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.

Men often carry the responsibility for their families. They work hard and manage professional pressures to provide the best for their loved ones. Yet, many men tend to neglect their own health, the one thing that makes everything else possible.

Across age groups, men often seek medical attention only when the problem becomes severe or when symptoms become impossible to ignore. The most unfortunate thing regarding health is that many health conditions develop silently for years before showing signs. Taking care of yourselves is not selfish; it is essential. After all, the healthier you are, the better equipped you are to support your family, pursue your goals, and enjoy a fulfilling life for years to come.

Prioritize Preventive Health Checkups

One of the best ways to keep an eye on your health is by scheduling regular health screenings. Many conditions, including High BP, Diabetes, high cholesterol, liver disease, and kidney disorders, may not cause noticeable symptoms in the early stages. Annual health checkups can help identify potential problems way before they become serious.

Depending on age and family history, men should also discuss appropriate cancer screenings. Early detection leads to simpler treatment and better outcomes. Make preventive health checkups a routine. Just as a vehicle performs better with regular servicing, your body also needs regular monitoring.

Muscle Mass Is The Key

Maintaining muscle mass is equally important for men as they age. Muscle plays a vital role in supporting metabolism. Even though it is important for improving insulin sensitivity, protecting bone health, and maintaining strength. You don’t need rigorous exercise daily.

Strength training two to four days a week is sufficient. It may also help support healthy testosterone levels and reduce the risk of chronic conditions like type 2 diabetes and heart disease. The best thing is that strength training doesn’t require spending hours in a gym. Consistency matters far more than perfection.

Sound Mind For A Sound Body

We often say that ‘sound mind in a sound body’. This is even true vice versa. Many men feel pressure to appear strong all the time, which can make things difficult. Stress, anxiety, and depression can affect anyone. Persistent fatigue, irritability, difficulty concentrating, or disrupted sleep may be warning signs.

Keep an eye on such changes. Discussion is not a sign of weakness. Talk to trusted family members, friends, or mental health professionals. It can make a significant difference.

Sleep Is The Real Game-Changer

Quality sleep is one of the most powerful tools for maintaining good health. Generally, adults need between seven and nine hours of sleep each night. It helps the body to repair tissues, regulates hormones, and supports brain function.

Poor sleep is linked to weight gain, increased stress, and weakened immune function. If your morning is often tiring or you are struggling with insomnia, then discuss it with your healthcare professional. Limit screen time before bed and avoid excessive caffeine late in the day. It can help improve sleep quality.

Take Heart Health Seriously

Heart disease remains one of the leading health risks for men worldwide. The good news is that many cardiovascular risk factors are largely preventable. A healthy weight, physical activity, and a balanced diet can significantly improve heart health.

Avoiding tobacco products and limiting alcohol consumption is also helpful. Add vegetables, fruits, lean proteins, whole grains, and healthy fats to your daily diet. Such a diet can support both heart and overall well-being. Daily brisk walk can help improve BP, cholesterol levels, and cardiovascular fitness.

Fever is one of the body's most common warning signals. In most cases, particularly among children, it is caused by a simple infection and resolves within a few days. However, when fever keeps returning repeatedly, follows a pattern, or occurs alongside other concerning symptoms, it may signal an underlying health condition that requires medical attention.

What Is A Recurring Fever?

Dr. Hemalata Arora, Director of Internal Medicine at Nanavati Max Super Speciality Hospital, Mumbai, told HealthandMe that a recurring fever refers to repeated episodes of elevated body temperature that are separated by days, weeks, or even months during which a person feels completely well.

While recurrent fevers can sometimes result from common viral infections, especially in children exposed to school environments, daycare settings, or seasonal illnesses, persistent or unexplained episodes warrant further investigation.

The expert stated that understanding the pattern of fever is often one of the most important clues in determining the cause.

What Can Cause Recurring Fever?

Dr. Diksha Goyal, Consultant in Internal Medicine at Marengo Asia Hospitals, Gurugram, told HealthandMe that a recurrent fever can occur when body temperature rises to 38°C or higher and reappears after improving or occurs intermittently over time.

Several medical conditions may cause recurring fever, including:

1. Chronic Infections such as tuberculosis (TB), urinary tract infections

2. Autoimmune Diseases

3. Immune System Disorders

4. Cancers, particularly blood-related cancers

5. Certain Viral Infections

Warning Signs That Should Not Be Ignored

While recurrent fever is not always dangerous, the experts emphasize that certain accompanying symptoms require prompt medical evaluation.

