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

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.

Mumbaikars are currently being forced to wade through waterlogged streets, as the city has been receiving heavy rainfall for the last few days.

Floodwater often gets mixed with harmful contaminants like animal waste, animal feces, waste from human settlements, industrial pollutants, and harmful microorganisms, which can lead to serious monsoon infections.

Here’s how one can stay safe after getting exposed to floodwater:

Precautionary Measures After Walking Through Floodwater

HealthandMe spoke to Dr. Murtaza S Bagwala, Head of Emergency Medical Services, Saifee Hospital, Mumbai, about how to keep infections at bay after coming in contact with filthy floodwater.

Pay Close Attention To Your Feet And Legs, Even If They Don't Hurt

When you are in floodwater, there may be sharp objects like broken glass, nails, stones and metal debris around you. You are more likely to come in contact with these objects unintentionally.

Dr. Bagwala recommends, “Small cuts, blisters, or punctures may not be noticed but can lead to infection if bacteria get into the skin. If you see any injury, clean it well, brush on antiseptics and consult a doctor for advice if the wound is deep or dirty.”

Don't Overlook Body Aches Or Fever In The Following Days

As the risk of contracting infections is high during monsoon, do not neglect if you develop flu-like symptoms after coming in contact with contaminated floodwater. The expert warns against dangerous monsoon infections like leptospirosis.

He says, “After contact with water contaminated with the urine of an infected animal (usually a rodent), the early symptoms of leptospirosis may include fever, severe muscle pain, headache, vomiting, chills, or redness of the eyes. The symptoms are very similar to those of a viral disease, so prompt medical evaluation is crucial to avoid complications, such as kidney, liver, or lung involvement.”

Don't Ignore Skin Changes

The doctor also says that if your skin’s colour or texture changes after getting exposed to floodwater, do not ignore it. He says that if the area around the feet or legs becomes red, swollen, painful, warm, discharges pus or the itching persists, it should be treated immediately.

These can be signs of bacterial or fungal infections that need to be treated, especially in individuals with diabetes, poor blood flow, or impaired immune function.

Determine If Your Tetanus Shots Are Updated

As you can get cuts and bruises after walking through floodwater, it is important to stay on top of your tetanus shots.

The expert advises, “Seek health care advice if you have a cut or puncture wound, particularly from a sharp object that was submerged in the water, while walking through the water. Early management of wounds can help avoid complications."

Take Precautions When Eating Or Drinking After Exposure

You are also at risk of contracting gastrointestinal infections after coming in contact with floodwater. Contaminated water may enter your mouth and lead to stomach and intestinal infections or may contact food and lead to food poisoning.

Prevent diarrhoea, vomiting and dehydration by drinking only clean, safe water, eating only freshly prepared food and practicing good hand hygiene before eating.

India has approximately 101 million people living with diabetes, one of the largest such populations in the world. Blood sugar levels, HbA1c targets, and medication compliance tend to dominate the clinical conversation around the condition. What receives considerably less attention, from both doctors and patients, is what diabetes does to the feet, and what the consequences of that neglect look like over time.

How Diabetic Foot Ulcers Develop

Diabetic foot ulcers develop when nerve damage caused by prolonged high blood sugar, referred to as diabetic neuropathy, reduces sensation in the feet. A small cut, blister, or pressure sore that a person without neuropathy would notice and address goes unfelt. In the absence of pain as a warning signal, the injury progresses. Infection sets in. By the time the patient presents for medical attention, the wound has often reached a stage where conservative management is no longer sufficient.

The High Cost of Delayed Treatment

The clinical outcomes associated with delayed presentation are sobering. A 2024 study published in Diabetes and Metabolic Syndrome, drawing on real-world data from a tertiary care facility in India, found that amputation was required in 43.4 percent of diabetic foot ulcer patients. Ten-year mortality among those who underwent amputation reached 30.9 percent, compared to 24.5 percent among those who achieved primary healing.

A 2025 cross-sectional study published in Cureus found a significant disparity in mortality rates between individuals with diabetic foot ulcers and those with diabetes alone, at 231 deaths per 1,000 person-years compared to 182. Globally, 18.6 million individuals develop diabetic foot ulcers annually.

