What you should know
Why do we need to sleep?
One of the vital roles of sleep is to help us solidify and consolidate memories. As we go about our day, our brains take in an incredible amount of information. Rather than being directly logged and recorded, these facts and experiences first need to be processed and stored, and many of these steps happen while we sleep. Overnight, bits and pieces of information are transferred from more tentative, short-term memory to stronger, long-term memory – a process called “consolidation.”
Researchers also have shown that after people sleep, they tend to retain information and perform better on memory tasks. Our bodies all require long periods of sleep in order to restore and rejuvenate, to grow muscle, to repair tissue and to synthesize hormones.

Practical exercise tips
- If you don’t usually exercise, try taking a 10-minute walk every day and build up the amount of time until you are walking 30 minutes a day, three times a week.
- Resistance exercise twice weekly also can be useful for improving sleep in people living with and beyond cancer.
