An occasional cough is a natural response to irritants in your throat and airways. It's a protective mechanism designed to clear out foreign particles, mucus, and other substances that may have entered your respiratory system. Your body's natural defense system includes tiny hairs called cilia that line the airways. These cilia move in a coordinated manner to sweep away mucus and trapped particles. When irritants or excess mucus accumulate, the cough reflex is triggered to expel them.

However, a persistent cough can be a sign of an underlying health issue. It's important to differentiate between a normal, occasional cough and a chronic cough that may require medical attention. If your cough is accompanied by other symptoms such as fever, shortness of breath, chest pain, or wheezing, it's advisable to consult a healthcare professional.

Common Causes of Coughs

Frequent coughing and wheezing can be indicative of various respiratory problems. Here are some potential causes

Upper Respiratory Infections: These are the most common cause of coughs and include colds, flu, and laryngitis. Viruses are typically responsible for these infections, which often lead to a sore throat, runny nose, and fever. The body's immune system usually fights off these infections within a week or two.

Allergies: People with allergies, such as hay fever, may experience a dry cough, sneezing, and runny nose. Allergic reactions occur when the immune system overreacts to harmless substances like pollen, dust, or pet dander. Antihistamines and decongestants can help alleviate allergy symptoms.

Irritants: Exposure to irritants like smoke, pollution, or strong fumes can irritate the throat and airways, leading to a cough. Reducing exposure to these irritants is essential for preventing cough.

Lower Respiratory Infections: These more serious infections can affect the airways (bronchitis) or the lungs (pneumonia). They can be caused by both viruses and bacteria and often result in a deep, lingering cough, fever, and difficulty breathing. Antibiotics may be necessary to treat bacterial infections.

Pulmonary Embolism: This is a potentially life-threatening condition where a blood clot travels to the lungs, blocking blood flow. It can cause sudden shortness of breath, chest pain, and a dry cough. Prompt medical attention is crucial for treating pulmonary embolism.

Lung Collapse: A pneumothorax occurs when the lung partially or completely deflates. This can be caused by trauma, underlying lung conditions, or spontaneous rupture. Symptoms include sudden chest pain, dry cough, and shortness of breath.

Heart Failure: When the heart is unable to pump blood effectively, it can lead to fluid buildup in the lungs, causing congestion and a cough. Treatment for heart failure focuses on managing the underlying condition and relieving symptoms.

Post-Nasal Drip: Excess mucus draining down the back of the throat can irritate the airways and cause a cough. This condition is often associated with allergies, sinus infections, or acid reflux.

Gastroesophageal Reflux Disease (GERD): When stomach acid flows back up into the esophagus, it can irritate the throat and cause a cough. Medications and lifestyle changes can help manage GERD.

Types of Coughs

Productive Cough brings up phlegm or mucus, which can be a sign of an infection like pneumonia or bronchitis. The color of the mucus may provide clues about the underlying cause. For example, green or yellow mucus often indicates a bacterial infection. Dry or Nonproductive Cough doesn't produce mucus. It can be caused by various conditions, including allergies, asthma, or acid reflux.

April 2 is celebrated worldwide as “Autism Awareness Day” and April as Autism month to create awareness and promote inclusivity and acceptance in society for individuals with autism.

So what exactly is Autism, and why do we need to create a culture of awareness and acceptance?

As per DSM V (Diagnostic and Statistical Manual of Mental Disorders) criteria, in simple terms, there is poor eye contact, impaired social communication skills, repetitive patterns (certain movements or fixation on certain toys, objects), difficulties with sensory processing - extreme sensitivity to sensory inputs (dislike loud noises, sensitive to touch), etc.

As a child, these individuals may not respond to name-calling, have poor eye contact/lack gestures like pointing, etc., lack imagination in play, and may not be able to relate and respond to the emotions of others. They have set routines and dislike changes to their routines. All this can cause significant disruption to their day-to-day functioning.

This year’s theme of -Autism and Humanity- Every Life has Value” reiterates the need for inclusion of autism, ensuring equitable representation of these individuals. Ensuring that society not only recognizes them but also treats them with equal respect and dignity.

Educational Support and Inclusive Workplace

Sarva Shiksha Abhiyan (SSA) was one of the Government's flagship programs, along with Action for Autism, to disseminate information in schools regarding inclusive education for autism. Education is a key foundation to ensure children with autism get suitable opportunities as adults. Special educators, with additional support in schools, can go a long way in ensuring their potential is maximized.

Many IT giants like Microsoft, Google, and SAP encourage tapping the potential of individuals with autism and their exceptional skills. In our country, organizations and NGOs, including Action for Autism, offer training for future employment opportunities.

There is a spectrum of Autistic Spectrum Disorders (ASD) known as Asperger’s syndrome, and these individuals have normal to above average intelligence and can have some exceptional skills, and the world includes some living examples of these with a higher IQ, some of whom are the most successful and famous personalities. Even on the other end of the spectrum, autistic individuals have exceptional skills, some of which include great attention to detail, creativity, problem-solving, and lateral out-of-the-box thinking.

Options for flexible working hours (part-time), understanding their need for routines, and explaining them beforehand regarding important changes to schedules can help them adapt better to an otherwise challenging workplace.

The Need For Sensitization

Understanding individuals with autism may need little extra support, being a little flexible with time deadlines, giving simple instructions, especially written/visual ones, and allowing them time to overcome their communication barriers can go a long way in ensuring they feel heard and valued like anyone else in the workplace.

