How childhood stress can undermine memory skills
Experts say that children are more stressed than adults. This is due to constantly having to face new and confusing situations. Researchers have found that childhood stress can affect memory skill of students.
Many children today transition from playfulness and innocence to mental stress and other worries during adolescence. It is crucial to understand children’s issues and actively seek solutions rather than fretting over them. These challenges during a critical stage of development can significantly impact children’s memory and intelligence.
A world full of happiness and no worries… Such is the view of parents and guardians about the world of children. They don’t have to worry about work to be done or responsibilities, so what’s the stress on them? But the data coming out about children’s mental health suggests that these are all just our misconceptions.
The number of children seeking counseling and mental health treatment is increasing day by day. To those who wonder what tension they have for this alone, they say, many. At a very young age, children experience minor stress or mental tension!
What is stress?
What is stress if it affects even children? Stress is the body’s coping mechanism to deal with and adapt to challenging situations. A balance of demands from multiple sources or the ability to meet them leads to stress. Such demands may come from family, work, school, or friends, and sometimes one’s own demands can also lead to stress. Stress occurs when the demand and the ability to meet it do not match.
Dr Rashmi Prakash, a member of the Australian Psychological Society, says that a small amount of stress is beneficial to children. But stress can have long-term effects on children if it goes too far
Stress occurs in children for many reasons. The worry of missing parents at a very young age, academic issues later in life, social pressures, mental and physical abuse, problems between parents and isolation all contribute to stress in children. Dr Rashmi Prakash, a member of the Australian Psychological Society, says that a small amount of stress is beneficial to children. But stress can have long-term effects on children if it goes too far. Recently Indian researchers have found that childhood stress can affect memory skill of students.
Research conducted by a team consisting of Radha Raghuraman, Anoop Manakadan, Gal Richer Levin, and Sreedharan Sajikumar, in 2022, found that childhood stress can have a detrimental effect on memory.
How to spot stress in children
Stress and related problems in children can be difficult to identify, but sudden anger, mood swings, misbehaviour, changes in sleep patterns, and bedwetting can all be considered signs of stress. Some may also experience physical effects due to stress. For example, stomach ache and headache. Others have symptoms such as lack of concentration and inability to complete studies. Apart from this, being away from everyone and spending a lot of time alone is a sign of stress. Signs of stress include thumb-slapping, hair-twisting, nose-picking in young children, and lying, bullying, and backbiting in adults. Stressed out children can get into big fights even over small things. Falling behind in studies is also a symptom of stress.
The connection between stress and memory
Experts say that children are more stressed than adults. This is due to constantly having to face new and confusing situations. Children are greatly influenced by the expectations placed on them by the adults around them, especially parents and teachers. Children often judge themselves by those expectations. When those expectations are not met or when their skills, abilities, and pride are called into question, they are unable to cope.
Separation from parents especially mother, physical or mental abuse, fear etc. can lead children of any age to stress
Recent studies have shown that stress levels in children have been on the rise over the past few decades. Radha Raghuraman says that exposure to stress during childhood can affect the ability to connect different types of memories as adults. The research team conducted studies on this in mice. As the juvenile phase in mice is equivalent to the adolescent phase in humans, adolescent stress is the main concern here. Radha explains that since the structures of the memory-related brain regions of mice and humans are almost identical, their findings may hold true for humans as well.
Separation from parents especially mother, physical or mental abuse, fear etc. can lead children of any age to stress. Depending on the age at which stress occurs, how long it has lasted, the intensity, and the type of stress, the changes it causes in the body and behaviour will vary.
Adolescent stress stimulates certain epigenetic factors. Like a gene, a piece of DNA that carries information necessary for specific functions in a cell, an epi-gene is a factor that causes a gene to decide whether or not to express the information in the gene, and if so, how much to express.
Parental proximity also plays a major role in reducing stress in adolescents. Even after work, you should be interested in sitting with the children and asking about their affairs.
Through their study, Radha and his team found that stress during adolescence results in increased activation of the epi-gene G9a/GLP. It affects the formation of certain proteins that stabilise newly formed memories. As a result, memories that have already been formed are perfected and as they grow, there is no room for other memories that come in connection with them. Associative memory is the ability to connect existing memories with recent or recent events and find similarities and dissimilarities between them. Adolescent stress mainly affects associative memory. Radha says that G9a/GLP was found to be significantly higher in stressed mice. The researchers also found that associative memory was restored when G9a/GLP was blocked with the drug.
