Many people believe that the modern-day skincare trends are a scam made by the big pharma companies who wish to make more money. This is a recent trend of ‘Anti-Aging’ skincare that keeps yourself on toes for the innate need for women to stay ‘young’ if they wish to be desirable. The beauty industry, in a way, feeds on such societal-made insecurities. But the recent rise in the trend has taken a different turn. While before people did it before to look prettier or fairer, now people are looking at this skincare routine as a way of taking care of themselves rather than doing to match someone else's beauty standards. This is why, this trend has resurfaced in the skin care community. This is the blue light routine.

In today's digital age, where we spend countless hours looking at screens, from phones and tablets to laptops. This constant screen time exposes us to blue light, which research suggests can have negative effects on our skin. It also leads to premature aging and dark spots. The screens also leads to stress, which could further cause harm to skin. While ditching our devices isn't realistic, a growing number of skincare products claim to protect against blue light. But do these products actually work?

What is Blue Light Skincare?

You can find many skincare products that say they protect against blue light, like sprays, creams, gels, and sunscreens. Some promise to undo the damage blue light might cause, while others try to prevent it in the first place. Blue light sunscreens are special because they protect against both the sun's UV rays and blue light. This is what regular sunscreens don't do very well. Regular sunscreens, whether they use chemicals or minerals, don't block blue light as effectively.

However, tinted sunscreens are different. Tinted sunscreens with SPF 30 or higher can protect your skin from blue light, as well as UVA and UVB rays from the sun. This is because of the coloring in the tint. Some newer sunscreens also have special ingredients that help protect against visible light, including blue light. While scientists are still learning about how blue light affects skin, many skin doctors have found it to be helpful for skin.

What is Blue Light and Why Might It Be a Problem?

Blue light comes from screens, TVs, and even the sun. While we used to worry mostly about how it affects our eyes and sleep, now we're learning it might also affect our skin. Some studies show that too much blue light can damage skin cells and speed up aging, leading to wrinkles and uneven skin tone. It can also cause dark spots on the skin. This happens because blue light can cause something called "oxidative stress" in the skin, which is linked to aging. It leads to dead skin cells. Blue light goes deeper into the skin than the sun's UV rays and can make skin cells produce more pigment, causing dark spots. It's important to know that not all blue light is bad. There is a difference between the blue light that comes out of the screens and the blue light that is used from a certain blue light wavelength as a therapy. The latter is used by doctors to treat acne and some skin cancers.

Ramzan, the holiest month in Islam, marked by dawn-to-dusk fasting, poses health risks for people with diabetes. Health experts urge patients to consult their doctors before observing the fast.

Ramzan is a period of intense spiritual reflection, self-discipline, and devotion for Muslims worldwide. During the month-long fasting period, the believers refrain from eating and even drinking (including water), from dawn to sunset.

The faithful eat a modest meal (sehri) before the first light of dawn to provide energy for the day. The fast is broken at sunset, traditionally starting with dates and water, followed by a larger meal (iftar).

According to health experts, for individuals whose diabetes is well controlled, fasting may be possible with proper adjustments.

"Diabetes requires regular monitoring, balanced meals, and timely medication. When eating patterns change during Ramzan, blood glucose levels can fluctuate. That is why I strongly recommend consulting your doctor before you plan to fast,” Dr. Saptarshi Bhattacharya, Senior Consultant, Endocrinology, Indraprastha Apollo Hospitals, told HealthandMe.

The expert advised people not to skip sehri, and to include complex carbohydrates such as whole grains, along with protein like eggs, dal, or curd, and plenty of fluids to help maintain stable glucose levels throughout the day.

At iftar, avoid overeating. Start with light, balanced food and limit fried items, sweets, and sugary drinks, as these can cause a sudden spike in blood glucose, Dr. Bhattacharya said.

Type 2 Diabetes patients with good glycemic control, lifestyle management, or stable oral medications can fast safely.

