Source: Sleeping Too Much or Not Enough May Have Bad Effects on HealthFewer than six and more than ten hours of sleep per day are associated with metabolic syndrome and its individual components, according to a new study. Researchers at Seoul National University College of Medicine found that compared to individuals who slept six to seven hours per day, men who slept fewer than six hours were more likely to have metabolic syndrome and higher waist circumference. Women who slept fewer than six hours were more likely to have higher waist circumference. Sleeping more than ten hours per day was associated with metabolic syndrome and increased levels of triglycerides in men, and with metabolic syndrome, higher waist circumference, higher levels of triglycerides and blood sugar, as well as low levels of 'good' cholesterol (HDL-C) in women. The authors found that nearly 11% of men and 13% of women slept less than six hours, while 1.5% of men and 1.7% of women slept more than ten hours. Although the biological mechanisms that underlie the association between sleep duration and metabolic syndrome remain unclear, several potential processes have been reported. These include elevated levels of hormones which increase appetite and caloric intake or reduce energy expenditure in people who sleep less than seven hours per day, which may lead to increased waist circumference and development of obesity. The authors caution that the cross-sectional, observational nature of this study does not allow for conclusions about cause and effect. Estimates of sleep duration were based on self-report data rather than objective measures and may reflect 'time in bed', actual time spent asleep or time people believed they slept. Also, as the study did not distinguish between daytime naps and nighttime sleep, their impact on health could not be assessed separately.

Is there any impact on the heart? I heard somewhere that if you didn’t get enough sleep that it would affect your heart negatively in some way shrug

Just look at this and see how many studies published about it. Bad sleep affects your whole body and if it becomes a long-term habit, there would be serious problems.
