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.
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.
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.
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
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.
A common myth is that painful IVF injections are administered multiple times a day. (Photo credit: AI generated)
Many couples who consult a fertility specialist are advised to undergo Assisted Reproductive Techniques, such as in vitro fertilisation (IVF). However, there are many myths linked to IVF regarding pain and injections. According to the experts, the procedure is more manageable and less painful than commonly believed. This article helps debunk myths surrounding IVF injections.
Dr. Sneha Sathe, Clinical Director & Fertility Specialist, Nova IVF Fertility, Chembur, Mumbai and Dr. Anuranjita Pallavi, Consultant- Fertility & IVF Specialist, Motherhood Fertility & IVF , Kharghar, Navi Mumbai collectively listed some of the most common myths associated with the stigma surrounding IVF – whether it is painful, complicated, or even worth the financial investment.
Currently, many are opting for IVF, a process where eggs are collected from a woman’s ovaries and fertilised with sperm in a laboratory. The embryo is then transferred into the uterus for conception. Couples may consider IVF for several reasons, such as blocked fallopian tubes, low sperm count, hormonal issues, age-related fertility decline, or unexplained infertility. For many, IVF becomes a go-to option, offering hope and a chance to start a family. However, despite its growing success, IVF is still surrounded by fear, especially when it comes to injections and pain. Social media, hearsay, and lack of awareness often make the process seem more difficult and can prevent couples from exploring it.
The IVF journey is different for each woman. IVF does involve medical procedures, but it is not as painful or overwhelming as people believe. One of the biggest concerns around IVF is the use of injections. These injections are given to stimulate the ovaries to produce multiple eggs. While the idea of daily injections can be intimidating, most are administered using very fine needles and are relatively painless. Patients may feel slight discomfort, similar to a small prick, but it is usually manageable and short-lived.
Understanding the facts and debunking common myths can help reduce anxiety and build confidence in couples.
Couples often hesitate to opt for IVF due to the fear of injections and the assumption that the process will be extremely painful or emotionally exhausting. However, with advancements in fertility care today, IVF has become far more patient-friendly, safe, and comfortable than most people imagine. One of the biggest myths is that IVF injections are administered painfully multiple times throughout the day. In reality, most injections are scheduled and simple to administer, and many couples are even taught how to take them comfortably at home.
Another important aspect people often overlook is that IVF treatment today is highly personalised.
While some women may experience temporary bloating, mild cramps, mood changes, or fatigue due to hormonal medications, these symptoms are usually manageable and closely monitored by the facility team. Most women can continue their daily routine during treatment without any major challenges. Equally important are support, counselling, and clear communication with the fertility team, which help reduce anxiety and build confidence. It is necessary to understand that IVF is a step-by-step guided process designed to give couples hope and a better chance at parenthood. Hence, make sure to consult an expert, clear all doubts, and initiate IVF treatment as soon as possible to achieve the dream of pregnancy.

Everyone knows that when cancer is detected early, cure rates are far superior, side effects are much less, and treatment expenses are also less.
Diagnosis of cancer depends upon carrying out various tests and then their analysis to reach a conclusion.
These tests are radiological, like Chest X-ray, CT scans, MRI, Mammography, etc., and in histopathology, analysis of tissue, be it a small biopsy, large specimen handling, or Frozen Section. AI is empowered with large data to suggest and analyze minute patterns that are difficult for a human mind to comprehend, supported by machine learning.
With the use of AI in the analysis of radiological data, it points out suspicious changes (data is fed into its memory), but they are not very clearly visible to the human eye. Hence, it alerts the radiologist to have a close look at that and enhances accuracy and reduces the chances. It is the radiologist who takes the final call because it has to be correlated with the patient’s clinical findings and other information from other investigations of the patient.
Early detection of breast cancer has received a big boost from the integration of AI in the analysis of mammography data. Similar applications are also used by pathologists when they are examining the tissues because the final diagnosis of cancer can be obtained on histopathology only.
Use of AI is not without challenges: knowledge of proper tools and applications is critical. Results can not be relied upon blindly, and an expert is very critical of their analysis. Sometimes there may be an improper result that needs to be filtered out.
It's time to accept that AI is present and not the future, and we need to learn, adapt, and use it to the benefit of mankind. India is making great strides in AI, and many startups have also come up that are doing a great job.
The real strength of AI in the care of cancer mainly lies in its ability to support the doctors in making faster, sharper, and more well-informed decisions. It can also reduce delay in diagnostics, improve efficiency of screening, and help in detecting cancers at a stage where outcomes of treatment are much better.

Amid rising summer temperatures, along with pollution, eye specialists today warned that the heat and dust can add stress on the eyes, leading to dryness, allergies, infections, and irritation.
Delhi witnessed its first official heatwave day of the month on Tuesday, as scorching sunshine and dry winds pushed temperatures beyond 45°C across several parts of the city.
The India Meteorological Department (IMD) warned that conditions are likely to worsen over the coming days, with temperatures expected to rise to nearly 46°C on May 20.
The weather department has also issued an orange alert for Delhi until May 25, cautioning residents about prolonged heatwaves and excessive heat conditions expected over six consecutive days.
Speaking to HealthandMe, Dr. Bhavatharini M, Senior Consultant Ophthalmologist at Dr. Agarwal's Eye Hospital, said that summer conditions can significantly impact eye health.
“Summer places added stress on the eyes, particularly in cities like New Delhi where heat, dust, and pollution are significant factors,” she said.
Dr. Bhavatharini explained that common concerns during the season include dryness caused by increased tear evaporation while
Dr. Kalpana R, Senior Consultant, Ophthalmology at SIMS Hospital, also warned of problems that affect the eyes during this season, such as
She stressed the importance of maintaining proper hydration and following a balanced, nutritious diet to support eye health during the hotter months.
Dr. Bhavatharini advised people to take simple preventive measures, such as wearing UV-protective sunglasses, staying well-hydrated, avoiding rubbing their eyes, and using protective goggles while swimming.
“Persistent redness, irritation, or blurred vision should not be ignored and warrants timely evaluation by your eye specialist,” she added.
Dr. Kalpana further recommended wearing protective eyewear outdoors to shield the eyes from harmful UV rays and glare.
People travelling on bikes should wear helmets with visors to reduce exposure to dust and pollution, while swimmers should use swimming goggles to prevent infections and injuries associated with pool water.
For allergies, she advised people not to rub their eyes even if they experience itching.
“Just as a home remedy, you can use an ice pack over the closed eyelids or splash cold water over the closed eyelids to get some immediate relief,” she told HealthandMe.
The experts also warned against self-medication in case of eye infections.
“And for viral infections and bacterial infections, if you feel that you get a sticky discharge and redness, you must immediately go to an ophthalmologist and get it treated. Never use over-the-counter medicines for any of your infections,” Dr. Kalpana said.
She added that people with common cold symptoms should wear masks and avoid touching commonly used surfaces if they have signs of an eye infection, as infections can spread through secretions.
