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?

Blue light is part of the visible light spectrum and is emitted by natural and artificial sources like the sun, fluorescent lights, LED lights, and digital screens. This wavelength is known for influencing our alertness, mood, and sleep patterns. During the day, blue light plays a role in regulating circadian rhythms, helping us stay alert and focused. However, exposure to it in the evening can have a detrimental effect on sleep quality.

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.

Updated Jan 30, 2026 | 11:00 PM IST

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.

What Are Menopause Clinics?

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:

  • Clinical assessment of menopausal symptoms
  • Screening for hormonal and physical health issues, such as bone health and heart disease risk
  • Mental health support and psychosocial counselling
  • Personalized advice on lifestyle, nutrition and mid-life wellness
  • Ongoing patient education and structured follow-up

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.

What Is Menopause?

This is the natural, permanent end of menstruation defined as 12 consecutive months without a period. This typically occurs between ages 45 to 55.

Foods That May Help During Menopause

  • Soy: A top source of phytoestrogens, particularly isoflavones, which bind to estrogen receptors in your body. Studies suggest soy may help alleviate hot flashes, improve cholesterol levels, and even reduce the risk of heart disease during menopause.
  • Flaxseed: Packed with lignans, a type of phytoestrogen with mild estrogenic effects, flaxseed may also offer some relief.

Including these foods in your diet could help ease symptoms and reduce your risk of certain menopause-related conditions.

Why a Balanced Diet Matters

A nutrient-packed, balanced diet is the foundation of good health at any age. Prioritize:

  • Vegetables and fruits: Rich in vitamins and antioxidants.
  • Whole grains: Great for maintaining steady blood sugar levels.
  • Lean proteins: Support muscle health and repair.
  • Low-fat dairy: Provides calcium for bone strength.
  • Avoid ultra-processed junk foods, excessive sugar, and unhealthy fats, which contribute little beyond empty calories.

Maharashtra Menopause Clinic

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.

Kerala follows with dedicated clinics

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.

Bruce Willis’ Wife Emma Says He Is Unaware of His Dementia Diagnosis

Updated Jan 30, 2026 | 12:48 PM IST

SummaryBruce Willis’ wife Emma Heming Willis has shared that he is unaware of his frontotemporal dementia diagnosis. Recalling feeling lost and afraid, she described the shock of diagnosis, becoming his full-time caregiver, and her decision to write a book to support families facing similar journeys.

Bruce Willis was diagnosed with frontotemporal dementia in 2022. His wife, Emma Heming Willis recalled the day when Bruce was diagnosed with the condition and how it made her feel "lost, isolated and afraid." Talkin to PEOPLE, Emma said, Bruce "never connected the dots" that he has been diagnosed with frontotemporal dementia. “I think that's like the blessing and the curse of this, is that he never connected the dots that he had this disease, and I'm really happy about that. I'm really happy that he doesn't know about it,” she shared about Bruce, 70.

Bruce Willis' Diagnosis

"On the day Bruce got his diagnosis, we walked out of the doctor's office with a pamphlet and an empty goodbye. No plan, no guidance, no hope, just shock," she explained in front of a packed auditorium, People reported.

In one instant, the family's future disappeared. The Oscar-winning actor, famous for his quick wit and performances in Die Hard and The Sixth Sense, would be leaving his career behind. Emma found herself thrust into a whole new role of full-time caregiver at the same time.

She continued to explain, "I found myself having to keep my family intact, raise our two small girls, and tend to the man that I love while dealing with an illness I hardly knew anything about."

Emma's emotional candor resonated with hundreds of families who have received similar diagnoses and encouraged her to author a book, The Unexpected Journey, scheduled for publication in September. In Emma's words, "This is the book I hope will assist the next caregiver. It is packed with encouragement, wisdom, and the encouragement necessary to walk this path.

What Is Frontotemporal Dementia?

Frontotemporal dementia is a less prevalent type of dementia that mainly occurs in the frontal and temporal lobes of the brain. It tends to affect behavior, personality, language, and movement more than memory, particularly in its initial stages.

In contrast to Alzheimer's, which generally strikes older individuals, FTD can hit at an earlier age—sometimes as young as 40. The symptoms can range from changes in personality, emotional flatness, or the inability to show empathy to impulsiveness, so it is especially hard for spouses and children to cope.

Emma's case illustrates how abrupt and disrupting this diagnosis can be—not only for the patient but for caregivers as well.

Whereas Bruce Willis' diagnosis hit global headlines, the mental toll taken by Emma, his caregiver, was largely in the background—until she decided to come forward.

Caregiving is a respectable position, but it's also a challenging and thankless one. For those who are caring for loved ones with dementia or other chronic illnesses, the stress of "keeping it all together" can result in a condition called caregiver burnout.

