Improved productivity

Our method can help to improve the quality of sleep of employees in high-pressure environments. Alertness, vigilance, and cognitive capacity are increased by Night Fit, due to reduced fatigue levels. As a result, the overall productivity and quality of work will improve.

Improved health

The increased risks of obesity and sleep disorders to which suboptimal sleepers are exposed are countered by Night Fit. Other health problems that are targeted are burnouts, cardiovascular diseases, and gastrointestinal diseases.

Less errors & mistakes

Improved quality of sleep will immediately result in better focus and concentration of employees. This reduces human error risks. By improving sleep patterns,  employees will be more competent, productive, and accurate.

“Hi Koos, I should be the one to say thank you! What a great workshop you gave, it resonated a lot with my current struggles! I hope to see you soon in a second session 😉 Best regards.” – AI Scientist Accenture


“Good energy, loved the Whodunit clip, interesting challenges. Many of the recommendations start small to help you take steps towards better focus; also triggered self-reflection about personal motivation to focus better and generally build healthy habits.” – Consultant Accenture


“Insightful. How things were known, but I learned new things about how the brain works. The online webinar dynamics including the challenges and assignments worked well. It is important to recognize that the workplace and life in general are more complex. Only if we recognize that a problem exists we can do something about it as an employer and employee.“ – Senior Compliance and Change Professional ING     


“Liked the session very much. It has given me a lot interesting insights that can help me to better organise my daily challenges. Due to our job responsibilities and because we are now working from home we share similar challenges every day.”-  Bart Compliance employee – ING


“The workshop was very good. I did appreciate all the little tips and tricks that can make life easier. Also, I like the theoretical knowledge about the brain and the associated activities. I liked the brain teasers. I believe it brings awareness of how to manage your time in the best interest of your own wellbeing while still being productive for the organisation. Understanding how our brains works brings added value.” – Viktoriya Expert Consultant C-Business Learning – ING


“The workshop was very good! Koos knows how to combine scientific research with practical tips in a fun way. The tips can be put into practice immediately and have already delivered immediate results in the first few days. Recommended! The content and themes are applicable in our industry, especially since everyone in the office faces the same challenges. ” – Casper Lawyer Houthoff


“Interesting useful workshop. In this type of ‘braintraining’ workshops the same things are often told, but there were a number of innovative points, with concrete advice (way of switching between tasks, work / switching to home, ‘active’ recovery and sleep) “– Lawyer Houthoff




Workshop: Night Fit ‘Work Hard, Sleep Hard’


Hello, my name is Koos Meijer, in the video below I explain what motivated me to help people to reach their full potential. The method called ‘Night Fit’ is taught to the participants in one or two interactive workshops called ‘Work Hard, Sleep Hard’.

Workshops for consultancy/law firms


As high-quality sleep helps our brain to function optimally, the Night Fit strategies and Somnoblue sleep glasses will help the consultants and lawyers to be more productive and to make better decisions. Additionally, it will help to improve their mental and physical health.

Clients: DLA Piper, Hogan Lovells, and EY


Workshops for offshore organizations


We have implemented the Work Hard, Sleep Hard strategies at various international offshore organizations. The training took place on location (e.g. Black Sea, North Sea, and the Mediterranean Sea). In total, we have trained more than 1000 offshore workers. Somnoblue sleep glasses were applied as depicted above.  The crew members currently apply the strategies in order to work safer and more healthy. Visit this page more information.

Projects include: Allseas, Transocean, Seaway Heavy Lifting, and Bluewater.


Workshops for professional athletes


Many things happen to the body of an athlete if the quality of sleep is improved from poor to moderate or from moderate to good. It will result in stronger immune functioning, faster metabolism, more balanced hormones, increased energy, and a greater level of focus during training and matches. However, if an athlete does not sleep optimally, it may suffer the opposite of all those benefits. Our workshops help athletes to improve their focus and performance.

Clients: ADO Den Haag, AZ Alkmaar, NAC, FC Utrecht, Royal Netherlands Football Association and The Royal Netherlands Rowing Association.


