You might think that the worst thing about not getting sleep is being tired. And that definitely isn’t ideal. But, according to a small new study, one night of tossing and turning may also have unexpected effects on your body.
For the study, recently presented at this year’s meeting of the Radiological Society of North America (RSNA), researchers took blood and urine samples from 15 participants before and after a 24-hour radiology work shift. During that shift, participants got an average of three hours of sleep. The researchers also took measurements of participants’ blood pressure and heart rate.
Their results showed that, after going 24 hours with just a few hours of sleep, participants’ blood pressure and heart rate were both elevated. Plus, the blood and urine samples showed elevated levels of cortisol (a hormone associated with the body’s physiological response to stress) and several hormones related to the thyroid gland, which helps regulate many processes in the body, including temperature and metabolism.
