What your birthday reveals about your health
Incredible but true: according to a study, birthday has an impact on health. The risk of developing a mental illness is therefore higher in certain birth months than in others.
Relationship between health and month of birth
Back in 2012, a group of scientists at Queen Mary University in London discovered that there is a connection between schizophrenia, bipolar disorder, depression and the month of birth. In their empirical study, the team examined over 29 million English people – one of the three mental illnesses was found in around 58,000 people.
Based on these data, the experts found that babies born in winter were at higher risk for schizophrenia and bipolar disorder, with the main focus on January. According to the study, spring children are the most susceptible to depression – especially babies who saw the light of day in May. On the other hand, there is hardly any correlation between July birthday children and schizophrenia and November children and depression. Babies born in August and September, on the other hand, were less likely to have bipolar disorder.
Suicide and birthday – is there a relationship?
According to the National Alliance on Mental Illness (NAMI), around 90 percent of people who commit suicide have previously struggled with mental health problems. So it should come as no surprise that suicide can also be linked to birthdays. A team from the “British Journal of Psychiatry” evaluated the data of around 27,000 suicide victims between 1970 and 2001 in a paper – and related them to the months of birth. According to this, people born in April, May and June have a higher potential to put their suicidal thoughts into practice. In concrete terms: The risk was 17 percent higher than for people who saw the light of day in autumn or winter.
Why the season matters
The experts disagree on the relationship between birthday and health. One factor could be vitamin D: this is produced when our bodies are exposed to sunlight – a lack of it can lead to porous bones and rickets. Recent research has also found that too little vitamin D affects the nervous system and significantly affects the development of the brain. This could explain why babies born in winter and spring are at higher risk for mental illness.
