A study warns: lack of sleep makes you selfish, disinclined to help anyone | Lifestyle

“The world sleeps badly,” was the title of a report published late last year by the German health magazine Medisana, which declared that “bad sleep has become a nightmare for the world.” In Germany alone, 34 million people suffer from permanent sleep disorders, About a third of workers feel tired and unable to concentrate.

Almost 10% of the population of Western industrialized countries (more than 100 million Europeans) suffer from a sleep disorder, and the results of the first pan-African and Asian sleep study showed that “sleep problems in the Third World are beginning to reach levels found in industrialized countries.”

And the problem is getting worse, despite repeated warnings from scientists that “poor sleep increases the risk of strokes and heart attacks, and can lead to high blood pressure, depression, cancer, diabetes, obesity and even the risk of death”. Studies show that “the vast majority (about 70%) do not take it seriously, and do not go to the doctor.”

The report also indicates that only about 50% of people come to work refreshed, rested and fit, because they realize the importance of good sleep, along with physical activity and a balanced diet.

Today, however, we are in the process of a new UCLA study that sheds light on an additional consequence of poor sleep.

Poor sleep means less altruism

According to HuffPost, the study, which was conducted by experts from the University of California, included the results of 3 previous studies; She showed that “lack of sleep can make a person tired, angry, less responsive to helping others, and people are more selfish after a bad sleep.”

The first study monitored the brains of 24 people who had a good night’s sleep versus a bad night’s sleep, then asked them to fill out a questionnaire about “helping behaviors” and write down what they difficult situations, such as their reaction to seeing an injured animal on the road, or their willingness to give up their seat for the elderly on a crowded bus.

When the researchers took MRI images of the participants’ brains, they noticed that the parts of the brain associated with empathy were less active after a night without sleep, and “the participants showed a significant decrease in the desire to help others, under sleep. -deficient conditions.”

The second study tracked more than 100 people online for 3 to 4 nights, with self-reported information measuring how much and how well they slept. The survey asked participants how often they woke up, how many hours they slept, and when they woke up. . The results indicated that “a night of poor sleep led to a reduced desire to help others.”

But the third study focused on the effect of daylight saving time on charitable giving, analyzing nationwide donation data from 2001 to 2016, and found that “transition to daylight saving time is associated with a significant decrease in altruistic behavior with money (giving), compared to the weeks before moving on. or later,” meaning that “the loss of one hour of sleep can lead to a worse mood, due to reduced empathic sensitivity to the needs of others.”

Screens before bed is a big reason

Anyone who wants to sleep well should avoid screens, as the blue light emitted by the TV, computer or phone can keep our eyes open at night.

It has been proven that blue light inhibits melatonin, the hormone that the body needs to sleep, and focusing on the phone does not give the mind a chance to rest after a long day, which is what certified psychologist Sasha Hamdani to the “HuffPost” newspaper, who says: “By surfing the Internet or switching between TV channels, we try to release the dopamine that is released when we see interesting things, which keeps the mind busy and active , and it is less likely to shut down after sleep.”

And the Medisana report notes that disrupted sleep “can be linked to our frequent use of cell phones and computers late into the night,” based on a 2017 survey conducted by the German Society for Research and Sleep Medicine (DGSM) which found that “68 percent of “People use their laptops and smartphones in the evening to keep up with their personal affairs or work-related tasks, such as answering emails. Many people also take their phones and tablets into the bedrooms, to use them late into the night. “

Electricity is the enemy of sleep

To help yourself fall asleep, certified sleep medicine specialist Jeffrey Dormer recommends spending time on your porch or patio, “to allow darkness and peace to calm your mind, rather than light and noise.”

The German Society for Sleep Research and Medicine also recommends adjusting the room temperature so that it is cool, as well as reducing caffeine and nicotine will improve the quality of your sleep.

It’s also important to have a bedtime routine, as certified sleep expert Carly Prendergast recommends, “In addition to other calming activities, such as taking a warm bath, reading a book, etc.; to regulate the circadian rhythm (the body’s sleep-wake) to help determine cycle).

The Medisana report recommends turning off electrical devices in the evening, including Wi-Fi, as “electricity seriously interferes with sleep, which can have a detrimental effect on electrical devices in sleep-standby mode.”

The importance of altruism to your health

Altruism has an important health benefit. If you don’t sleep well, you won’t be the best and most advanced because you lack the benefit of altruism, which is a vital value that can improve your well-being. Helping others not only makes you feel good, but also benefits your health, and studies show that helping others can lead to Less stress, and you can even maintain lower levels of inflammation in the body, since stress is at the forefront comes from the high cost of lack of sleep.
