The Claim
Adenosine accumulates during wakefulness and binds to neuronal receptors to promote sleep pressure and neural deactivation.
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.
When you're awake, your brain builds up a chemical called adenosine, which tells your brain it's time to sleep by slowing down brain activity.

What the research says
1 studyStudy: Astrocytic modulation of sleep homeostasis and cognitive consequences of sleep loss.
The study found that brain cells called astrocytes release a chemical (adenosine) that makes us feel sleepy, and when they don’t release it, we don’t feel as tired—even when sleep-deprived. This proves adenosine is key to why we get sleepy when awake.
