Sleep Knowledge - Test your Sleep IQ

You who sleep every day, how much do you know about sleep? The National Sleep Foundation recently designed a "Sleep Quotient" quiz. The title is true or false, one point for correct answer. Let’s try it out!

(1) During sleep, the brain is resting.

Error. The brain is still very active during sleep, preparing for the next day's awakening and optimal state.

(2) If the sleep time is less than the required amount of 1-2 hours, the next day's actions will always be affected.

Correct. Adults need 8 hours of sleep a day to stay energetic. How can I know the amount of sleep I need? The method is very simple, do not set the alarm clock before going to bed, and wake up naturally. This is the amount of sleep you need.

(3) Boredom can cause drowsiness.

Error. People feel sleepy when they are bored. However, what really causes drowsiness is lack of sleep. Boredom does not cause drowsiness, it just makes drowsiness more obvious.

(4) Lying in bed and closing your eyes to rest your mind does not satisfy the need for sleep.

Correct. If there is not enough sleep, the body will accumulate "sleep debt", and sooner or later it will have to pay for it.

(5) Snoring is not harmful as long as it does not wake up oneself or affect others.

Error. Snoring represents a sleep disorder that threatens your health. Ninety percent of people who snore may suffer from sleep apnea, which may increase the risk of cardiovascular disease and high blood pressure.

(6) People dream every night.

Correct. Although many people wake up from sleep, they don't think they have ever dreamed. But in fact everyone dreams every night.

(7) The older you are, the less time you need to sleep.

Error. The amount of sleep required in adulthood does not change much. The amount of sleep required in old age does not decrease compared to when young, but sleep less at night and more sleep during the day. Although sleep difficulties are common in the elderly, age is not the main cause. If you have poor sleep habits or health problems that cause sleep difficulties, it is recommended to consult a specialist.

(8) Most people cannot tell when they will fall asleep.

Correct. Most sleep studies point out that people do not know exactly when they will fall asleep. So when you feel tired while driving, even if you are only a few kilometers away from your destination, don't think you can definitely survive it.

(9) When driving, turning up the volume of music can help keep you awake.

Error. If you feel unable to stay awake while driving, the best stopgap measure is to park in a safe place for a nap or have a cup of coffee. But the most effective solution is to get enough rest before setting off.

(10) Sleep disturbances are mainly caused by anxiety and psychological disturbances.

Error. Sleep disorders are caused by many factors, including: environment, diet, disease, and psychology. Worry and psychological barriers are just one of them.

(11) The human body cannot fully adapt to night shift work.

Correct. All organisms have a menstrual cycle, also known as a 24-hour rhythm. This will affect the replacement of our sleep and wakefulness. When crossing time zones, you must adjust your circadian rhythm according to the changes in the day and night. While on the night shift, the objective day and night turnover has not changed, so its circadian rhythm cannot be adjusted.

(12) Insomnia can be cured without treatment.

Error. If you don't pay attention to it properly, sleep disorders will not disappear automatically, and allowing them to develop will only reduce the quality of life.