How to save children from stress
Adequate rest, nutritious food, closeness, attention and care of parents can give children a lot of relief from stress. Parents should try to be with their children when they want. If you notice that there are any problems, talk to them openly instead of thinking that they will tell you here.
Parental proximity also plays a major role in reducing stress in adolescents. Even after work, you should be interested in sitting with the children and asking about their affairs.
Studies remind us that stress during adolescence should be viewed more cautiously than stress at any other time. Adolescence is also a period of growth in children. Facing stress at a time when the development of many important organs including the brain is not complete can lead to many types of consequences while growing up.

A Green Future in the Making: India’s Renewable Energy Surge
With wind, solar, hydro, and bioenergy resources contributing to this capacity, India is moving steadily toward its goal of energy independence and environmental sustainability
The coastal winds of Tamil Nadu swept across the lush green fields, carrying with them the promise of a cleaner, more sustainable future. As the sun dipped below the horizon, the turbines that dotted the landscape turned steadily in the breeze, their blades slicing through the air like symbols of progress. In this southern state, a renewable energy revolution was taking root—one that would power not only the homes of millions but potentially reshape the future of global energy.
This transformation is not just a story of Tamil Nadu; it is the story of India, a nation rapidly advancing toward its renewable energy goals, with states like Rajasthan, Gujarat, Tamil Nadu and Karnataka playing a pivotal role in that progress. In October 2024, India’s renewable energy capacity soared past the 200-gigawatt (GW) mark, solidifying the country’s position as a global leader in clean energy. This milestone marks a critical point in India’s journey, as it works toward its ambitious target of 500 GW of renewable energy capacity from non-fossil sources by 2030.
As of 2024, Tamil Nadu boasts a renewable energy capacity of 23.7 GW, much of it derived from its wind farms. These wind corridors, stretching across the coastal plains, are among the most productive in the world. The state is also a major player in solar energy, leveraging its abundant sunlight to complement its wind resources and create a well-rounded renewable energy mix.
Tamil Nadu’s approach to renewable energy reflects a larger national trend. India, with its vast land, diverse climates, and abundant natural resources, is uniquely positioned to lead the global renewable energy revolution. The country’s total renewable energy capacity has surged by 24.2 GW in just a year, reaching 203.18 GW by October 2024. With wind, solar, hydro, and bioenergy resources contributing to this capacity, India is moving steadily toward its goal of energy independence and environmental sustainability.
Harnessing the Winds of Change
From sprawling solar farms in Rajasthan to the wind farms off Tamil Nadu’s coast, India has carefully cultivated a diverse renewable energy portfolio. The surge in renewable capacity includes an impressive 92.12 GW of solar power, 47.72 GW of wind energy, and 46.93 GW of hydroelectric power. With the addition of bioenergy resources, including biomass and biogas, which contribute 11.32 GW, India’s renewable energy landscape is not just growing—it’s evolving into a robust, multifaceted powerhouse.
The International Renewable Energy Agency (IRENA) reported that India accounted for a substantial portion of the 16.2 million jobs in the global renewable energy workforce.
This progress is not just about reducing India’s reliance on fossil fuels—it’s about securing the country’s energy future. In 2024, non-fossil sources, including nuclear power, now account for nearly half of the total installed electricity generation capacity, a figure that marks an essential step in India’s journey toward energy security and global environmental leadership.
The Winds of Change: How Renewable Energy is Powering Job Creation
But India’s renewable energy revolution isn’t just about the environment—it’s also driving economic growth. In 2023, the sector created over 1 million jobs, with hydropower and solar power leading the way in employment opportunities. The International Renewable Energy Agency (IRENA) reported that India accounted for a substantial portion of the 16.2 million jobs in the global renewable energy workforce. In particular, hydropower alone provided over 450,000 jobs, while solar energy employed approximately 318,600 people, a number that continues to grow.
As India’s renewable energy sector expands, so too does the potential for more green jobs. From construction and installation to operations and maintenance, the job opportunities created in this sector are helping to power not just the economy, but the livelihoods of millions of people across the country.
