The heat waves are rising all over the world and causing a lot of damage. While there are issues of dehydration and heat strokes, studies are suggesting that it might also be responsible for declining mental health, the heat among other things is not only affecting the physicality of human beings but is also having adverse mental health.

Emotional distress: The heat can trigger mood swings, making you feel irritable, anxious, depressed, or even aggressive. You may not be able to predict your reaction, you may be good one moment and then any minor inconvenience will make you angry or sad. Heat often triggers that helplessness in people.

Scattered Focus: Concentrating on tasks becomes a struggle when it's hot. Simple things feel overwhelming, and staying focused is a challenge. While you may be in the zone working on completing something, the heat and sweating will disrupt your flow and then you will not be able to focus on anything other than the heat.

Sleepless Nights: High temperatures, especially at night, disrupt your sleep. This lack of rest can leave you feeling tired, and grumpy, and worsen existing mental health issues. All humans require a comfortable temperature to sleep in, if your body is too wound up or heated up, it will not be able to relax and sleep.

Feeling the Pressure: The heat can pile on stress and make you feel overwhelmed. Concerns about the heat itself or its impact on other aspects of your life can contribute to this feeling. You will feel overwhelmed and unable to work on anything else. The heat makes you feel a certain helplessness, as you cannot stop the sun or turn down the heat.

Body Blues: The heat can cause physical symptoms that affect your mental well-being. Headaches, fatigue, dizziness, and nausea can all contribute to anxiety and low mood. When your body is already fatigued, the urge to do anything else disappears. Your body is drained of energy to function at all and will seek rest and sleep.

Behavioural Shifts: The heat can influence your behaviour. You might act impulsively or have difficulty managing anger. It's like the heat turns up your emotional thermostat. When your body and brain are overheating, it is difficult to think straight and you will grasp at straws to release this energy and pressure off of you.

Some other side effects of the heat are.

• Mental Health Flare-Ups: If you already have a mental health condition, hot weather can worsen your symptoms. Existing depression, anxiety, bipolar disorder, or schizophrenia might feel more intense.
• Heat and Suicide Risk: Studies show a disturbing link between hot weather and increased suicide rates, particularly among men and older adults. Hot weather can be a tipping point for those already struggling.
• Heatwave Hospitalizations: When temperatures soar, people with existing mental health issues may require increased hospitalization. This highlights the need for healthcare systems to be prepared for heat waves.
• Climate Change and Mental Health: Climate change is leading to more frequent heatwaves. Research suggests this could lead to a rise in mental health problems and suicides. Taking action against climate change is crucial for protecting mental well-being.

Breastfeeding is important not only for babies' health and nutrition but also for protecting mothers from serious diseases, the World Health Organization (WHO) said.

It urged governments to strengthen access to services and interventions that support breastfeeding as part of World Breastfeeding Week, observed annually from August 1–7.

The 2026 theme, "Breastfeeding for a Sustainable Start in Life: Strengthen What Works," focuses on tracking progress, evaluating impact, and scaling proven approaches that improve breastfeeding outcomes.

Breastfeeding Could Save Hundreds of Thousands of Lives

"Scaling up breastfeeding could prevent almost 400,000 child deaths and around 140,000 maternal deaths each year," said UNICEF Executive Director Catherine Russell and WHO Director-General Dr. Tedros Adhanom Ghebreyesus in a joint statement.

"Every US$1 invested in breastfeeding promotion generates an estimated US$59 in economic returns through lower health-care costs, improved cognitive development, higher educational attainment, and increased lifetime earnings," they added.

Health Benefits for Babies and Mothers

The experts noted that breastfeeding is one of the simplest and most powerful ways to protect a child's health. It provides infants and young children with essential nutrition, boosts immunity, helps protect against serious illnesses, and supports cognitive development.

For mothers, breastfeeding also offers significant health benefits by reducing the risk of noncommunicable diseases such as breast and ovarian cancers, and type 2 diabetes.

Global Breastfeeding Rates Have Improved

The WHO said breastfeeding rates have improved globally due to sustained investments in policies and programs supporting mothers and families.

Exclusive breastfeeding during the first six months increased from around 37 per cent in 2012 to more than 47 per cent today. Over the past five years, the prevalence of breastfeeding up to two years of age has risen from 38 per cent to 50 per cent.

Progress Remains Uneven

Despite these gains, the WHO said many countries continue to lag behind global targets.

"Coverage of services supporting breastfeeding remains low, policies are inconsistently enforced, and service quality is often inadequate, especially in low-income, fragile, and humanitarian settings," the WHO said.

The agency noted that cost-effective interventions include skilled breastfeeding support within health systems, community-based counselling, maternity protection policies, and protection from the exploitative marketing of commercial milk formulas.

WHO, UNICEF Call for Stronger Support

WHO and UNICEF called on governments, health systems, workplaces, communities, civil society organizations, and families to strengthen the "Warm Chain of Support" for breastfeeding.

During World Breastfeeding Week, the agencies urged countries to:

• Strengthen health systems to provide quality breastfeeding support for mothers and newborns.
• Expand community-based counselling and peer support programs.
• Fully implement and enforce the International Code of Marketing of Breast-milk Substitutes.
• Invest in paid maternity leave and supportive workplace policies.
• Integrate breastfeeding interventions into antenatal, perinatal, and postnatal health-care services.
• Sustain breastfeeding support in humanitarian and fragile settings.