However, those on multiple insulin doses, with complications, or with poor control are considered moderate to high risk, Dr. Kartik Thakkar, Consultant Medicine, Ruby Hall Clinic, told HealthandMe.

The health expert also noted that most Type 1 diabetes patients are considered high risk, especially those with brittle diabetes, frequent hypoglycemia (low blood sugar), or a history of diabetic ketoacidosis (DKA). Many are medically advised not to fast, particularly if glucose control is unstable.

Children and adolescents with type 1 diabetes are considered high risk and are usually advised against fasting due to the unpredictable nature of insulin requirements.

Who Should Avoid Fasting Altogether?

• People with a history of severe hypoglycemia in the last 3 months;
• Recurrent hypoglycemia;
• Advanced kidney disease;
• Elderly patients with frailty; and
• Pregnant women with diabetes

Dr. Thakkar said that such individuals fall into the very high-risk category and are medically exempt from fasting.

The expert also suggested clinical tests to determine whether a diabetic patient is fit to fast. These include:

• Glycemic control (HbA1c levels)
• Duration of diabetes (long-standing diabetes can increase complication risk)
• Presence of complications (neuropathy, nephropathy, cardiovascular disease)
• Kidney function and hydration status

What Warning Signs Should Prompt Breaking The Fast Immediately?

A diabetic patient must break the fast if:

• Blood glucose <70 mg/dL (3.9 mmol/L)
• Blood glucose >300 mg/dL (16.7 mmol/L)
• Severe dizziness or fainting
• Confusion or blurred vision
• Persistent vomiting
• Symptoms of dehydration (extreme thirst, very low urine output)
• Chest pain or breathlessness

A new study has shown that people who survived COVID-19 infections are more likely to develop obstructive sleep apnea (OSA) for years after the infection with the SARS-CoV-2 virus.

OSA is a common and serious sleep disorder that causes the throat muscles to relax and block the airway, resulting in fragmented, nonrestorative sleep, low blood oxygen, and loud snoring.

The February 2026 study, published on the preprint server medRxiv, found that people with both severe and non-severe COVID infections are at higher risk of developing sleep apnea and other sleep issues for 4.5 years.

"SARS-CoV-2 infection is independently associated with increased risk of new-onset OSA. These findings support targeted screening in post-COVID populations,” said Sagar Changela, Department of Radiology, Albert Einstein College of Medicine, in the paper.

What The Study Found

Although an infection with the SARS-CoV-2 virus has been associated with long-term respiratory and neurological conditions, its role in new-onset OSA remains unclear.

The retrospective study, which has not been peer-reviewed, involved 910,393 patients. The results showed that patients hospitalized due to COVID were 41 percent at risk of new onset of OSA.

One-third of people with mild COVID infection, who weren't hospitalized, also suffered from sleep issues.

The researchers also linked OSA to cardiovascular, metabolic, and cognitive morbidity. The team found that OSA increased the risk of heart failure and pulmonary hypertension among hospitalized COVID patients, compared to those with mild infections.

On the other hand, the non-hospitalized COVID patients were significantly more likely than controls to develop obesity.

Further analyses showed that the risk of new-onset OSA was higher in hospitalized COVID patients with asthma and those who were younger than 60 years. Notably, women were also found at greater risk than men, while vaccination status did not vary by risk.

According to the team of researchers, the major factors for OSA among COVID patients are low-grade systemic inflammation after a SARS-CoV-2 infection that reduces upper-airway neuromuscular control.

In addition, the higher levels of inflammatory cytokines often seen in long-COVID patients can also affect respiratory drive and upper-airway stability -- key factors for OSA.

What Is Sleep Apnea?

Sleep apnea is a serious sleep disorder where a person's airway can collapse completely or partially. It causes breathing lapses during sleep, and the body stops breathing many times while an individual is asleep. It also weakens throat muscles, leading to airway collapse during sleep. The decrease in oxygen saturation can also lead to death.

