Sleep is essential for a person’s health and well-being, according to the National Sleep Foundation (NSF).
Individual sleep needs range from being 6 to 8 hours. However, it is recommended in adulthood 8 hours of sleep. And, contrary to common myth, the need for sleep doesn't decline with age but the ability to sleep for six to eight hours at one time may be reduced. (Van Dongen & Dinges, Principles & Practice of Sleep Medicine, 2000).
Good sleep habits bring visible benefits not only to health, but also to productivity and attention / concentration.
Some examples of more concrete benefits are:

  1. Sleep helps reduce stress (the lack of rest hours can lead to the production of a high level of stress hormones; deep and regular sleep can help prevent this).
  2. Sleep can improve your memory (memory is badly affected when your sleeping hours are not enough, because when your body is at rest your brain is processing and storing your memories).
  3. Sleep could reduce your chances of diabetes (some research studies have shown that not getting enough sleep may lead to type 2 diabetes by affecting how your body processes glucose).
  4. Sleep helps your body to strengthen your immune system (your body produces extra protein molecules that can strengthen your ability to fight infections while you sleep).

Most people are not aware of the importance of sleeping on a daily basis and how it impacts negatively on their quality of life and their productivity throughout the day, whether at work or on other tasks.
The question that arises is:”Have you ever thought about the importance that a good night's sleep can have on your day and your productivity over the same day?”
Dan Pardi, researcher on the thematic of sleep and CEO of the human of, a personal health performance platform states “A good sleep regimen can practically turn one employee into two. It’s not just that we get more work done, we also have far better access to mental performance needed to do our hardest work — like writing, dynamic speaking, or innovative creativity.” With this statement Pardi demonstrates the relationship between his sleeping habits and his performance at work.

Situations such as irritability with co-workers, lack of concentration and feeling of permanent tiredness are examples of consequences of lack of sleep.
With this, we can see that there is a growing need for gauging and measuring our mental fatigue so that we can manage our energies.

Many companies are already sensitized to this topic, starting to investing on technical tools to optimize their workers performance.
An example of an existing application in the market for this specifically purpose is Perfometric. This application allows you to control your tiredness levels in real time, generating alerts and optimizing breaks for peak performance.

This performance enhancement software uses computer interaction metrics and advanced machine learning system to get the actual results and thus to correctly detect the level of fatigue and thus contribute to a correct allocation of energy, so as to achieve a better performance by combining a correct break and rest routine.
