Let’s begin with the very basic question, “Why mental health matters?

What Is the Importance of Mental Health?

Mental health plays a vital role in our overall well-being. It influences how we think, feel, build relationships, and navigate challenges. When our mental health is supported, we’re often more resilient, more engaged in life, and better equipped to cope with stress. Conversely, when we’re struggling mentally, even everyday tasks can feel overwhelming.

The Stigma Surrounding Mental Health

Mental health and societal well-being are deeply interconnected. When mental health needs go unmet, it can lead to broader effects, such as reduced workplace productivity, increased pressure on healthcare services, and additional demands on public institutions like law enforcement and the justice system. In contrast, promoting mental wellness can lead to healthier communities, a stronger economy, and an improved quality of life for all.

Mental Health Awareness Month

Raising awareness is a powerful step in reducing stigma. By encouraging open dialogue and replacing misconceptions with empathy and education, we can create a culture where seeking support is viewed as a sign of strength. Mental health is not just an individual concern; it’s a collective responsibility. Through understanding and support, we can build a more inclusive and resilient society.

What are the Causes of Mental Health Problems?

  • Life Experiences: According to the American Psychological Association (APA), childhood trauma is one of the major causes of mental health issues. In addition, abuse or grief of losing someone also contributes to the issue. These experiences leave a lasting impact on the patients.
  • Social Factors: Studies from Harvard Medical School state that factors like social isolation, poverty, and lack of support can contribute to mental health issues. Social factors also include ethnic issues, racial criticism, public abuse, etc.
  • Substance Abuse: Misusing drugs or alcohol is a major risk factor for developing mental health problems (source: National Institute on Drug Abuse (NIDA)). When such additions are not fulfilled, patients can get depressed and sick.
  • Biological Factors: Research published in journals like Nature Neuroscience suggests that genetics can also lead to mental health issues.

How to Improve and Maintain Mental Health?

  • Seeking Professional Help: Therapy, such as Cognitive Behavioural Therapy (CBT), is effective in treating depression, anxiety, and other disorders (source: National Library of Medicine).
  • Exercise: The Lancet Psychiatry says that physical activity can improve one’s mental health. That’s because exercise releases endorphins, which enhance mood and reduce stress. You can go out for a run when feeling anxious or depressed, or follow meditation exercises on a daily basis to balance your happy hormones.
  • Healthy Diet: Research in the American Journal of Clinical Nutrition shows that omega-3 fatty acids, found in fish, can improve brain function and reduce symptoms of depression. So, build a healthy diet and don’t forget to intake essential nutrients.
  • Sleep: Adequate sleep is critical for mental health. The National Sleep Foundation suggests that sleep deprivation can negatively affect mood, cognitive abilities, and emotional regulation.
  • Social Connections: The National Institute of Health (NIH) and other health organizations give special importance to building relationships with positive people. This plays an important role in feeling valued and heard.
