Physical activity and fatigue

If you don’t have much energy, it can be hard to keep active. But taking up regular physical activity during and after your treatment can help to reduce fatigue.

It can also improve your:

• energy levels
• sleep
• appetite
• general health
• mood
• strength
• weight
• sex drive (libido).

How to get started with physical activity

Lots of people find it hard to be more active. You might be worried that you’re not fit enough or feel frustrated that you’re not as fit as you used to be. Some treatments for prostate cancer can cause urinary incontinence, so some men worry about leaking urine when they exercise. You might also be worried about hurting yourself. If you have any of these worries, speak to your doctor, nurse or physiotherapist. They can give you advice on the best type of activity for you. 

Remember, any activity is better than none. Start doing what you can and build up slowly. There is lots of support and information available to help you get started, including the ideas below. You can also speak to your doctor, nurse or physiotherapist.

Light to moderate exercise can make you feel more awake. You could try:

• standing up and sitting down
• walking to the shops
• climbing stairs
• cycling
• fixing things around the house
• mowing the lawn
• vacuuming
• washing the car
• swimming.

If you do light to moderate exercise along with strength or resistance training, such as lifting light weights or using elastic resistance bands, this may be even more effective. You can even exercise from your chair or bed. Try lifting your arms and legs or bending and straightening them. This can help improve your movement and muscle strength.

If you’re on hormone therapy or have cancer that has spread to the bones, you may be at risk of weak bones. This can increase your risk of broken bones (fractures). It’s important to speak to your doctor, nurse or physiotherapist before you start a new activity or increase the amount of physical activity you do. They can talk to you about exercising safely and explain the types of exercise that are suitable for you.
