Chess and Sleep...

No doubt, I am interested by the interactions between sleep and chess.

The article was published in Chess, November 1970.
The picture is coming from a very good article written by Edward Winter: some excellent anecdotes on Chess Grand Masters and Sleep.

Sleep... one third of our life.

For the members of this forum wanting to know more:

This paper is very encouraging for the chess players:
Abstract (Melodi Dinçel1, Aydın Acarbay, Oktay Kaya, Gülnur Öztürk, Necdet Süt and Levent Öztürk)
Chess game requires problem-solving skills and is related with all aspects of higher degree cognitive processes. The effects of regular chess practice on subjective sleep quality have not been known yet.
In this study, we aimed to investigate the subjective sleep quality of tournament level chess players. In total, 225 chess players (M/F, 185/40; Mean age, 25.7±9.5 year) were included to the study. National and international rating scores and the chess history of all participants were recorded. All subjects completed Pittsburgh sleep quality index (PSQI) and Epworth sleepiness scale. Correlation analyses were performed between the chess parameters and the sleep scores. In addition, we divided the study group into two subgroups based on the PSQI score. Group 1 (n=107) consisted of the subjects with a PSQI score lower than 5 whereas Group 2 (n=118) consisted of the subjects with a PSQI score equal to or higher than 5.
We found that there was no correlation between global and component scores of PSQI and chess ratings. The mean national and international ratings of Group 1 and 2 were comparable (National ratings, 1746±249 vs 1715±271; international rating, 1908±197 vs 1869±183; p>0.05 for both).
In conclusion, we suggest that regular chess practice does not impair subjective sleep quality and playing chess has the potential to improve subjective sleep quality through increased mental activity.

Enjoy!

Some gaming experiences are going much too far.
Specialists in Sleep and Psychiatry already discuss a new category of addiction disorders: Internet gaming addiction...
I see very well some of us and their addiction to play chess all the night... Fortunately we play on dedicated chess computers: we are very few exposed to the light of leds... responsible of blue light emission, highly consequential on the insomnia disorders.

Yes, it is true, we have chess players who play chess online for long hours...
Do they become addicted?

Some research was published on Short sleepers and sleep...
Short sleepers are people sleeping less than 6 hours, at least 3 times per week for at least 3 months according to the classical definition.

Title: Associations Between Sleep Patterns and Performance Development Among Norwegian Chess Players
Authors: Frode Moen, Maja Olsen and Maria Hrozanova
Published in Front Psychol. 2020; 11: 1855.

Abstract: An inherent part of elite-level chess are high emotional and cognitive stress loads related to performance development. Sleep is a crucial recovery strategy, previously implicated in athletic performance.
The main purpose of the current study was to investigate the associations between performance development and objectively measured sleep in a sample of 14 Norwegian chess players over a period of 120 consecutive days.
Seven of the chess players in the current sample had negative development in their International Chess Federation (FIDE) ranking score in the period of sleep monitoring, while 7 had positive development.
The sleep patterns of the chess players with positive performance development were different from the players with negative development – with higher amounts of deep sleep, less rapid eye movement (REM) sleep and lower respiration rate in the positive performance development group compared to the negative performance development group.
The findings are discussed in terms of existing knowledge on the importance of sleep stage distribution and sleep durations for athlete functioning, and in light of applied implications and possible future research.