Sensitization of all major organization employees to foster a culture of acceptance and awareness, and an accessible work environment, is the need of the hour. Autistic individuals do well in a variety of job profiles, including IT, technology, finance, art and creativity, and administration.

Environmental modifications like background noise cancellation with headphones help those with sensory processing issues. At the end of the day, none of us is perfect, it's recognizing our special skills and strengthening them.

Possibilities are endless if we wish to encourage and make these individuals heard. So, let’s carry the Autism Awareness Day beyond a mere day of awareness and light it up blue. Let’s value and acknowledge them being different, but also empower them to act on their special skills to earn them a dignified place in society and the workplace.

World Autism Awareness Day is observed every year on April 2. The day is important to raise awareness about autism — a neurodevelopmental condition affecting communication, social interaction, and behavior — affecting millions of people globally.

According to the World Health Organization (WHO), one in 127 people worldwide is diagnosed with the lifelong brain health condition. It is also among the top 10 conditions contributing to health loss globally.

The first child diagnosed with autistic symptoms was Donald Grey Triplett. Labelled as Case 1, he went on to become an American banker, demonstrating that, if provided with the right and inclusive support and opportunities individuals with autism be as productive as others.

“Like anyone else, autistic people should be able to shape their own lives — and help to shape our shared future,” said

António Guterres, UN Secretary-General.

World Autism Awareness Day: Date and History

April 2 was designated as World Autism Awareness Day (WAAD) by the United Nations General Assembly in 2007.

The 2007 General Assembly resolution highlighted the need to raise public awareness of autism.

It stated that "children with disabilities should enjoy a full and decent life, in conditions which ensure dignity, promote self-reliance and facilitate the child’s active participation in the community, as well as the full enjoyment of all human rights and fundamental freedoms on an equal basis with other children".

World Autism Awareness Day: Theme

This year, World Autism Awareness Day is held under the theme "Autism and Humanity - Every Life Has Value".

The 2026 theme highlights and affirms the dignity and worth of all autistic people. While there are international human rights conventions safeguarding the rights of people with autism, they continue to face stigma, discrimination, and barriers to participation.

“Access to timely, quality health care and support services remains limited, driving inequalities across the life course," the WHO said. The global health body urged "sustained action and greater investment" to address these challenges. It also called for developing inclusive policies and services that uphold the rights of autistic people.

This year's theme, thus, is a call to action to recognize the inherent dignity and equal rights of all people with autism.

Guterres highlighted the need for "equal education, fair employment, and accessible health systems" for all persons with autism and to provide inclusive opportunities to participate and thrive, along with others.

What is Autism?

The National Health Service (NHS) UK defines autism as not an illness or a medical condition with treatments or a "cure", but a developmental condition that affects how people communicate, learn, behave, and interact with others.

It is a spectrum, which means "everybody with autism is different".

People with autism spectrum disorder (ASD) may have difficulty with social interaction, exhibit atypical behavior and activities, or find it hard to communicate.

Early Signs Of Autism

Studies show that symptoms of autism are usually diagnosed within the first 3 years of birth. These include:

• Limited to zero eye contact
• Delayed responses
• Repeating words or actions such as hand-flapping
• Being strong-headed about following the same routine
• Easily annoyed, throws tantrums
• Difficulty understanding and expressing emotions
• Sensitive to certain sounds, textures, lights, or smells.

The American Heart Association (AHA), in its latest update on nutrition guidance, has urged the need to eat a diet rich in vegetables and fruits, while also making a key shift to plant-based protein from meat-based protein earlier to improve heart health.

It has also emphasized the need to reduce the intake of sugar, salt and ultra-processed foods, as well as to switch to low-fat dairy.

The scientific statement, which is issued about every five years, comes amid increasing cases of high blood pressure and obesity in the US, which can potentially lead to poor health outcomes, including deaths from cardiovascular disease and other chronic conditions.

“For healthy eating to be more attainable and sustainable, we recommend people focus on their overall eating pattern rather than specific nutrients or foods. This approach is actionable, something that can be modified as people pass through different life stages, while still adhering to the nine key features,” said Alice H. Lichtenstein, volunteer chair of the scientific statement writing committee and senior scientist.

“The guidance applies to wherever you eat: at home, school, work, restaurants, or in your community. You want to strive for progress rather than perfection. Every time you choose to make a swap for a healthier alternative, you’re making a step toward a healthier life,” added Lichtenstein, who is also senior scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston.

The 9 Guidelines for a heart-healthy dietary pattern include:

• Maintaining a healthy body weight by balancing food intake and physical activity
• Eating plenty of vegetables and fruits
• Choose whole grains such as whole‑wheat bread, brown rice, and oatmeal over refined grains such as white bread or white rice
• Shifting from meat to plant-based sources such as legumes, including beans, peas, and lentils, along with nuts and seeds, and fish and seafood. Select low-fat or fat-free dairy products.
• Replace saturated fats with healthy unsaturated fats, including those from nuts, seeds, avocados, and non-tropical plant oils.
• Choose minimally processed foods instead of ultra-processed foods
• Limit beverages and foods with added sugars
• Choose foods low in sodium and prepare foods with minimal or no salt
• Limit intake of alcohol

Healthy Eating Patterns From Childhood

The 2026 guidance for children recommends a heart‑healthy dietary pattern starting at 1 year of age. It urges families to play a significant role and become role models.

“Cardiovascular disease begins early in life; even prenatal factors can contribute to increased risk in children as they grow. So, it’s important that healthy eating patterns are adopted in childhood and continue throughout the entire lifespan,” Lichtenstein said.

“The best way to do that is for adults to role model heart-healthy eating patterns inside and outside the home,” she added.
