Pet parents would know that your dog is not just a dog, but an integral part of your family. Mental health expert, Dr Dharmesh Shah, founder and director of Holistica World says that having pets can alleviate symptoms of depression and anxiety. It also encourages the person to have a routine and responsibility. "The unconditional love and companionship of a pet provide emotional support, which can reduce stress and increase overall happiness," he says.

"Pets require regular feeding, grooming, and exercise, which instils a sense of duty and foster reliability. The routine of pet care offers predictability, which can be comforting for individuals with anxiety or depression. Additionally, knowing that a pet relies on them can boost self-esteem and foster a sense of accomplishment," he says.

But, Should You Be Sleeping With Them?

In a study published in the Journal of Human Nature, researchers have seen that sleeping in the same room as your pets is not a modern phenomenon, dogs have been domesticated since ancient times. In fact, in some cultures, it is considered beneficial to sleep with animals as it protects you from evil spirits. But what is the science behind it? Should you sleep or not with your dog, on the same bed?

Allergies and diseases

If you co-sleep with your dog, you are prone to developing allergies. Transmission of diseases, from both the dog to the human and vice-versa is possible.

Some studies have also reported that sharing a bed with dogs can lead to disturbances in sleep, which is not the case with people whose pets did not sleep with them. This may be because dogs are polyphasic sleepers, which means they have an average of three sleep and wake cycles per nighttime hour, whereas humans are monophasic sleepers, which means they sleep for one period over a 24-hour cycle.

As per the American Kennel Club, if your dog has signs of aggression, then sleeping together can worsen it.

Benefits of Co-sleeping with your pet

As per Mayo Clinic, 56% of adults sleep with a pet in the bedroom, whereas 35% of children share their bed with a pet. While allergies are one side of the coin, there are also certain benefits associated with co-sleeping with your dog. Allergies can be controlled if your dog is cleaned well, your house follows a regular hygiene routine and the transmission of disease could be limited if your dog is vaccinated.

Comfort and security

There are PTSD dog services that use trained dogs to identify physical signs that indicate a person is having a nightmare or a trigger attack even while sleeping. This is when the dog disrupts the person's sleep to distract them from the trigger attack or the nightmare.

Emotional Support

Seconding with Dr Shah's explanation, having a dog can actually reduce anxiety and loneliness, ease symptoms of mental health conditions and also help in regulating emotions. It can also add sense and purpose to life.

Heightened Immunity

As per Sleep Foundation, the presence of pets can influence the makeup of bacteria found in a home, which can in turn impact the immunity of humans living there. Take it as a vaccine, where weakened or inactive parts of a pathogen or the same virus are used to fight the virus that is causing infection. This happens because the vaccine triggers your body's immune system to produce antibodies and then it recognises and fights off the specific pathogens. Similarly, researchers have hypothesised that exposure to a diversity of microorganisms benefits human health and strengthens immunity.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder affecting social interaction, behavior, and communication. The etiology of autism is yet to be deciphered, although there is burgeoning evidence that an intimate relationship between the gut microbiome and the brain exists. In recent times, researchers have been investigating the possibility of using probiotics—the so-called "good bacteria"—as therapeutic interventions in children with autism. These supplements not only enhance digestive health but also reduce some of the behavioral symptoms, bringing hope to millions of families around the globe.

ASD is highly variable in its signs and symptoms. Some children have speech and communication problems, whereas others have sensory sensitivity or repetitive behaviors. Most have a problem with emotional regulation and social communication. Less openly spoken is that kids with autism very often have gastrointestinal (GI) problems like bloating, constipation, diarrhea, and irritable bowel syndrome (IBS).

Research has shown that people with autism tend to have an imbalance of their gut microbiota, with less healthy bacteria and more pathogenic bacteria like Clostridia. This has prompted scientists to study if normalization of the gut through probiotics would help improve symptoms of ASD.

Role of Probiotics in Gut Health

Probiotics are live bacteria and yeasts that are beneficial to the digestive system. They are present in fermented foods such as yogurt, kefir, kimchi, and miso, and also in dietary supplements. Probiotics assist in keeping the good and bad bacteria in the gut in balance. These good microbes enhance digestion, boost the immune system, and can lower inflammation—factors that may contribute to autism symptoms.

