What is Depression?
The word ‘depression’ means downward. When it comes to interpreting it medically or psychologically, depression refers to a mental disorder. Depression or depressive disorder causes loss of pleasure or interest in activities for a longer period of time.
It is different from what we know as regular mood swings or feeling ‘off’ because depression is a persistent and intense condition that significantly impacts daily life, whereas mood swings are typically temporary, less severe, and often linked to external triggers or stressors. Depression can negatively affect how you feel, think, act, and perceive the world.
Depression Statistics Around the World & India
- It has been estimated that around 5% of the world population is depressed, which translates to about 300 million people.
- The cases of depression have surged by 60% between 1990 and 2019. There has been growing concern over the rise of depression in India also, especially among teenagers, young adults, and women.
- Recent studies show a rising trend of depression among young people in India, with prevalence rates ranging from 31% to 57%.
- UNICEF also reports that 1 in 7 individuals aged 15 to 24 in India constantly feels depressed or lacks interest in activities.
- This highlights a concerning prevalence of mental health issues in this age group, which could have serious long-term effects on their well-being and overall quality of life.
Causes of Depression & Its Risk Factors
- Social media addiction can lead to alteration of the brain’s physiology as it can rewire its functioning.
- It occurs in the ‘reward system’ areas like the ventral tegmental area, nucleus accumbens, and prefrontal cortex.
- When we are engaged in social media or other types of pleasurable activities, these areas release dopamine.
- Dopamine is a neurotransmitter that makes us feel good in the way that we have received some kind of reward.
- Dopamine is a “feel-good chemical”.
- This is just like taking drugs or alcohol, which can cause an intense spike in dopamine levels.
- This leads to a strong sense of euphoria and a ‘desire’ to undergo that kind of activity again to stay high.
- Without the ‘substance’ (social media in this case), the brain struggles to find balance or pleasure, which causes anxiety, mood swings, and other symptoms.
- In this way, people can become social media addicts.
- The other common signs of social media addiction include neglecting responsibilities, preoccupation with thoughts about online friends, loss of interest in other activities, and withdrawal symptoms.
Biological Causes
Genetic Factors
It has been estimated that depression is a genetic disorder that runs through generations in a family since genetics play a major role in 40% of cases.
It is interesting to know that although many people may inherit genes that transfer depression genetically, they may never suffer a depressive illness.
Lack of Neurotransmitters or Brain Chemicals
Our brain cells interact with each other through chemical messengers, known as brain chemicals or neurotransmitters, namely dopamine and serotonin.
They are the chemicals that make us feel good, motivated, and enthusiastic in our day-to-day life.
The reduced activity of one or more of these neurotransmitter systems may disturb the brain that regulates its function.
The reduced level of these brain chemicals can inhibit the communication between nerve cells and accounts for depression.
Some of the prime reasons that affect the neurotransmitter system are:
- Poor diet
- Exposure to toxins such as alcohol
- Smoking
- Prolonged stress
- Lack of enzyme activity that maintains the level of dopamine and serotonin
Hormonal Factors
Teenagers between the ages of 13 and 19 are particularly vulnerable to depression because their bodies undergo significant physical, emotional, and hormonal changes during this period.
Depending on the age and gender, the levels of different hormones such as thyroid hormone (T3 and T4), estrogens, serotonin, etc., can affect the mood and contribute to episodes of depression.
It is important for parents and teachers to pay close attention to individuals exhibiting symptoms such as anxiety, mood swings, irritability, and lack of motivation.
Providing proper care to teenagers and, if necessary, seeking professional help can significantly reduce the risk of these individuals falling into depression.
Emotional Causes
- Loss of loved ones at an early age or physical separation from them for a longer period of time.
- Abuse or neglect from people.
- Ongoing stress from work, relationships, or financial issues.
- Negative self-perception or feelings of worthlessness.
- Lack of social support and feelings of loneliness.
Social Causes
Fear of Missing Out or FOMO is the leading cause of depression in Gen Z people. FOMO refers to the anxiety of missing out on exciting or interesting events that provide rewarding experiences and that others might be receiving. It causes social comparison with others, frequent phone use, anxiety, poor sleep patterns, higher stress levels, behavioral changes, etc.
Role of Technology in Causing Depression
From early mornings to late nights, we are constantly surrounded by tech gadgets and applications which are making our life easier in every aspect. However, they are equally responsible for causing mental health issues in people, especially in teens and young adults.
Addiction to Social Media
Social media is one of the major causes of depression in teenagers and young adults (ages 13-25 years) because it creates false expectations, negative self-perception, an attitude of comparing with others, and diminished self-esteem. Heavy use of social media can cause anxiety, lack of focus on studies and work, loneliness, etc.
Increased Screen Time
Using phones and other digital gadgets for a longer period of time in a day (more than 14 hours) is harmful for children and adults. These issues arise because prolonged screen exposure can disrupt the body’s biological systems, particularly by causing sleep disturbances.
Fear of Missing Out (FOMO)
Fear of Missing Out or FOMO is the leading cause of depression in Gen Z people. FOMO refers to the anxiety of missing out on exciting or interesting events that provide rewarding experiences and that others might be receiving. It causes social comparison with others, frequent phone use, anxiety, poor sleep patterns, higher stress levels, behavioral changes, etc.
Cyberbullying
Gen Z often lacks awareness and caution when using social media accounts and sharing sensitive information online. Even a small loophole can invite serious risks such as cyberbullying, online fraud, and hacking, which may lead to mental health issues like anxiety and depression.
Early Warning Signs of Depression
According to the World Health Organisation (WHO), the common symptoms and signs of depression include:
- Lack of motivation in daily life activities for a longer period of time, which often reflects through a person’s behaviour