Prevention Requires Daily Foot Care

The gap between the clinical evidence on diabetic foot complications and the attention the condition receives in routine diabetes management is where the preventable harm accumulates. Most patients presenting with advanced diabetic foot disease describe a history of minor symptoms that were attributed to something else, ignored, or left unaddressed because they were painless.

Regular foot inspection, appropriate footwear, avoidance of barefoot walking, and early medical review of even minor foot injuries are the practices that interrupt this progression before it reaches the point of irreversibility. Dedicated foot care clinics are built around exactly this philosophy, bringing together the multidisciplinary expertise needed to catch complications early and treat them before the window for limb salvage closes.

Why Multidisciplinary Care Matters

Eastern India carries a significant share of this burden, with patients across West Bengal, Bihar, Odisha, Jharkhand, and the Northeast frequently facing limited access to the multidisciplinary care that diabetic foot management requires. Diabetologists, vascular specialists, wound care experts, reconstructive surgeons, and rehabilitation teams working in coordination produce outcomes that sequential, single-specialty care cannot consistently achieve. Where such integrated care is available and accessed early, limb salvage rates improve, and amputations are reduced.

The Ministry of Health and Family Welfare’s recent advisory on diabetic foot care reinforces that foot health in diabetes management warrants systematic attention, not as an afterthought to glycemic control, but alongside it.

A small implanted device that stimulates the vagus nerve may offer substantial and lasting relief for people with severe treatment-resistant depression, according to a large multicenter clinical trial.

The findings, published in the International Journal of Neuropsychopharmacology, showed that improvements in depressive symptoms, quality of life, and daily functioning were sustained for at least two years in most patients who responded to treatment.

Notably, more than 20% of treated participants (39 patients) were in remission after two years, meaning their depressive symptoms had improved enough for them to function normally in daily life.

"We were shocked that one in five patients was effectively without depressive symptoms at the end of two years," said lead author Charles Conway, professor of psychiatry and director of Washington University's Treatment Resistant Mood Disorders Center.

Earlier this week, Republican Tom Kean Jr. revealed that he had been diagnosed with depression, explaining his absence from public life for more than 100 days.

He is far from alone. About 20% of U.S. adults experience major depression during their lifetime. While most people improve after antidepressants or psychotherapy, up to one-third develop treatment-resistant depression, in which standard treatments fail to provide adequate relief.

Study Focused on the Most Severe Cases

The RECOVER trial, led by researchers at Washington University School of Medicine in St. Louis, enrolled nearly 500 patients across 84 sites in the US. On average, participants had:

• Lived with depression for 29 years
• Tried 13 unsuccessful treatments
• Undergone therapies including electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS)
• Three-quarters were too ill to work.

"We believe the sample in this trial represents the sickest treatment-resistant depressed patient sample ever studied in a clinical trial," Conway said.

"There is a dire need to find effective treatments for these patients, who often have no other options. With this kind of chronic, disabling illness, even a partial response to treatment is life-altering, and with vagus nerve stimulation, we're seeing that benefit is lasting," he added.

Benefits Lasted for Two Years

The VNS Therapy System, manufactured by LivaNova USA, Inc., involves implanting a small device beneath the skin of the chest. The device delivers carefully calibrated electrical pulses to the left vagus nerve, which serves as a major communication pathway between the brain and internal organs.

Although every participant received an implant, only half had their devices activated during the first year, allowing researchers to compare outcomes.

The latest analysis focused on 214 patients whose devices were activated from the beginning of the study.

Among them:

• About 69% (147 patients) achieved a meaningful improvement in at least one outcome after 12 months.
• More than 80% of those responders maintained or improved those benefits after 24 months.
• Among patients with a substantial response after one year, 92% continued to experience benefits two years later.

Conway noted that even a 30% improvement can dramatically change the lives of patients with severe depression, who often struggle to carry out basic daily activities and face a higher risk of hospitalization or early death.

Some Patients Improved Later

The study also found that recovery may take longer for some people.

Nearly one-third of participants who had not responded after the first year reported meaningful improvements by the end of the second year, suggesting prolonged stimulation may continue to produce benefits.

Researchers also observed consistently low relapse rates among patients who improved, particularly among those with the strongest responses.
