Three Sleepless Nights May Harm Your Heart

A new study shows that even short-term sleep deprivation activates inflammatory proteins in the blood linked to cardiovascular disease. After just three nights of sleeping four hours per night, healthy young men showed increased levels of proteins associated with heart failure and coronary artery disease.

What Poor Sleep Really Does to Your Brain

Chronic sleep disorders and short-term sleep deprivation affect different regions of the brain, highlighting distinct neural impacts. A meta-analysis of 231 brain studies showed that chronic sleep disorders alter regions involved in emotions and memory, while short-term deprivation primarily affects attention and movement regulation.

Poor Sleep Alters Immune Cells, Increasing Risk for Inflammatory Diseases

A new study reveals that even a single night of sleep deprivation can alter immune cell profiles to resemble those seen in obesity, a condition linked to chronic inflammation. Researchers found that sleep-deprived individuals had increased levels of non-classical monocytes, immune cells associated with inflammatory responses, similar to patterns observed in obese participants.

Sleep Loss Weakens Brain’s Ability to Block Unwanted Memories

New research reveals that sleep deprivation hampers the brain’s ability to suppress intrusive memories, a process critical for mental health. The study found that well-rested individuals could engage the right dorsolateral prefrontal cortex to inhibit unwanted memories, while sleep-deprived participants struggled.

Poor Sleep Linked to Difficulty Controlling Unwanted Thoughts

Sleep deprivation impairs brain regions responsible for suppressing unwanted thoughts, contributing to mental health challenges. Functional neuroimaging revealed reduced activation in the prefrontal cortex and increased hippocampal activity in sleep-deprived individuals, suggesting memory control deficits.

Sleep-Deprived Memories Restored by Common Medications

Researchers have found that sleep deprivation can hide, rather than erase, memories in mice, and that these memories can be restored using existing drugs. The study demonstrated that roflumilast, an asthma medication, could recover social memories, while vardenafil, an erectile dysfunction drug, restored spatial memories.

Sleeplessness Makes You Feel Up To Ten Years Older

Researchers unveiled a link between sleep quality and subjective age, demonstrating that insufficient sleep can make individuals feel significantly older. Through two studies involving over 600 participants, they found that each night of inadequate sleep contributed to feeling 0.23 years older, with sleep restriction causing participants to feel on average 4.4 years older.

Blood Test Detects 24-Hour of Sleep Deprivation

Researchers developed a blood test capable of detecting 24-hour sleep deprivation with high accuracy, offering promising applications for enhancing safety in various contexts. The test, which combines specific markers in the blood, was shown to identify individuals who had been awake for more than 24 hours with up to 99.2% accuracy under laboratory conditions.