Healthcare professionals

The healthcare sector demands work to be continued through the night. However, human beings are not built to work during the night. Naturally, our body is programmed to ensure that energy, alertness, concentration, and other aspects relating to mental and physical performance peak during the day. In addition, our brain is ‘programmed’ to sleep at night. As a result, the inability to sleep and high fatigue levels are common problems in the healthcare sector.

Workshops and Somnoblue sleep glasses

Our sleep-enhancing strategies are taught to the participants in one or two interactive workshops. In addition, at the end of the workshop, each participant will receive their own pair of Somnoblue glasses. This will help healthcare workers to more fully recharge their brain and body between their shifts, and thus increases their overall performance and resilience to fatigue risks.


Workshops for the Military

High quality sleep between (night) shifts is essential for soldiers to ensure effective mental and physical recovery. High quality sleep is essential for soldiers to ensure optimal physical and mental recovery, and to perform safely during training and missions.

We’ve introduced the Night Fit strategies at the Dutch military in order to improve the quality of sleep in stressful environments. Together with the Centre for Man and Aviation, we conducted tests of Night Fit at the Air Operations and Control Station (Nieuw Milligen), the Force Protection (Volkel), and at the Royal Netherlands Air Force (Mali Africa).

Quotes from participants


Gegard: “I see progress so far, I fall asleep more quickly and I sleep longer. So far, I’m happy with the results.”

Gegard Mousasi – Five Times world champion MMA

“Interesting workshop, based on good research. There is a great amount of knowledge in the area of sleep and fatigue which has not yet reached the general audience. There is also much to learn about how to get the right information to the “customer i.e. the person that needs it the most”. Fatigue Management should be seen as improving performance and not as “sleeping in your own time”. Especially in aviation, the tools discussed in the workshop can be used to adjust circadian rhythms. Also, the tips and advice to improve sleeping patterns are of added value. –

– Erik – AME (Air Force)

“What stuck with me the most is that you need to have enough quality sleep in order to function at your full potential and thus be able to perform well. I keep using the glasses because I have the feeling that I feel fitter and I can get more out of myself on training and in competitions. “

Calvin (Ajax)

“A good night’s sleep is extremely important. That’s what Koos of KM Human Factors Engineering made us clear with his workshop. The tips and special glasses have already boosted our night’s sleep and focus. Jorrit (Audittrail)

“It works for me, since using it I sleep better and feel less tired, it’s comfortable for me to use. The last years before Night Fit it was very hard for me to get good sleep.” – Roseli (Seaway Heavy Lifting)

“Hopefully in the future, those with sleeping problems will use the Night Fit method to help them overcome their insomnia, instead of using sleep medication. And thus, improving their focus during work and being able to work more safely. As a medical professional I know sleeping well is good for their health and well-being.” – Celedonio (Allseas)


Night Fit, the benefits


Maximizing human potential at ‘high performance organizations’


All high-performance organizations have one thing in common: they intend to maximize human performance while, at the same time, wanting to keep their employees fit, happy, and healthy. Targets are set at high levels and errors can be very costly. Therefore, optimal focus, alertness, and good sleep are required. However, as anyone in a high-pressure position will tell you, a good night’s sleep is all but a given. Poor sleep increases the risk of fatigue, which leads to suboptimal performance, health, and wellbeing.

“Enhanced sleep quality helps me concentrate better on tasks, and results in faster troubleshooting of daily issues and problems. Also it helps me being in a better mood, not feeling stressed.”  – Abramovic (Allseas)


Night Fit workshops and Somnoblue glasses for shift work environments


In your life, you will sleep between 25 and 30 years. Good sleep is essential for your health, mood, and performance. By working night shifts you are exposed to artificial light at night and early morning, which affects your biological clock, resulting in a delay of melatonin production. For these people, it is not only harder to fall asleep, but if the melatonin level is suppressed for a longer period of time, it may have a negative effect on your health. The blue light blocking sleeping glasses that Somnoblue offers, filter the majority of light with a wavelength smaller than 530 nanometers. Also, these glasses filter all blue light from all directions. By doing this, our brains receive a signal that night has come. This results in an optimized production of melatonin and may help you achieve a better quality of sleep. Currently, our glasses are applied at 8 of the 10 largest hospitals in the Netherlands (e.g. Leiden University Medical Center, ACM and Radboud University Medical Center). Read more.
