Hospitals across Asia, Europe, and parts of North America are reporting a sharp rise in heat-related illnesses as global temperatures reach record highs this July. Health authorities are issuing urgent heatwave warnings and advising people, especially the elderly and children, to take precautions as climate change fuels more extreme weather events. According to the World Meteorological Organization (WMO), over 60 countries have recorded temperatures above 42°C (107.6°F) in the last two weeks — the highest since 2019. Cities like Delhi, Dhaka, Cairo, and Phoenix are seeing emergency rooms fill up with patients suffering from heatstroke, dehydration, and cardiovascular strain.
The elderly, people with chronic diseases, outdoor workers, and those without access to cooling are especially vulnerable.“We are seeing a rise in severe dehydration, kidney problems, and even deaths due to prolonged heat exposure,” said Dr. Tahmina Rahman, Head of Emergency Medicine at Dhaka Shishu Hospital. In Bangladesh, at least 32 people have died due to heat-related complications in the last month alone, and over 1,500 patients have been treated for heat exhaustion across government hospitals.
Countries are issuing heatwave alerts, distributing drinking water, and opening "cooling shelters" in public spaces. Bangladesh’s Ministry of Health has launched a hotline for emergency support and is advising schools to adjust class hours or shift to remote learning during extreme heat. “We are urging citizens to stay indoors during peak hours, wear light clothing, and stay hydrated,” said Dr. Abu Nasir, spokesperson for the DGHS. Experts say the current crisis is a warning of what’s to come if global warming is not addressed more aggressively. “Climate change isn’t just an environmental issue anymore — it’s a public health emergency,” warned Dr. Lin Zhang, a climate-health researcher at the University of Toronto. The UN Intergovernmental Panel on Climate Change (IPCC) predicts that by 2030, heatwaves could claim over 250,000 lives annually if current trends continue.

A major new international study has found a strong link between excessive screen time and mental health challenges in adolescents, including rising rates of insomnia, anxiety, and depression. The report, published by the Global Youth Wellness Foundation (GYWF), surveyed 72,000 teenagers aged 13 to 19 across 20 countries, including Bangladesh, the U.S., UK, and Japan. The study revealed that teenagers who spend more than 4 hours a day on social media or smartphones are twice as likely to report symptoms of poor sleep quality, mood swings, and lack of motivation. Digital Overload and the "Always-On" Culture "Teens today are exposed to a constant stream of notifications, comparisons, and content that overstimulates the brain," said Dr. Nafisa Chowdhury, lead researcher on the Bangladesh team. “It disrupts their sleep cycles, reduces face-to-face interactions, and fuels self-esteem issues.” Many teens reported checking their phones immediately before sleeping and even waking up at night to respond to messages or scroll through TikTok and Instagram. Mental Health Crisis in the Digital Age The study found: 34% of respondents reported signs of clinical depression 41% had trouble sleeping more than 3 nights a week 29% felt "chronically anxious" or socially disconnected Girls were more likely to report emotional distress linked to social media use In Dhaka, psychologists at private clinics say they’ve seen a threefold increase in teen patients over the past two years. What Experts Recommend Digital curfews: No screens 1 hour before bed App timers: Set daily limits for entertainment/social platforms Offline time: Encourage outdoor activities or family meals Mental health education: Include digital wellness in school curriculum Government Initiatives Underway In response to the growing concern, Bangladesh’s Ministry of Education is working with health officials to launch a "Safe Screens" campaign in schools, promoting healthy digital habits and offering workshops for both students and parents. “This is a national issue, and we must protect our next generation,” said Dr. Mostafa Kamal, advisor to the National Adolescent Health Program.
In recent years, Bangladesh has witnessed a concerning surge in lifestyle-related diseases such as diabetes, hypertension, heart disease, and obesity. Health experts and medical professionals are sounding the alarm as these non-communicable diseases (NCDs) are becoming increasingly common among people of all ages, especially in urban areas. The trend indicates a significant shift in the nation’s health landscape, which once was more focused on communicable diseases and infections. According to the Bangladesh Bureau of Statistics and several health studies, one in every three adults is at risk of developing high blood pressure, while diabetes is affecting both middle-aged and younger individuals at an alarming rate. Cardiovascular diseases are now one of the leading causes of premature death in the country. Doctors say this shift is largely driven by rapid urbanization, poor lifestyle choices, and lack of health education. The root causes of this growing health threat are deeply linked to changing lifestyles. Fast food consumption has increased dramatically in the past decade, especially among the youth. Fried items, sugary drinks, and processed snacks have replaced home-cooked meals for many people. At the same time, physical activity has decreased due to technology-driven work and entertainment habits. Office workers spend long hours sitting, children prefer mobile games over outdoor play, and people generally avoid walking even short distances. Stress is another major factor contributing to lifestyle diseases. Busy work schedules, financial pressure, and social expectations are leading to sleep disorders and mental health issues like anxiety and depression. Unfortunately, mental health remains a less talked-about topic in our society, leaving many people untreated and unaware of the connection between stress and physical illness. Doctors are urging people to adopt preventive measures rather than waiting for symptoms to appear. These measures include eating a healthy, balanced diet with more fruits, vegetables, and whole grains; drinking sufficient water; avoiding excessive sugar and salt; and engaging in regular physical activities such as walking, yoga, or exercise. Avoiding smoking and alcohol is also highly recommended. Health campaigns and educational programs are essential to raise awareness across all sections of society. Experts suggest that schools should introduce health and nutrition education from an early stage. Workplaces should encourage short breaks, offer healthy snacks, and promote mental wellness. Government healthcare centers can also play a key role by organizing regular health check-up camps and offering guidance on maintaining a healthy lifestyle. The government has taken some steps, including launching awareness drives and strengthening non-communicable disease units in hospitals. However, more action is needed to reach rural populations and lower-income groups who often have less access to healthcare and information. The rise of lifestyle diseases is not just a medical issue—it’s a social, economic, and national concern. If left unaddressed, it could burden families with high treatment costs, reduce workforce productivity, and increase pressure on the already strained healthcare system. Public health specialists are warning that Bangladesh could face a serious health crisis in the next two decades if preventive steps are not taken now. The message is clear: small daily changes like eating nutritious food, staying physically active, reducing screen time, and managing stress can have a huge impact on long-term health. Now is the time to act, before these silent diseases take a louder toll on our lives.
