Have you ever considered how your daily routines affect your vision? While we all link smoking and drinking to lung disease or liver damage, their impact on eye health is commonly disregarded. But these habits may be quietly stealing your vision.

Imagine this: You smoke a cigarette or have some cocktails after work, having no idea that the behaviors are speeding along the development of such conditions as cataracts, macular degeneration, and even blindness. Research indicates that smokers are four times more likely to have age-related macular degeneration (AMD), the most prevalent cause of vision loss. At the same time, excessive drinking removes vital nutrients that promote healthy eyes, causing blurry vision, optic nerve damage, and an increased risk of cataracts.

According to Dr. Ajay Sharma, top ophthalmologist, "The toxicants present in cigarette smoke have the potential to irreversibly damage sensitive eye tissues, and alcohol misuse speeds up vision loss in the long run.

The best news? Saving your eyesight begins with knowledge. Knowing how smoking and drinking affect your vision is the beginning of making better decisions. So go ahead, reach for that next drink or cigarette, and ask yourself: Is it worth risking your eyesight? Let's take a look at the true effect of these habits on your eyes.

We hear plenty about the ill effects of smoking and heavy drinking when it comes to heart disease, lung diseases, and liver disease. Their effects on the eyes, however, are much less talked about. Our eyes, just like all other organs, are prone to harm brought about by these bad habits. Smoking brings with it poisonous chemicals that damage crucial eye structures, and heavy drinking causes nutritional deficiencies and nerve damage, both of which have severe effects on the eyes.

Effects of Smoking on Eye Health

1. Risk of Blinding Eye Diseases

Smoking is a significant risk factor for several diseases that can lead to blindness, including:

Cataracts: Cigarette smoke releases toxic chemicals that speed up oxidative stress, which causes clouding of the lens of the eye. Research indicates that smokers are twice more likely to develop cataracts than non-smokers. Ophthalmologist Dr. Ajay Sharma says, "The harmful substances in cigarette smoke directly harm the lens, and there is a greater chance of cataract formation at an earlier age."

Age-Related Macular Degeneration (AMD): The macula, the retina's central region, which is used for clear vision, degenerates as a result of chronic smoking. Smokers are up to four times more likely than non-smokers to develop AMD, according to research. This condition progressively blurs central vision, making ordinary activities like reading and identifying faces more difficult by the day.

Glaucoma and Optic Nerve Damage: Smoking leads to high eye pressure, weakening the optic nerve and risking glaucoma. "The long-term eye effects of smoking are grave and irreversible, which is why quitting smoking as early as possible is very important," Dr. Sharma adds.

2. Dry Eye Syndrome and Increased Tear Reduction

Smoking interferes with tear production and quality, causing chronic dry eye syndrome. The symptoms are redness, irritation, and discomfort. The cigarette smoke exposure also increases inflammation, which makes it hard for the eyes to stay moist.

3. Diabetic Retinopathy Aggravation

For diabetics, smoking also aggravates diabetic retinopathy, a disease that destroys blood vessels in the eye. This will result in progressive visual impairment, further emphasizing why diabetics should eschew smoking.

Effects of Alcohol on Eye Health

1. Nutritional Deficiencies Leading to Vision Impairment

Long-term drinking drains vital vitamins and nutrients needed for eye health, especially:

Vitamin A Deficiency: Causes night blindness and dry eyes.

B-Complex Deficiency: Compromises optic nerve function, which raises the risk of vision loss.

Zinc Deficiency: Compromises retinal function, lowering clarity and contrast sensitivity.

Excessive alcohol consumption impairs the body's capacity to absorb these vital nutrients, hastening the loss of eye health.

2. Alcohol-Induced Optic Neuropathy

Alcohol abuse may lead to toxic optic neuropathy, which is a condition that involves blurred vision, impairment in color perception, and progressive vision loss. Chronic excessive drinking destroys the optic nerve over a period of time, causing permanent vision loss.

3. Transient and Permanent Blurred Vision

Whereas frequent drinking of alcohol may temporarily cause blurred vision through dehydration and insufficient oxygen flow to the eyes, long-term abuse of alcohol can result in sustained vision complications such as double vision and limited peripheral vision.

Yes, smoking and excessive drinking for many years can result in permanent vision loss. As Dr. Sharma points out, "Smokers are much more likely to get cataracts and age-related macular degeneration, both of which will result in permanent blindness if untreated."

Smoking-related eye disease symptoms are:

Cataracts: Dull vision, blurred color vision, and difficulty with vision in low light.

AMD: Altered or absent central vision, trouble reading, and trouble with identifying faces.

The initial phases of such conditions usually show no signs and symptoms, so frequent eye examinations are essential for early detection and treatment.

Stopping Smoking and Cutting Down Alcohol Consumption

The silver lining is that quitting smoking and cutting down on alcohol intake will substantially reduce the chances of eye-related ailments. Research indicates that people who quit smoking find their eye diseases to progress gradually. On the same note, having moderate alcohol intake and following a balanced diet can safeguard long-term eye health.

