Our brain is just like a muscle and it thrives on exercise. Moreover, it is the fastest-aging organ in the body. Studies show that brain volume naturally decreases with age due to neuronal loss, starting as early as your late 20s or 30s. This process accelerates over time, leading to a decline in cognitive functions such as memory, processing speed, and decision-making.

However, there is a way to counter it. Neurologists across the world agree that frequently playing brain games can prevent brain ageing. Backing them up is research showing that brain-training games may help improve attention levels, memory, response time, logic skills, and other measures of cognitive function if played over a long period.

And the good news is that these brain games are affordable and easily accessible to all. you just need a pen and paper for sudoku and the same goes on for crosswords. However, if you are someone who is up for a high-tech, options for brain games are plentiful.

Dengue has become one of the fastest-emerging health crises in the urban parts of India. Every year during the monsoon season, the number of dengue cases rises dramatically in many Indian cities, posing a huge burden on the healthcare sector.

Though climate and mosquitoes are usually cited as reasons for the surge in dengue cases, the problem actually lies in how urban life and the infrastructure of the cities have changed over the decades.

Why Urban Areas Are More Vulnerable

The dengue virus is spread through the Aedes aegypti mosquito that lives well in fresh still water, which is abundant in urban areas.

Mosquitoes breed in construction sites, open water tanks, old plastic buckets, flower pots, coolers, water stored on roofs, and blocked drainage systems. Due to the growing size of cities and high population density, mosquito-borne diseases have become more common.

There are many factors that contribute to the rise in the number of dengue patients, one of which is unplanned city expansion. The fast pace of development in the cities results in stagnant water in the construction areas going unnoticed for weeks.

Moreover, improper drainage and a lack of sanitation facilities help mosquitoes breed. Even posh societies and offices can suffer if proper checks are not conducted.

Urban lifestyle trends also act as indirect factors contributing to the issue. Longer working hours, higher levels of indoor activities, and reliance on mechanical ventilation lead to less focus on environmental hygiene issues.

Families tend to take mosquito prevention steps only after an outbreak starts. The overuse of plastics and poor waste management practices in urban areas have exacerbated waterlogging problems.

The situation has been exacerbated by climate change and global warming. Mosquitoes can breed at a faster pace and survive for a longer period of time in the warm climate and unpredictable rain patterns. Another factor that plays an important role is urban heat islands, which refer to places that are hotter because of man-made concrete buildings.

What Needs to Change?

In order to curb the incidence of dengue, there must be an all-around transformation, both on the part of the governing authorities and the people. Firstly, urban planning should take into consideration good drainage facilities, frequent fogging, garbage disposal services, and proper regulation of building sites. Secondly, there must be frequent checks in residential areas, schools, offices, markets, and open public areas.

Secondly, the awareness campaign needs to be practical and more community-oriented. The citizens should realize that the prevention of dengue starts from their homes. Actions like washing the coolers once a week, covering the water tank, not allowing the water to stagnate, and using mosquito repellents will go a long way in minimizing the spread of dengue.

Early Detection and Healthcare Preparedness

Healthcare preparedness is also equally important. The early detection and proper treatment of dengue could help avoid any serious complications. One should never overlook symptoms like fever, body pain, headache, rashes on the skin, nausea, and weakness during the rainy season.

Combatting dengue fever is no longer just a matter of health care but rather a question of urban planning and lifestyle issues. As the cities continue to expand, everyone should unite and come up with healthier and more environmentally friendly cities. Otherwise, we may see more recurring problems of dengue outbreaks in urban settings every year.

India has recorded 6,927 dengue cases and 10 deaths so far in 2026, according to the latest data from the National Centre for Vector Borne Diseases Control (NCVBDC).

According to the provisional data as of February this year, Tamil Nadu reported the highest number of cases at 2,873, followed by Maharashtra with 786, Kerala with 670, Karnataka with 560, and Andhra Pradesh with 448 cases. During the same period, Kerala reported nine deaths, while Tamil Nadu reported one death.

According to the Ministry of Health, the Case Fatality Rate (deaths per 100 cases) for dengue has remained below 1 per cent since 2008 and stood at 0.13 per cent in 2024.

The dengue burden in India has steadily increased over the past few years:

National Dengue Day: History And Theme

Launched in 2010, National Dengue Day is observed every year on May 16 as a pre-monsoon alert to help communities prepare before mosquito breeding peaks.

“On National Dengue Day, let us unite to spread awareness about dengue prevention and keep our surroundings clean and safe. The Government of India continues to strengthen dengue control through better surveillance, testing, improved treatment, and awareness campaigns,” said Jagat Prakash Nadda on the social media platform X.

“This year’s theme, ‘Community Participation for Dengue Control: Check, Clean and Cover,’ reminds us that community action is key to defeating dengue,” he added.

Dengue Vaccines In India

Notably, India is currently developing an indigenous dengue vaccine that is undergoing clinical trials.

