Feeling Constantly Tired? Here’s What You (and Your Team) Should Know About Fatigue

Fatigue is something most of us have experienced, but when tiredness becomes a daily struggle, it can impact every part of our lives, from productivity and mood to long-term health.

According to the National Sleep Foundation, more than a third of American adults report feeling tired every day. As a UK GP, I can confirm this is just as common here: fatigue is one of the most frequent complaints I see on triage lists. It’s a widespread issue that affects people across all professions, age groups, and backgrounds.

We encourage employers to share this article with employees to help raise awareness of fatigue, its causes, and practical steps for managing it. Better-rested employees are not only healthier, but more productive, focused, and engaged.

What Exactly Is Fatigue?

The World Health Organization defines fatigue as “a state of feeling very tired, exhausted, or sleepy, which can be physical, mental, or a combination of both.”

Fatigue can be caused by many things, including:

• Lack of sleep

• Stress

• Poor nutrition

• Underlying medical conditions like anaemia, thyroid problems, or sleep apnoea

Fatigue doesn’t just make us feel bad – it affects our overall performance. Research shows that sleep-deprived people make 37% more errors and are 60% more likely to experience workplace accidents. As Vince Lombardi once said, “Fatigue makes cowards of us all.”

The Most Common Cause? Poor Sleep

Most adults need 7–9 hours of sleep each night. Yet, nearly half of UK adults get less than 7 hours, and a third of young people get fewer than 5 hours – a dangerously low amount.

Lack of sleep not only leads to chronic fatigue but also increases the risk of serious health conditions like obesity, diabetes, and heart disease.

Other Key Contributors: Stress & Nutrition

Stress can affect sleep quality and be exhausting in its own right. It activates our nervous system and keeps us in a constant state of alertness, not ideal for winding down.

Diet is another important factor. Western diets that are high in sugar and refined carbohydrates often lead to “sugar crashes” and low energy levels throughout the day.

When to See a Doctor

Sometimes, fatigue can be a sign of something more serious. Conditions like anaemia, thyroid issues, sleep apnoea, and diabetes are just a few of the potential culprits. If fatigue is severe or ongoing, it’s wise to speak with a healthcare professional – especially if you experience symptoms like breathlessness, breathing pauses at night, or sudden weight changes.

How to Tackle Fatigue: Practical Steps

Here are some evidence-based strategies that anyone can try:

Prioritise Sleep

• Set a consistent sleep and wake time

• Avoid caffeine after midday

• Limit alcohol consumption

• Turn off screens at least an hour before bed

• Keep the bedroom cool, quiet, and dark

Manage Stress

• Incorporate regular exercise, mindfulness, or yoga

• Practice time management and avoid overcommitting

• Use stress-reducing techniques like journaling or breathing exercises

Eat for Energy

• Focus on a balanced diet with whole grains, lean proteins, and lots of fruits and vegetables

• Reduce processed sugar and refined carbs to avoid energy dips

Find What Works for You
No one sleeps perfectly all the time. Even short moments of rest or mindfulness during the day can help recharge the brain and body.

In Summary

Fatigue is common, but it’s not something we have to live with. By understanding the causes and making a few lifestyle changes, we can all take steps to feel more energised, resilient, and in control.
