Kids love going around places, playing, and exploring new things. While all of this is fun, it can expose them to diseases. When they come from school, they are exposed to various germs through air and transmission or direct contact. They also touch surfaces a lot, then their face, then their mouths. This makes it easy for illness to spread. While it is impossible to prevent illness completely, there could be several measures that can reduce the risk and support recovery.
Vaccination is a critical step in preventing severe illnesses. The Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) recommend following an established vaccine schedule. Vaccines protect against life-threatening infections, including those that disproportionately affect infants and young children.
While no vaccine can prevent one from common cold, good hygiene practices can significantly reduce germ transmission. Parents must therefore encourage their children to wash their hands after touching toys, hard surfaces, and other people. What is more important is proper hand hygiene, as handwashing with soap and water is the most effective way to eliminate germs.

There are several research that suggests that early exposure to germs may help develop a child’s immune system, a concept known as the "hygiene hypothesis." However, many immunologists argue against this theory, noting that children naturally encounter enough germs to build immunity without unnecessary exposure to unsanitary conditions. A balanced approach ensures children develop a strong immune response without increased risk of illness.
Regular cleaning of toys, school supplies, and frequently touched objects is essential. Understanding the difference between cleaning, sanitizing, and disinfecting can help:
It is important to read product labels carefully, use child-safe cleaning products, and rinse toys thoroughly after disinfection, especially those that go into a child’s mouth.
To minimize germ exposure, parents should clean objects with soap and water first and then use a sanitizer for everyday items. Disinfectants, which are stronger, should be used on objects that a sick person has touched. The Environmental Protection Agency (EPA) provides a list of approved sanitizers and disinfectants that effectively kill germs.
Teaching children proper hygiene without creating fear is essential. Make handwashing engaging by incorporating songs or counting games. Explaining the benefits of hygiene in a positive way helps children understand that washing hands protects them and others. Parents can reinforce these habits by leading by example.
A strong immune system helps children fight infections more effectively. Proper nutrition plays a crucial role in immune support. A balanced diet should include:
Multivitamins are generally unnecessary for well-nourished children, but if supplements are used, they should be free of added sugars and taken under supervision to prevent choking hazards.
Proper respiratory hygiene reduces the spread of illness. Parents should model behaviors such as covering their mouths with an elbow when coughing or sneezing. Using tissues and disposing of them immediately is also a good practice. Reinforcing these habits through positive encouragement makes children more likely to adopt them.

Asthma is one of the most common chronic respiratory conditions in children. Recently, there has been a noticeable increase in cases.
According to the American College of Allergy Asthma and Immunology, the signs of asthma can range from a cough that lingers for days or weeks to a sudden and scary inability to breathe effectively.
Coughing, wheezing, or a whistling sound is often mistaken for a common cold. However, experts warn that these symptoms should not be ignored and advise consulting an allergist.
Dr Shivanshu Raj Goyal, Associate Director & Unit Head - Pulmonology, Max Hospital, Gurugram, told HealthandMe that "increasing levels of air pollution, exposure to allergens, changing weather, respiratory infections, and lifestyle factors are the major reasons behind a surge in asthma cases among children."
Children in urban areas are particularly at risk due to ongoing exposure to vehicle emissions, dust, and indoor pollutants.
Dr. Robin Gupta, Associate Director - Pulmonology, Paras Health Panchkula, also attributed the rising cases of asthma among children to worsening air quality and increased exposure to dust and indoor irritants."
The experts warned that parents should be aware of the early warning signs of asthma. These signs are often mistaken for frequent colds or seasonal allergies.
Symptoms include
Common asthma triggers include
Early diagnosis and timely treatment are crucial to preventing complications. Parents should talk to a pediatrician or pulmonologist if symptoms continue or happen often. Asthma is usually manageable with inhalers, prescribed medications, and avoiding known triggers.
It’s important to know that inhalers are safe and often the most effective way to deliver medication directly to the lungs.
Dr. Gupta told HealthandMe that early diagnosis makes a significant difference, as asthma can be effectively managed with the right treatment.

Amid rising obesity, early diabetes risk, and mental health issues among children, India has expanded its child health screening program to include behavioral disorders and non-communicable disease (NCD) risk factors.
The Ministry of Health and Family Welfare rolled out the screening measures under the revised Rashtriya Bal Swasthya Karyakram (RBSK) 2.0 guidelines.
The guidelines include steps to address mental health conditions and early risk factors for diseases such as diabetes and hypertension. These were released at the recently concluded National Summit on Good Practices and Innovations in Public Healthcare Service Delivery.
The screening services are free and will be delivered through mobile health teams at Anganwadi centers and schools, ensuring universal outreach and early identification.

