Relaxing the body to sleep better during chemotherapy
Insomnia is one of the most common — and least addressed — effects during chemotherapy. Sarı and colleagues’ research tested a simple, drug-free tool: progressive muscle relaxation.
What the study found
In patients receiving chemotherapy who had trouble sleeping, practicing progressive muscle relaxation exercises was associated with better sleep quality. It’s an accessible technique that can be learned and repeated at home, without relying on medication.
What it means for you during treatment
Sleeping better isn’t a luxury during treatment: rest influences energy, mood, chemotherapy tolerance, and recovery. Having a concrete tool to fall asleep gives back some control.
How IronHumans applies it
The method integrates conscious breathing, relaxation, and recovery into the plan, alongside gentle movement, so your system doesn’t spend the whole process in permanent alarm and your body rests better.
