Space blankets, which are made of aluminum-foil-like Mylar are being distributed to people camping out in tents at Zuccotti Park in Manhattan’s financial district.

Medics say people are using them in their sleeping bags, tents or inside of jackets against to protect against the cold.

Medics say that in recent days that many of the people coming to receive assistance at two large tents for medical use, labeled red crosses, have come in concerned about of cold hands and feet. Others have come in soaked by the rain and have received assistance in getting dry.
