Diwali is the time of the year when our nation’s children are on holiday and festivities are rampant. Sadly this fun time for children is also when firecrackers and fireworks are available in plenty. The word “firecrackers” evokes quite a bit of emotion and is often associated with great joy but one must realize that the chemical smoke and gases released from firecrackers can be regarded as a serious concern for the capacity of eyes for children.

It is shocking to know that mothers and fathers have been using firecrackers for this long despite it being scientifically proven to be a pollutant and one that can heavily damage children’s eyesight.

But now, as a parent, most people see things differently—firecracker smoke, while dazzling, risks young eyes and health. From choosing eco-friendly lights and indoor activities, ensuring a festive, safe celebration for your children’s well-being is important and necessary. Dr. Neeraj Sanduja, MBBS, MS - Ophthalmology, Ophthalmologist, Eye Surgeon shares all about the toxic effects of smoke from the firecrackers kids so lovingly enjoy bursting and how harmful they can be for their eyes.

Hazardous Effects of Firecracker Smoke

The smoke from firecrackers is a blend of toxic chemicals and fine particles, each carrying potential harm for the delicate tissues of the eyes. Here are some key pollutants present in firecracker smoke that pose specific dangers:

Particulate matter: These are the fumes exhaled from burning that are extremely small but can infiltrate deep into the lungs and eyes creating lesions and scars.

Sulfur dioxide & nitrogen oxides: These gasses emit acid rain, it's easy to comprehend how detrimental it is to the human body.

Heavy metals: If consumed through the skin lead arsenic or any other toxic metals emitted through firecrackers will inflict great damage.

Common Eye Conditions Linked to Firecracker Pollution in Children

Exposure to firecracker smoke can cause a range of immediate symptoms in children, as well as chronic eye problems that may not become apparent until much later. Children are at high risk of developing some symptoms upon exposure to firecracker smoke, and these include:

Red eye syndrome: Clinical eye examinations show that the eyes can be red and watery, as well as itchy due to the smoke's chemicals.

Eye pain: Another common complaint in children is a burning and stinging sensation in the eye areas.

Intolerance to light: The burning of firecrackers leads to the emission of smoke that can irritate the eyes and increase their sensitivity.

Corneal damage: Severe inflammation of the outer layer of the eyeball caused by exposure to smoke may be a more damaging injury caused than previously mentioned damages of the inner layer.

Long-Term Effects of Firecracker Smoke on Eye Health

While some eye issues may appear right after exposure, others may develop subtly and manifest over time, resulting in chronic eye conditions. Dr Neeraj exclaims, "Of great concern is the fact that parents may not notice these initial signs and the signs that are causes are others since these are only some of the diseases that are dangerous but children who continuously come into contact with air polluted by firecrackers may consider the following risks:

Cataracts

Glaucoma

Dry eye syndrome

Tips for Protecting Children’s Eyes During Diwali

Parents can observe the following measures to shield their children's eyes from the harmful effects of firecracker smoke:

Avoid exposure: In the first place, the best way to avoid damaging children’s eyes is to prevent any contact with firecracker smoke. Encourage children to remain in the house or in well-ventilated areas during a firework display.

Wear protective eyewear: In the event that children have to go outside during a firework display, they should wear protective eyewear such as goggles or sunglasses.

Rinse eyes thoroughly: In case of exposure of firework smoke to the child’s eyes, the affected eyes should be washed with plenty of clean water.

Seek medical attention: If a child suffers from intense pain in the eyes, redness in the eyes or any changes in vision after exposure to cracker smoke, he/she should be taken to a medical facility as soon as possible.

Parental Guidance During Diwali

1.⁠ ⁠Educate Children on Firecracker Safety

2.⁠ ⁠Monitor Air Quality Index (AQI)

3.⁠ ⁠Plan Indoor Activities During Peak Pollution Hours

4.⁠ ⁠Encourage Healthy Eye Habits (Regular Exams, Hygiene)

Eco-Friendly Alternatives to Firecrackers

1.⁠ ⁠Eco-Friendly Firecrackers

2.⁠ ⁠Laser Light Shows

3.⁠ ⁠Community Events (Parades, Festivals)

4.⁠ ⁠Indoor Games and Activities

5.⁠ ⁠Environmentally Conscious Celebrations

Firecrackers undoubtedly liven up the festivities; however, the use of firecrackers and their impact on the health of children has caused a lot of concern, especially their vision. It has become crucial to protect young developing eyes from fire cracker pollution which is harmful to them, especially in the long run. In this manner, we are able to assist in the preservation of our children’s eyesight and create safe and happy festive occasions for everyone.

Higher education has changed far more than we often acknowledge. Universities are no longer simply places where students earn degrees. They are where young adults spend some of the most formative years of their lives, away from familiar support systems, making independent decisions, navigating uncertainty and, for many, encountering the first signs of a mental health condition. That quiet shift has expanded the role of educational institutions in ways that were never envisaged a decade ago.

