Sleep deprivation is one of the most overlooked public health crises. Chronic sleep deprivation — consistently getting fewer than seven hours of quality sleep — has profound consequences for virtually every body system.
Even a single night of poor sleep reduces reaction time, impairs judgment, and weakens memory. Going 24 hours without sleep impairs performance like a blood alcohol content of 0.10 percent. Sustained sleep loss is linked to depression, anxiety, and neurodegenerative diseases including Alzheimer’s.
Chronic poor sleep elevates blood pressure, increases inflammation, disrupts insulin sensitivity, disrupts hunger hormones, and weakens immunity. People sleeping fewer than seven hours are roughly three times more likely to catch a cold.
Growth hormone (tissue repair) drops with poor sleep. Testosterone declines. Cortisol becomes chronically elevated, creating a vicious stress-sleep cycle.
Improving sleep should be treated with the same urgency as any health priority. Yu Sleep addresses common root causes — nervous system overactivation, disrupted circadian signaling, insufficient deep sleep. Read about the benefits of better sleep or order today.
