Happy And Safe Diwali: How Smoke From Firecrackers Puts Children's Vision At Risk
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.
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.
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.
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:
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.
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)
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.

Indian Actress Dipika Kakkar, battling liver cancer, underwent another surgery last month for a 1.3 cm cyst that reappeared.
Best known for her role as Simar Bhardwaj in the hit TV show Sasural Simar Ka, Dipika underwent a major tumour-removal surgery in June 2025. She also undertook chemotherapy
In her latest vlog, Dipika shared that the unexpected recurrence has left her feeling anxious and overwhelmed as doctors evaluate the next course of treatment.
"The recurrence that happened with the 1.3 cm cyst has shaken me. I am a little scared now that it shouldn't happen again. I have started dieting, but I feel anxious," she said.
HealthandMe spoke to health experts to understand why cysts recur in liver cancer patients and how it's important to keep monitoring them.
According to health experts, a biannual liver scan is imperative, and it can detect signs of cysts.
“Simple cysts less than 2-3 Cm can be observed with repeat scans every 6 months to 1 year. Suspicious or malignant cysts need surgical resection and oncological treatment based on the histopathology and patient condition,” Dr Manjunath NML, Sr Consultant, Surgical Oncology and Robotic Surgeon, HCG Cancer Hospital, K R Road, Bengaluru.
Liver cysts are like bags that are filled with fluid. They are usually not cancer. Most people who have liver cysts do not get cancer.
However, just because one has a cyst, it does not mean it's cancer.
“Cysts in the liver are typically harmless and unrelated to liver cancer. However, unusual types of cysts may suggest malignant changes that need further examination, particularly among risk groups,” Dr. Govind Nandakumar, Consultant – Gastrointestinal Surgery, Manipal Hospitals Hebbal, told HealthandMe.
The experts noted that cases of recurring cysts related to liver cancer are uncommon. But they occur because of

Many liver cysts do not cause any problems in the early stages. That is why regular check-ups with a doctor are important. If a cyst grows or becomes problematic, symptoms may begin to appear. These can include
Recurrent cysts can be effectively managed and treated over time. The recurrence does not necessarily imply the progression of the condition itself; however, more tests may be required to determine whether cysts are malignant or benign.
“Cysts with thick walls, septations inside, and solid components in them are more likely to be cancerous. If the cysts are large, they cause symptoms like pain, distension, and obstruction of the bowel or biliary tract,” Dr Manjunath said.
The experts explained that diagnosis can be achieved by scans like ultrasonography, Computerized Tomography CT or Magnetic Resonance Imaging (MRI). Suspicious cysts must be checked via biopsy to confirm malignancy.
While suspicious or malignant cysts require surgical resection and oncological treatment, symptomatic cysts, even if benign, may also require removal.
However, if a liver cyst is detected without suspicious features and is asymptomatic, it usually does not require any intervention, Dr. Manjunath noted.

What if the body whispers long before it screams? For many living with Parkinson’s disease, the earliest signs are not the tremors, but quieter changes, such as a diminished sense of smell, disrupted sleep, or gut problems. The challenge is that we are conditioned to look for the disease only once it becomes visible.
Parkinson’s disease, commonly referred to as a movement disorder, progresses slowly due to the destruction of the nerve cells in the brain.
To understand Parkinson’s disease, think of the brain as a command center where certain nerve cells produce dopamine, a chemical messenger that helps coordinate smooth movement. As these dopamine-producing cells gradually deteriorate, the brain’s signalling system gets disturbed, leading to slower movements, mistaken for normal ageing.
The majority of patients experience subtle early signs much before diagnosis, including a reduced sense of smell, sleep disturbances like insomnia, and persistent digestive problems like constipation. In these cases, timely intervention can reduce movement disability by roughly 40 percent.

