Six reasons you’re always tired

Struggling with insomnia is bad but at least it explains why you feel exhausted. But what if you are sleeping enough but you still feel tired all the time? 

About one-third of adults feel tired most of the week. Given our 24/7 lifestyles, it isn’t a huge surprise. But what is the cause? We’ve put together the top causes of excessive fatigue for you below.

1. Stress and anxiety

When we are experiencing stress or anxiety - whether positive (weddings, moving home etc.) or negative (job loss, relationship breakdown etc.) - it has a physiological response on our bodies. It triggers our fight-or-flight system which increases our adrenalin, and dips into our glucose reserves. Our bodies aren’t able to sustain this heightened state and it quickly impacts our energy levels.

2. Depression 

If you consistently have a low mood, lacking in energy, have little pleasure in doing things, and feel tired all the time, you might be depressed. If you think you might be suffering from depression, reach out to your doctor.

3. Underactive Thyroid

Hypothyroidism, also known as underactive thyroid, occurs when your thyroid is unable to produce enough hormones for your body. Common symptoms include tiredness, depression and weight gain. It can be diagnosed through simple blood tests and treated with medication.

4. Iron deficient anemia

Caused by lack of iron, anemia can cause excessive tiredness, shortness of breath, pale skin and heart palpitations. It can be easily diagnosed through a blood test and treated with iron tablets.

5. Sleep apnoea

Your breathing starts and stops throughout the night. Symptoms include tiredness, difficulty concentrating, mood swings and headaches upon waking. There are many causes of sleep apnea but the most common include drinking alcohol, smoking, obesity, and/or sleeping on your back.

6. Alcohol

Although it might initially seem like a sleep aid, alcohol interes with our ability to sleep deeply and negatively impacts our quality of sleep. You can enjoy a little tipple here and there, but try not to drink within two hours of bedtime.


Still feeling tired? If you have made positive lifestyle changes (7-8 hours of sleep each night, reducing things like stress and alcohol consumption etc) but you are still feeling tired throughout the day then you may need medical support. Please reach out to your GP or health practitioner.
