Winter is here, which means the season of sickness too is here. While viruses and sickness run throughout, winter is when the chilly weather further makes it worse for those prone to sickness. Especially, if they are kids, as their immunity is not fully developed.

Does that mean it is inevitable for kids to be sick?

Anytime a child is exposed to another child, they will fall sick. This is because germs are transferred in the air or by touch, and children, being curious, always touch things, including their own faces, mouths and easily pick up germs and spread them. While prevention is impossible, there are steps that can be taken to reduce this.

Experts and medical professionals recommend to follow the vaccine schedule by the Centers for Disease Control (CDC) and American Academy of Pediatrics (AAP). Vaccines have be proven to protect people, children, and infants from serious and deadly infections.

While sicknesses like a common cold do not have a vaccine, good hygiene can help prevent the spread of germs. Teaching your kids to wash hands after touching toys, or any other surface and other people is a great way to start it.

Exposure to germs at an early age strengthens child's immune system

Is there really any truth in the statement? When we encounter infections, our immune system creates antibodies that either prevent future infections or help the body fight them off more effectively, often leading to milder illness. The "hygiene hypothesis" proposes that living in an overly clean environment might hinder the immune system's development, potentially increasing the risk of allergic conditions like asthma.

Although research has explored this idea, many immunologists (experts in the immune system) have raised concerns and expressed disagreement with the hypothesis.

In reality, most children don’t grow up in sterile environments. They are naturally exposed to a variety of germs, providing ample opportunities for their immune systems to strengthen and adapt.

Sanitizing Child's Toys

It is a good practice to regularly disinfect your children's toys and anything they share with others or take to school.

It is important to know the difference between cleaning, sanitizing, and disinfecting. While cleaning removes visible dirt, sanitizing decreases the number of germs on the surface, whereas disinfecting kills germs.

Also make sure to read the labels correctly and prevent any toxic toys to make its way to your kids, so it cannot be inhaled or ingested.

How to disinfect toys?

You can start by cleaning all the toys that has come in contact with your child's hands and mouth with soap and water. Then, use a sanitizer to clean everyday items, things that remain in your child's environment. Then use disinfectant, especially if your child is sick or if someone sick has touched your child's toys.

If you are wondering which sanitizers to go for, the Environmental Protection Agency (EPA) website has come up with a list of approved sanitizers and disinfectants that are effective.

Vitamins and minerals are often consumed for better health and immunity, but a new US study is drawing focus to a danger that may get overlooked. The danger is toxicity if vitamins and minerals are ingested in excessive quantity, particularly for children.

Researchers found that 1,961 children were hospitalised for vitamin and mineral toxicity over a three-year period, according to findings presented at the Pediatric Hospital Medicine 2026 meeting in Kansas City, Missouri.

The researchers used data from the federal Healthcare Cost and Utilization Project Kids’ Inpatient Database, which captures hospital admissions involving children across the US.

But the figure may represent only a part of the problem. “Our study probably only scratched the surface,” lead researcher Marina Masciale, MD, MPH, of Baylor College of Medicine, said while presenting the findings.

Most Poisoning Cases Were Due To Intentional Ingesting

One of the most interesting findings was that the majority of hospital admissions due to vitamin and mineral toxicity was due to intentional ingestion.

That makes the issue different from a child accidentally swallowing one or two tablets. Researchers say the findings highlight the need to consider supplements when assessing children who may deliberately ingest potentially harmful substances.

The database also captured only supplements for which there was a specific toxicity-related ICD-10 diagnostic code. This means poisonings involving supplements that were not coded in this way may not have been included. As a result, the researchers believe the true number of affected children could be substantially higher.

Why Are Children Getting Poisoned If Vitamins Are Supposed To Be Safe?

The body requires many micronutrients in relatively small quantities. Some can become harmful when taken in excessive amounts, particularly certain fat-soluble vitamins that can accumulate in the body.

Minerals can also cause toxicity when consumed in excessive quantities. The symptoms and severity depend on the substance, dose and how quickly treatment is provided.