Leading the Charge: India’s Global Climate Commitment
India’s renewable energy achievements are a testament to its unwavering commitment to addressing the global climate crisis. Under the Paris Agreement, India has made bold promises to reduce its emissions and transition toward a low-carbon economy. By 2030, the country has committed to cutting its emissions intensity by 45% compared to 2005 levels, and to sourcing 50% of its cumulative power capacity from non-fossil sources.
These targets align with India’s long-term strategy to reach net-zero emissions by 2070. The nation’s efforts are rooted in the principle of equity, recognizing that the fight against climate change must account for the differing capabilities and responsibilities of countries around the world.
India is not just a participant in the global effort to fight climate change—it is emerging as a leader. The country’s growing renewable energy sector is proving that it’s possible to combat climate change, secure energy independence, and create millions of green jobs in the process.
India’s Renewable Leaders
While India’s renewable energy revolution is a national effort, certain states have emerged as leaders in driving the country’s green energy push. Rajasthan, with its vast land and abundant sunlight, leads the way with 29.98 GW of installed renewable capacity. Gujarat follows closely with 29.52 GW, bolstered by the state’s aggressive solar and wind energy policies. Tamil Nadu, with its coastal wind corridors, contributes 23.7 GW, while Karnataka rounds out the top four with 22.37 GW.
These states are not just providing energy—they are setting the stage for India’s renewable energy future, serving as models for other regions to follow.
The Road Ahead: A Green Energy Future
As India celebrates the achievement of over 200 GW in renewable energy capacity, the country stands at the threshold of even greater accomplishments. With its eyes set firmly on the target of 500 GW by 2030, India is positioning itself not only as a leader in renewable energy but also as a key player in the global fight against climate change.
Government initiatives such as the National Green Hydrogen Mission, the PM-KUSUM(Prime Minister’s Scheme for Farmers’ Energy Security and Upliftment )scheme, and the Production-Linked Incentive (PLI) program for solar photovoltaic modules are all part of India’s broader strategy to enhance its renewable energy capacity and reduce its dependence on fossil fuels.
India’s renewable energy journey is far from over—but the path ahead is clear. By continuing to invest in solar, wind, hydro, and bioenergy, India is not just meeting its energy needs; it is setting an example for the rest of the world to follow.
In the fight against climate change, every gigawatt matters. And India is proving that, when it comes to renewable energy, the world can count on it to deliver.

How the Same Customer Can Bring You More Revenue
You walk into a car showroom, intending to buy the base model of a car, considering your budget constraints. The sales executive shows you the car, explaining its features in detail. He then suggests, “Sir, why don’t we also check out the next variant?” Intrigued, you follow him to the upgraded model and listen as he elaborates on its extra features. You find it much better than the car you initially intended to buy, and eventually, you decide to purchase the higher variant.
The strategy employed by the sales executive here is known as “upselling.” He successfully persuaded you to spend more money on a more expensive model than you originally planned. This is similar to a customer intending to buy an Apple iPhone 16 but ending up purchasing the Apple iPhone 16 Pro Max instead. Or when you walk into a pizzeria intending to have a small pizza but end up ordering a medium or large one due to the server’s convincing pitch. These are all outcomes of effective upselling.
Now, let’s look at another scenario. You enter a restaurant and order a masala dosa, a popular South Indian dish. When the waiter serves your dosa, he also places a vada (a savoury, deep-fried snack commonly found in South Indian cuisine) on the plate. Hungry, you eat both the dosa and the vada, pay the bill, and leave. Though you could have simply eaten the dosa, the restaurant managed to sell you an additional product.
This technique is known as “cross-selling.” The restaurant sold you a vada alongside the dosa you initially ordered. Similarly, when you order a product from Amazon, you often see a message like, “Customers who bought this also showed interest in these products,” accompanied by pictures of related items. Amazon is effectively cross-selling to you.
Both upselling and cross-selling can be applied in any business. Employees should be trained in these strategies, and attractive offers and discounts should be provided to customers
These are two effective strategies in sales. A retailer can sell a bedroom set to a customer who came to buy a cot or mobile phone accessories to someone purchasing a phone. Similarly, a tile showroom selling sanitary products, hardware, and electric fittings follows the same principle. The goal is to get the same customer to buy more products and thus increase sales.
Both upselling and cross-selling can be applied in any business. Employees should be trained in these strategies, and attractive offers and discounts should be provided to customers. For example, offering three t-shirts in different colours for $18 instead of one for $7.20 is likely to attract more buyers. Let’s start implementing these tactics to boost our sales.