The conversation around student wellbeing has evolved alongside this change. Mental health is no longer viewed as a subject to be discussed only after a crisis. Students are speaking more openly, parents are asking different questions, faculty members are becoming more aware and institutions are recognising that emotional wellbeing is closely linked to learning, participation and long term outcomes. This change deserves to be welcomed because it has helped move mental health from the margins of campus life to the centre of institutional responsibility.

Why A Counsellor Alone Is Not Enough?

Yet one assumption continues to shape much of this conversation. The presence of a counsellor is often seen as evidence that a campus is equipped to support student mental health. Counsellors remain indispensable and, for many students, they provide exactly the support that is needed. The challenge arises when counselling is expected to fulfil every role within a mental healthcare system.

Every effective healthcare system is built on layers of expertise. A physician does not replace a surgeon. A laboratory does not replace a diagnosis. Emergency care does not replace rehabilitation. Mental healthcare should be viewed no differently. Counselling is often the first point of contact, but the needs of students do not end there.

Some require structured therapy, others psychiatric evaluation, some ongoing clinical monitoring, and a few immediate crisis intervention. A mature campus mental healthcare system should be equipped to respond across this entire spectrum. The conversation should therefore move beyond whether campuses have counsellors to whether they have a system capable of supporting every stage of care.

Building A Comprehensive Campus Mental Healthcare System

Encouragingly, public policy is beginning to recognise this changing reality. The University Grants Commission’s draft guidelines on mental health and wellbeing for higher educational institutions, with recommendations on counsellor ratios, dedicated wellbeing centres, round the clock helplines and mechanisms for early identification of distress, mark an important step in strengthening institutional support. More importantly, they open the door to a broader conversation on what comprehensive mental healthcare within higher education should look like over the coming years.

Building such a system requires looking beyond individual appointments. One of the most valuable lessons from developing healthcare services is that outcomes are rarely determined by the first consultation alone. They depend on how seamlessly care continues afterwards. If a counsellor recognises that a student needs specialised assessment, how quickly can that happen?

If medication becomes necessary, is psychiatric care available without delay? If a student experiences a crisis outside campus hours, is there a clearly defined pathway to immediate support? If treatment begins, who ensures continuity during semester breaks or after the student returns home? These are not administrative questions. They are questions that shape recovery.

A comprehensive campus mental healthcare ecosystem should therefore bring together different levels of expertise rather than rely on one profession alone. Counsellors, clinical psychologists, psychiatrists, experienced mental health specialists and emergency support services each play a distinct role. Their contribution becomes most effective when they work as part of an integrated network with clear referral pathways, shared clinical responsibility and continuity of care that extends beyond the physical boundaries of the campus.

Prevention And Early Intervention Matter Too

Equally important is recognising that mental healthcare should not begin only after a student seeks help. Institutions have long understood the value of preventive healthcare through regular physical health assessments, vaccination drives and awareness programmes. Mental health deserves the same thoughtful approach.

Periodic, voluntary mental health check ins, appropriate screening, trained faculty and peer support networks, backed by specialist expertise, can help identify concerns early while respecting privacy, dignity and informed consent. Early recognition is not about labelling students. It is about ensuring that support reaches them before distress becomes disabling.

Technology can strengthen this ecosystem, but it cannot replace it. Digital consultations, secure follow up, coordinated records and access to specialists across locations can make care more continuous, particularly for students studying away from home. Their real value lies in connecting different parts of the system rather than functioning as isolated solutions.

Mental Healthcare As Part Of The Institutional Foundation

The quality of a university has traditionally been measured through its academic standards, faculty and research. Increasingly, it will also be measured by how well it supports the people who make learning possible. Mental healthcare deserves to be seen as part of that institutional foundation, not as an additional welfare service that sits alongside education.

The conversation has already moved beyond whether student mental health matters. The next step is to recognise that no single professional, however skilled, can meet every need that students may bring with them. Every campus needs more than a counsellor because every student deserves access to a mental healthcare system that is prepared not only to listen, but also to respond, support and care through every stage of that journey.

By Dr. Jothi Neeraja, Founder, Chairwoman and Managing Director, Maarga Mindcare

Anxiety and depression are major concerns in adulthood, but could nutrition during the earliest stages of life influence health decades later? Two new studies suggest that lower sugar exposure during the first 1,000 days of life may be associated with lower risks of anxiety, depression and even several cancers later in life.

The findings, from studies published in Translational Psychiatry and PNAS point to the potential long-term effects of early-life nutrition. However, the findings do not mean that restricting sugar in infancy directly prevents these diseases.

Sugar Rationing And Mental Health

A 2026 study led by researchers from the University of Surrey, UK, analyzed 46,448 people born between October 1951 and March 1956.

Participants were grouped according to how long they were exposed to sugar rationing: from in utero only to 24 months. People conceived after food rationing had ended served as the main comparison group.