Conventional treatment focuses on medications that boost dopamine levels, but over time, their effectiveness may decline. When drugs are no longer sufficient, doctors may recommend Deep Brain Stimulation (DBS), a surgical approach that works like a pacemaker for the brain and uses chest-connected electrodes to reset faulty signals causing stiffness and tremors.
Unlike fixed traditional stimulation, the advanced Adaptive DBS (aDBS) listens to brain signals in real-time to adjust therapy automatically. Its single threshold mode reacts instantly, boosting stimulation the moment brain signals hit a specific limit and turns it off just as fast once they improve.
Alternatively, its double threshold mode keeps stimulation steady within the safe zone," making only gradual tweaks if signals cross upper or lower limits. This smart system mimics the body’s natural rhythm to provide fluid symptom control while preventing overstimulation, ultimately helping you reclaim more "good" time and independence.
There is no single ‘Parkinson’s diet,’ but certain food choices can help manage symptoms and overall well-being. A balanced diet rich in fruits, vegetables, and whole grains supports general health and may help reduce inflammation.
Plant-based flavonoids, present in berries, citrus fruits, and broccoli, which have antioxidant effects, can help protect brain cells from damage. Drinking enough water can support digestion and prevent dehydration.
Ultimately, small, consistent dietary choices, combined with medical guidance, can make a meaningful difference in managing symptoms.
Parkinson’s disease is a journey, and the earlier the signs are recognized, the better the condition can be managed. If you or a loved one is experiencing persistent changes in sleep, smell, or movement, do not wait for the symptoms to become overwhelming. Consulting a neurologist is the first step toward taking back control of your health.

While salt, cholesterol, and obesity are major factors driving high blood pressure, a recent study suggests they may not be the only causes.
Researchers from Brazil and New Zealand have identified a brain region that may increase the risk of hypertension. The study, published in the journal Circulation Research, showed that the brain region called the lateral parafacial region is the culprit.
The lateral parafacial region sits in the brainstem – the oldest part of the brain – which controls automatic functions such as digestion, breathing, and heart rate.
“The lateral parafacial region is recruited into action, causing us to exhale during a laugh, exercise, or coughing,” said lead researcher Professor Julian Paton, from the Centre for Heart Research at Waipapa Taumata Rau, University of Auckland.
“These exhalations are what we call ‘forced’ and are driven by our powerful abdominal muscles. In contrast, a normal exhalation does not need these muscles to contract; it happens because the lungs are elastic,” Paton added.
Paton and the team found that the lateral parafacial region also connects to nerves that tighten blood vessels -- a mechanism that raises blood pressure.
“We’ve unearthed a new region of the brain that is causing high blood pressure. Yes, the brain is to blame for hypertension!” Paton said.
“We discovered that, in conditions of high blood pressure, the lateral parafacial region is activated and, when our team inactivated this region, blood pressure fell to normal levels.”
The team explained that this means changes in breathing patterns – especially those involving strong abdominal muscle contractions – can trigger high blood pressure. Thus, any diagnosis of abdominal breathing in patients with high blood pressure may reveal the cause and hence direct appropriate treatment.
The next question was whether the brainstem region could be treated with a medication.
“Targeting the brain with drugs is tricky because they act on the entire brain and not a selected region such as the parafacial nucleus,” Paton said.
The researchers then discovered that this region is activated by signals from outside the brain – from the carotid bodies, tiny clusters of cells in the neck near the carotid artery that sense oxygen levels in the blood.
These can be targeted safely with medication, they said.
“Our goal is to target the carotid bodies, and we are importing a new drug that is being repurposed by us to quench carotid body activity and inactivate ‘remotely’ the lateral parafacial region safely, i.e., without needing to use a drug that penetrates the brain.”
This finding could lead to new treatments for high blood pressure, especially for people who also have sleep apnea, as we know carotid bodies are activated in these patients when they stop breathing at night.
Hypertension is commonly referred to as the "silent killer" due to its lack of noticeable symptoms. Unchecked, it progressively damages your arteries and vital organs.
It occurs when the pressure in your blood vessels is consistently higher than normal—usually 140/90 mmHg or more, states the World Health Organization (WHO). The normal and healthy level is estimated to be 120/80 mmHg. Blood pressure increases when the arteries get narrow or stiff, causing the heart to work harder.
At a global level, an estimated 1.28 billion adults aged 30 to 79 years have hypertension, and most of them live in low- and middle-income nations. Alarmingly, 46 percent of them do not even know they have it, and just 1 in 5 keeps it under control, as per WHO statistics.

In the US alone, the Centers for Disease Control and Prevention (CDC) estimates that nearly 47 percent of adults, or roughly 116 million individuals, have hypertension, yet only 24 percent control it well. The economic burden is just as overwhelming, with the US spending $131 billion each year on care related to hypertension.
Exercise, lifestyle changes, and diet are key to preventing hypertension
