         Women who followed most aspects of a healthy lifestyle, including   
         healthy body weight, not smoking, regular exercise, adequate   
         sleep, high quality diet, and moderate alcohol consumption, had   
         about half the risk of long COVID compared with women without any   
         healthy lifestyle factors, according to a new study.

   FULL STORY   
   ==========================================================================   
   Women who followed most aspects of a healthy lifestyle, including healthy   
   body weight, not smoking, regular exercise, adequate sleep, high quality   
   diet, and moderate alcohol consumption, had about half the risk of   
   long COVID compared with women without any healthy lifestyle factors,   
   according to a study led by Harvard T.H. Chan School of Public Health.   
      
      
   ==========================================================================   
   "With ongoing waves of COVID-19, long COVID has created a serious   
   public health burden. Our findings raise the possibility that adopting   
   more healthy behaviors may reduce the risk of developing long COVID,"   
   said Andrea Roberts, senior research scientist in the Department of   
   Environmental Health and senior author of the study.   
      
   The study appears online February 6, 2023, in JAMA Internal Medicine.   
      
   It's estimated that 8-23 million Americans suffer from long COVID,   
   which is defined as having COVID-19 symptoms four weeks or more after   
   initial SARS-CoV- 2 infection. Symptoms can include fatigue, fever,   
   and a variety of respiratory, heart, neurological, and digestive symptoms.   
      
   The researchers analyzed data from more than 32,000 female nurses in the   
   Nurses' Health Study II, who reported on lifestyle in 2015 and 2017 and   
   reported history of SARS-CoV-2 infection from April 2020 to November 2021.   
      
   During that time, more than 1,900 participants contracted COVID-19. Among   
   these, 44% developed long COVID. Compared to women without any healthy   
   lifestyle factors, those with five or six had 49% lower risk of long   
   COVID.   
      
   Among the six lifestyle factors, maintaining a healthy body weight and   
   getting adequate sleep (seven to nine hours daily) were the ones most   
   strongly associated with lower risk of long COVID. The results also   
   showed that, even among women who developed long COVID, those with a   
   healthier pre-infection lifestyle had 30% lower risk of having symptoms   
   that interfered with their daily life.   
      
   The authors noted that one possible explanation for the associations   
   they observed is that, based on prior research, an unhealthy lifestyle   
   is associated with increased risk of chronic inflammation and immune   
   dysregulation, which have been linked with increased risk of long COVID.   
      
   "In the past decades, scientists have accumulated evidence that healthy   
   lifestyle is good for overall health. However, in the U.S. for example,   
   70% of the population do not have a healthy body weight and 30% do not   
   sleep enough.   
      
   Findings from this study suggest that simple lifestyle changes, such   
   as having adequate sleep, may be beneficial for the prevention of long   
   COVID," said lead author Siwen Wang, research fellow in the Department   
   of Nutrition.
