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.

Summer vacations are ongoing, and at a time when heatwaves are at its worse, it is no wonder that most children and teens would prefer staying indoors. And for those who spend hours on video games, a psychologist has answered FAQs for parents. If you are concerned about the possibility of gaming addiction in your children, a senior psychologist lists symptoms and simple techniques to help parents deal with it better.

Neha Cadabams, Senior Psychologist and Executive Director at Cadabams Hospitals, in an interview with Health and Me, answered FAQs about the consequences of gaming addiction in children.

Parents often struggle to differentiate between normal gaming enthusiasm and problematic gaming behaviour. What are some of the earliest psychological warning signs that gaming may be becoming an unhealthy emotional dependency rather than just a hobby?

The difference usually becomes visible not through the number of hours spent gaming, but through the emotional role gaming begins to play in the child’s life. Gaming starts becoming concerning when it shifts from being recreational to becoming the primary way a child regulates emotions, avoids distress, or experiences self-worth.

Some of the earliest warning signs are emotional withdrawal from offline life, irritability or emotional outbursts when unable to game, noticeable sleep disruption, declining interest in activities they previously enjoyed, and increasing dependence on in-game achievements for confidence or validation. Parents may also notice that the child appears emotionally disengaged outside gaming environments or struggles to tolerate boredom, stress, or disappointment without returning to gaming immediately.

What is important to understand is that many children using gaming as an emotional coping mechanism continue functioning normally in school or daily routines initially, which is why the issue is often recognised late.

You mentioned that gaming often becomes an “escape hatch” for painful emotions. What are some of the deeper emotional or psychological struggles children may be trying to escape from through excessive gaming?

In many cases, excessive gaming is less about the game itself and more about what the virtual environment provides psychologically. For some children, gaming offers predictability, achievement, social acceptance, control, or emotional relief that they may not be experiencing consistently in real life.

The underlying emotional struggles can vary significantly. We commonly see children using gaming to cope with loneliness, social anxiety, bullying, academic pressure, low self-esteem, family conflict, emotional neglect, or feelings of inadequacy. For some adolescents, gaming becomes a space where they feel competent, valued, or emotionally safer than they do offline.

What makes this particularly concerning is that the emotional distress itself often remains hidden because the gaming behaviour becomes the visible focus. Families may attempt to reduce screen time without recognising the deeper emotional need the child is trying to fulfil through gaming.

Many teenagers who are struggling emotionally continue to perform normally in academics and daily life. Why is emotional distress among adolescents becoming harder for families to recognise today?

One of the biggest shifts we are seeing today is that emotional distress in adolescents no longer always appears as an obvious emotional breakdown or visible dysfunction. Many young people have become highly functional externally while internally struggling with anxiety, loneliness, emotional exhaustion, or low self-worth.

Adolescents today are also under constant pressure to remain socially connected, emotionally composed, and academically competitive. As a result, many learn to internalise distress rather than express it openly. Parents often expect mental health concerns to appear dramatically, but in reality, the early signs are usually subtle behavioural shifts such as emotional withdrawal, irritability, sleep changes, reduced communication, loss of interest in offline activities, or increasing emotional dependence on digital spaces.

Gaming can sometimes become one of the places where this hidden emotional life quietly reveals itself.

What are some common misconceptions parents have about gaming addiction and mental health?

One of the most common misconceptions is that gaming addiction is simply a discipline problem or a result of poor parenting. In reality, problematic gaming behaviour is often deeply connected to emotional coping, psychological vulnerability, and unmet emotional needs.

Another misconception is that all heavy gaming automatically indicates addiction. Many children and young adults engage deeply with gaming recreationally without it interfering with their emotional health or daily functioning. The concern begins when gaming starts replacing emotional coping, relationships, sleep, education, or the ability to function comfortably offline.

Parents also often focus only on restricting access to games without understanding why the child feels emotionally drawn toward gaming so strongly in the first place. Without addressing the underlying emotional factors, simply removing the game can sometimes intensify distress rather than resolve it.

With gaming becoming a massive part of youth culture in India, how can parents build healthier digital habits at home without making children feel controlled or misunderstood?

The starting point should not be surveillance or punishment, but emotional understanding and communication. Children are far more likely to engage positively with boundaries when they feel emotionally understood rather than judged.

Parents should focus on creating balance rather than framing gaming itself as the enemy. This includes encouraging offline activities, improving emotional conversations within the family, maintaining healthy sleep routines, and helping children build confidence and connection outside digital environments.

It is also important for parents to observe the emotional patterns around gaming rather than only the duration. How does the child behave when they are not gaming? Are they able to emotionally regulate offline? Are they socially connected outside virtual environments? Are they using gaming occasionally for enjoyment, or consistently to avoid discomfort, stress, or emotional pain?

In a country where diseases have become a daily topic of discussion, hypertension is gradually increasing behind closed doors. Also referred to as “the silent killer”, this ailment is notorious for making its presence known without symptoms, unlike many health conditions. By the time it is discovered, it may have already begun to affect vital organs.

Diabetes: A Comorbidity Giving Rise to This Vicious Cycle

One of the most prevalent comorbidities of hypertension is diabetes; together, the two create a difficult combination of chronic conditions affecting a patient's overall health. Diabetes causes high blood glucose (sugar) levels that, over time, damage blood vessels by reducing their ability to stretch or expand. When combined with the pressure caused by hypertension, these already compromised blood vessels can deteriorate rapidly, resulting in further damage.

The combined effects of diabetes and hypertension significantly increase the risk of heart-related complications, such as enlargement of the heart muscle, a reduced ability of the heart to pump blood effectively, and heart failure. Thus, the two conditions create a vicious cycle and emphasise the need for prompt diagnosis and treatment.

