How does the body change after only 3 nights of sleep deprivation?

Not getting enough sleep can lead to higher risks of heart disease, according to Neuroscience News . Researchers have previously shown that exercising when sleep-deprived puts mild stress on heart muscle cells.

Shift workers are prone to sleep deprivation.

Almost half of Swedes regularly experience sleep disorders, and this is particularly common among shift workers.

Researchers want to understand the mechanism by which lack of sleep increases the risk of cardiovascular disease, and then find a solution, according to Dr. Jonathan Cedernaes, associate professor at Uppsala University, who led the study.

Chronic sleep deprivation is a growing public health problem and in large population studies, increases the risk of heart attack, stroke, and atrial fibrillation.

The authors studied 16 healthy young men with normal body mass index and good sleep habits.

They were placed in a sleep lab, where their diet and activity levels were closely monitored over two testing periods.

During one session, they got three nights of uninterrupted sleep. During the other session, they got just four hours of sleep each night.

During both periods, researchers took blood samples in the morning and evening, including after participants performed a 30-minute high-intensity exercise session.

Sleep is important even for young people

Researchers measured levels of about 90 proteins in the blood. They found that levels of many proteins linked to inflammation increased when participants were sleep deprived.

Many of these proteins have also been linked to an increased risk of cardiovascular diseases such as heart failure and coronary artery disease.

"Many large-scale studies on sleep deprivation and cardiovascular disease risk have focused on older adults, who are already at risk for these diseases.

"So seeing increased protein levels in young, healthy people after just a few nights of sleep deprivation is remarkable. This means that sleep is important even for young people," said Jonathan Cedernaes.

“More research is needed to understand how these effects differ in women, older adults, people with heart disease, or people with different sleep habits,” he added.

The research will help develop better guidelines on how sleep, exercise and other lifestyle factors can be more effective in preventing cardiovascular disease.
