Hi,
Is the following sentence correct? Is 'contact' with the nature' correct and is there any other way to refer to the same meaning?
In order to stay healthy, people should go to countrysides to contact with the nature more often.
Your phrasing sounds awkward.
You might say
to get in touch with nature
to experience nature
to get in contact with nature.
Also, say '. . people should visit the countryside . . .'. Use the singular form.
Best wishes, Clive
