Why Toddlers Fall Sick During Weather Changes and How to Strengthen Immunity

Many parents observe that their toddlers fall sick and catch cold or have cough, sore throat or stomach problems more frequently as the seasons change. Seasonal variations can affect the body’s natural defences and the spread of viruses but weather by itself doesn’t directly cause disease. The frequency and severity of illnesses can be decreased by strengthening the toddler immune system with a healthy diet, enough sleep, exercise and proper cleanliness.

Why Do Toddlers Fall Sick During Weather Changes?

Many parents think that toddlers fall sick solely because of cold weather, however major causes of seasonal transition cold and flu for toddlers are the increased viral exposure, fluctuating humidity levels, indoor congestion and an underdeveloped immune system. Immune memory is still being developed in toddlers and infections are widespread with seasonal changes because children are often exposed to new viruses in social situations, parks and day care centres. A rise in the spread of respiratory viruses, nose’s protective lining impacted by dry air, variations in temperature putting the body under stress, less sunshine resulting in less vitamin D production and regular interaction with other children are the contributing factors. Toddler immunity may be greatly improved by proper diet and good practices even if infections are prevalent.

How Weather Changes Affect The Toddler Immune System

Throughout early life toddler immune system continues to develop. Environmental changes may put immune defences to the test during seasonal transitions. Mucous membranes that often capture viruses may be less efficient in cold dry air. Children also frequently spend more time indoors which makes it easier for respiratory illnesses to spread. A robust immunological response is reliant upon:

• Sufficient use of energy
• Good protein
• Essential minerals and vitamins
• A healthy microbiome in the gut
• Adequate hydration
• Good quality sleep

Although nutrition is crucial for maintaining healthy immune function it cannot prevent infections on its own.¹

Common Seasonal Transition Cold And Flu Toddlers

Seasonal transition cold and flu toddlers frequently contract many viral illnesses like the common cold, influenza, viral fever ear infection, sore throat or infections of the digestive system. Symptoms might consist of fever, runny nose, cough, decreased appetite, weariness and anger. With supportive care, proper diet and hydration the majority of viral infections get recovered.²

Toddler Nutrition Immunity Foods Role

One of the best pillars of early childhood immunity techniques is nutrition. The energy, protein, healthy fats, vitamins and minerals needed for the development of immune cells and antibodies are provided by a nutritionally balanced diet³ by offering a range of toddler nutrition and immunity foods such as seasonal fruits and vegetables, whole grains, pulses, dairy products, eggs (if eaten), fish (when suitable) and age appropriate nuts and seeds. Picky eaters may find it difficult to regularly achieve their daily nutritional needs. When paired with a nutritionally balanced diet, a nutritional drink like Complan NutriGro can improve total nutrient intake. Complan NutriGro has 34 vital nutrients including DHA which helps in cognitive development. It also provides a balanced 50:50 blend of whey and casein protein with all necessary amino acids for growth and probiotic Bifidobacterium lactis that supports gut health.

Essential Nutrients That Strengthen Immunity

The following nutrients support healthy development and a functioning immune system.

• Amino acids needed for immune cells, muscular development, tissue healing and antibodies are found in protein.
• Vitamin A promotes appropriate immunological function, healthy skin and mucosal barriers.
• White blood cell activity is supported by vitamin C which also works as an antioxidant.
• Vitamin E protects immune cells from oxidative damage.
• Zinc promotes healthy wound healing and immune cell growth.
• Selenium promotes immune responses and has antioxidant properties.
• DHA helps in learning and focus while supporting cognitive development in early childhood.
• Other crucial nutrients like Iron, Vitamin D, vitamins B₆ and B₁₂, folate, calcium, magnesium and copper contributes to healthy growth and overall wellbeing.⁴

Foods To Include Every Day For Toddler Immunity

In toddler nutrition immunity foods parents may create meals that strengthen immunity by including several food groups like fruits (oranges, guava, kiwi, papaya, melons, berries etc), vegetables (spinach, carrots, pumpkin, bottle gourd, broccoli etc), protein (eggs, paneer, yoghurt, dal, chicken etc), healthy fats (from fish, nuts, seeds and age appropriate peanut butter), whole grains (oats, millet, brown rice, whole wheat etc). The carbohydrates, protein, fibre, vitamins, minerals and healthy fats required for child immunity are found in balanced meals.

Healthy Lifestyle Habits For Stronger Toddler Immune System

Immunity is strengthened by a number of daily practices in addition to diet. Parents should promote 10-13 hours of restful sleep, playing outside every day, staying properly hydrated, making sure they clean their hands before eating, regular immunisations, restricted consumption of highly processed meals and less sugar sweetened drinks. The finest support for developing toddler immunity comes from a mix of nutritious diet and healthy practices.

When Should Parents See A Doctor?

See a doctor if your child has any of the following symptoms:

• A fever that persists for more than 3 days
• Breathing difficulties
• Continuous vomiting
• Inadequate hydration
• A decrease in urine output
• Unusual drowsiness
• Recurrent infections that affect growth

Timely medical examination guarantees proper therapy and aids in the identification of problems.

Conclusion

Toddlers fall sick more often because their immune systems are still developing and they are exposed to several different infections as the seasons change. A nutritionally balanced diet full of fruits, vegetables, good protein, healthy fats and nutrients help strengthen immunity and develop resilience even when illnesses cannot always be prevented. Balanced eating to promote healthy growth, brain development and long term immunological health along with adequate sleep, exercise, immunisations and proper cleanliness is still one of the best way for toddler immunity. Consult your paediatrician or qualified dietitian about appropriate dietary alternatives if your child is a picky eater or finds it difficult to satisfy daily nutritional needs. Complan NutriGro, a nutritional drink providing good quality protein from whey and casein with all essential amino acids, and 34 vital nutrients such as DHA, iron, calcium, etc. can support immune function, growth, and cognitive development, when incorporated as part of a nutritionally balanced diet.