Children with Type 1 Diabetes Mellitus can develop diabetic ketoacidosis (DKA) if it is not diagnosed on time, since they are insulin-dependent.
Dr. Archana Arya, Senior Consultant Pediatric & Adolescent Endocrinologist at the Institute of Child Health, Sir Ganga Ram Hospital, New Delhi, told HealthandMe that DKA requires hospitalization for treatment, and if undiagnosed, it can lead to coma and death. Early diagnosis reduces morbidity and hospital admissions.
These children present with typical symptoms such as
Type 2 Diabetes Mellitus may or may not present with typical symptoms, and children may develop long-term complications such as retinopathy and nephropathy if the condition goes undiagnosed for a prolonged period.
All overweight and obese children, especially those with a family history of Type 2 diabetes, those with acanthosis nigricans (thickened and dark skin behind the neck and underarms), and girls with PCOS are at high risk of developing Type 2 diabetes and should be screened annually to prevent complications.
The expert added that children with diabetes are at a higher risk of depression (2–3 times higher prevalence), anxiety, and suicidal ideation (in 8–27 percent of youth) due to dietary restrictions and the burden of multiple insulin injections in Type 1 diabetes. Diabetic youth are 1.7 times more likely to attempt suicide, often through insulin overdose.
Dr. Seema Dhir, Unit Head & Senior Consultant, Internal Medicine, Artemis Hospitals, told HealthandMe that good health in early life is essential for preventing non-communicable diseases such as obesity, diabetes, and heart disease. Diabetes is often linked to poor lifestyle and health choices.
Early monitoring, detection, and effective management can reduce the growing burden of diabetes.
Dr. Munia Bhattacharya, Senior Consultant – Clinical Psychology, Mental Health and Behavioural Sciences, Marengo Asia Hospitals, Gurugram, emphasized that preventing non-communicable diseases like diabetes, heart disease, and obesity begins with maintaining both mental and physical well-being.
Providing mental support to children helps them cope better with stress and reduces the risk of anxiety, depression, and suicidal thoughts.
Children who are encouraged to express their feelings and seek help are less likely to experience anxiety, depression, and suicidal tendencies. Early awareness also builds coping skills, decision-making abilities, and healthier lifestyles—paving the way for long-term well-being and a more balanced, confident future.

Babies exposed to pollution, especially vehicle exhaust, during the first trimester of pregnancy had worse language skills at 18 months, according to a study.
The research, published in the Journal of Physiology, found that children exposed to traffic emissions have different brain structure sizes, attributed to pollution exposure in the womb.
Notably, pollution had an even greater impact on babies born pre-term, with this group showing poorer motor as well as language skills.
“We wanted to establish if air pollution levels related to cognitive, language, and motor abilities in this critical period of early childhood. The first 1,000 days from conception to age two shape long-term brain health and behavior,” said lead author Dr Alexandra Bonthrone, from King’s College London.
The team involved 498 infants from Greater London between 2015 and 2020. Of the cohort, 125 were born prematurely, and within that group, 54 were born less than 32 weeks – known as ‘very and extremely preterm’.
Analyzing pollutants like particulate matter and nitrogen dioxide, which are emitted by traffic exhaust, the researchers estimated the amount of pollution mothers were exposed to during pregnancy based on their home postcode.
The infants underwent a standard clinical test of development, known as the Bayley Scales, which measures cognitive, language, and motor skills, with scores of 100 reflecting the population average.
Those exposed to high pollution in the first trimester of pregnancy scored on average 5-7 points lower compared to babies exposed to low pollution on language tests. There was no association with pollution in the second and third trimesters.
Premature babies exposed to the highest pollution levels in the womb across all of pregnancy scored on average 11 points less than those exposed to low levels for motor skills.
Breathing in air pollution is the second largest risk factor for death in children under 5 globally, second only to malnutrition, according to the State of Global Air Report.
According to experts, maternal exposure to pollution increases the risk of miscarriage, pre-term births, stillbirths, birth defects, and congenital heart disease, among others.
Toxic particles can cross the placenta, the temporary organ that links a baby to the mother through the umbilical cord, and disrupt normal development. They trigger inflammation in the placenta, which creates resistance to blood flow. Over time, the blood vessels become damaged, reducing the amount of blood reaching the fetus.
Air pollution can mess with how nutrients reach the baby, which often leads to low birth weight. Research also shows that when a pregnant woman is exposed to polluted air, the risk of stillbirth goes up, especially in the third trimester.
High levels of fine particulate matter (PM2.5) are linked to low birth weight and premature birth, both of which can cause other health problems. Tiny sooty particles can move through the mother’s bloodstream to the placenta and affect the baby’s lung development, raising the risk of lifelong breathing issues like asthma.
Pollutants such as nitrogen dioxide and PAHs, which come from things like burning food, coal, oil, or gas, can disrupt how organs form. This can increase the chances of conditions like congenital heart defects, neural tube problems, or cleft palate. Some studies also suggest that heavy exposure to air pollution during pregnancy may raise the risk of autism spectrum disorder.
Air pollution can also push the mother’s blood pressure up, increasing the risk of preeclampsia, which is dangerous for both mom and baby.
