Sleeping is a necessity, which, if we do inadequately, could lead to several health risks. However, not everyone requires the same amount of bedtime each night. Some people can manage on just four to six hours of shut-eye. Scientists have now found out the reason behind their superpower. Sleep is essential for all human beings to function. However, not everyone needs the same amount of sleep to survive the chaos of this world. Some people require seven to nine hours of shut-eye daily, while others can do just fine with only four to six hours of bedtime each night. These short sleepers are as well-rested as the rest of us who cannot do without our eight hours of daily sleep. There are several adverse health effects associated with sleep deprivation, including early onset of conditions like Alzheimer’s and increased risk of heart disease. However, people with this rare mutation can be fully rested even with fewer hours of sleep, compared to those who need a shut-eye of at least seven hours. As per the researchers, short sleepers not only thrive on less sleep but may also feel “worse” if they sleep more. Scientists hope the latest study will help them improve sleep quality and design better treatments for sleep disorders. “These findings advance our understanding of the genetic underpinnings of sleep,” scientists wrote, adding that it gives “further support for potential therapeutic strategies to enhance sleep efficiency”. So, if you are a short sleeper, now you know why you have that superpower.