According to Dr Ameet Soni, AVP Medical Affairs, CORONA Remedies, “Hypertension and diabetes mellitus (DM) are two of the most common cardiometabolic disorders, often occurring together, and each exacerbates the impact of the other. When combined, these conditions significantly increase the risk of complications such as cardiovascular, cerebrovascular, and renal damage, particularly when symptoms are not identified early or when treatment adherence is inadequate. Minimising the risk of these complications depends on early identification, proactive risk assessment before diagnosis, and long-term adherence to treatment regimens for controlling blood glucose levels and blood pressure.”

According to Dr Manoj Chawla, Diabetologist, P.D. Hinduja Hospital and MRC, Khar, Mumbai, “These diseases are also termed ‘silent partners’, indicative of both their association and the silent damage they cause to bodily functions. The connection between these diseases in India is quite common owing to several factors, including a sedentary lifestyle, poor nutrition, obesity, excessive stress, and a lack of proper diagnosis. Individuals suffering from diabetes have twice the risk of developing hypertension compared with healthy individuals. Since both diseases are asymptomatic in many cases, patients may only discover them when complications arise. Early diagnosis of hypertension and diabetes is therefore vital. Tests such as blood pressure and blood glucose monitoring, weight management, proper nutrition, exercise, adequate sleep, and stress management all help to prevent these risks.”

Here are five alarming signs that your hypertension might be linked to diabetes.

1. Frequent Urination and Thirst: One of the earliest signs that hypertension may be associated with diabetes is frequent urination, accompanied by an abnormal increase in thirst. When blood sugar levels are high, the kidneys work overtime to filter and absorb excess sugar, leading to increased urine production. This, in turn, causes dehydration, prompting an increased thirst response.
2. Fatigue and Weakness: If you are experiencing unexplained fatigue or weakness, this could be a sign that your hypertension is coupled with diabetes. High blood sugar levels prevent glucose from entering the cells efficiently, leaving the body depleted of energy. Hypertension, in turn, places additional strain on the heart and circulatory system, leading to a further decline in overall energy levels.
3. Blurred Vision: The eyes are particularly vulnerable to the effects of both high blood pressure and diabetes. High blood sugar levels can damage the blood vessels in the retina, leading to diabetic retinopathy, which can cause blurred vision. Additionally, hypertension can further exacerbate this damage by increasing pressure within the blood vessels, resulting in worsening vision problems.
4. Numbness or Tingling in the Extremities: Diabetic neuropathy, a common complication of diabetes, causes nerve damage, particularly in the hands, feet, and legs. This nerve damage can lead to symptoms such as numbness, tingling or even a burning sensation in the extremities. When hypertension is present alongside diabetes, the blood vessels supplying the nerves may become compromised, exacerbating the symptoms of neuropathy.
5. Elevated Blood Sugar with Uncontrolled Hypertension: If your blood pressure is consistently high despite treatment or lifestyle changes, it could indicate an underlying issue, such as uncontrolled diabetes. Insulin resistance, which is common in type 2 diabetes, can worsen hypertension by increasing blood pressure due to factors such as weight gain and metabolic imbalances. When blood sugar levels are poorly managed, they can interfere with blood pressure regulation.

Early detection and intervention are key to managing both conditions and reducing the risk of complications. If you are experiencing any of the symptoms mentioned above or have a family history of either condition, it is vital to consult your healthcare provider. Regular screenings, lifestyle modifications and adherence to prescribed treatments can help control both hypertension and diabetes, improving your quality of life and preventing long-term complications.

Parkinson’s disease is characterized by slowness of daily activities, rigidity, and tremors with gait issues, commonly seen after the age of 45-50 years.

It is two times more common in men than women, though clinical features, response to the treatment, and prognosis are different in women as compared to men. From subtle early signs to how the condition develops over time, gender can shape the Parkinson’s journey in important ways.

Women usually experience Parkinson’s disease at a later age, but with faster progression of symptoms as compared to men. There is a need for more research in this space; however, we will try to shed light on these differences in Parkinson's trajectories in men and women based on available evidence.

Why Is Parkinson’s Less Common In Women?

Estrogen, a group of primary female sex hormones, is neuroprotective and protects dopaminergic neurons in women; women also have a higher baseline reserve of dopaminergic neurons. Hence, Parkinsonism is less common in women.

In the post-menopausal period, once this estrogen-related neuroprotective effect disappears, Parkinson’s symptoms progress rapidly. Motor symptoms emerge later in women with tremors, rigidity, and gait disturbances being more common and severe. Freezing of gait and postural instability with falls are more common in women.

Differences In Motor vs Non-Motor Symptoms

Non-motor symptoms like pain, fatigue, autonomic disturbances, sleep disorders, constipation, and mood disorders, including depression and anxiety, are more common and severe in women. Men with Parkinson’s disease have worse general cognitive abilities; however, women have worse visuospatial abilities.

Women with Parkinson’s receive less social support, lower quality care, attend medical appointments alone, and report more psychological stress. Women have a lower body mass index and higher bioavailability of levodopa, which makes them more susceptible to the side effects of levodopa, such as motor fluctuations and dyskinesia, which entail involuntary movements like fidgeting and writhing.

Why Personalized Treatment Matters

There is a clear need for personalized and tailored treatment. The different and distinctive clinical features in women, like later onset, higher tremors and rigidity, higher dyskinesia and motor fluctuations from drugs, and worse non-motor symptoms, require tailored, sex-specific treatment strategies rather than a “one-size-fits-all” approach.

Clinicians must give importance to the screening and management of non-motor symptoms in women, which are the main factors of their decreased quality of life. Women with this ailment go through longer delays in diagnosis and less access to specialists, highlighting a need for better healthcare access for women.
