Sleep Tight, Happy Dreams: The Perfect Mattress

A good night's sleep is essential for our health and well-being, but many people struggle to get the recommended amount of shut-eye. The quality of our sleep is often influenced by our outlook on life. A multiyear study led by Professor Rosalba Hernandez found that optimistic people who view the glass as half full tend to sleep better. The research, which included over 3,500 participants, revealed that higher levels of optimism were associated with a 78% increase in the likelihood of reporting very good sleep quality. This phenomenon is the idea behind the slogan Don't Worry, Sleep Happy, used in an ad campaign for Emma Mattresses. The campaign features a character named Frank and was created by MOTOR Kommunikation GmbH, Berlin.

Optimism and its impact on sleep quality

Research has found a strong correlation between optimism and sleep quality. A study published in the journal Behavioral Medicine found that optimists tend to sleep better and longer. The study, which included 3,500 young and middle-aged adults in four US regions, revealed that participants with higher levels of optimism were more likely to sleep for 6-9 hours each night and were 74% less likely to have insomnia.

These findings build on previous studies that have suggested a link between optimism and better cardiovascular health. Optimism has been found to have beneficial influences on physical health outcomes, and this research adds to the growing list of health-relevant outcomes associated with dispositional optimism.

Optimism is characterised by the general expectation that good things will happen in the future. Optimists tend to engage in greater proactive coping, which is an adaptive orientation for dealing with stressful events. They also engage in positive self-regulatory behaviours when dealing with stress, which can have downstream benefits.

The study by Dr Rosalba Hernandez and her team examined 3,548 participants, aged 32-51, who took part in the Coronary Artery Risk Development in Young Adults (CARDIA) study. Participants' levels of optimism were measured using a 10-item survey, which asked them to rate on a five-point scale how much they agreed with positive and negatively worded statements. Scores ranged from 6 (least optimistic) to 30 (most optimistic).

The researchers found that with each standard deviation increase in participants' optimism scores, they had 78% higher odds of reporting very good sleep quality. This suggests that optimism may be a contributing factor to better sleep, alongside other factors such as a new mattress, limiting late-evening alcohol consumption, and regular exercise.

While the exact mechanism through which optimism influences sleep patterns is not yet fully understood, the researchers hypothesise that positivity may buffer the effects of stress by promoting adaptive coping strategies, enabling optimists to rest peacefully.

These findings highlight the importance of psychological factors, such as optimism, in promoting healthy sleep patterns and overall well-being.

The link between stress and sleep

Stress and sleep are closely linked. Research has shown that stress often impacts sleep quality and duration, and insufficient sleep can, in turn, increase stress levels.

The Impact of Stress on Sleep

When individuals are stressed, the autonomic nervous system (ANS) releases hormones such as adrenaline and cortisol, triggering what is known as the "fight-or-flight" response. While this reaction was vital for human survival during the early stages of evolution, nowadays, non-life-threatening issues can activate this response, including problems at work or relationship difficulties.

Chronic stress can cause the nervous system to remain in a heightened state of arousal for extended periods, negatively impacting physical and mental health. This state of hyperarousal can delay sleep onset and cause rapid, anxious thoughts at night, leading to sleep deprivation. According to a National Sleep Foundation survey, 43% of people aged 13-64 have reported lying awake at night due to stress at least once in the past month.

The Impact of Sleep Deprivation on Stress

Sleep deprivation can have severe consequences on both physical and mental health. It can lead to an increased risk of heart disease, stroke, and depression, as well as negative mood, low energy, difficulty concentrating, and a general inability to function optimally.

Breaking the Stress-Sleep Cycle

Reducing stress levels in the evening is crucial for improving sleep duration and quality. Lifestyle changes, such as mindfulness meditation and physical exercise, can effectively lower stress and enhance sleep. Additionally, adapting a healthier diet, reducing caffeine and alcohol intake, setting boundaries between work and personal time, and seeking support from loved ones can also help alleviate stress.

It is important for individuals struggling with stress or sleep deprivation to seek help from mental health professionals and support systems, as trying to manage these issues alone can be detrimental.

The science behind mattress advertising

Sleep is an essential aspect of human health and well-being, and it's no surprise that the phrase "Don't Worry, Sleep Happy" has been used in mattress advertising. This phrase taps into the growing awareness of the link between mental health and sleep quality.

The mattress industry has recognized the impact of sleep on overall health and happiness, and this particular advertising slogan was used by Emma Mattresses in a 2019 TV ad campaign. The campaign introduced a character named 'Frank', presumably to add a human element to the product and create a connection with potential customers.

