Getting too little sleep reduces your productivity

The negative effects of sleep deprivation extend beyond the person, as one study shows; those who haven’t had enough shut-eye are less likely to be helpful to others, according to studies of their attitudes and the activity of their brains and social networks. The experts conclude that sleep’s significance lies in the fact that it pertains to a crucial part of human life.

Needless to say, you must have it: Numerous studies have shown the critical role that sleep plays in maintaining human health and productivity. Sleep disorders are linked to a wide range of complicated issues. Instances of cardiovascular disease and diabetes are more common, and the overall mortality rate rises. Depression and other mental health problems have also been related to a lack of sleep. It was previously known that various mental affects had a chilling impact on several facets of social conduct in this setting. “More and more evidence suggests that not getting enough sleep may have negative consequences for your health and the health of those around you, even complete strangers,”

Here, Ben Simon and her coworkers zeroed attention on a subset of what’s often referred to as “prosocial conduct,” using three distinct lines of inquiry to determine how much sleep deprivation impacts people’s propensity to aid others. First, 24 healthy volunteers’ levels of helpfulness were assessed using an altruism questionnaire, and their brain activity was monitored using functional magnetic resonance imaging (fMRI). These studies were performed both after participants had had a full night’s sleep and again after they had been sleep deprived.

Evidence showed that individuals’ levels of helpfulness reduced dramatically following sleep loss. The researchers reported that the findings of the fMRI studies appeared to represent the cause: As sleep deprivation progressed, it became clear that the brain areas involved in the so-called “Theory of Mind” network were less active. This network is engaged when we contemplate the wants of others; what are they preoccupied with at this same moment? Is anything wrong? Ben Simon asks, “Do they need assistance?” Following sleep loss, the operation of this network looked degraded. When we attempted to communicate with others, it felt like certain brain regions were unresponsive.

Part two of the research included gathering data from over a hundred online respondents. Using the specialized inquiry approach, we also documented their particular degree of helpfulness. Over the course of many nights of reporting on sleep duration and quality, this phenomenon occurred regularly. “We discovered that overnight loss in sleep quality predicted an overnight reduction in the desire to assist other people,” writes Ben Simon. To be more precise, “those who had bad sleep the night before stated that they were less ready and less motivated to serve others the following day,” as Simon puts it.

The final section of the research looked at a database of information on charity gifts made in the United States from 2001 to 2016. When studying the effects of daylight saving time, the researchers zeroed in on the day after the transition. The statistical analyses revealed a consistent 10% decrease in contributions. However, this decrease in generosity was not seen in areas of the nation where the clocks were not adjusted. The findings support the following hypothesis: “Even a relatively little amount of sleep deprivation – in this example, only the loss of a single hour – appears to have a quantifiable influence on people’s generosity and, therefore, on their altruism.”

Scientists draw the conclusion that a lack of sleep significantly decreases people’s propensity to aid others. This finding is consistent with studies showing that persons who are sleep deprived become more withdrawn socially. Overall, sleep deprivation makes people more antisocial, which has various effects on our survival as a social species, according to Walker. With the staggering statistic that in developed nations, over half of all adults report getting too little sleep throughout the working week, the potentially enormous societal relevance becomes evident. “Encouraging sleep might, then, assist to better form the social relationships we all experience on a daily basis,” argues Ben Simon.
