Why Good Sleep Is Important
The responsibilities of many of us do not conclude at the end of the day. As a result, many people are sacrificing sleep time in order to keep up with demanding workloads and hectic lifestyles. Staying up a few extra hours to work more or waking up earlier to get a jump-start on the day, may seem like a simple compromise. However, according to the National Sleep Foundation, cutting yourself short on sleep can have serious consequences on both your mental state of mind and physical well-being.
Lack of sleep can make you irritable and impatient. You may also have trouble concentrating and remembering new information. Consequently, daily activities become more difficult, hindering work performance. In fact, according to a recent NSF poll, Sleeplessness, Pain and the Workplace, It costs US employers an estimated $18 billion in lost productivity.
Caffeine, a popular stimulant, is used by many people to help wake up in the morning and/or to remain alert during the day. While moderate use of caffeine has not been linked to any health risks, too much caffeine can lead to physical dependency, and withdrawal symptoms will include headache, fatigue and muscle pain.
Without proper sleep the immune system begins to weaken, leaving a person more susceptible to air born viruses such as common cold and the flu. Medical research has also shown that insufficient sleep impairs the body’s ability to use insulin, which can lead to the onset of diabetes.
Hypertension, and cardiovascular problems are also risk factors since interrupted sleep adversely affects the normal decline of blood pressure.
Research by Dr. Van Cauter reveals that people who don’t get enough sleep have lower levels of leptin, an appetite-regulating hormone. Low levels of leptin lead to an increase in appetite. Furthermore, the most appealing foods for those low on energy are often sweets or refined carbohydrates that are high in calories and low in nutrients.
Combined with a sluggish metabolism due to lack, weight gain is inevitable.
