It’s perfectly normal to experience tiredness from time to time. However, if you consistently find yourself asking, “Why Am I Tired?” and this feeling persists without a clear explanation, it could be a signal that something more is going on. Understanding the potential causes of persistent tiredness is the first step towards regaining your energy and well-being.
Common Causes of Tiredness and Fatigue
Many factors can contribute to feelings of tiredness and fatigue. Often, these are related to lifestyle choices and everyday situations. Here are some of the most common reasons why you might be feeling tired:
Lifestyle Factors
One of the most prevalent reasons for feeling tired is simply not getting enough sleep. Many adults need between 7 to 9 hours of quality sleep each night to function optimally. If you’re consistently falling short of this, sleep deprivation can lead to significant fatigue. Furthermore, difficulties falling asleep, also known as insomnia, can disrupt your sleep patterns and leave you feeling drained even if you spend a long time in bed.
An unhealthy lifestyle also plays a significant role in energy levels. A diet lacking in essential nutrients can lead to fatigue. Similarly, a sedentary lifestyle with lack of regular exercise can make you feel more tired in the long run. While it might seem counterintuitive, regular physical activity can actually boost your energy levels.
Mental Health
Your mental well-being is deeply connected to your physical energy. Stress, whether from work, relationships, or daily life pressures, can be a major drain on your energy reserves. Similarly, depression is often accompanied by persistent fatigue and a lack of motivation. Dealing with significant life challenges, such as bereavement or the demands of caring for a new baby, can also contribute to both mental and physical exhaustion.
Hormonal Changes
Fluctuations in hormones can also significantly impact your energy levels. Hormonal changes during puberty, pregnancy, and menopause are all known to cause tiredness. Pregnancy, in particular, brings about significant hormonal shifts and physical demands that commonly lead to fatigue throughout all trimesters. Menopause, with its fluctuating estrogen and progesterone levels, is also frequently associated with tiredness and sleep disturbances.
Medical Conditions
Sometimes, persistent tiredness can be a symptom of an underlying illness. Infections like glandular fever and COVID-19 are known to cause significant fatigue that can linger even after other symptoms subside.

Certain medical treatments and medicines can also lead to tiredness as a side effect. Chemotherapy, for example, is a cancer treatment known to cause drowsiness and fatigue during and after treatment.
It’s important to remember that while these common causes are often the culprits, unexplained and persistent tiredness could be a sign of a more serious medical condition. If you can’t pinpoint the reason for your fatigue and it’s been ongoing and worsening, it’s crucial to consult a healthcare professional rather than self-diagnosing.
Conditions That Can Cause Tiredness and Fatigue
While your symptoms can sometimes provide clues about the cause of your tiredness, it’s essential to seek professional medical advice for proper diagnosis. Here are some conditions that are often associated with tiredness and fatigue, along with related symptoms:
| Symptoms | Possible Cause |
|---|---|
| Tired during the day due to nighttime awakenings, gasping, snorting, or choking sounds at night, and loud snoring | Sleep apnoea |
| Lack of energy, noticeable heartbeats (heart palpitations), shortness of breath, and pale skin | Iron deficiency anaemia |
| Extreme tiredness, excessive thirst, frequent urination (especially at night), unexplained weight loss | Diabetes |
| Constant tiredness, restlessness, nervousness, anxiety, irritability, muscle weakness | Overactive thyroid (hyperthyroidism) |
| Severe fatigue lasting at least 3 months (significantly impacting daily activities), cognitive problems, memory and concentration issues, flu-like symptoms | Myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS) |
Things You Can Do to Help With Tiredness or Fatigue
Fortunately, there are many steps you can take to combat tiredness and fatigue, often starting with simple lifestyle adjustments.
Do
Making positive changes to your daily habits can significantly improve your energy levels.
-
Maintain a healthy diet and exercise regularly. Focus on balanced meals rich in fruits, vegetables, and whole grains. Incorporate regular physical activity into your routine, aiming for at least 30 minutes of moderate-intensity exercise most days of the week.
-
Establish a consistent sleep schedule and aim for 6 to 9 hours of sleep per night. Go to bed and wake up around the same time each day, even on weekends, to regulate your body’s natural sleep-wake cycle.
-
Wind down before bedtime. Engage in relaxing activities in the hours leading up to sleep, such as reading a book, listening to calming music, or enjoying a podcast.
-
Create a relaxing sleep environment. Ensure your bedroom is dark, quiet, and cool to promote restful sleep.

Don’t
Certain habits can exacerbate tiredness and should be avoided, especially close to bedtime.
-
Avoid smoking. Smoking has numerous negative health impacts, including disrupting sleep and reducing energy levels.
-
Limit alcohol consumption. While alcohol might initially make you feel sleepy, it disrupts sleep later in the night and can lead to fatigue.
-
Avoid eating heavy meals, caffeine, or exercising in the hours before sleep. These activities can interfere with your ability to fall asleep and stay asleep.
-
Limit screen time before bed. The blue light emitted from smartphones and screens can suppress melatonin production, making it harder to fall asleep. Avoid using electronic devices in the hour before bedtime.
When to Seek Medical Advice
While many cases of tiredness can be addressed with lifestyle changes, it’s important to know when to seek professional medical help.
See a GP if:
- You’ve been feeling tired for several weeks and are unsure of the cause.
- Your tiredness is significantly impacting your daily life, making it difficult to work, socialize, or carry out everyday tasks.
- You experience tiredness alongside other concerning symptoms such as unexplained weight loss, mood changes, or if someone has told you that you make gasping, snorting, or choking noises while you sleep.
Treatment for Tiredness or Fatigue
Treatment for tiredness and fatigue will depend entirely on the underlying cause. A doctor will conduct a thorough evaluation to determine the reasons behind your fatigue and recommend appropriate treatment strategies.
Possible treatments may include:
- Talking therapies, such as cognitive behavioural therapy (CBT), can be helpful in addressing tiredness related to mental health conditions like stress, anxiety, or depression, and in improving sleep habits.
- Advice on improving sleep hygiene can be provided to help you establish healthier sleep habits and routines.
- Lifestyle advice focusing on diet, exercise, and stress management can be tailored to your individual needs.
In some cases, a GP may refer you to a specialist for further investigation if the cause of your tiredness is unclear. You may need tests, such as blood tests, to check for conditions like anaemia, diabetes, or thyroid disorders.
Ultimately, understanding why you are tired is a journey that may involve self-reflection, lifestyle adjustments, and sometimes, medical investigation. By paying attention to your body and seeking appropriate help when needed, you can take proactive steps to overcome fatigue and improve your overall well-being.
