Guide to fighting fatigue

23 Jan 2023 • 13 min read

Do you always struggle to stay awake while your friend is raring to go? Part of the answer could lie in your DNA, but a whole range of other factors play an important part in how fatigued we feel.

Luckily you can put a stop to extreme tiredness starting today.

Why do I suffer from fatigue?

Research has revealed those who experience energy slumps may have a gene mutation that controls the amount of energy in our cells. It becomes active when our fuel stores start to deplete, such as during exercise.

If it’s faulty, this process is active even when you’re at rest, making you feel tired even though you’re not doing much. Conditions such as depression, anaemia, fibromyalgia, and an underactive thyroid can also affect your energy levels.1

A lack of iron causes anaemia, so up your intake of iron-rich foods like lean red meat and broccoli, while an iron supplement may also help.

An underactive thyroid causes everything to slow down, so tiredness is a common symptom. Ask your GP for a test if you suffer from weight gain, sensitivity to cold and irregular periods too.

If you live with fibromyalgia, you may experience a range of different symptoms, and fatigue can be one of them.2

Fatigue can vary from person to person, with some feeling mild tiredness to feeling completely exhausted with no energy to do anything.

Your body clock could also trigger fatigue. We now spend most of our time indoors, under office lighting, so we’re not exposed to the natural daylight our body clock needs.

This has a knock-on effect on our sleep quality, which could trigger insomnia.3

If you’re suffering from persistent tiredness, which doesn’t improve with sleep or gets worse with exercise, it could be chronic fatigue syndrome (CFS).

You might also experience problems concentrating, a sore throat, tender lymph nodes, dizziness, and joint pain.4

If you’ve felt this way for at least four months, ask your GP to carry out some tests to rule out CFS.
