We all know that sleep is vital to our physical and mental health. According to the NHS, better sleep is the biggest single contributor to feeling better, and adults who sleep fewer than 6 hours a night have a 13% higher mortality risk than those who sleep 7+ hours.
However, the impacts of sleep go far beyond our health. Everything from our athletic performance to our family life can feel the effects of poor sleep. And so can our careers.
The NHS Livewell campaign reports that the annual cost of lost sleep is around £30 billion, with 200,000 working days lost every year. Poor sleep can impact your mood, memory, and energy levels – all of which can have a detrimental effect on your work.
Decreased productivity and focus
One of the most immediate effects of poor sleep is a noticeable drop in productivity. Sleep deprivation impairs cognitive functions, including attention, concentration, and problem-solving skills.
This can lead to a decrease in work quality, missed deadlines, and a general decline in professional performance. According to the productivity experts at Zapier, poor sleep results in 23-45% of the population losing more than two weeks’ worth of productivity every year.
Impaired decision-making and creativity
You know that sluggish feeling you get when you’ve had a bad night’s sleep? Well, chronic poor sleep can leave you feeling like that all the time.
A well-rested brain is a fertile ground for creativity and sharp decision-making. So it makes sense that, when you’re running on insufficient sleep, your ability to think outside the box and make quick, effective decisions is significantly hampered. This can be particularly detrimental in roles that demand constant innovation and critical thinking.
Emotional instability and interpersonal issues
Most job roles require some level of teamwork – even if it’s just via email. But this becomes a lot more difficult when you’re operating on less than the required amount of sleep.
Poor sleep doesn’t just affect your cognitive abilities; it also impacts your emotional wellbeing. Sleep-deprived individuals often experience mood swings, irritability, and a reduced capacity to manage stress. This can strain professional relationships, leading to conflicts with colleagues and superiors, and might even harm client relations.
Long-term health risks and career longevity
Chronic sleep deprivation is linked to a range of health problems, including obesity, cardiovascular diseases, and mental health issues like anxiety and depression.
As well as harming your health, these challenges can also lead to increased absenteeism, reduced career longevity, and even premature exit from the workforce. The World Health Organisation reports that globally, an estimated 12 billion working days are lost every year to depression and anxiety.
Diminished learning and career growth
Sleep plays a critical role in memory consolidation and learning. With inadequate sleep, your brain’s ability to absorb and retain new information is impaired. Needless to say, this can be a significant barrier in continuous professional development and career advancement, as you’ll struggle to take on new information that’s essential for more senior roles.
Work–Life imbalance
Poor sleep often spills over into other areas of life, disrupting the delicate balance between personal and professional responsibilities. It can lead to a lack of energy for personal pursuits and family time, contributing to overall dissatisfaction and burnout.
Poor sleep isn’t just about feeling tired; it’s about the cascading effects that impact all aspects of your personal and professional life. Recognising the critical role that sleep plays in your career success is the first step towards making positive changes.
