Of the 4,000 people polled for Legal and General, more than half said they do not exercise enough while 45 percent were concerned about sleep, the BBC reported. More than one-third of respondents reported feeling run-down most of the time, 28 percent complained of stress and 25 percent feel depressed much of the time.
Issues like smoking appeared less important to many, with 17 percent concerned about exposure to passive smoke and one in eight upset about not being able to give up smoking.
People were more worried about sanitary conditions in hospitals than about waiting times.
Only 2 percent were concerned about sexually transmitted diseases.
Tessa Webster, the insurance company's customer services director, said the survey shows that the public is concerned about health and well-being.
"The issue is that the majority of people are less obsessed on major issues such as diet and passive smoking and are far more concerned with the impact that busy lives are having on their health: stress, sleep deprivation, lack of time for exercise," she told the BBC.
