No effects of short‐term sleep restriction, in a controlled feeding setting, on lipid profiles in normal‐weight adults
Short sleep has been associated with cardiovascular risk. The aim of this study was to determine the impact of short‐term sleep restriction on lipid profiles and resting blood pressure factors in young, normal‐weight individuals (14 men, 13 women). Participants were randomized to five nights of either habitual (9 h) or short (4 h) sleep in a cross‐over design separated by a 3‐week washout period. There was no sleep × day interaction on lipid profile and blood pressure. Short‐term sleep restriction does not alter lipid profiles and resting blood pressure in healthy, normal‐weight individuals. The association between short sleep and increased cardiovascular risk reported in the epidemiological literature may be the result of long‐term sleep restriction and poor lifestyle choices.
