The Claim
Night shift work is associated with a 66% increased risk of cardiovascular disease among nurses with insomnia, even after adjusting for age, BMI, and work schedule, indicating that insomnia itself may be an independent cardiovascular risk factor in this population.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Nurses who work nights and have trouble sleeping are much more likely to develop heart problems, even when you account for their age, weight, and work hours—suggesting that just having insomnia might be a hidden danger for their hearts.