"Caring for someone is the most intimate and demanding work of love," Emma explained, "but when you're not noticed or supported, it begins to undermine your health—mentally and physically."

‘Work Stress Makes You Gay’: Why Malaysian Minister's Remark Proves The Need To Understand Sex, Gender And Sexuality

Updated Jan 30, 2026 | 12:10 PM IST

SummaryMalaysian minister Zulkifli Hasan’s claim that work stress can make people gay sparked backlash and misinformation. Experts stress there is no scientific evidence linking stress to sexual orientation, highlighting the need to understand the clear differences between sex, gender and sexuality, which are distinct biological, social and psychological concepts.

Work stress could make you gay, said a Malaysian minister Zulkifli Hasan, as continued government intervention of what is described as 'sexually deviant behavior' has pressured the country's LGBTQ community. This happened two weeks after religious authorities and police acted on complaints from a sultan and Islamist politicians that a camping retreat was promoting the LGBTQ lifestyle, reported South China Morning Post.

Religious Affairs Minister Hasan on Tuesday said that work stress could be among many other factors that is pushing people into sexual orientations other than heterosexuality. “Societal influence, sexual experiences, work stress and other personal factors come under this category [of possible causes],” Zulkifli said in a written parliamentary reply to a question by Siti Zailah Mohd Yusoff, a lawmaker with the opposition Islamist party PAS.

He cited a 2017 study by Sulaiman et.al., that said such elements "can contribute to the increase in LGBT acts".

His comments have attracted a lot of backlash, with many people on social media mocking him. A social media user Muaz Zam said, "By this logic, I am genuinely shocked my entire office isn't gay by now". Another one read: "In other words: they never work hard in the parliament."

However, these claims are not scientifically back. Work related stress can impact a person, but cannot change their sexuality. It can, however, cause health effects. What it does not do is change one's sexuality and this is why one should know the difference about gender, sex and sexual orientation or sexuality.

'Work Stress Makes You Gay': The Difference Between Gender vs Sex

While these both terms are often used interchangeably in official forms, there is a difference between the two.

As per the Council of Europe, gender is an area that cuts across thinking about society, law, politics, and culture.

Definition Of Gender vs Sex by WHO

The World Health Organization notes that sex refers to: "the different biological and physiological characteristics of males and females, such as reproductive organs, chromosomes, hormones, etc.”

Whereas, gender refers to: "the socially constructed characteristics of women and men – such as norms, roles and relationships of and between groups of women and men. It varies from society to society and can be changed. The concept of gender includes five important elements: relational, hierarchical, historical, contextual and institutional. While most people are born either male or female, they are taught appropriate norms and behaviours – including how they should interact with others of the same or opposite sex within households, communities and work places. When individuals or groups do not “fit” established gender norms they often face stigma, discriminatory practices or social exclusion – all of which adversely affect health."

Definition Of Gender vs Sex by The European Institute For Gender Equality

Sex refers to the biological and physiological characteristics that define humans as female or male. These sets of biological characteristics are not mutually exclusive, as there are individuals who possess both, but these characteristics tend to differentiate humans as females or males.”

Gender refers to the social attributes and opportunities associated with being female and male and to the relationships between women and men and girls and boys, as well as to the relations between women and those between men. These attributes, opportunities and relationships are socially constructed and are learned through socialisation processes. They are context- and time-specific, and changeable. Gender determines what is expected, allowed and valued in a woman or a man in a given context. In most societies, there are differences and inequalities between women and men in responsibilities assigned, activities undertaken, access to and control over resources, as well as decision-making opportunities. Gender is part of the broader sociocultural context. Other important criteria for sociocultural analysis include class, race, poverty level, ethnic group and age.”

The main difference is that gender is a social construct, whereas sex is the biologically labelled term based on organs and hormones.

What Is Sexuality?

LGBTQ community (Canva)

As per the American Psychological Association (APA), sexuality is the capacity to derive pleasure from various forms of sexual activity and behavior. The Lanarkshire Sexual Health describes sexual orientation as a way to describe the feelings you have for someone you fancy or are attached to.

While sexuality can change overtime, it is not a choice. There is no evidence that sexual orientation can be forced to change through therapy.

Can Stress Impact Sexuality?

While stress can impact sexual function by reducing libido, causing fatigue, and triggering hormonal changes, it does not change one's sexual orientation. Jason Teoh, who writes on LGBTQ issues, project partner at NSW Department of Planning, Housing and Infrastructure, notes: "Sexual orientation is not caused by stress. It is not caused by trauma, influence or difficult life circumstances."

The WHO notes: sexual orientation is a natural, stable part of human identity shaped by biology, genetics, and early development. The WHO removed homosexuality from its disease classification in 1990. The American Psychiatric Association did the same in 1973.
