Stop reading the news and take up yoga. That's what some therapists in the United States are telling patients stressed out by a nasty presidential campaign in which two unpopular candidates are in a tight race for the most powerful office in the world.

While some patients are unhappy with the idea of a Hillary Clinton presidency, most are worried about Donald Trump, a blunt-spoken, insult-spewing New York businessman who has never held public office, according to interviews with seven therapists across six states and the District of Columbia.

The therapists said their patients have complained of difficulty sleeping, irritability and heart palpitations. They said they have advised clients to limit exposure to the news and take up breathing exercises and yoga to calm down.
