Common Causes For Tiredness

Tiredness isn’t just caused by lack of sleep. You may feel tired more often than not, and this could be down to an underlying condition or a certain lifestyle choice. But what can you do to stop feeling tired? Below are the most common causes of tiredness and how you can avoid them.

Medical conditions

There are lots of different illnesses that cause tiredness. They range in severity but most can be treated easily. The most common illness that causes tiredness, especially in women, is anemia. This occurs when the body doesn’t have enough iron to produce red blood cells, causing a lack of oxygen in your organs. Symptoms of anemia include tiredness and lethargy, heart palpitations and shortness of breath. It is most commonly caused by blood loss, but can also occur when there is a lack of iron in the diet. Treatment for iron deficiency anemia involves taking iron supplements to boost the low levels of iron in your body. This is usually effective

Other illnesses are chronic fatigue and thyroid problems. Chronic fatigue is a debilitating tiredness that causes severe lethargy and leaves patients feeling run-down for months on end. There is no one cause of this illness, but it can be linked to hormone imbalance and issues with the immune system. It is best treated with medication and physiotherapy. It is clear to see that these illnesses have similar symptoms, so it’s really important to visit your GP if to find out the exact cause if you experience any of them.

Depression and anxiety

Depression has some physical side effects. One of the most prominent symptoms of depression is lack of energy. People who suffer from depression often find it very hard to get a good sleep. A large contributing factor to depression is stress. Stress can exhaust the brain and lead to depression, which always seems to trigger more vicious cycle problems: you’re depressed so you become more stressful; you have trouble sleeping so you feel tired; you feel tired so you don’t feel like doing anything meaningful anymore’. This cycle of poor sleep fuelling tiredness means that, for some, depression can be extremely hard to beat.

Fortunately, there are many ways in which we can treat depression. It’s extremely important to seek medical advice if you have depression.

Poor quality sleep

When it comes to sleep, it’s all about quality, not necessarily quantity. Poor quality sleep can lead to many health issues and, of course, tiredness. If you have bad sleep, you are more likely to have impaired brain function, weight gain and increased risk of diseases. Sleeping less than 7-8 hours per night is linked to an increased risk of heart disease and stroke. Sleep deprivation can cause pre-diabetes in healthy adults, in as little as 6 days. It shows just how important it is to get a good night’s sleep. But how can we ensure that we get a high quality sleep every night?


The key to improving your sleep, and therefore your time awake, is by improving your lifestyle. There are certain factors which play a vital role in good sleep. You can easily improve your lifestyle by stopping these bad habits:

  • Dehydration– Not drinking enough fluids can make you feel sluggish and give you headaches. You should drink at least 6-8 glasses of water a day.
  • Disturbed sleep– Shift work and being woken up regularly can affect your mood.
  • Poor diet– Sugary foods, caffeine, and junk food all have a negative effect on your body. It’s also important not to skip breakfast or drink alcohol before bed.
