Getting enough sleep won’t just invigorate you; it could also help control how much you eat. A lack of sleep is linked to overeating—especially the overconsumption of junk food—which can lead to weight gain. It also has an impact on hormonal balance. Two hormones that help regulate hunger—ghrelin and leptin—are affected by sleep. Ghrelin stimulates appetite, while leptin decreases it. When the body is sleep-deprived the level of ghrelin spikes, while the level of leptin falls. This leads to an increase in hunger. Not only does a lack of sleep interfere with hunger signals, but there’s also the problem that less time in bed simply gives you more hours of the day to eat.
In addition to weight/metabolic issues, a lack of sleep also will cause more long-term and serious health problems. Some of the most serious potential problems associated with chronic sleep deprivation are high blood pressure, diabetes, heart attack, heart failure or stroke. Some research has linked a lack of sleep to an increase of the stress hormone, cortisol in the body and it’s now believed that people who experience short-term sleep deprivation are not able to process glucose as efficiently as those who get eight hours of sleep. This means that they have an increased likelihood of developing Type 2 Diabetes.
If a person is lacking rest but has continuous muscular activity, other issues such as cramping arise. Muscle fascia tears, hernias, and other problems usually associated with physical overexertion have also been reported in extreme cases of sleep deprivation.
Besides the many physical consequences of insufficient sleep, perhaps the most important consequences of sleep deprivation are deficits in working memory and attention. Lapses in ordinary day-to-day tasks can cause worrying results; from missing words or sentences while taking notes to omitting important ingredients while cooking. It appears that carrying out these tasks which require attention is in direct correlation to the number of hours the person sleeps each night.
As hard as it may seem, we need to make time for ourselves and for sleep. Doing this will ensure that you lead a much more productive and healthier life.
