7 Signs of Lack of Sleep

Feeling sleepy in spring and tired in autumn, and yawning all the time, is this what it means to be sleepy? Perhaps other manifestations in your life are reminding you that it’s time to make up for the sleep! Let’s take a look at 7 signs of lack of sleep that are easy to ignore.

1. Fall asleep quickly

Don’t think that yawning all the time means lack of sleep. Falling asleep as soon as you lie down or as soon as you touch the pillow may also be a sign. According to research reports, if you often fall asleep within 5 minutes of lying down, you may have severe sleep deprivation or even a sleep disorder. You might think this is a sign of good sleep, but the opposite is true.

2. Slow response

Making tea can also cause the tea to spill on your new clothes. Such clumsiness may be caused by lack of sleep. There is now a lot of evidence showing that people who lack sleep are slower in movement, have difficulty concentrating, have slow reactions, and have poorer motor skills. In addition, drowsiness can lead to impaired balance and depth perception.

If you miss your highway exit, forget to turn, or even suddenly forget you are driving, then you need more sleep. Of course, not all short selling is bad.

3. Emotional impulse

Lack of sleep can lead to mood swings. A study found that when we don't get enough sleep, we are more likely to feel unhappy because our tired brains store more negative memories. The behavioral manifestations of sleep-deprived people are very similar to those of people with depression.

Whether it's your craving for donuts that you normally wouldn't be interested in or your sudden willingness to spend on expensive clothing, lack of sleep may be the culprit. Lack of sleep can have a huge impact on the brain's prefrontal cortex, an area associated with judgment, impulse control, visual association and attention. Lack of sleep can lead to poor judgment and impulsive behavior, such as poor diet, buying things without considering the consequences, irritability and other emotional problems.

4. Impairment of expression

If you find yourself talking around proverbs and phrases like "A beggar can't be chooser" and "It's better to be safe than sorry," and you're not a retiree, it might be time to take a nap. The frontal lobe is associated with speech, constructive thinking and creativity and can be deeply affected by sleep deprivation. Experts believe that people who are sleep deprived find it difficult to have spontaneous complex speech, and many will have slurred speech, stutter, speak in a monotonous tone, or use clichés.

5. You tend to forget things

If you've ever gone out to mail something and realized you forgot it at home when you got there, or if you can't remember a new coworker's name even though you've heard it several times, lack of rest is likely to disrupt your memory. Harris said that sleep helps with memory consolidation and emotional processing. Without proper rest, it is difficult to form memories, and it is difficult to think carefully and act rationally without grasping the ins and outs.

6. Overeating

Multiple studies have shown that chronic sleep deprivation can disrupt blood sugar levels, causing the body to produce less leptin (a hormone that suppresses appetite) and more ghrelin (a hormone that stimulates appetite). These physiological changes inevitably lead to overeating. People who are tired are particularly fond of sweets and other simple carbohydrates, probably because these foods can quickly fill the stomach. In addition, lack of sleep will reduce self-control, and people will choose chocolate instead of carrots more often.

Experts say: "Leptin controls us to stop eating and produce a sense of fullness; growth hormone gives us hunger signals and tells us that we should eat. When sleep is insufficient, the balance between leptin and growth hormone is broken, leptin will decrease and growth hormone will increase. Therefore, without good sleep, the body's hormones will control us to eat more."

7. Read a sentence twice

Having trouble concentrating is also a sure sign that you’re not getting enough sleep. With lack of sleep, you lack focus and your ability to make split-second decisions is impaired, and studies have shown that sleep is important for decision-making, such as avoiding accidents while driving.