This is why supplements should not be popped like harmless candies simply because they are sold over the counter.

Why Children Are Particularly Vulnerable?

Many supplements also come in colourful, flavoured or chewable forms, making them particularly attractive to younger children.

But the new findings highlight another concern: older children and adolescents may deliberately consume large quantities of supplements, meaning prevention cannot rely only on keeping bottles out of reach.

Parents and caregivers should therefore store vitamins, minerals and other supplements securely and treat them like medicines rather than everyday food products.

What Should Parents If They Suspect An Overdose?

If a child may have swallowed a large amount of vitamins or minerals, parents must not wait for symptoms to appear.

The exact risk depends on what was taken, how much was consumed and the child’s age and weight. Some toxic effects may not be immediately evident.

Medical professionals may need information from the supplement label, including the ingredients and strength, to determine the appropriate treatment course.

Arthritis is often associated with ageing, but it can also affect children. The most common form of chronic arthritis in children under 16, including those as young as 1, is Juvenile Idiopathic Arthritis (JIA).

Because its early symptoms can be subtle, JIA often goes unrecognized, delaying diagnosis and increasing the risk of joint and growth-plate damage.

Children May Not Say They Are In Pain

Young children may not know how to describe joint pain. Instead, they may change their behavior to avoid discomfort, making it important for parents to notice changes in movement and activity.

A toddler may limp, take longer to get ready or become less active, Dr. Rashmi Jinnakeri, Consultant Pediatrician, Apollo Hospital, Bengaluru, told HealthandMe. These signs may be mistaken for a viral infection, growing pains or simple clumsiness.

Signs Parents Should Watch For

Unlike an injury, JIA symptoms tend to persist, Dr. Chirag Rajkumar Kopp, Consultant – Clinical Immunology & Rheumatology, Ramaiah Memorial Hospital, told HealthandMe.

Parents should watch for:

• Joint pain or swelling lasting more than six weeks
• Morning stiffness that improves during the day
• Neck or lower back pain with stiffness
• An unexplained limp
• Recurrent fever without an obvious cause
• Skin rashes
• Red eyes or sensitivity to light

Morning sluggishness:

A child who normally wakes up energetic may suddenly take much longer to get out of bed, get dressed or start moving. Similar stiffness or sluggishness may occur after an afternoon nap. This can be one of the more subtle signs of JIA in young children.

Sudden clumsiness:

Parents may notice a child dropping objects, tripping, coloring messily or struggling with buttons and zips. Subtle limping after waking may also occur and can improve as the day progresses.

Avoiding play and physical activity:

Children may begin avoiding sports, physical education or activities they once enjoyed. A child who previously loved running and jumping may increasingly prefer to sit or find reasons not to participate.

Going back on milestones:

Some toddlers may show regression in movement. A child who was walking may start crawling again or frequently ask to be carried. Mild swelling, particularly around a knee, can also be overlooked. If only one joint is affected, parents may assume the child bumped it while playing.

Fatigue, fever and rashes:

Some children may appear unusually tired, have low energy or repeatedly say they cannot walk. Fleeting rashes with fever may be mistaken for viral infections. Repeated low- or high-grade fever without cough, cold or vomiting can also occur.

Growing Pains vs Juvenile Arthritis?

Children may describe both conditions simply as “leg pain”, making the distinction difficult, Dr. Rashmi said.

Growing Pains

• Usually occur later in the day after physical activity
• Often affect the thighs, calves or shins
• May improve with massage
• Do not cause joint swelling or redness
• Are usually gone by morning

Juvenile Arthritis

• Is often worse in the morning
• Causes joint-related pain and stiffness
• May cause swelling or redness
• Can improve with movement
• Persists over time, potentially for six weeks or longer

Early Diagnosis Matters

JIA occurs when the immune system mistakenly attacks healthy joints, causing inflammation. The exact cause is not known.

“When this goes unrecognized for too long, the effects don't simply fade with time. Joint damage can become permanent; a child's growth can be affected, and the disability that follows may last well into adulthood,” Dr. Chirag said.

