The Claim
Experimentally induced hyperinsulinemia in healthy young adults increases nocturnal systolic blood pressure from approximately 107 mm Hg to 113 mm Hg, resulting in the disruption of the normal circadian dip in blood pressure during sleep.
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.
In healthy young adults, artificially raising insulin levels during sleep causes nighttime systolic blood pressure to rise from about 107 mm Hg to 113 mm Hg, preventing the usual drop in blood pressure that occurs during sleep.
See the scientific wording
In healthy young adults, experimentally induced hyperinsulinemia elevates nocturnal systolic blood pressure from approximately 107 mm Hg to 113 mm Hg, disrupting the normal circadian dip in blood pressure during sleep.
High insulin levels during sleep reduce the activity of the nerve that slows the heart and relaxes blood vessels, causing the heart to beat faster and blood pressure to stay high instead of dropping at night.
What the research says
1 studyWhen scientists raised insulin levels in healthy young adults overnight, their blood pressure didn’t drop as much during sleep like it normally should — meaning their body’s natural nighttime relaxation of blood vessels was disrupted. This suggests insulin might be interfering with how the nervous system controls blood pressure while sleeping.