"Breastfeeding is vital. By investing in proven solutions, we can give every child the best possible start in life and ensure every mother gets the care and services she needs," the agencies said.

A new study published in The Lancet Regional Health–Southeast Asia has found that India accounts for 68% of all childhood cancer cases in the SAARC region.

While the country's large child population contributes to the high numbers, experts say underdiagnosis and incomplete cancer registration may mean the actual burden is even greater.

An international team of researchers, including from the US, India, and Canada, estimated that nearly 37,700 children aged up to 14 years were diagnosed with cancer across South Asia in 2022, with 17,700 deaths reported. India alone accounted for an estimated 25,939 cases and 12,028 deaths.

The researchers noted that because cancer registration remains incomplete, particularly in rural areas, the true number of childhood cancer cases in India could exceed 50,000 annually.

India's Large Child Population Drives Numbers

India is home to more than 380 million children, accounting for nearly 69% of the child population in the SAARC region. This naturally contributes to the country's higher share of childhood cancer cases and deaths.

However, experts emphasize that population size is only part of the explanation. Delayed diagnosis, limited access to specialized treatment, and gaps in cancer registration continue to affect both disease estimates and patient outcomes.

Leukemia Most Common Cancer

Dr. Narendra Agrawal, a leading Hematologist and Bone Marrow Transplant Physician and Senior Consultant and Unit Head of Haemato-Oncology at Rajiv Gandhi Cancer Institute & Research Centre, told HealthandMe that childhood cancer remains a major public health concern in India.

"Current estimates suggest that around 70,000–80,000 children and adolescents develop cancer each year, although the exact number remains uncertain due to expanding cancer registration systems". The most common childhood cancers in India include:

• Leukemia
• Lymphomas
• Brain tumors
• Bone tumors

What Causes Childhood Cancer?

Unlike many adult cancers, most childhood cancers do not have a clearly identifiable or preventable cause. Dr. Agrawal explained that, in most children, cancer develops because of genetic changes that occur during early development. These changes are usually not linked to lifestyle factors or inherited from parents.

Recognized Risk Factors

Although the causes of most childhood cancers remain unclear, some well-established risk factors include:

• Ionizing radiation: High-dose exposure before birth or during childhood increases the risk of leukemia and certain other cancers.
• Genetic syndromes: Conditions such as Down syndrome, Li-Fraumeni syndrome, and neurofibromatosis increase susceptibility to specific childhood cancers.
• Certain infections: Epstein–Barr virus (EBV) is associated with some lymphomas, HIV increases lymphoma risk, and chronic hepatitis B infection raises the risk of liver cancer.
• Environmental and parental exposures: Tobacco smoke, certain chemicals, pesticides, and some occupational exposures have been investigated as possible risk factors, although evidence remains inconclusive.

Challenges Beyond Disease Burden

Dr. Agrawal said India's substantial childhood cancer burden is largely driven by its population size. However, improving outcomes requires addressing several systemic challenges.

Key issues include:

• Delayed diagnosis
• Limited access to specialized pediatric oncology services in some regions
• Treatment abandonment
• Incomplete cancer registration

For many people, the first thing that comes to their minds when hearing the term “lung cancer” is smoking. Although smoking remains the primary causative factor for this cancer, many other risk factors have been identified that need to be considered.

Lung cancers develop in non-smokers too and form a rather large percentage of all cases. Thus, it is very important to enlighten people about other possible causes of lung cancer.

Hidden Risk Factors That Deserve Attention

Second-hand smoking is one of the major risk factors that leads to the development of lung cancer in non-smokers. Exposing oneself to a smoker in your family, workplace, and in your surroundings for a prolonged period of time can result in accumulation of smoke and carcinogens found in cigarette smoke even in a non smoker’s lung.

The other reason for the development of the disease is air pollution which is critically worsening by the day, especially in large cities where the proportion of particulate matter is rising in the air.

Chemical exposure at workplace to harmful substances and carcinogens such as asbestos, silica dust, diesel exhaust, arsenic, and other industrial chemicals also increase the risk. Using protective wear at work is essential in industries dealing with such chemicals is very essential.

The presence of radon gas in some geographical locations is another lesser known cause. Invisible and odorless in nature, exposure to high levels of radon gas has been known to cause lung cancer.

Family History and Personal Health Matter.

People with a family history of lung cancer in their immediate family could be more prone to developing lung cancer, even without having ever smoked. The factors contributing to this are not hereditary or genetic as directly as other cancers, but more as a result of shared environmental exposure and lifestyle factors.

Certain lung conditions, such as COPD, pulmonary fibrosis, and some long-standing lung infections, can also increase the risk.

Age is another important factor. Lung cancer is more commonly diagnosed in older adults, but it can also occur in younger people. That is why it is important to be aware of the symptoms and seek medical attention early, regardless of age.

Recognising the Warning Signs Early

The main problem in diagnosing lung cancer is that this disease has no symptoms until it develops to a certain extent and has symptoms such as coughing persistently, coughing up blood, chest pain, unexplained weight loss, shortness of breath, chest infection, and exhaustion.

None of these symptoms can be ignored as lung cancer can still be treated in its early stages.

Awareness Can Save Lives

Preventing lung cancer entails more than just not smoking. Measures to ensure good air quality at home, to protect against any occupational dangers and hazards, to reduce exposure to air pollutants whenever possible, and to undertake regular health examinations can help in prevention and early detection.

Just as crucial is the awareness of symptoms and the fact that anyone can get lung cancer, including people who have never smoked.