Researchers also analyzed brain MRI data from 5,990 participants.

Lower Risk Of Anxiety And Depression

Compared with people conceived after rationing ended, those exposed to sugar rationing for the three longest periods had significantly lower hazards of both anxiety and depression.

• Shorter-exposure groups did not show significant differences.
• The associations were stronger in women.
• Adult sugar intake was broadly similar across groups, at about 58–59 g/day of free sugar and 122–124 g/day of total sugar.

When later-life sugar intake was considered, the association with anxiety persisted among those exposed throughout pregnancy and the first two years of life, while the association with depression weakened and was no longer statistically significant.

Further, MRI analysis found differences across rationing groups in 80 of 139 gray matter regions. Analysis identified 11 regions that differed from participants conceived immediately after rationing ended, including the brainstem, occipital fusiform gyrus and several cerebellar regions.

Sugar And Cancer Risk

A separate study published in PNAS examined whether sugar exposure during the first 1,000 days could influence cancer risk later in life.

Researchers from China Agricultural University and the University of Cambridge used the abrupt end of UK sugar rationing in September 1953 as a natural experiment. The analysis included 64,761 UK Biobank participants born between 1951 and 1956.

Compared with those whose first 1,000 days were not affected by rationing, participants exposed to rationing showed lower incidence of several cancers:

• Liver/intrahepatic bile duct cancer: 69% lower
• Prostate cancer: 52% lower
• Lung cancer: 41% lower
• Rectal cancer: 40% lower
• Breast cancer: 36% lower

The researchers identified two possible pathways behind the association.

How Could Early Sugar Exposure Matter?

• Long-term dietary habits: People exposed to rationing consumed less sugar, ate smaller quantities and had healthier, more diverse diets even five decades later, suggesting that early-life exposure may influence lasting food preferences.

• Biological ageing: The rationed groups had longer leukocyte telomeres, equivalent to about 2.2 fewer years of biological ageing, along with lower levels of Granzyme B, a marker linked to chronic immune activation.

Sugar's Link With Mental Health And Cancer

Sugar is an important source of energy for the brain, and very low blood glucose can impair brain function. However, excess sugar intake has also been associated with metabolic problems that can affect long-term health.

When it comes to cancer, sugar does not directly cause cancer, and cutting out all sugar does not “starve” cancer cells. Both healthy and cancer cells use glucose for energy.

However, consistently consuming excessive amounts of added sugar can contribute to weight gain and obesity, which are established risk factors for several cancers.

Men who consume higher amounts of dietary nitrite may have a greater risk of colorectal cancer, particularly the type affecting the distal colon, according to a new study published in the Journal of the National Cancer Institute.

The study followed 82,009 middle-aged and older adults in Sweden for more than two decades and identified 3,170 cases of colorectal cancer.

Researchers found that men in the highest category of nitrite intake had a 23% higher risk of colorectal cancer overall compared with those in the lowest category. The strongest association was for for distal colon cancer, where the risk was 50% higher.

The findings were not seen in women, and dietary nitrate was not associated with colorectal cancer in either men or women.

More About The Study

Researchers from Karolinska Institutet in Sweden used dietary information collected in 1997 and updated in 2009 and 2019. They linked this information with Sweden's cancer registry to identify colorectal cancer cases through 2022.

Rather than relying only on participants' diet at the beginning of the study, researchers used repeated measurements to capture changes in nitrite and nitrate intake over time. Among men, the highest versus lowest levels of nitrite consumption were associated with a hazard ratio of 1.23 for colorectal cancer. For distal colon cancer, the hazard ratio rose to 1.50.

Difference Between Nitrite And Nitrate

Nitrite and nitrate are related compounds, but they are found in different foods and behave differently in the body. Nitrate occurs naturally in vegetables, particularly leafy greens, as well as drinking water. Nitrite is also naturally present in some foods but is commonly used as a preservative in processed meat and other animal products.

The researchers found no association between dietary nitrate and colorectal cancer, making the distinction particularly important.

Why Nitrite Could Be A Concern For Cancer Risk?

A possible explanation involves N-nitroso compounds, which can form when nitrate and nitrite undergo chemical reactions in the body. Some N-nitroso compounds are known to be carcinogenic in animals.

The researchers saw that previous studies have also investigated possible links between nitrite exposure and cancers of the gastrointestinal tract. However, the exact biological mechanism behind the association observed in this study remains uncertain.

The researchers also found that the association was specific to men, and they said the reason for this difference is unclear.

Sex Difference Needs More Investigation

The authors noted that the higher risk associated with nitrite intake was confined to men and suggested several possible biological explanations, including differences in oxidative stress and other sex-specific factors.

But they stressed that these mechanisms have not been established as the reason for the finding. The study concludes that further research should examine nitrite and colorectal cancer separately in men and women and.

The study was observational, meaning researchers identified an association between dietary nitrite intake and cancer risk but could not prove a direct cause and effect relationship.
