Skipping Sleep Isn’t Just Making You Tired – It May Be Making You Sick

Skipping Sleep Isn’t Just Making You Tired

What if I told you sleeping more may be the answer to all of your problems? Okay, that may be a stretch, but it might be the answer to some. Surprisingly, a lack of sleep isn’t just making you feel tired but may also contribute to an increased risk of illness, slower brain processing, and weight gain. If you were looking for an excuse to sleep more, we have just what you need.


Sleep and Disease Risk

According to the Division of Sleep Medicine at Harvard, lack of sleep is associated with medical conditions such as diabetes, high blood pressure, and heart disease.1These chronic conditions may even shorten life expectancy. Studies have shown that potentially harmful effects of sleep deprivation are typically associated with stress. This can lead to an increase in blood pressure, inflammation, and difficulty controlling blood glucose levels. Specifically, hypertension, stroke, coronary heart disease, and irregular heartbeat seem to be more common in individuals with sleep complications. Sleep apnea in particular may be considered a predictor of cardiovascular disease.2


Reduced Cognitive Function

The American Insomnia Survey from 2012 discovered shocking results. It is estimated that insomnia was associated with 7.2% of all costly workplace accidents and rack up around $31.1 billion annually.3 A sleep deprived-brain simply can’t function to the best of its ability. In fact, if you haven’t slept, your ability to learn new things may drop by up to 40%.4 This is because sleeping helps strengthen your mind as you snooze. Sleep is also responsible for strengthening memories and linking new memories with older ones. Adequate sleep isn’t just important for your health but the safety of others as well. Harvard reveals that drowsy driving causes 1 million crashes, 500,000 injuries, and 8,000 deaths each year in the United States. They even point out that just one night of sleeplessness can impair judgment as much as a blood-alcohol level of 0.10 percent!6 Don’t pass up your sleep tonight.


Weight Gain

Trying to drop a few pounds but can’t seem to shed the weight? Make sure you are getting enough sleep. Studies show that sleep deprivation may contribute to a modest increase in future weight gain and incident obesity.5 Specifically, people who typically sleep less than six hours per night are more likely to have a higher body mass index (BMI). Individuals who sleep eight hours per night seem to have a lower BMI. This may be due to the fact that our bodies secrete appetite-suppressing hormones as well as energy metabolism and glucose processing hormones during sleep.1


Don’t let a lack of sleep get in the way of your health. There are numerous ways to encourage healthy sleeping habits such as turning off electronics before bed, going to bed at the same time every night, and following a consistent exercise routine (early in the day or evening based on how exercise makes you feel). Certain supplements may also promote sleep such as calcium and magnesium (or a warm cup of milk before bed), valerian root, passionflower, and L-tryptophan. It is also important to consider that too much sleep is associated with poor health as well.1 The CDC recommends at least seven hours or more per night for individuals over 18 years old.7 If you still have difficulty sleeping, always discuss additional options with your health care provider. Sweet dreams!