Increased numbers of studies now indicate that probiotics may provide an effective complimentary treatment for individuals with ASD. In a more recent study revealed by the BMJ Journal, it was identified that children consuming probiotic supplements noticed a reduction of 47.77% in behavioral signs. The trial further indicated an attenuation of social withdrawal by 40% as well as the rate of repetition reduced by 37.77%. Further, enhancements in gastrointestinal well-being were observed, such as a rise of 18.18% in formed stools and a decrease of 6.66% in watery stools.

The Autism-Gut-Brain Connection

The brain and the gut are closely linked by the gut-brain axis, a two-way communication network between the nervous system and the digestive system. The US Department of Health and National Institutes of Health (NIH) place significant importance on gut microbiota in postnatal brain development. Scientists feel that alterations in gut bacteria can be responsible for neurological and behavioral abnormalities in children with autism.

Ohio State University Study links kids with ASD were noted to have lower amounts of Faecalibacterium prausnitzii, a gut bacterium linked to good gut health.

Another research stated that how chemicals made by gut bacteria affect autism behaviors.

A 2016 International Meeting for Autism Research (IMFAR) detected Haemophilus parainfluenzae in the stools of autistic children, tying it to gastrointestinal distress and behavioral difficulties.

Based on this evidence, numerous scientists now think that enhancing gut health with probiotics may help ease symptoms of autism.

Probiotics and Digestive Health in Autism

Individuals with autism have a higher tendency to experience GI disorders like IBS and leaky gut syndrome, which results when toxic bacteria and toxins escape into the blood through a weakened intestinal lining. Leaky gut symptoms can be:

• Constipation
• Bloating
• Excess gas
• Nutrient deficiencies
• Food allergies

By restoring the balance of gut flora, probiotics can potentially treat these gastrointestinal disturbances. Probiotic strains including Lactobacillus acidophilus, L. rhamnosus GG, L. reuteri, and Bifidobacterium have been effective in maintaining intestinal health and relieving symptoms of children with inflammatory bowel disease (IBD), a condition typically observed in children with ASD. Saccharomyces boulardii, a probiotic yeast, has also been reported to be responsible for the relief of obsessive-compulsive behaviors, which are characteristically observed in children with autism.

How to Choose the Right Probiotic for Autism?

When choosing a probiotic supplement for an autistic child, parents need to take the following into account:

Strain Diversity: A variety of bacterial strains is best for maintaining gut health.

Scientific Support: Opt for probiotics that have scientific evidence, like Lactobacillus and Bifidobacterium species.

Live Cultures: Make sure the product has active, live bacteria that can withstand stomach acid and travel to the intestines.

Consultation with a Physician: Always consult with a physician prior to the initiation of probiotics, particularly for children with weakened immune systems.

Although probiotics are regarded as safe, side effects can be in the form of slight gas, bloating, constipation, or allergic reactions. Nevertheless, these are generally tolerated as the body acclimatizes to the new bacterial load.

Are Probiotics a Safe and Effective Treatment for Autism?

The US Food and Drug Administration (FDA) oversees probiotics as foods, not as drugs, so their efficacy and safety are not under the same level of intense testing as pharmaceuticals. However, experts in the health field are unanimous in saying that probiotics are safe for children as well as adults when used properly.

Although probiotics cannot be considered a sole treatment for autism, they can be used to augment current therapies like behavioral therapy, speech therapy, and special education programs. Stool analysis can also be used to identify the most appropriate probiotic strains for a child's individual needs so that a customized approach to gut health can be adopted.

Autism can be difficult to handle by families, but research on the gut-brain relationship provides new promise. While researchers keep finding the connection between gut health and neurological function, probiotics can become the hoped-for component in the overall treatment of autism.

Improvements in microbiome science, as well as greater knowledge of probiotics, are a giant leap toward enhancing the quality of life in ASD-affected children. Although larger clinical trials are necessary to delineate the role of probiotics in autism treatment comprehensively, the early results are promising. Parents willing to use probiotics for the child should visit a healthcare practitioner to decide on the most suitable method for their child's specific requirements.

A regular manicure became a lifesaver for 58-year-old Michelle Tagliamonte of Centreville, Ohio. What appeared to be a minor cosmetic issue—a strange black line on her thumbnail—proved to be an early warning sign of melanoma, one of the most dangerous types of skin cancer. Her experience highlights the value of being attentive to changes in your body and seeking medical advice when things do not feel right.

