“Anorexia has been found to interrupt normal sleep patterns, possibly due to malnutrition and excessive weight loss,” says Wellman. Research suggests that anorexics get more non-REM sleep and less REM sleep than people of normal weight, resulting in next-day tiredness. Bulimia is often characterized by eating binges and purges during the night, interfering with a good night’s sleep.
