The problem of suicide is complex and complex, and seasonal changes are particularly noticeable.

Psychologists have been studying it since 1974, and over time, numerous studies have produced some striking findings.

In 1974, psychologist WK Zung and colleagues set out to explore the seasonal changes in suicidal behavior.

This study opens the door to exploration of the relationship between suicide and seasons.

The research at that time laid the foundation for subsequent research.

After 2010, Danish and American researchers collected and analyzed 37,987 Danish suicide cases that occurred between 1970 and 2001. They found that the risk of suicide rose significantly between April and June. This discovery has played a role in promoting the further development of research.

Early studies have revealed that suicide rates do vary between seasons, and while the data are not entirely consistent across studies, the phenomenon is enough to draw public attention.

The study found that the impact of seasonal changes in suicide risk in patients with mood disorders was significantly greater than that in people without the disease. The risk of suicide in patients is strongly correlated with season, but not in those without the disease.

This conclusion is supported by many studies.

For patients with mood disorders, seasonal changes can have varying degrees of impact.

As the seasons change, changes in light hours have an impact on their circadian rhythms, which in turn affects their psychological conditions.

Changes in the amount of time they spend in contact with dependents at home may also be a factor.

At the beginning of the new semester, their contact time with their children is significantly reduced, which may cause psychological changes in the children, which may in turn increase the risk of suicide in a certain season.

Lighting is an important environmental factor to consider.

Peaks of suicide and depression are thought to be triggered by changes in intensity, duration and periodicity of light.

Research in Greece pointed out that the day before a suicide event, the amount of sunlight radiation and the possibility of suicide showed a clear upward trend.

This change is closely related to the adjustment of the day and night cycle. Advancing the light time may slow down the patient's day and night cycle, leading to mood swings and sometimes even restlessness.

In addition to lighting, other environmental factors also play a role.

A Danish study involving 13,700 suicide cases showed that the likelihood of suicide is closely related to the concentration of pollen in the air.

When the pollen concentration exceeds 30 grains per cubic meter, the number of suicides per week increases by 13.2%.

Researchers pointed out that with the advent of spring, the number of allergens such as pollen and dust increases, which can cause an inflammatory response in the human body.

French sociologist Émile pointed out that suicides are more common in spring, mainly because interactions between people become more frequent.

In spring everything starts to come back to life, people's activities increase, relationships and exchanges become more frequent.

In this case, people with weak psychological endurance or who have mental illness themselves will face numerous changes and interactions, and their psychological pressure will increase, which may increase the risk of suicide.

This differs from the condition of prisoners, whose suicidal behavior does not appear to be affected by seasonal changes.

Their daily lives remain almost the same, reflecting how changes in human interactions have a significant impact on suicide rates.

People with mental illness are much more likely to commit suicide after a suicide attempt than others.

This is a very dangerous situation.

If you have tried unsuccessfully to commit suicide, if the environment has not fundamentally changed, or if the mental illness still exists, you will easily fall into despair again.

This particularity makes suicide prevention for patients with mental illness must be more stringent.

When people try to understand why someone chooses to end their life, we should not easily attribute suicidal behavior to individual shortcomings or mistakes.

Suicide is often a product of mental health and environmental variables.

Despite our understanding of neurotransmitters and biochemical mechanisms, however, the complex and burdensome daily lives experienced by individuals are equally critical.

Suicide should be understood correctly so that we can better care for those who are suicidal.

How do you think we can better help people with suicidal tendencies mitigate the effects of seasonal factors?
