Fatigue is different to tiredness, as it cannot be reduced by sleep alone. Many people living with a chronic illness such as PoTS experience fatigue that lasts a long time, or comes in waves. If this is not managed, it can begin to affect day to day life.
There are several reasons why you may feel fatigued:
The effects of fatigue are many and can impact upon every system in the body.
Physical: You may feel very tired and wonder why sleep is both difficult and unhelpful in solving your tiredness. Because of this, your energy levels may be affected, which could lead you to engage in less activity. This is understandable; however, inactivity can lead to muscle stiffness and pain.
The good news is that while PoTS-related fatigue cannot be taken away completely, there are so many things you can do to manage it. The strategies on this page can help you to feel more in control of your fatigue, but they do take commitment and do not always have an immediate effect.
Keeping an activity diary is a great place to start, as it will allow you to record your activity and rest. Over time, this can help you to recognise patterns in your day and also what is making your fatigue worse.
The following is a real life example of a ‘good day’:
6.30am Shower/get dressed/dry hair
7am Get the kids ready for school and have breakfast
8.30am School run
10am Work emails/presentation preparation ****
11am Walk the dog
12pm Lunch
1pm Housework
2pm Cup of tea/rest
3pm School run
4pm Prepare dinner
5pm Dinner time ****
6pm Bath kids
8pm Put kids to bed
9pm Check emails/watch TV
10.30pm Bed
11pm-7am Sleep
RED – high energy demand
ORANGE – medium energy demand
GREEN – low energy demand
BLUE – rest
PURPLE – sleep
**** – fatigue spike
We are able to see that this person has engaged in nine red activities, two orange (one of which is screen time, less than two hours before bed and sleep) and two green activities. Interestingly, there are only two periods of rest over a 16.5 hour time period. While this person has only experienced two ‘fatigue peaks’, they may go on to do less the next day, but experience more fatigue. This is known as a ‘boom or bust’ cycle, which will be talked about further down the page.

Top tip for keeping an activity diary
It is important to remember that your colours may differ, as for one person a red activity may be walking the dog, but for another it may be having a bath. Have a think about which activities will take which colours. Do not forget to include mental and emotional activity on there too!
Once you have your activity diary, you can go on to pace. Pacing is all about balancing activity and rest to bring about improvements in your fatigue levels. It offers you the chance to control the effects of PoTS and in time can lead you to be able to do more.
It is important to remember that activity includes both mental and emotional tasks as well as the more obvious physical ones. It can be tempting to do too much on a good day in order to make the most of your energy; however, this can often leave you with nothing in reserve over the following days. This is known as a ‘boom or bust’ cycle mentioned above.

Top tip for pacing- do a little less on ‘good’ days to enable you to achieve more on ‘not so good’ days.
Many people with PoTS adapt their activities of daily living to make them easier and do a great job of this. But it is important to note that changing the ways we do things can be very difficult, as we get into habits and routines over a period of time.
Occupational therapists consider all needs – physical, psychological, social and environmental – and aim to increase function and quality of life. They use a number of techniques to do this, including equipment provision (grab rails, wheelchairs, perching stools, bath boards), graded rehabilitation, fatigue management and improving community access.
If you do not feel you are managing your activities of daily living and this is impacting on your quality of life, your GP might be able to process a referral to your local community occupational therapy team.
Top tip for adapting activity – think hard about how you can make each activity a little easier and try it out for a minimum of two weeks.
