Can Weight and Diet Predict Sleep Quality:

 

Holistic-Health-Show-with-Dr-Carl-O-HelvieA new study presented at the American Professional Sleep Society this week in Denver concluded that an individual’s body composition and caloric intake can influence time spent in specific sleep stages . In the study 36 healthy adults spent two consecutive nights in bed for 10 hours at the hospital at the U of Pennsylvania. Physiological changes that occur during sleep was recorded on the second night on a Polysomnograph. Body composition and resting energy expenditures were assessed in the morning following the first night of sleep and food/drink intake were measured and recorded each day.

Results showed that body mass index (BMI), body fat percentage and resting energy expenditures were not significant predictors of sleep stage duration. However, overweight adults exhibited a higher percentage  of time spent in the rapid-eye movement (REM) stage of sleep than normal-weight adults.  REM sleep stage  is when dreams typically occur and is characterized by a faster heart rate and breathing and less restorative sleeping  than in non-REN stages. They also found that increased protein intake predicted less stage 2 sleep and predicted more REM sleep. Stage 2 sleep is the period when a person’s  heart rate and breathing are relatively normal and his/her body temperature is slightly lower. Researchers said further research is needed to determine whether changing protein intake alters REM sleep duration and to find the biologicval mechanism behind this relationship.
