When was the last time you got 7 to 8 hours of sleep? If you can’t remember or want to laugh at such a question, you’re probably one of the 50 to 70 million Americans that have chronic sleep deprivation. And while it’s common to lose sleep every now and then, continually getting less than 7 hours can seriously harm your health.
Of course, on some nights, it just happens. Many of us can blame work, school, or jet lag. Or maybe you had that last cup of coffee just a little too late. However, a person with decent sleep habits can get back on track within a few days.
But what if you’re not that person? Adolescents and older people are more likely to suffer from chronic sleep deprivation. The risk also increases if you work crazy hours or night shifts, or if you have disorders like sleep apnea or insomnia. Because chronic sleep loss increases the risk of type 2 diabetes, heart disease, hypertension, depression, and early death, it’s vital to know the signs. From there, you can seek treatment depending
1. Daytime Sleepiness
After a night of poor sleep, it’s normal to feel groggy and tired. This becomes the norm if you have chronic sleep deprivation! You’ll be yawning the day away, especially while sitting still. So pay attention to how you feel on a daily basis. If you’re constantly feeling sluggish, don’t ignore it.
Constant daytime sleepiness can lead to “microsleeps” or dozing off in places other than your bed. This might happen while sitting on a train or in a public place, like a classroom. Can’t watch television without passing out? You
3. Poor Focus
The brain needs to rest and recharge at night. But without enough shut-eye, it doesn’t have time to repair itself. This can easily lead to poor concentration, focus, and attention. Decision-making will feel like running a marathon.
4. Frequent Mistakes
On that note, you’ll also be more prone to mistakes.2 Perhaps you forgot an ingredient in a recipe or sent an e-mail to the wrong co-worker. What’s worse is that making mistakes may also happen while driving, proving just how important sleep truly is.
5. Increased Appetite
Hungrier than usual? Blame the
6. Mood Issues
Getting little to no sleep makes you prone to mood swings, or emotional lability.5
Other common signs include irritability, stress, and anxiety. Plus, when you’re chronically sleep deprived, you have a higher risk of developing depression.6
7. Frequent Colds
Sleep literally fuels immune cells. During rest, they increase in number, re-distribute to the lymph nodes, and develop an immunological memory to remember foreign particles.7 But when you’re always running on empty, it’s common to have a cold that just won’t quit.
