Many patients ask:
The answer is usually **YES**, as long as the exercise is light, safe, and based on how your body feels. In fact, gentle activity can help reduce fatigue, improve mood, and maintain strength.
1. Benefits of exercising during radiotherapy
- reduces fatigue
- improves appetite
- boosts mood and reduces anxiety
- helps maintain muscle strength

2. Safe exercises you can do
Choose light, low-impact activities such as:
- walking (5–20 minutes)
- gentle stretching
- simple home exercises
- slow stationary biking
- light yoga or breathing exercises
3. Exercises to avoid (for now)
Avoid activities that are too intense, such as:
- heavy weightlifting
- high-impact aerobics
- long-distance running
- basketball, volleyball, or contact sports
- activities under extreme heat (midday walking, outdoor labor)
4. If you are receiving treatment to certain areas:
Breast or chest wall
- avoid exercises that irritate the armpit area
- stretch gently to prevent tightness
Head & neck
You may feel weak or dehydrated; keep exercises very light.
Pelvis (cervix, prostate)
If you have diarrhea or fatigue, focus on rest and hydration.

It’s normal to feel more tired as treatment progresses. Adjust your exercise level depending on how you feel.
Stop exercising if you feel:
- dizziness
- shortness of breath
- chest pain