Important Steps to Safeguard Your Vision:

• Stop smoking to lower the chance of cataracts, AMD, and optic nerve damage.
• Restrict alcohol use to avoid optic neuropathy and preserve vital vitamins.
• Eat a balanced diet filled with vitamin A, B-complex vitamins, and antioxidants for healthy vision.
• Have regular eye exams to detect and treat vision issues early on.

Performing short and intense exercises that last for about 10 minutes may significantly reduce the risk of colorectal cancer, a British study shows.

Researchers at Newcastle University have found that completing brief workouts increases the concentration of several small molecules in the blood that have previously been linked to reducing inflammation, improving blood vessel function and metabolism.

The findings, which were published in the International Journal of Cancer, also noted that even short bouts of exercise can influence the activity of genes that govern tumor growth and fight against cancer.

Dr Sam Orange, Senior Lecturer in Clinical Exercise Physiology at Newcastle University and lead study author, said of the results, "What’s remarkable is that exercise doesn’t just benefit healthy tissues, it sends powerful signals through the bloodstream that can directly influence thousands of genes in cancer cells.

“It’s an exciting insight because it opens the door to find ways that mimic or augment the biological effects of exercise, potentially improving cancer treatment and, crucially, patient outcomes.

“In the future, these insights could lead to new therapies that imitate the beneficial effects of exercise on how cells repair damaged DNA and use fuel for energy.”

How Does It Work?

Researchers had asked each volunteer to complete a short, intense cycling test that lasted about 10 minutes and collected each of their blood samples which were then meticulously analyzed.

After studying about 249 proteins, the experts found nearly 13 protein had increased in their blood flow after the short exercise including interleukin-6 (IL-6), which helps repair the DNA of damaged cells.

When these exercise-induced proteins were applied to colorectal or bowel cancer cells by the scientists in a lab, they discovered that these new proteins could alter the activity of over 1,300 genes, particularly those who were responsible for DNA repair, energy production and cancer cell growth.

As a result, they concluded that performing even small exercises can activate a set of genes in the body's cells that can support efficient use of oxygen and promote energy metabolism. Additionally, the British researchers also discovered that the cell genes which have been previously associated with rapid cell growth were switched off after working out, suggesting that this might aid in controlling cancerous growths in the body.

What Is Colorectal Cancer?

Colorectal or bowel cancer is a common cancer that forms in the tissues of the colon (large intestine) or rectum, often starting as non-cancerous growths called polyps that turn cancerous over time.

Despite being treatable and preventable, colorectal cancer is currently the second leading cause of cancer-related deaths worldwide. Over 70,000 new cases of colorectal cancer occur annually in India, making it the fourth most common cancer in the country.

Typical symptoms usually include :

• Blood in or on the stool
• Changes in bowel habits (diarrhea, constipation, narrower stools)
• Abdominal discomfort, cramps, gas, or pain
• Feeling that your bowel doesn't empty completely
• Weakness, fatigue, or unexplained weight loss

When temperature drops, so does the moisture even in your skin. This is what leads to a rash or allergies. In fact, with changes in temperature, and winters, our lifestyle changes too, this could also be the reason why we experience a winter rash, or allergies. To understand this better, Health and Me spoke to Dr Navjot Arora, Consultant Dermatologist, Dermaheal Skin and Clinic at Dwarka, Delhi, who explained that allergies and skin rashes tend to increase during winter due to both, environmental factors and changes in skin health. "Cold temperatures and low humidity levels reduce moisture in the air, leading to excessive dryness of the skin. When the skin becomes dry, its natural protective barrier weakens. This makes it more prone to irritation, inflammation, and allergic reactions."

Why Does Winter Weather Increase Chances Of Rashes And Allergies?

The doctor explains that during winter, people tend to stay indoors more, and it also increases their exposure to allergens like dust mites, mold, pet dander, and chemical fumes from heaters and cleaning products. "Limited ventilation and closed spaces allow these allergens to build up, triggering allergic responses and skin rashes, especially in individuals with sensitive skin or pre-existing conditions like eczema."

Cold weather also affects blood circulation to the skin. Reduced blood flow can slow down the skin’s repair process and weaken its defense against irritants and allergens. As a result, chronic skin conditions such as eczema, psoriasis, and contact dermatitis often worsen in winter, leading to itching, redness, flaking, and rashes.

Lifestyle Changes In Winter

Doctor also points out that during winters, our bathing habit changes. Dr Arora says, "Frequent hot showers strip away the skin’s natural oils, increasing dryness and irritation. In addition, wearing heavy woolen or synthetic clothing can cause friction, sweating, and contact allergies, particularly in skin folds, which can further contribute to rashes."

