Chronic Fatigue Syndrome and Sleep:

More Than Simply Feeling Tired

We all know what it feels like to be tired after a long day or a poor night’s sleep. But Chronic Fatigue Syndrome (CFS) is something very different.

People with CFS experience intense fatigue and exhaustion that does not simply go away. Physical or mental activity can make symptoms worse, and recovery may require much more rest than usual.

The impact can extend across everyday life, affecting both physical activities, such as going for a walk, and mental tasks, such as concentrating at work.

CFS is not simply about feeling sleepy. It is an ongoing sense of fatigue and exhaustion that can affect everyday functioning.

Fatigue and sleepiness are not the same

One of the key distinctions with CFS is the difference between fatigue and sleepiness.

People with CFS generally experience fatigue rather than feeling as though they could fall asleep at any moment. Excessive daytime sleepiness can be associated with different issues and is not the same as CFS.

It is also not uncommon for people with CFS to sleep for 12 hours or longer and still wake feeling unrefreshed. Some may also experience headaches when they wake.

For many people, sleeping in or taking a nap during the day can help manage feelings of exhaustion and restore some energy, making it easier to get through daily activities.

When sleep becomes another challenge

CFS and sleep difficulties can sometimes go hand in hand.

Some people may find it difficult to fall asleep, wake frequently during the night or wake too early in the morning.

A poor night’s sleep can make it harder to remember things or focus on tasks. It may also contribute to moodiness or irritability and increase sensitivity to pain.

For someone already experiencing CFS, these effects can make existing fatigue feel even worse.

The sleep cycle

Getting as much sleep as possible can be helpful, but maintaining a regular sleep pattern is also important.

Sleeping late into the morning and then going to bed late at night can create a pattern known as Delayed Sleep Phase Syndrome, which can bring its own difficulties.

Getting enough sleep

Sleep deprivation can be particularly challenging for people with CFS. It can worsen symptoms and may delay recovery.

People with CFS should aim to get at least eight to nine hours of sleep each day.

If a late night is planned, taking a nap during the day can be a useful way to prepare and help manage fatigue.

Building better sleep habits

For many people with CFS, sleep begins to improve as their other symptoms improve.

If getting to sleep at night continues to be difficult, it may be worth looking at sleep hygiene and the habits that support better sleep.

Improving sleep habits may help create a more consistent sleep routine and support the management of fatigue.

Seeking Help

Always seek the advice of a qualified medical professional if you are concerned about your sleep.
