This is what I read and something similar on another government type website and AI.

Suicide in Sweden
In 2019, Sweden had 14.7 suicides per 100,000 people. Historically, Sweden has had a high suicide rate, with the most suicides in the developed world during the 1960s. That may have been due, at least in part, to cultural attitudes regarding suicide and long, dark winters, particularly in the northern regions. The government responded to the crisis with social welfare and mental health services, and the numbers have dropped dramatically. Today, Scandinavian countries – Norway, Sweden, Denmark, and Finland – have very high happiness rates and relatively low suicide rates. However, the dark winters – 20 hours of darkness or more in each day in some areas – causes seasonal affective disorder (SAD), a form of depression, which has been known to correlate with higher rates of suicide.
Euthanasia, or physician-assisted suicide, is still illegal in Sweden but is accepted in some instances. A physician may not administer lethal drugs to a terminally ill patient, but he or she may end life support of the patient requests doing so and demonstrates that they understand the consequences. This form of physician-assisted suicide, known as passive euthanasia, is not included in suicide statistics. Active euthanasia, when a physician administers lethal drugs to a terminally ill patient with the patient and family's consent, may soon become legal in Sweden, as it is becoming more accepted in European countries.