Common Symptoms Of Winter Rashes

• flushing
• swelling
• itching
• flaking skin
• sensitivity
• bumps
• blisters

If not treated well, or in time, it can develop into more serious health threat, especially if you have a family history of

• eczema or another type of dermatitis
• psoriasis
• rosacea
• allergies
• asthma
• sensitive skin

What Are The Cures To Winter Rashes And Allergies?

The rise in allergies and rashes during winter is largely linked to dry weather, indoor allergen exposure, and skin barrier damage. Maintaining proper skin hydration, avoiding harsh soaps, limiting hot water exposure, and wearing skin-friendly fabrics can help reduce the risk of winter-related allergies and skin rashes.

Moisturizers are usually the first line of care for dry skin because they help trap moisture and prevent further dryness. Apply them multiple times a day, especially after bathing or washing your hands. Thicker options like creams or ointments tend to keep skin hydrated longer than lighter lotions.

Petroleum jelly can also be effective, as it forms a protective barrier that seals in moisture. If you prefer to avoid petroleum-based products, alternatives like Waxelene or Un-Petroleum work in a similar way to reduce moisture loss.

Natural virgin oils, such as coconut oil, may help calm irritated skin and restore hydration. Use them on areas that are not acne-prone, and always do a patch test on a small area for 24 hours before wider application.

Oatmeal-based soaps or oatmeal baths can also help soothe dry, itchy skin. You can buy ready-made oatmeal soaps or add finely ground oats to a warm bath and soak for about 10 minutes.

For itching and inflammation, topical hydrocortisone creams, available over the counter or by prescription, may provide relief. Always follow the instructions on the label or use them as advised by a doctor.

The NHS has released updated guidance for people who are currently taking clonazepam, a commonly prescribed medicine that belongs to the benzodiazepine group. According to the health service, clonazepam is often used to control seizures or fits linked to epilepsy, ease involuntary muscle spasms, and help manage panic disorders. It is also prescribed in some cases for people with restless legs syndrome (RLS). NHS Inform notes that “around 1 in 10 people experience restless legs syndrome at some stage in their life.”

Explaining how the drug works, the NHS says it increases levels of gamma-aminobutyric acid (GABA), a chemical in the brain that has a calming effect. By boosting GABA, clonazepam can reduce anxiety, prevent seizures or fits, and relax tight or overactive muscles.

Who Can Take Clonazepam?

Clonazepam is only available on prescription and comes as tablets or a liquid. Most adults aged 18 and over can take either form. In certain cases, children as young as one month old may be prescribed clonazepam to treat epilepsy, as per NHS.

That said, there are situations where extra caution is needed. People who are due to have surgery or dental treatment, those who are pregnant, trying to conceive, or who have sleep-related conditions may be advised to stop taking the medicine. However, these are not the only groups the NHS says should be careful.

Clonazepam is not suitable for everyone. Before starting treatment, patients are advised to tell their doctor if they:

• have ever had an allergic reaction to clonazepam or any other medicine
• have myasthenia gravis, a condition that causes muscle weakness
• have sleep apnoea, which affects breathing during sleep
• have lung, liver, or kidney problems
• have spinal or cerebellar ataxia, which can cause shakiness, poor balance, and slurred speech
• have had problems with alcohol or drug use in the past
• have recently experienced bereavement, depression, or thoughts of self-harm or suicide
• have been diagnosed with a personality disorder
• are trying to get pregnant, are already pregnant, or are breastfeeding
• are due to have a general anaesthetic for an operation or dental procedure

What Are The Side Effects Of Clonazepam?

Like many medicines, clonazepam can cause side effects. Common effects, which affect more than 1 in 100 people, include disturbed sleep such as vivid dreams, feeling sleepy during the day, light-headedness, dizziness, unsteadiness, and muscle weakness.

When it comes to long-term use, the NHS warns that clonazepam can lead to withdrawal symptoms if taken for a prolonged period. Because of this risk, people who have been prescribed the drug for more than four weeks may have their dose reduced slowly when stopping treatment, rather than stopping suddenly.

The NHS also stresses that this is not a complete list of side effects. Patients are advised to read the information leaflet that comes with their medicine for full details.

Clonazepam: Serious Side Effects To Watch Out For

Although uncommon, some people may experience serious side effects while taking clonazepam. The NHS advises contacting a doctor or calling 111 immediately if you notice:

• yellowing of the whites of the eyes or skin, which may be less noticeable on darker skin tones, as this could point to liver problems
• seeing or hearing things that are not there, or believing things that are untrue
• problems with coordination or controlling movements
• swollen ankles, a fast heartbeat, coughing, and extreme tiredness, which could be signs of heart issues
• easy bruising, fatigue, nosebleeds, and breathlessness, which may indicate blood disorders
• changes in mood, such as talking more than usual, feeling unusually excited, restless, irritable, or aggressive, which are more likely in children or adults over 65
• Anyone experiencing memory problems, such as difficulty remembering things or amnesia, is advised to book an appointment with their doctor.

In rare cases, clonazepam can trigger a serious allergic reaction known as anaphylaxis.