The science behind the slogan is based on research that suggests a strong connection between optimism and sleep quality. A multiyear study led by Rosalba Hernandez, a professor of social work at the University of Illinois, found that participants with higher levels of optimism reported better sleep quality. The study included a large and diverse group of over 3,500 individuals across four US cities.

The results, published in Behavioral Medicine, indicated that with each standard deviation increase in optimism scores, participants were 78% more likely to report very good sleep quality. This finding highlights the potential stress-buffering effect of positivity, which may help optimists rest more peacefully. According to Hernandez, optimists tend to cope with problems more actively and interpret stressful events in a more positive light, reducing worry and ruminative thoughts during the sleep cycle.

The mattress industry, therefore, has a scientific basis for its advertising strategies when promoting a good night's sleep as a path to happiness. By addressing sleep quality, mattress companies are indirectly promoting the mental health benefits that come with a good night's rest, which is an appealing proposition for consumers.

Tips for better sleep

Optimism is key to a good night's rest, according to a multiyear study by the University of Illinois at Urbana-Champaign. The research found that participants who scored higher on an optimism survey were 78% more likely to report very good sleep quality. So, maintaining a positive outlook and focusing on the bright side can help you sleep better.

To improve your sleep, try to actively address the challenges you face. Optimists tend to tackle problems head-on and interpret stressful situations in a more positive light, reducing worry and negative thoughts that can interfere with sleep. This mindset can help you throughout your sleep cycle, allowing you to fall asleep more easily and sleep soundly.

Additionally, creating a relaxing sleep environment is crucial. Ensure your mattress and bedding are comfortable and clean. It is recommended to change your sheets regularly, ideally more often than every three weeks. A cosy sleep environment can promote better sleep and reduce the risk of health issues associated with poor sleep quality, such as obesity and hypertension.

Finally, establishing a consistent sleep schedule can be beneficial. Aim to go to bed and wake up at the same time each day. This helps to regulate your body's internal clock and improve your overall sleep quality. By prioritising sleep and creating a peaceful bedtime routine, you'll be well on your way to a happier and healthier you.

The cost of poor sleep in the workplace

Sleep deprivation is a "public health problem" that affects not only individuals but also employers and the wider economy. Poor sleep has far-reaching consequences, from increased healthcare costs to reduced productivity and creativity, and even accidents in the workplace.

Increased Healthcare Costs

Employees with sleep disorders or insufficient sleep tend to have higher healthcare costs, which can impact employers' claims and expenses. Sleep disorders can lead to direct treatment costs and also contribute to overall poorer health, resulting in additional healthcare spending. For example, individuals with insomnia had average annual healthcare costs of $4,267 more than those without insomnia. This is partly due to the high cost of medication, with 75% of people with insomnia being prescribed medication.

Reduced Productivity and Creativity

Poor sleep impairs employees' ability to work effectively, reducing productivity, creativity, and overall work environment. This directly affects the business's bottom line and can hinder innovation and competitiveness. On average, 11.3 workdays per worker are lost each year due to reduced productivity from poor sleep, resulting in a loss of $1,967 per employee annually.

Accidents and Errors

Not getting enough sleep or having poor sleep quality increases the risk of accidents and errors in the workplace. This is particularly critical in high-risk industries such as healthcare, aviation, manufacturing, and transportation, where an accident or error can lead to major injuries or even fatalities. Even in industries not typically considered high-risk, such as consulting or retail, accidents or errors can result in financial costs and reputational damage. Employees with sleep disorders are twice as likely to have an accident at work and 1.5 times more likely to make an error.

Economic Impact

The economic costs of insufficient sleep are significant. A study across five OECD countries (the US, Japan, the UK, Germany, and Canada) found that insufficient sleep resulted in substantial economic losses, with the US losing up to $411 billion annually and Japan losing up to $138 billion. These losses are due to a combination of factors, including reduced labour productivity, increased healthcare costs, and the impact of accidents and errors.

Sleep-Work Connection

The link between sleep and work performance is evident, and addressing sleep deprivation can lead to improved productivity and reduced costs for employers. Implementing sleep improvement programs and providing support for employees' sleep hygiene can help mitigate the costs associated with poor sleep.

Overall, the impact of poor sleep in the workplace is extensive, affecting not only the individual employees but also the employers and the wider economy. By understanding and addressing the issue, employers can create a healthier and more productive work environment while also reducing economic losses.
