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.

As men step into their 50s and beyond, prostate health becomes an essential part of overall wellbeing. The gland naturally undergoes changes with age, many of which are not cancerous but can still cause discomfort, disrupt daily routines, and affect long-term health. Awareness, early screening, and preventive habits play a crucial role in staying ahead of potential problems.
One of the most common age-related concerns is benign prostate hyperplasia (BPH), a non-cancerous enlargement of the prostate. This happens due to hormonal shifts that cause the gland to grow slowly over time.
“Most men assume urinary symptoms are just a normal part of aging, but that mindset often delays treatment,” says Dr. Vineet Malhotra, Director and Founder, VNA Hospital. “BPH itself is not dangerous, but if ignored, it can seriously affect quality of life and even lead to complications.”
These symptoms often creep up gradually, making them easy to dismiss until they start interfering with sleep, work, or general comfort.
While BPH is not cancer, men must remain vigilant about prostate cancer, especially because its risk rises with age.
“Prostate cancer in early stages is usually silent,” explains Dr. Malhotra. “That is exactly why screening becomes so important once men cross 50.”
These tests help detect abnormalities long before symptoms appear. Early detection not only improves treatment outcomes but also prevents unnecessary anxiety or uncertainty.
Men should also stay alert for red-flag symptoms, including persistent pelvic pain, unexplained weight loss, blood in urine or semen, and sudden urinary changes.
Beyond medical screening, everyday habits have a strong influence on prostate wellbeing.
“A balanced diet, regular exercise, and maintaining a healthy weight can significantly reduce inflammation and support better prostate function.”
These choices not only support the prostate but also improve urinary health and hormonal balance.
Since stress can worsen urinary symptoms, incorporating yoga, meditation, or deep-breathing practices also makes a noticeable difference.
One of the biggest challenges is the reluctance many men feel when discussing urinary or sexual symptoms.
“Men often suffer quietly because these issues feel too personal,” says Dr. Malhotra. “But silence delays diagnosis and treatment. Open conversations can literally save lives.”
Families, caregivers, and partners can play a supportive role by encouraging early checkups and normalizing discussions around prostate health.
With rising life expectancy and a more active older population, prioritizing prostate health is no longer optional—it’s essential.
Early diagnosis, informed decision-making, and evidence-backed treatments give men the chance to maintain independence, comfort, and quality of life well into their later years.
As Dr. Malhotra puts it, “Prostate health is not just a medical concern—it’s a foundation for staying energetic, confident, and healthy as you age.”

Crossing 40 often brings subtle but noticeable changes in how your body feels and functions. Many people brush off early signs like morning stiffness, reduced flexibility, or frequent bathroom visits, not realizing these are part of natural age-related changes. These shifts primarily affect the bones, joints, and urinary system, areas that quietly define everyday comfort.
According to Dr. Aashish Chaudhry, Managing Director & Head, Orthopedics & Joint Replacement, Aakash Healthcare, these changes are expected but shouldn’t be ignored. “After 40, the body’s regenerative capacity slows down, particularly in bones and joints. Being aware of these changes helps in early prevention and better long-term outcomes,” he says.
Bone density gradually declines with age due to hormonal changes. Women experience a drop in estrogen, and men see reduced testosterone levels—both crucial for supporting bone formation.
“Lower hormone levels weaken the natural bone-building cycle,” explains Dr. Chaudhry. “This increases the risk of fractures and even slows down healing when injuries occur.”
To counter this, weight-bearing exercises and strength training are crucial. A diet rich in calcium, vitamin D, and protein supports bone metabolism and maintains strength.
Years of repetitive movements, combined with declining collagen production, make joints more vulnerable. Cartilage becomes less elastic, leading to stiffness, reduced mobility, and the early onset of osteoarthritis.
“Many people notice joint pain but assume it's just fatigue,” says Dr. Chaudhry. “In reality, early joint wear can be detected and managed much earlier with the right interventions.”
Flexibility-focused exercises like yoga or stretching, along with anti-inflammatory foods such as leafy greens, berries, nuts, and omega-3 sources, can ease stiffness and protect long-term mobility.
While both men and women experience changes in urinary patterns, men often notice symptoms more prominently due to prostate enlargement. A bigger prostate narrows the urinary passage, causing:
Women, on the other hand, may struggle with pelvic floor weakness, leading to leakage or urgency.
Dr. Chaudhry notes, “These symptoms are common after 40, but they shouldn’t be normalized. Early evaluation can prevent chronic discomfort.”
Hydration remains essential. Cutting back on caffeine, alcohol, and salty foods can also lighten urinary symptoms and prevent kidney irritation.
Shifting from reactive to preventive care is key after 40. The goal isn’t to stop ageing—it's to age comfortably and confidently.
“Think of this stage as preparing your body for the next decades,” says Dr. Chaudhry. “With the right lifestyle adjustments, most people can maintain excellent mobility and function well into older age.”