While OSA is the most common type of the sleep disorder, other types include central sleep apnea and complex sleep apnea.

Obesity is the major cause of this disorder, and loud snoring is the most common symptom. The person suffering from the condition feels tired, even after getting adequate sleep.

Treating sleep apnea is key to preventing long-term health complications such as cardiovascular disease, hypertension, diabetes, stroke, and increased mortality.

CPAP machines, oral appliances, and lifestyle modifications are common and effective treatment measures.

For decades, diabetes conversations have revolved around diet, weight and genetics. While these remain central, growing medical evidence shows two often ignored factors play a powerful biological role in blood sugar control: stress and sleep.

Dr Narendra BS, Lead Consultant in Endocrinology and Diabetology at Aster Whitefield, Bengaluru, recently wrote for NDTV explaining that these are not minor lifestyle irritants but metabolic triggers.

According to him, poor sleep and chronic stress “create a biological environment that puts us at risk for developing type 2 diabetes or make it harder to control blood sugar if we already have the condition.”

How Stress Raises Blood Sugar

When the body senses danger, it activates its major stress systems including the hypothalamic pituitary adrenal axis and the sympathetic nervous system. These release cortisol and adrenaline, hormones designed to help survival.

They rapidly increase blood glucose so the body has instant energy. This is useful during emergencies but harmful when stress becomes constant.

“Continuous stress from work pressure, caregiving or anxiety reduces the body’s insulin sensitivity,” Dr Narendra explains. Over time, cells stop responding properly to insulin and glucose levels rise.

Long term studies now link persistent stress patterns to insulin resistance and a higher risk of diabetes. In simple terms, even if diet remains unchanged, chronic emotional strain can gradually push the body toward metabolic disease.

The Hidden Damage From Poor Sleep

Sleep disturbance works just as strongly against blood sugar regulation.

Sleep restriction, irregular schedules and fragmented sleep impair glucose tolerance, sometimes within days. Research shows that even partial sleep loss raises fasting glucose and insulin levels. Over time, this increases HbA1c and diabetes risk.

“When you don’t get good sleep, your body is simply not as efficient at handling sugar,” he notes.

The problem worsens because stress and sleep feed each other. Stress disrupts sleep, sleep deprivation increases stress hormones, and both promote unhealthy habits such as late night snacking, skipping exercise and excess caffeine intake.

Doctors in India increasingly link this cycle to urban lifestyles and rising diabetes prevalence.

Encouragingly, The Damage Can Be Reversed

The positive takeaway is that these effects are modifiable. Improving sleep duration and reducing stress measurably improves insulin sensitivity.

Sleep extension trials have shown improvements in glucose metabolism. Stress management programs have lowered fasting glucose and HbA1c levels.

Because the science is clear, Dr Narendra recommends that diabetes care must include mental and sleep assessment. Screening for insomnia, anxiety and depression should be routine in metabolic clinics.

What Patients Can Do

Sleep should be treated like medicine. Adults should aim for 7 to 8 hours of consistent sleep, maintain fixed bedtimes and avoid screens for at least an hour before bed. Shift workers may require specialist guidance due to circadian rhythm disruption.

Stress management can begin with simple practices. Deep breathing, mindfulness and short cognitive exercises can lower daily cortisol levels. Therapy and medication may help when anxiety or depression is present.

Physical activity is equally important. Regular exercise improves insulin response and prevents excessive stress reactions. Even a short walk after meals helps reduce blood sugar spikes.

A New Approach To Diabetes Care

Healthcare providers are encouraged to actively discuss sleep and psychological health during treatment. A combined approach using lifestyle modification, mental health care and medication provides better results than focusing on diet alone.

“Blood sugar is not just a number on a test,” Dr Narendra emphasizes. “It reflects lifestyle, biology and psychology. Addressing sleep and stress tackles a major but often neglected contributor to poor control.”

In short, managing diabetes is no longer only about what is on the plate. It is also about what happens at night and what weighs on the mind.
