Almost every child, teenager or adult in our society has a habit of sleeping late at night. Work, studies and entertainment are some of the reasons why people tend to stay up late at night. Watching movies, reading books or simply pondering over your whole day are so addictive that most of the people don’t realize the time which has passed. It may be fun to stay up with your loved ones watching movies or playing games, but it can have more negative effects for you than you think.
Experts are just beginning to understand how sleep affects just about everything you do. But they do suggest you look out for these scary side effects of skiping on sleep in your 20s:
1. Increased Risk Of Disease
In a recent study involving more than 54,000 adults, researchers found that people who sleep less than six hours per night were significantly more likely to have heart disease or diabetes, suffer a stroke or get obese.
2. Heightened Blood Pressure
Sleep loss stresses out your body and mind in a way that causes your blood pressure to spike. Over time, this could damage your heart, arteries, kidneys, and even bring about stroke, loss of vision, erectile dysfunction and a host of other health problems you seriously don’t want.
3. Weakened Immune System
Vaccines are designed to trick your body into creating antibodies that provide immunity to a particular disease or infection. But exhaustion weakens the immune system, so your body doesn’t produce enough antibodies it need. According to a study in which researchers administered hepatitis B vaccinations and measured patients’ antibodies before and after treatment, people who slept fewer than six hours a night were the least likely to respond to the vaccine and were 11.5 percent more likely to be unprotected from harmful pathogens out there.
When you don’t get enough sleep, your body naturally releases the stress hormone cortisol, says Dr. Shalini Paruthi, director of the Pediatric Sleep and Research Center at SSM Cardinal Glennon Children’s Medical Center in St. Louis, Missouri. It doesn’t matter whether you were up late to work on spreadsheets or to work on catching up on your favorite dramas, staying up late just causes stress.
5. Greater Risk Of Death
People who sleep less than five hours per night are 15 percent more likely to die from literally any cause, according to data from three massive studies. So yes, going to bed too late could decrease your life span.
6. Impaired Creativity
Neuroimaging studies suggest that the brain spontaneously reorganizes information when you rest, which could explain why it’s so much harder to focus and come up with ideas when you haven’t slept.
There’s something about exhaustion that turns you into Negative Nancy: In a two-year study in which 78 medical residents tracked their sleep and intermittently recorded their emotional responses to various stimuli, researchers found that fatigue intensified participants’ negative emotions. Sleep deprivation actually affects your mood even more than it does your motor and cognitive performance, according to a massive review of 19 original research studies published in Sleep. Meaning? You’re more susceptible to angry tantrums when you’re sleepy.
8. Lower GPA
Research suggests that college students who sleep the least earn lower grades than those who sleep nine or more hours per night. Your brain needs to cycle through certain deep sleep stages to store memories and solidify the things you learn. When you fall asleep, your heart rate and metabolic rate drop so your body can focus on those things, experts say. No sleep, no storage.
9. Poor Decisions
Many parts of the brain are involved in decision-making. When you don’t give your brain enough rest, it functions at half-mast, and you’ll end up making choices you would regret later on.
10. Twitchy Eyes
Fatigue can cause an awkward-looking eye spasm called nystagmus, which makes your eyeballs move even involuntarily, even though your head is still.
11. Fertility issues
While there’s no conclusive proof that sleep deprivation directly causes infertility, experts know that lack of sleep can stress you out and suspect it can also can interfere with your body’s circadian rhythm. Together, this can ultimately suppress your reproductive hormones and impair the ability of women to sustain a pregnancy.
12. Weight Gain
Countless studies have found that people who sleep less are more likely to be overweight. That’s probably because sleep deprivation messes with the hormones that regulate your appetite (ghrelin) and tell your brain you’re full (leptin), which can lead to chronic overeating.
13. Fat Gene Activation
Sleep loss basically turns your body against you: Research done on twins suggests that skimping on sleep (i.e., sleeping less than seven hours per night for the purposes of this study) fires up whatever fat-storing genes you have to increase your risk of gaining fat and holding on to it for good. We don’t want that, now do we?
14. Emotional Eating
In a recent study of 114 college students, participants were more likely to increase their food intake in response to strong feelings when they were particularly tired.
Sleep and depression are interrelated: Research suggests people who suffer from insomnia are more likely to suffer from major depression than people who sleep regularly.
16. Increased Risk Of Car Accidents
Sleep-deprived patients in simulators have just as many accidents as someone who is drunk due to loss of concentration, tired eyes and slower reflexes.
17. Slower Reaction Time
When your brain isn’t well rested, it doesn’t take in information, process it, and respond to it as quickly as usual. You lose speed before accuracy. You’ll get your work done, but it will take longer. Sounds familiar?
18. Premature Ageing
When you don’t get enough sleep, your body releases the stress hormone cortisol. If your body releases too much cortisol, it starts to break down collagen, a protein that promotes smooth skin and elasticity. Sleep deprivation also may decrease the production of the growth hormones in your body that strengthen the skin and fend off wrinkles, says Dr. David Bank, dermatologist and director of The Center for Dermatology, Cosmetic, and Laser Surgery in Mount Kisco, NY. Skimp on sleep and you’ll lose the restorative effects that make your skin look young and healthy.
19. Dry Skin
Sleep helps hydrate your skin so it doesn’t get all dry and flaky. In other words, adequate sleep is like a natural moisturizer.
20. Big-time Breakouts
When you don’t get enough sleep, your stress levels soar and your body responds by producing more of the hormone glucocorticoid. This disrupts your skin structure, which makes you more vulnerable to acne. Lack of sleep also triggers inflammation, which can makes small blemishes blow up.
21. Dull Skin
Sleep improves blood flow to the skin. Don’t get enough sleep, and your skin will look blotchy or pale.
22. Skin Sensitivity
Your body’s immune system builds its strength while you sleep, Dr. Bank explains. Sleep deprivation can make your skin more sensitive and even worsen existing skin conditions like rosacea or eczema.
Usually, 8 to 9 hours of sleep is recommended. So don’t over-work yourself, attempting to give up the exact same comfort you are trying to gain. Nothing is more precious than your health. As it is said,
A healthy mind is in a healthy body.