After the Thanksgiving, on Friday, the Food and Drug Administration (FDA)'s top vaccine regulator, Vinay Prasad made a clam that shocked the public-health established. "For the first time, the US FDA will acknowledge that COVID-19 vaccines have killed American children," he wrote in a leaked email to his staff, as reported by The Atlantic and The Washington Post.

The agency has identified that at least 10 children died after getting COVID shots.
The email has been perceived by physicians as a "threat". A response from 12 former FDA commissioners, published in The New England Journal of Medicine on Wednesday, called Prasad's memo "a threat to evidence-based vaccine policy and public health security". All of the potential vaccine related deaths reported to government were already reviewed by the agency's staff, and had reached "different conclusions", wrote the former commissioners.
Elsewhere, doctors and scientists have declared that there are no evidence that links COVID-19 vaccines to deaths in children. The commissioners have claimed that in an attempt to deliberately bring evidence, Prasad and his colleagues had engaged in an "evidence-manufacturing mission", a "dumpster dive" for shoddy data, or worse, a campaign of lying.
Prasad is one of several public health officials who, under Robert F. Kennedy Jr.’s leadership, have been steadily chipping away at public trust in vaccines. So far, he has not provided evidence to back his claims, and his estimate of vaccine-related deaths may be exaggerated. The memo’s intense language and focus on political complaints also cast doubt on his assertions.
However, something that cannot be ignored is that fact that his memo may have provoked people to deny even the possibility of COVID-vaccine-related deaths. The Atlantic notes that "the idea that mRNA-based shots have, tragically, killed a very small number of children is not far-fetched." The article written by Benjamin Mazer, a physician who specializes in pathology and laboratory, notes that the this does not imply a "catastrophic threat to public health" as tens of millions of doses of the same vaccines have saved young people.
Public-health experts agree that COVID vaccines, like all medical treatments, can cause side effects. Myocarditis, a rare heart inflammation seen mostly in adolescent boys and young men after mRNA shots, remains the most discussed risk. Although usually mild and far less severe than virus-induced myocarditis, a few deaths have been documented worldwide, including isolated cases in the U.S., South Korea, and two American teenagers described in a peer-reviewed report.
These findings fuel ongoing debate about whether extremely rare vaccine-related deaths are being overlooked. Some scientists, including Paul Offit and Michael Osterholm, say the evidence does not prove the vaccines caused these deaths, noting that population-level studies show no rise in mortality after vaccination. Others argue that well-investigated autopsy-confirmed cases should be taken seriously rather than dismissed outright.
Experts such as Krutika Kuppalli, as cited by Mazer, emphasize that even if deaths occur, they are so uncommon they do not appear statistically, while the benefits, significantly reduced COVID mortality, are unmistakable. However, individual cases still raise questions on health authorities and the stricter standards of proofs they have applied when vaccines were involved to create a room for skepticism.
The concern is that rare side effects of vaccines could go undiscovered and not that vaccinations are inherently harmful.
