Sleeping myths debunked: Getting fewer than five hours a night increases risks of heart disease, strokes and early death and alcohol before bed DOESN’T help you nod off, study finds

  • New York University published the study which looked into sleep and health
  • They searched more than 8,000 websites, news reports and publications 
  • Dr Rebecca Robbins said: ‘We have extensive evidence to show that sleeping five hours a night or less consistently increases your risk for adverse health consequences’
