermilk or low-sugar fruits.

Late-Night Eating Is A Red Flag

Dr Sarin recommends having dinner before sunset. He also said that having late-night dinners could disrupt your sleep.

He added, "Obesity during youth increases the risk of heart disease later in life. After the age of 40, eating one meal a day may have health implications. The total daily calorie intake should not exceed 300–400. Avoid eating late at night. Eating late can also affect your insulin resistance."

Yearly Screening To Keep Liver Health In Check

Dr Sarin also said that thin people can also have unhealthy fat that may cause fatty liver. He recommended yearly screens to keep liver health in check.

He said, "Even thin people can have excess body fat and low muscle mass, which may affect their health. Being thin does not necessarily mean being healthy. Maintaining good muscle mass is important."

In a significant step toward advancing xenotransplantation—the transplantation of organs or tissues from animals into humans—in India, a dedicated department has been established, with research and regulatory work underway. The country’s first animal-to-human organ transplant could follow, subject to government approval and the establishment of legal and ethical guidelines.

The initiative aims to help bridge the organ shortage in the country, Dr. Shikhar Tripathi, Director of the Department of Xenotransplantation Sciences at Sir Ganga Ram Hospital, New Delhi, helming the project, told HealthandMe.

Dr. Tripathi, who has trained with Dr. David K. C. Cooper, a British surgeon-scientist and pioneer of modern xenotransplantation, believes India could perform its first xenotransplant within six months of receiving government permission.

The push comes as xenotransplantation continues to make progress internationally. In 2025, a patient received a genetically engineered pig kidney and lived without dialysis for 271 days before subsequently receiving a human kidney transplant.

India recorded 20,138 organ transplants in 2025, ranking third globally. However, the gap between the demand for and supply of organs remains significant, with deceased-donor donations accounting for a small share of transplants.

Dr. Tripathi estimates India’s annual organ shortage at around 90,000. According to data reported by hospitals and transplant centers on the National Organ and Tissue Transplant Organization (NOTTO) National Registry Portal, the waiting list for major organs stood at 89,839 as of March 3, 2026.

Kidneys accounted for the largest share of patients on the waiting list, followed by livers, hearts, lungs and pancreases.

In an interview with HealthandMe, Dr. Tripathi, who is also working with Dr. Cooper at the Thomas E. Starzl Transplantation Institute in Pittsburgh, US, discussed the scientific barriers, infection risks, regulatory requirements and potential of xenotransplantation in India.

Q. A pig kidney functioned for 271 days without dialysis in a human. What does this milestone mean for xenotransplantation?

Dr. Shikhar Tripathi: Xenotransplantation has achieved significant milestones, but researchers are still working toward long-term viability. For now, it could serve as a bridge for patients who need an organ while researchers work to address complications and improve graft survival.

“Xenotransplantation has achieved some really significant milestones in the last year or so.”

Q. What are the main barriers to long-term survival of a transplanted animal organ?

Dr. Tripathi: Genetic engineering has helped researchers modify the pig genome to reduce the risk of early rejection. The challenge now is managing late complications, particularly in kidney xenotransplantation.

Two major concerns are proteinuria, or leakage of proteins through the kidney, and thrombotic microangiopathy (TMA), which involves injury to microscopic blood vessels.

“The current barrier we face is late complications of xenotransplantation.”

He added that his group has published research identifying potential pathways involved in proteinuria and TMA and is investigating ways to address these complications.

Q. What are the infection risks associated with xenotransplantation, and why is lifelong monitoring important?

Dr. Tripathi: One concern is zoonosis, or the transmission of infection from an animal or animal organ to a human. Genetic modifications are intended to address this risk.

“There have been as many as 69 gene edits that have been done by eGenesis,” he said, referring to the company developing genetically engineered organs for transplantation.

Dr. Tripathi believes the risk of zoonotic infection is minimal, but this does not eliminate the risk of infection. Patients also face infections associated with immunosuppression, which is used to prevent their immune systems from rejecting a transplanted organ.

Dr. Tripathi’s group is also working toward accommodation and tolerance, which could allow transplanted organs to function with less immunosuppression.

He said lifelong monitoring of recipients will be needed to track outcomes and ensure continued medical care.

Q. India continues to face a significant organ shortage. How could xenotransplantation help bridge the gap between demand and supply?

Dr. Tripathi: India’s annual organ shortage is around 90,000, and it is increasing. The challenge is not just finding donors but ensuring they are medically fit and compatible with recipients.

He recalled a case in which an 85-year-old father-in-law was willing to donate a kidney to his daughter-in-law, but his age made him unsuitable, and no other family member was a match.

“The question is not whether you have a donor available. It’s also whether your donor is healthy or not,” he said.

He also raised ethical concerns about dependence on deceased-donor organs, arguing that patients should have alternatives that do not depend on another person’s death.

“I think xenotransplantation is not just going to solve a medical problem. It’s going to solve a moral problem,” he said.

Q. What is Sir Ganga Ram Hospital doing to advance xenotransplantation in India?

Dr. Tripathi: The aim is to carry out the first procedure with scientific support and within the necessary legal and ethical framework.

The team is prepared to move forward once the required guidelines are established and government permission is granted.

Q. How soon could India perform its first xenotransplant, and which type of transplant might reach clinical practice first?

Dr. Tripathi: I believe pancreatic islet-cell xenotransplantation could reach clinical practice before whole-organ transplantation.

Islet cells in the pancreas produce insulin, making them a potential area of research for conditions such as type 1 diabetes.

“It’s my scientific belief that islet-cell xenotransplantation would be the first one to hit the clinics,” he said.

As for India’s first xenotransplant, the timeline depends on government approval. “Potentially, six months from the day of the permission, we can perform the first transplant,” he said.

Q. What scientific, regulatory and biosecurity hurdles must India overcome before its first xenotransplant, and what lessons does the 1997 pig-organ transplant case involving Dr. Dhaniram Baruah in Assam offer today?

Dr. Tripathi: India’s first xenotransplant will have scientific, legal and ethical backing, along with patient consent. He said there was no comparison with the 1997 case involving Dr. Dhaniram Baruah in Assam, in which the patient died seven days after the procedure following multiple infections.

“We will not take a single step out of the legal ambit or the ethical ambit,” he said.

Q. Looking ahead five years, could India become a global leader in xenotransplantation?

Dr. Tripathi: India could play a leading international role. “India will be one of the leaders,” he said.

India can also establish its own xenorgan facilities over the next five to eight years. Until then, transporting organs from overseas companies could be an option, provided a secure transportation system is established in coordination with government authorities.
