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.

A fall at home might look small, but for women older than 65, a broken hip can be a big and serious health problem. In real medical terms, this condition has a 20 to 30 percent chance of being deadly within the first year.

As people get older, their bones get weaker because of osteoporosis, which makes them more likely to break even from small falls. However, the bigger problem starts once the injury happens.

According to World Health organization (WHO), around 60 per cent of people living with osteoarthritis are women, yet awareness remains limited until symptoms begin to interfere with mobility and daily function.

Loss Of Muscles

Reports show that 70 per cent of women will get arthritis and osteoporosis. Most of them had no idea it was coming. HealthandMe spoke to experts to understand the reasons behind the trend.

Dr Gurdeep Avinash Ratra, Consultant - Orthopedics and Joint Replacement, Manipal Hospitals, Gurugram said that the development of these disorders is gradual and closely tied to physiological changes.

“After the age of 30, there is a steady decline in muscle mass, accompanied by a more rapid reduction in strength and power. With menopause, the significant fall in estrogen levels removes natural protection for bone density and joint health. Over time, this leads to increased bone fragility, reduced muscular support, and stress on joints, thereby elevating the risk of fractures and chronic joint conditions,” Ratra told HealthandMe.

Health Coach Prashant Desai in a post on social media platform X, noted that after the age of 30:

• muscle mass starts declining by 1 per cent every year.
• muscle strength declines three times faster.
• muscle power declines eight times faster.

Treatment

Experts said a hip fracture needs to be treated right away as a serious medical problem that requires care from many different medical specialists, not just a doctor who focuses on bones.

Dr Rajesh Kumar Verma, Director – Orthopedics & Joint Replacement, Max Super Speciality Hospital, Vaishali explained that limited movement can cause blood clots, chest infections, pressure sores, and loss of muscle quickly. Many patients also face a quick drop in their ability to take care of themselves, which can impact both their body and mind.

“Delayed treatment further increases risk. Early surgery and prompt recovery treatment help increase the chances of surviving and recovering better,” Verma told HealthandMe.

How to Prevent

• Maintaining a healthy waist circumference as an early indicator of metabolic health.
• Engaging in regular strength training to preserve bone density and muscle mass.
• Ensuring adequate protein intake to support muscle maintenance.
• Incorporating sufficient calcium and Vitamin D into the diet.
• Remaining physically active, with exercise beyond low impact activities alone.
• Get medical help right away if you fall or think you might have a broken bone.
• Have surgery as soon as your doctor suggests it, because it can help you recover better.
• Begin physiotherapy as soon as possible after the surgery to help restore movement and avoid any serious issues.
• Make sure to eat well, paying special attention to getting enough protein, calcium, and vitamin D.
• Check for fall risks at home by looking at things like lighting, floor surfaces, and handrails.

What to avoid

• Do not wait to go to the hospital, even if the hip fracture pain feels okay.
• Avoid staying in bed for long because a hip fracture can lead to infections, pressure sores, and blood clots.
• Do not skip osteoporosis treatment for hip fractures because it is very important to stop broken bones from happening again.
• Avoid skipping follow-ups or rehabilitation sessions for hip fractures after the surgery.

World Health Day serves as a reminder that regular preventive health check-ups stand as mandatory health assessments that all women need to undergo for their long-term health.

Many serious conditions, such as breast cancer, cervical cancer, thyroid disorders, diabetes, and cardiovascular diseases, often remain silent in their early stages, making regular screening the most effective way to detect them early, when treatment is simpler, less invasive, and more successful.

How Preventive Healthcare Can Help Women

Preventive healthcare enables women to take a proactive role in managing their health rather than responding to illness at an advanced stage. Early detection not only improves clinical outcomes but also effectively decreases treatment difficulties, emotional distress and financial costs while providing superior long-term life quality.

This also helps in identifying risk factors early, allowing timely lifestyle modifications that can prevent disease onset altogether.

Despite this, women often deprioritize their own health due to the multiple roles they juggle, balancing careers, caregiving responsibilities, and family needs. There is also a continued hesitation around discussing reproductive and intimate health concerns, along with a lack of awareness, fear of diagnosis, and social stigma, all of which contribute to delays in seeking timely care.

In many cases, women assume that the absence of symptoms indicates good health, which is a common but risky misconception.

Importance Of Routine Screening

Routine screenings such as Pap smears for cervical health, regular breast examinations, mammography where indicated, thyroid function tests, and basic metabolic screenings like blood sugar and cholesterol levels are critical tools in preventive care.

Periodic health check-ups also provide an opportunity for counselling on nutrition, mental well-being, hormonal health, and lifestyle management, areas that are often overlooked but equally important.

World Health Day serves as a reminder to shift from a reactive to a preventive approach. Prioritizing regular health check-ups, normalizing conversations around women’s health, and encouraging a culture of self-care can significantly improve outcomes. Investing in preventive healthcare is one of the most powerful steps women can take towards leading healthier, longer, and more empowered lives.

The root of many health issues stems from the sleep pattern we imbibe in our daily lives. Beyond that, sleep can also act as a mirror to your mental and emotional state. When stress builds up, it rarely switches off at bedtime; instead, it shows up through vivid dreams, frequent night waking, or a sense of anxiety in the early hours of the morning. Dr. Shiva Kumar R, Head and Senior Consultant—Neurology, Manipal Hospital, Sarjapur Road, decoded the link between stress dreams and early morning anxiety.

What are stress dreams?

One of the most common signs is having stress dreams. These dreams are often very strong, repetitive, or emotionally charged, like being chased, not being ready for an exam, or losing control of a situation. Your brain uses them to work through thoughts and feelings that aren't fully formed. When you don't fully deal with your stress, your mind keeps working on it while you sleep.

Waking up at night is another sign you should pay attention to. If you wake up several times without a clear physical reason, it could be because you are more alert. Stress keeps your nervous system in a semi-active state, which makes it harder for your body to get the deep, restorative sleep it needs. Because of this, even small noises can wake you up.

Is there a solution?

Early morning anxiety, where you wake up with a sense of dread or racing thoughts, is also closely tied to stress. Cortisol, the body’s stress hormone, naturally rises in the early morning. However, when you’re overwhelmed, this spike can feel more intense, triggering anxious thoughts before your day even begins.

These patterns are more than just interruptions; they are signs. Your sleep needs attention, balance, and care. Keeping a regular sleep schedule, limiting screen time before bed, using relaxation techniques, or writing down your thoughts can all help lighten your mental load.

If these feelings don't go away, it might be a good idea to look into what is causing them or get help from a professional. The first step toward better mental and emotional health may be to pay attention to what your sleep is trying to tell you.