Dr. Arora notes that urgent attention is needed if recurring fever is associated with:

• Unexplained weight loss
• Night sweats
• Persistent fatigue or unusual tiredness
• Poor appetite
• Repeated vomiting
• Breathing difficulties
• Persistent abdominal pain
• Confusion or altered mental status

Dr. Goyal added that persistent cough, swollen lymph nodes, and unexplained body pain can also indicate an underlying condition requiring medical treatment.

These symptoms may point toward serious infections, immune system disorders, blood-related diseases, cancers, or inflammatory conditions in which the body's defense system triggers repeated inflammation without a clear infection.

Early Treatment For Better Outcomes

Another important warning sign is a fever that continues to recur despite treatment. According to Dr. Arora, repeated courses of antibiotics without a confirmed diagnosis should raise concern. In some cases, medications themselves can trigger fever, making a detailed medication history an important part of the evaluation.

The goal is not to panic but to seek timely medical assessment. Check for swollen lymph nodes, rashes, signs of infection, or evidence of systemic inflammation.

The experts noted that early medical evaluation can help identify the underlying cause, prevent complications, and ensure appropriate treatment. With timely diagnosis and proper management, many causes of recurrent fever can be effectively treated, allowing individuals to maintain their health and daily activities.

Tobacco use remains a global epidemic and one of the leading preventable causes of death worldwide. Despite a strong desire among many users to quit, relapse rates remain alarmingly high. A new study by researchers at the All India Institute of Medical Sciences (AIIMS), New Delhi, suggests that yoga could be a valuable tool in helping people quit tobacco.

Yoga Shows Promise for Tobacco Cessation

To evaluate the effectiveness of yoga in tobacco cessation, researchers led by Dr Gautam Sharma, Department of Cardiology and Centre for Integrative Medicine and Research, AIIMS, conducted a meta-analysis of five randomized controlled trials (RCTs) published up to September 2024.

The review included adults aged 18 years and older who used any form of tobacco, excluding vaping products. Participants were randomly assigned to yoga either as a standalone intervention or alongside conventional cessation treatments.

The primary outcome assessed was the 7-day point prevalence abstinence (7PPA), a standard measure of smoking cessation. Secondary outcomes included quality of life, depression, anxiety, and mood states.

The findings suggest that “yoga may serve as a moderately effective intervention for tobacco cessation, with an estimated effectiveness of around 50 per cent”, the team said in the paper.

How Yoga May Help People Quit Tobacco

Researchers found that active yoga styles such as Hatha, Vinyasa, and Iyengar yoga improved abstinence rates by helping reduce stress, depression, and negative emotions often associated with tobacco withdrawal.

Pranayama, or yogic breathing exercises, was found to reduce cravings and negative affect, making it easier for participants to cope with withdrawal symptoms.

The review also highlighted the importance of addressing psychological factors linked to tobacco addiction, including perceived stress, anxiety, depression, and emotional distress—all of which are known contributors to relapse.

While some studies reported stronger psychological benefits than others, overall evidence suggests yoga may support emotional well-being during the quitting process.

Yoga and Tobacco Addiction

Researchers believe yoga may help manage tobacco addiction through several biological mechanisms.

Nicotine stimulates nicotinic cholinergic receptors in the brain, triggering the release of neurotransmitters that produce pleasurable and rewarding effects. During withdrawal, stress-related hormones increase, leading to anxiety, cravings, and emotional discomfort.

Yoga appears to counter these effects by shifting the body from a state of sympathetic nervous system dominance ("fight or flight") to parasympathetic dominance ("rest and digest").

This shift may reduce activity in the hypothalamic-pituitary-adrenal (HPA) axis, lower cortisol levels, and decrease stress hormone production, helping individuals better manage cravings and withdrawal symptoms.

The team also noted that controlled breathing techniques can significantly influence emotional regulation, with voluntary breath control accounting for substantial variations in emotional states such as anger, fear, and joy.

India alone has more than 270 million active tobacco users. Given the widespread use of smokeless tobacco in the region—and the limited effectiveness of standard cessation medications for these users—yoga could offer an accessible, culturally familiar, and low-cost complementary approach, the researchers stressed.

While the results are encouraging, researchers also cautioned that larger and more standardized studies are needed.
