Girls who were 18- to 21-years-old and who sleep no more than 5 hours per day gained 1.9 pounds more over a period of a year than girls who slept 8 hours per day according to a study from researchers at the Harvard Medical School in Boston, Massachusetts, USA.

Those who slept at least 9 hours per night lost an average of 0.8 pounds after one year compared to those who slept 8 hours per night.

The study surveyed 5502 girls who were 14- to 21-years-old, however, this data was limited to those 18 to 21. REFERENCE
