We all know how groggy and out of sorts we can feel if we don’t get enough sleep. But two studies have shown just what an impact sleep deficiency can have on our body and our mood.
Getting less than six hours’ sleep a night for a week can alter more than 700 genes in our bodies, according to research from the University of Surrey. The immune system and how the body reacts to stress were the areas most affected by lack of sleep, the researchers found. Getting enough sleep is therefore crucial to replacing cells in our body to maintain healthy functioning.
This isn’t always easy though, especially for working parents. A separate study by workplace provider Regus found that a third (34%) of working parents sacrificed sleep to fit in all their work and personal commitments. Yet three-quarters find themselves sucked into the culture of ‘presenteeism’ because their workplaces prize a long-hours culture.
Work-life balance is a hard one to get right. “Lack of sleep is clearly detrimental to worker health and happiness,” says Regus UK MD Steve Purdy. Perhaps that’s something to reflect on next time you set your alarm extra early or find yourself burning the midnight oil.
