Many homeless people sleep outside in doorways, parks, bus shelters, or other unsuitable places. They often have complex physical and mental health needs with root causes that are complex - relationship breakdown, mental health issues, addiction or childhood trauma. These are not issues that can be tackled quickly; people will often need help and support for many years to ensure they never end up back on the streets. The Salvation Army warns that people risk dying on the streets this winter as the cold weather continues to bite, even though new government figures for England and Wales show a slight decrease in deaths of homeless people. When it is very cold, the Salvation Army works with local councils to keep people as safe as possible, putting the homeless up in communal spaces in Lifehouses and operating a number of night shelters run in partnership with local churches.
