The number of prisoners in Sweden placed in long-term isolation has tripled in five years, rising from 140 to 450. Overcrowding and a lack of specialized facilities for inmates with mental health issues are key factors.

Jenny, whose son has been in isolation for five months, describes the severe psychological toll.

Experts warn that prolonged isolation can worsen mental health and increase the risk of reoffending.

Despite the growing need, the number of specialized mental health units in prisons has decreased, leading to long waiting times.

Critics argue this trend endangers both inmates and staff, as untreated mental health issues can lead to violence.
