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.

Supreme Court on Friday declared the right to menstrual health as part of the right to life under Article 21 of the Constitution. The court issued a slew of directions to ensure that every school provides biodegradable sanitary napkins free of cost to adolescent girls. The guidelines also ensured that schools must be equipped with functional and hygienic gender-segregated toilets. The Court directed the pan-India implementation of the Union's national policy, 'Menstrual Hygiene Policy for School-going Girls' in schools for adolescent girl children from Classes 6-12.

A bench comprising Justice JB Pardiwala and Justice R Mahadevan passed the following directions:
The court also issued directions for the disposal of sanitary waste. Justice Pardiwala said, "This pronouncement is not just for stakeholders of the legal system. It is also meant for classrooms where girls hesitate to ask for help. It is for teachers who want to help but are restrained due to a lack of resources. And it is for parents who may not realise the impact of their silence and for society to establish its progress as a measure in how we protect the most vulnerable. We wish to communicate to every girlchild who may have become a victim of absenteeism because her body was perceived as a burden when the fault is not hers."

In India, menstruation is still seen as taboo. In fact, there is a lot of shame around it. Menstrual shame is the deeply internalized stigma, embarrassment, and negative perception surrounding menstruation, which causes individuals to feel unclean, or "less than" for a natural biological process. This judgment thus is an effort to do away with the shame rooted in cultural, social, and religious taboos, which is often the reason why many girls drop out, or due to lack of awareness, develop health adversities.

Most health videos on YouTube, even those made by doctors are also not reliable medical information, found a new study, published in JAMA Network Open. The researchers reviewed 309 popular YouTube videos on cancer and diabetes and found that fewer than 1 in 5 were supported by high quality scientific evidence. About two-thirds of the view had low, very low or no evidence at all to back up their health claims.
What was more concerning is that weaker evidence often attracted more viewer than those backed with strong science. The study looked at videos which had at least 10,000 views. The lead author of the study Dr EunKyo Kang of South Korea's National Cancer Center, said, "This reveals a substantial credibility-evidence gap in medical content videos, where physician authority frequently legitimizes claims lacking robust empirical support."
"Our findings underscore the necessity for evidence-based content-creation guidelines, enhanced science communication training for health care professionals, and algorithmic reforms prioritizing scientific rigor alongside engagement metrics," Kang added in a news release.
The researchers reviewed videos from June 20 and 21, 2025, focusing on cancer and diabetes content. 75 per cent of them were made by physicians. The videos had a median count of 164,000 views and a median length of 19 minutes.
Researchers also developed a scoring system, called E-GRADE to rate the strength of science backed evidence in each video's claim.
The study also found that videos with the weakest evidence were 35% more likely to get higher views than videos with strong scientific evidence.
Richard Saver, a professor of law at the University of North Carolina at Chapel Hill noted that this issue is not just limited to YouTube. "Physician-spread misinformation is a long-standing problem, dating back well before the internet era," he wrote in an accompanying editorial.
Saver said some doctors continue to lean on personal experience rather than solid data, despite evidence-based medicine being regarded as the gold standard. He noted that EBM can feel like it downplays individual clinical judgment. Still, Saver stressed that more research is needed, adding that the study underscores the importance of examining the evidence behind health professionals’ claims on social media.
Health and Me has always stayed a step ahead from medical misinformation and ensured that its readers too consume correct information. Health and Me's Fact Check series have consistently ran checks on bizarre medical claims, whether it is about a magical potion for weight loss, fake health news, or un-scientific remedies.

The World Health Organization (WHO) noted that menopause often goes unnoticed as a clinical priority, observing these unmet needs, the state governments in Maharashtra and Kerala will soon launch government-run menopause clinics. These clinics will have specialized support systems designed to offer holistic healthcare services for menopausal women within the public system.
These clinics will also have medical consultations, mental health counselling, targeted screening services and lifestyle guidance.
Menopause clinics are specialized healthcare units, usually housed in government hospitals, urban health centres or district hospitals, that focus on both the medical and emotional needs of women transitioning through menopause. Rather than brushing menopause aside as a “natural” phase that needs little attention, these clinics offer organized, evidence-based care that goes well beyond routine outpatient visits.
At the heart of a menopause clinic is a comprehensive, integrated approach that includes:
By bringing these services together under one roof, menopause clinics help women cope with day-to-day symptoms while also addressing long-term risks like osteoporosis, metabolic changes and a higher likelihood of cardiovascular disease.
This is the natural, permanent end of menstruation defined as 12 consecutive months without a period. This typically occurs between ages 45 to 55.
Including these foods in your diet could help ease symptoms and reduce your risk of certain menopause-related conditions.
A nutrient-packed, balanced diet is the foundation of good health at any age. Prioritize:
Earlier this January, the Maharashtra government rolled out the country’s first state-run menopause clinics across government hospitals and urban health facilities. The initiative was launched on Makar Sankranti, January 14, under the guidance of Minister of State for Health Meghna Bordikar.
As per official statements, these clinics are designed to offer end-to-end care in one place. Services include expert medical consultations to evaluate and manage menopausal symptoms, mental health support to address emotional and psychological concerns, and screenings for bone health, cardiovascular risk and hormonal balance. Medicines and follow-up advice are also provided during the same visit, cutting down the need for multiple referrals and repeat hospital trips.
A senior health official pointed out that while menopause is a natural life stage and not a disease, many women need consistent physical and emotional support during this transition. The strong response from women across Maharashtra highlights a long-standing gap in healthcare, where menopause-related concerns often went unaddressed due to the absence of dedicated services. With this move, Maharashtra has also set an example for other states looking to introduce gender-specific care within public health systems.

Taking a cue from Maharashtra, the Kerala government has announced plans to set up specialized menopause clinics in district hospitals. An initial allocation of Rs 3 crore has been earmarked for the project in the 2026 state budget, presented by Finance Minister K N Balagopal.
The proposed clinics in Kerala will follow a similar model, offering medical consultations for menopausal symptoms, mental health counselling, and screenings for heart, bone and hormonal health. Women will also receive medicines along with lifestyle and dietary advice at a single facility.
The initiative acknowledges the wide-ranging impact of menopause, including hormonal changes, sleep disturbances, bone health issues and increased stress, and aims to create a one-stop support system within district hospitals. By bringing menopause care into mainstream public healthcare, Kerala hopes to improve access, reduce stigma and ensure that women receive timely, structured support during this phase of life.
