The Truth About Optimism And Mental Health

An optimist is often defined as someone who generally has positive thoughts and expects positive occurrences in their life. This anticipation of positivity can have an all-encompassing effect on how an optimist confronts problems and copes with life's adversities. Optimists are often considered resilient to stressful situations and may lean on healthy coping strategies, which can benefit both their mental and physical health. 

While some researchers have concluded that optimism is a personality trait, you can choose to view life positively and increase your optimism. To begin, understanding the definition and benefits of living an optimistic life can be valuable.

What is optimism?

A concise definition of optimism is the tendency to have hope and confidence about future outcomes. In philosophy, optimism is a doctrine stating that this world is the best of all possible worlds, but the modern meaning may be better understood as a general expectation that good things will happen and that challenges can be overcome.

Real-life examples

The truth about optimism is that people can experience it in different ways. Some general examples of how optimism may appear in daily life can include: 

  • Starting a new job with positive expectations
  • Interpreting setbacks as temporary rather than as signs that something will go wrong with future events
  • Feeling excited about good events to come rather than worrying about things that might go wrong or that happened in the past
  • Choosing to believe that a difficult situation will improve over time and with effort

Is optimism a trait or a skill?

There is some debate about whether optimism is a trait or a skill

Some research indicates that optimism is a trait and may be related to how the brain works. One 2025 study used functional MRIs to examine the brains of participants and determined that “more optimistic individuals had similar neural representations in the medial prefrontal cortex (MPFC), while less optimistic individuals exhibited more idiosyncratic neural representations in the MPFC.” The researchers believe that this shows optimistic individuals prioritize positive events over negative ones.

On the other hand, some studies indicate that optimism may be a skill. Research suggests that optimism can be learned, even by those who may be considered pessimists. According to Sue Varma, clinical assistant professor of psychiatry at New York University, “Even if you were not born with this natural disposition to anticipate favorable outcomes and see the glass as half full, there are skills that you can learn.” Some of the recommended skills include: 

  • Noticing how you deal with uncertainty
  • Reframing these thoughts in a positive way
  • Envisioning the best possible outcome and the steps you can take to get there
  • Finding a sense of purpose

How optimism affects mental and physical health

Optimism can have meaningful effects on both mental and physical health, from psychological resilience to long-term physical wellbeing. Below, we take a closer look at what the research says.

Why optimists tend to cope differently

Optimists may cope with challenges differently from those who are more pessimistic. Research suggests that, in times of stress, people who are more optimistic are more likely to turn to approach-oriented coping strategies, such as problem-focused coping, support-seeking, and cognitive coping strategies. They may have a positive effect, that is, be more likely to experience positive emotions, which can also have a wide range of positive effects on mental health.

Optimism and future life events

How people think about the future can also shape how they prepare and respond to it. The above study also suggests that, in addition to having active coping skills, optimists also tend to be more likely to focus on managing and changing stressors, making plans to avoid stressful situations in the future, and reaching out for support. They may be more likely to anticipate good events and enjoy them for what they are, reframe bad events and see them as only temporary, which can lead to better outcomes in the future.

When optimism can support the recovery from mental health problems

Research also shows that optimism can be a crucial part of treatment for a variety of mental health problems, promoting overall mental health as well as helping to heal various conditions, including suicidal ideation, depression, anxiety, and trauma-related disorders. 

Optimism and physical health

Optimism can also have beneficial effects for physical health. Some research shows that optimism may

  • Have a 35% lower risk of cardiovascular events than those with lower optimism
  • Live on average 11 to 15% longer than pessimists
  • Have a lower incidence of age-related illnesses and reduced mortality levels

There may be a range of explanations for these effects. For example, optimists may be more likely to take better care of themselves by eating healthily, exercising, getting enough rest, and not smoking, or they may experience lower levels of stress hormones and inflammation, which can protect against disease.

The self-fulfilling prophecy effect

A self-fulfilling prophecy occurs when a person’s expectations impact their behavior, which may ultimately make the expected outcome more likely to happen. 

How expectations shape behavior

As mentioned earlier, optimists are more likely to have positive expectations about future events and may feel like things are moving in the right direction. Research suggests that believing that good things will happen in the future can act as motivation to take actions that may be more likely to result in good things—in other words, a self-fulfilling prophecy.

The dark side of optimism: When positive thinking becomes over-optimism

While optimism can have many benefits, being too optimistic can also have its downsides.

What “blind optimism” looks like

A blindly optimistic person looks on the bright side of life, no matter the outcome of its events. This type of over-optimism can cause them to believe that what they want to happen will indeed happen, regardless of any evidence to the contrary. They might also ignore negative information or the possibility of potential negative outcomes.

Blind optimism can sometimes contribute to a sense of success and fulfillment. At times, the force of will is so strong that you may be able to create positive outcomes through positive thinking. However, blind optimism can also cause you to miss vital information that might change your decisions about making what you want to happen, leading to a worse outcome.

Private optimism vs public despair

In cognitive neuroscience, private optimism and public despair is a phenomenon that was first defined by neuroscientist Tali Sharot. The idea is that people are optimistic about their own lives but are more pessimistic about public affairs and the greater society. Sharot speculates that this may happen because people may believe that they have control over their own lives but no influence on greater societal problems. Private optimism and public despair can lead people to engage in less action and be complacent about collective problems, or they may fail to prepare because they feel they are immune to larger threats.

Optimism bias and risk perception

Another potential downside to optimism can occur when positive expectations are disconnected from reality. This can be referred to as optimism bias, or the tendency to believe that the worst possible outcome is less likely to happen to you than to someone else.

Why people can hugely underestimate risk

Optimism bias is one of the recognized cognitive biases in psychology. It can distort risk perception and leave people unprepared for the challenges that may realistically occur. Some real-life examples can include: 

  • Skipping health and medical screenings or not taking precautionary action because you assume you won’t get a serious illness
  • Continuing to smoke because you’re convinced you won’t experience any health threats as a result
  • Not having an emergency fund because you assume that you won’t face any unexpected financial burdens

Developing greater optimism

Because optimism can be a choice, you can decide to be more optimistic and make that change. To do this, you may benefit from changing your thought patterns. A therapist can help you identify pessimistic thoughts and find their source. After identifying your unwanted thoughts, you can evaluate them to decide whether to keep those thoughts in mind or choose other thoughts to replace them.

Effectiveness of online therapy

Online therapy has been shown in studies to help those struggling with depression and related negative thinking patterns, finding that “internet-delivered treatments are effective, in particular if therapist guidance is provided.”
