According to scientists from the University of Illinois, USA, the quality of sleep among optimists is much higher than among those who see the world in a dark light.
A team of researchers led by Rosalba Hernandez, professor at Illinois University, has identified the connection between perception of reality and the quality of sleep.
At the first stage of the study, over 3.5 thousand people answered the questionnaire to determine the degree of optimism. After that, the participants assessed the overall quality, duration and daily volume of monthly sleep and noted cases of insomnia and problems falling asleep. After 5 years, these same participants repeated their sleep monitoring. Additionally, about 600 people from the same group wore devices for monitoring their sleep duration, daily volume and quality of sleep for three days. A year later the monitoring was again repeated.
According to the results of the experiment, it turned out that optimists assess the quality of their sleep more positively. They slept for 6-9 hours on average and felt they had a good night’s sleep. 74% of them noted insomnia and daytime sleepiness less often.
Poor quality sleep is associated with many health problems, from obesity and high blood pressure to fatal diseases. Therefore, to take care of your health, it is useful to set yourself up to be optimistic and try to view life situations from a positive angle. Optimism is a natural barrier to stress and a mechanism for adapting to life circumstances.
But how can you readjust if you are not an optimist?
Optimism is a special way of thinking that can be worked upon. One needs to learn to notice positive moments in difficult situations, master the optimist’s behaviour model and begin to perceive reality positively. Ideally, positive attitudes are best combined with realistic assessments and critical thinking. The main thing is to start changing your approach to the future and your attitude to the present.

If your wife has been unfaithful to you, rejoice that she has betrayed merely yourself, and not your country.
And so forth… Follow my advice, good soul, and your life shall be jubilation”.