“The trials will take at least two and a half years, which means by the end of 2028, we will have the results,” said Dr. N K Arora, Member of the National Technical Advisory Group on Immunization in India (NTAGI), speaking to HealthandMe.

He highlighted the severity of dengue when it progresses from a mild illness to a severe one, particularly among young adults.

The vaccine is expected to play a crucial role in protecting the 10–20 age group, which is considered more susceptible to severe dengue cases.

“We are waiting for the results of the trials, and once the vaccine is recommended by the NTAGI, the system will be ready to adopt it,” Dr. Arora added.

Meanwhile, Qdenga, a dengue vaccine developed by the Japanese pharmaceutical company named Takeda Pharma, is expected to be rolled out soon in the country.

The vaccine TAK-003 will be available in India through a manufacturing partnership with Hyderabad-based Biological E (Bio E), in line with the 'Make in India' initiative.

What Is Dengue?

Dengue is a viral infection transmitted primarily by Aedes mosquitoes and is common in tropical and subtropical regions worldwide.

Mild dengue causes high fever and flu-like symptoms. However, in some cases, it can progress to severe dengue, also known as dengue hemorrhagic fever, which may lead to serious bleeding, shock, and death.

Dengue is considered the most prevalent viral infection transmitted by Aedes mosquitoes. More than 3.9 billion people across over 132 countries are at risk, with an estimated 96 million symptomatic cases and around 40,000 deaths annually worldwide.

Symptoms Of Dengue Fever

Symptoms usually appear 4–10 days after being bitten by an infected mosquito and may vary in severity. Common symptoms include:

• High fever
• Severe headache
• Pain behind the eyes
• Joint and muscle pain
• Nausea and vomiting
• Fatigue
• Skin rashes appearing a few days after fever onset

In severe cases, dengue may cause excessive bleeding, a sudden drop in blood pressure, and organ complications.

How To Prevent Dengue

Preventing dengue mainly involves reducing mosquito exposure and eliminating mosquito breeding sites. Effective preventive measures include:

• Using insect repellents containing DEET
• Wearing long-sleeved clothing, especially during dawn and dusk
• Installing screens on windows and doors
• Using mosquito nets while sleeping in endemic areas
• Eliminating stagnant water in flower pots, gutters, and containers
• Using mosquito traps or insecticide-treated materials in mosquito-prone areas.

While alcohol consumption is known to be harmful to health, a new study has linked it to 62 disorders ranging from heart and digestive diseases to mental and neurological conditions and cancers.

The study, published in the journal Addiction, showed that the fully alcohol-attributable conditions are mainly grouped under non-communicable diseases and injuries. These include endocrine, nutritional, and metabolic diseases, mental and behavioral disorders, diseases of the nervous system, diseases of the circulatory system, such as alcoholic cardiomyopathy, and digestive diseases, including alcoholic liver disease and cirrhosis.

The latest data also adds psychotic disorders, gastritis, ulcers, pancreatitis, fatty liver disease, pregnancy- and perinatal-related conditions such as fetal alcohol syndrome and fetal alcohol spectrum disorders, as well as external causes and injuries, including alcohol poisoning.

“These conditions are 100 per cent alcohol attributable, meaning these diseases would not even exist in the world without alcohol use,” said Jürgen Rehm, senior scientist at the Institute for Mental Health Policy Research in Toronto and part of the study team, according to CNN.

“There are another 30 diseases in which alcohol plays a role, such as breast and other cancers, heart disease, stroke, diabetes, and dementia,” Rehm said. “These diseases would exist even without alcohol use, but alcohol use is responsible for a certain proportion of them.”

How The Study Identified Alcohol-Related Diseases

The diseases and injury categories fully attributable to alcohol were identified using the World Health Organization (WHO) International Statistical Classification of Diseases and Related Health Problems, 10th (ICD-10) and 11th (ICD-11) revision databases.

The study defines heavy drinking as more than 40 g of pure alcohol a day for women and 60 g a day for men. This translates to about 1.4 ounces of liquor for women and 2.1 ounces for men.

The good news, researchers said, is that many of these health effects can be slowed, stopped, or even reversed.

“Fortunately, the immediate effects of alcohol on the immune system don’t last long. Depending on levels of consumption, the body bounces back within days to a week,” Rehm said.

Alcohol And Cancer Risk

In 2025, former US Surgeon General Dr. Vivek Murthy released a new Surgeon General Advisory on alcohol and cancer risk, highlighting the direct link between alcohol consumption and increased cancer risk.

Similar to warning labels on cigarettes, the Surgeon General called for cancer risk warnings on alcohol products.

The report released by the US Surgeon General’s office identified at least seven types of cancer associated with alcohol consumption. It also recommended updating alcohol labels to include cancer warnings and reassessing guideline limits for alcohol consumption.

The cancers linked to alcohol consumption that Murthy recommended should be included on warning labels:

• Breast cancer
• Colon cancer
• Throat cancer
• Liver cancer
• Voice box cancer
• Esophageal cancer
• Mouth cancer.