Tagliamonte, like many others, had a regular beauty routine. She visited a nail salon every four weeks for a manicure, a routine she followed without much thought. Yet, at the time of her last September visit, she noticed something odd—thin black lines on her right thumbnail. She initially dismissed it, thinking that nothing was wrong.

"I typically get my nails done every four weeks, so I don't know how long it had been there," she remembered. "But my nails grow pretty quickly because I have really good nutrition. It could have been there for six months or longer."

She snapped photos of the lines and went on with her nail appointment, unaware that this apparently insignificant detail was an indicator of something much more severe.

As the weeks went by, Tagliamonte observed that the lines did not extend out with her nail as she had anticipated. Rather, they stuck at the base of her thumbnail and appeared to be getting deeper. By the time her next appointment arrived, the marks persisted—unchanged and unerased.

That was the wake-up call. Not taking any chances, she went to see a doctor. Over Thanksgiving, the results revealed her worst fears—the black lines were evidence of melanoma, stage zero or 'melanoma in situ.'

What is Stage Zero Melanoma?

Stage zero melanoma, or 'melanoma in situ,' is a situation where the cancer cells remain in the epidermis and have not extended beyond it. Although it is the most treatable and earliest stage, it can become invasive melanoma, spreading to other regions of the body and threatening life, if it goes undiagnosed.

Physicians moved quickly to eliminate the cancerous cells before they had a chance to disperse. On January 17, Tagliamonte received a four-hour surgical procedure in which physicians amputated her entire thumbnail. To reattach the damaged area, a skin graft was conducted using tissue from the rest of her thumb.

The dermatologist noticed discoloration at the bottom of my nail," she said. "Whatever was producing this black line was originating from within the growth plate, way down deep inside my nail.

The procedure was invasive and complicated. The melanoma extended down to the first knuckle of her thumb, and a considerable amount of tissue had to be removed. The exposed bone and tendon were covered with the skin graft to allow the area to heal. Although she permanently lost her thumbnail, Tagliamonte is thankful for the timely medical intervention that left her alive.

Tagliamonte attributes her routine manicure sessions and her own vigilance for detecting the disease before it advanced to a more serious phase.

"The nail appointment definitely saved my life," she stressed. "I am thankful that I noticed it and then went about having it checked out."

Her experience is an eye-opener that even slightest changes in the body, whether seemingly innocuous, can prove to be signals of major illness at times. She now prefers others to be alert and hearken to instincts.

If you notice something unusual or different, listen to your own instincts and have it looked at," she warned. "If I'd have ignored it, Lord only knows what might have happened to me in the future."

Hidden Dangers of Nail Health and Exposure to the Sun

Tagliamonte's account also makes one mindful of other health hazards of nail care. Numerous individuals are not aware that dark or black stripes in the nails can be markers of hidden underlying medical conditions. At times, such markings could be a consequence of a disorder known as subungual melanoma, an infrequent yet malignant form of skin cancer beneath the nail.

Moreover, experts caution against the dangers posed by the UV lamps that are employed in certain professional manicures to harden gel nail polish. Such machines release UVA rays, which penetrate deep into the skin, heightening the risk of skin cancer with extended exposure.

"Too much exposure to UV light can harm the DNA of skin cells, causing them to grow out of control and form tumors," say dermatologists. "UVA and UVB radiation both help cause skin cancer, though UVB is more directly responsible for sunburn, with UVA causing more long-term harm and hastening the skin's aging process."

Uncommon Signs of Melanoma

Although melanoma is usually linked to moles and skin lesions, Michelle Tagliamonte's situation featured a number of uncommon warning signs:

Black Stripes on the Nail – Rather than a visible skin lesion, she saw dark stripes along her thumbnail, a less common symptom of subungual melanoma.

No Discomfort or Pain – Most people expect cancerous tumors to be painful, but Michelle felt no pain, making the diagnosis even more surprising.

Slow and Steady Growth – The streaks did not fall out or simply grow out with her nail, an indication that there was something amiss.

Concealed Source – The melanoma was growing from the growth plate of the nail underneath, hence hidden at first.

Stage Zero Diagnosis – Despite the alarming signs, the melanoma was actually in its earliest stage, illustrating how intervention at this point could avoid fatal effects.

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.
