Causes of Poor Sleep
In 2018, the National Sleep Foundation’s annual Sleep in America poll found that only 46% of poor sleepers thought they were “very effective” at getting things done each day. That means that there is a large percentage of unproductive people out there! And the list of of reasons that someone might be experiencing chronic sleep deprivation is long:- Stress: Stress is a normal part of being human, but if stress in your personal or professional life consistently keeps you tossing and turning, it might be a good idea to see a specialist or practice a few techniques to relieve anxious thoughts, such as exercise, meditation or even practicing gratitude.
- Health issues: There are a number of physical conditions that can impact our quality of rest, from actual sleep disorders to other issues such as kidney disease and heartburn. When one part of the body is not doing well, it tends to affect other aspects of our health, too.
- Life changes: It could be a new baby, a move or a job change — big life shifts tend to keep us up at night.
- Poor lifestyle habits: Lack of exercise, watching screens / playing video games late at night, and a poor diet can all contribute to low-quality sleep.
- Alcohol consumption: Alcohol is a depressant that can make you feel drowsy initially, but it quickly metabolizes during sleep. Your brain soon “rebounds” from this depressed state, leading to more frequent awakenings during the night, including microarousals that you may not notice but that can greatly impact your sleep quality and how you feel the next day.
- Caffeine: The National Sleep Foundation reports that in one day, the average person drinks about three 12-ounce caffeinated beverages. For most, coffee takes an average of 4-6 hours to be completely cleared from the body. Any caffeine consumed after 12 p.m. can impact your rest that night.
Productivity & Sleep Deprivation
Whatever the cause, there’s no question that sleep deprivation has a significant negative impact on work productivity. A recent study by RAND Corporation uncovered that the U.S. experiences the highest economic loss due to insufficient sleep compared to other countries — up to $411 billion a year and the equivalent of about 1.23 million workdays. A lack of sleep affects our mental functions and ability to perform on the job in many ways:Attention and Working Memory
Both attention and working memory are linked to the functioning of the frontal lobes in the brain, which are very vulnerable to sleep deprivation. When these two functions are impaired, our response times slow, and it becomes more difficult to complete everyday tasks.Ability to Make Sound Decisions
Nuanced, complicated decisions are made more difficult by a lack of sleep. The ability to balance risk and reward becomes impaired, and people are more likely to make impulsive choices that lack self-control and good judgement.Selective Attention
Selective attention is the ability to focus on specific information when other things are happening around you. One study of two groups — a sleep-deprived group and a group that was well-rested — found that selective attention was much harder for those that were sleep-deprived.Emotions
Research by the Hult International Business School found that 84% of those surveyed reported that they felt more irritable as a result of poor sleep, which can affect decision-making on the job and interpersonal interactions. A different study with 18 healthy, young adults found that, when shown a series of facial expressions ranging from friendly to threatening, individuals who had been awake for 24 hours perceived more faces to be threatening. The inability to recognize and react to the emotional state of others seems to be a consequence of poor sleep that can affect relationships. All of these factors play together when you’re sleep deprived to make you less than the best version of yourself on the job. If you’re experiencing them, it might be time to look into a solution for sleep deprivation to make sure you’re getting the rest you need.How to Sleep Better for a Better Work Day
Try these tips to get to sleep sooner and for a longer period of time:- Avoid screens an hour before bedtime.
- Keep a consistent sleep / wake schedule, going to bed and waking up at the same time every day — and only sleep in an extra hour on the weekends. This regulates your body’s clock, helping you begin to get sleepy at the same time every night.
- Exercise– vigorous activity will tire you out the most, but even light exercise will help you fall asleep faster.
- Keep your bedroom between 60 and 67 degrees. As you fall asleep, your body temperature cools to prepare for rest and a lower temperature in the room will help facilitate this function.
- Practice a consistent, relaxing bedtime ritual – like taking a bath, brushing your teeth, and cozying up to read.