Early treatment with disease-modifying antirheumatic drugs (DMARDs) and, when needed, biologic therapy can control inflammation and help prevent lasting damage. With early recognition and treatment, most children can achieve symptom control and continue to run, play and grow without limitation.

A blood test is considered the first step towards fertility enquiries, but for many, the results might seem like a confusing jumble of numbers and acronyms. Reports sometimes contain terms like AMH, FSH, LH, AFC, and estradiol, which can confuse patients into thinking that a single "abnormal" figure indicates they are unable to conceive.

The truth is more reassuring, and more nuanced. Fertility experts stress that a single test cannot ascertain a person's fertility. Instead, these markers serve as parts of a bigger picture, assisting fertility specialists in comprehending reproductive health and suggesting the best course of action when necessary.

Fertility tests are guides, not verdicts

The idea that a single blood test can determine whether a woman would naturally become pregnant is one of the most widespread myths. Age, egg quality, ovulation, sperm health, uterine health, lifestyle, and underlying medical issues are some of the factors that actually affect fertility.

Although diagnostic markers offer useful information, they must always be interpreted in conjunction with the couple's overall reproductive profile, clinical history, and ultrasound results.

Understanding the ovarian reserve 'AMH'

Anti-Müllerian Hormone (AMH) is perhaps the most talked-about fertility marker today. It is produced by small follicles present in the ovaries. AMH reflects ovarian reserve, which identifies the estimated number of eggs remaining in the ovaries. High AMH indicates larger ovarian reserve, whereas lower levels suggest fewer eggs. However, it can neither measure egg quality nor guarantee the ability to conceive naturally.

Many women with low AMH can still achieve successful pregnancies, especially if they continue to ovulate regularly. Similarly, women with high AMH are not necessarily more fertile; elevated AMH levels in women also mean Polycystic Ovary Syndrome (PCOS), where ovulation may actually be irregular. For fertility specialists, AMH is useful in predicting the number of eggs that are likely to respond to ovarian stimulation medication, based on which they customize IVF treatment.

FSH determines ovarian function

Our pituitary gland produces Follicle Stimulating Hormone (FSH), and this hormone helps in stimulating egg development.

Usually, the second or third day of the menstrual cycle is when FSH is measured. If ovarian reserve is reduced, higher-than-normal levels may imply that ovaries need more stimulation to mature eggs. From cycle to cycle, the FSH levels change.

LH and the ovulation story

FSH and luteinizing hormone (LH) cooperate to control ovulation. The ovary releases a developed egg in response to an increase in LH. LH levels may be disproportionately greater than FSH in PCOS-affected individuals, which can lead to irregular menstrual periods and ovulation. Instead of using LH alone, fertility specialists assess it in link with other hormone markers.

Estradiol and AFC: Completing the picture

An indicator of ovarian activity during the menstrual cycle is estradiol (E2), a type of estrogen generated by growing follicles. Combined interpretation is crucial since elevated early-cycle estradiol levels can occasionally conceal an elevated FSH.

The Antral Follicle Count (AFC), which is done via a transvaginal ultrasound, is another crucial evaluation. AFC gives an additional indication of ovarian reserve by counting the number of visible tiny follicles in the ovaries.

Indeed, the combination of AMH and AFC provides a more thorough insight than any test by itself.

Fertility evaluation isn't just for women

Female hormone testing frequently receives greater attention, whereas male fertility contributes to roughly half of all infertility issues. A semen screening remains one of the most significant and cost-effective tests, measuring sperm count, mobility, and morphology. When necessary, additional hormonal or genetic tests might be suggested.

Era of self-diagnosis

After getting a test report, many people search the web for quick answers, but those numbers without proper medical context from a specialist can cause unnecessary tension. The fertility markers depend on a variety of factors, some of which include: age, weight, menstrual history, prior pregnancies, medications, hormonal status, and lifestyle. Therefore, understanding parameters like “low” or “high” online may create confusion for individuals. Instead, consult a fertility specialist to decode the report.
