Mixed

Chronic insufficient sleep (<6 hours/night) and circadian misalignment in military personnel cause significant mental and physical derangements, including increased risk for cardiovascular disease, PTSD, and cognitive failure.

Prioritize 7-9 hours of sleep as a non-negotiable part of your daily routine, especially before high-stress operations. Treat sleep with the same discipline as physical training. If you are struggling with sleep, address it early to prevent long-term health issues like cardiovascular disease or PTSD.

GoodSupportsHIGH confidence
The significant mental and physical derangements caused by degraded metabolic, cardiovascular, skeletomuscular, and cognitive health often result from insufficient sleep and/or circadian misalignment.
