The DGB Trade Confederation of Trade Unions in Germany has suggested that a short lunchtime nap will improve health as also will give more energy to work.
This is not a new idea. In some countries official lunch time nap is already allowed. It is reported that even in some of the European countries this was allowed earlier but stopped later. It is reported that even now in Greece some firms are allowing noon-time siesta.
It is not a bad idea after all.
