An exercise oncology program improves sleep quality in head and neck cancer patients undergoing chemo-radiation therapy
A randomized controlled trial of 70 head and neck cancer patients found that a 7-week exercise oncology program (15-20 minutes of brisk walking and resistance training) significantly improved Pittsburgh Sleep Quality Index scores from 13.97 to 7.09, while the control group's scores worsened from 13.06 to 14.14 (both p < 0.001). Urinary melatonin levels increased in the exercise group but the between-group difference was not significant after adjusting for baseline values (p = 0.372).

An exercise oncology program improves sleep quality in head and neck cancer patients undergoing chemo-radiation therapy The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 42/100 (low).
The Claim
An exercise oncology program improves sleep quality in head and neck cancer patients undergoing chemo-radiation therapy
This conclusion is most relevant to: Head and neck cancer patients (stage III, IVa, or IVb) undergoing chemo-radiation therapy, aged 18 years or above, any gender, with ECOG score < 2.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Efficacy of an exercise oncology program on sleep quality and circadian rhythm in head and neck cancer patients undergoing chemo-radiation therapy: a randomized controlled trial. (PeerJ, 2026) —
How It Works
The proposed biological pathway:
- ▸Exercise may enhance melatonin secretion
- ▸Improved circadian rhythm regulation
- ▸Reduced inflammation and stress
- ▸Result: Improved sleep quality
Who Might Benefit
Evidence fit by population:
- ▸Head and neck cancer patients (stage III, IVa, or IVb) undergoing chemo-radiation therapy, aged 18 years or above, any gender, with ECOG score < 2
Recommended Dose
15-20 minutes per session, five days per week for seven weeks
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Between-group difference in urinary melatonin was not statistically significant (p = 0.372), limiting support for circadian rhythm mechanism
- ▸Small sample size (n=70) and single-center design may limit generalizability
Frequently Asked Questions
What type of exercise was used in the program?▼
The program included 15-20 minutes of brisk walking (aerobic) and upper/lower limb resistance training.
How was sleep quality measured?▼
Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), a validated self-report questionnaire.
Did the exercise program affect melatonin levels?▼
Urinary melatonin increased in the exercise group but the change was not statistically significant compared to the control group after adjusting for baseline values.
Who was eligible for this study?▼
Patients with stage III, IVa, or IVb head and neck cancer undergoing chemo-radiation, aged 18+, with ECOG score less than 2, and without severe orthopedic or neurological conditions.
