Sleep time: The total sleep time is less than 6 hours, or the sleep time is more than 30 minutes.
Sleep quality: When you wake up at night, you can’t continue to fall asleep, or you wake up more than an hour earlier than normal. This happens 3-4 times a week, which is a chronic state.
Daytime functional limitations: No matter how much you sleep at night, you will feel sleepy and tired during the day.
If the above conditions persist for more than 3 months, it is called chronic insomnia and is in a disease state. Also, the above time standards are for most adults. Minors generally sleep longer, and the elderly will sleep short. The elderly may generally sleep for 5 hours, and even some elderly sleep only 4 hours at night, plus a nap during the day is enough. These are within the normal range, but that doesn’t necessarily mean you have to get 8 hours of sleep, but most people still have to get at least 6 hours. However, the standard of care is for the majority of people, and a few people will inevitably have special circumstances.
Now US research shows: some successful celebrities, such as Einstein and Lincoln. They can guarantee a deep sleep for a short period of time, leading to a better rest period. They are such people themselves, who barely have time to sleep every day, four hours at night is enough, but are full of energy and bright minds during the day. So in a sense, they can do twice as much in their lifetime as we do.
However, here we want to remind everyone that there are very few people with short sleep genes, most people still need to sleep 6-8 hours, don’t blindly imitate them.
One might ask: Can I wear some smartwatches to monitor my sleep and assess the quality of my sleep? The quality of sleep is actually very difficult to judge, either I didn’t have a dream today, or I slept well, and we can judge from a new perspective to be in a good state.
The first is the mental state during the day. The core of evaluating sleep quality is the mental state during the day. It doesn’t matter what time you go to bed at night, how many times you wake up at night, whether you’re dreaming, whether you’ve slept 6 or 8 hours (of course these also matter), the most important thing is how you feel during the day.
For example, some people who sleep snoring are medically called sleep apnea syndrome. They may sleep until dawn and feel sleepy during the day. Because snoring is easy to cause the risk of suffocation, it is easy to wake people up, so the quality of sleep will be particularly poor.
The second is to calculate the sleep efficiency. For example, if you start lying in bed at 12:00, you actually fall asleep at 2:00 in the middle of the night, wake up at 6:00 in the morning, and stay in bed until 8:00. Although I was in bed for 8 hours, I actually only slept 4 hours, so my sleep efficiency was only 50%.
Electrical adjustable bed option for sound sleeping. Nowadays, there are options of adjustable bed manufacturers in the market providing comfortable sleeping experience available.
The advantage of the intelligent electric bed is that it can lift the mattress, with a fine adjustment range of 1°, which can realize the silent lifting of the back up to 60° and the leg up to 40°, and has FLAT, zero gravity, movie viewing, Watching, reading, anti-snoring, nursing and waking up are eight comfortable modes, you can understand your needs in seconds and adjust with one click. Here are a few modes that I like to share with you.
First, look at this FLAT mode. This mode will keep the normal lying state when you get out of bed, which is the most common appearance of our daily bed. It is very suitable for lying down and sleeping deeply at night. Fits the curve of your spine and provides comfortable support to improve sleep quality.
Nowadays, many young people have a slight snoring phenomenon when sleeping. In fact, the main reason is that the sleeping position is not suitable, that is, the head is too low, which leads to poor breathing. Using the anti-snoring mode can slightly raise your back by about 15°, so that the Keep your head in the side sleeping state, fully open the airway, ensure smooth breathing during sleep, reduce snoring and not disturb your sweet dreams.
The most comfortable I think is the movie viewing mode. In this mode, your back will be raised 45° and your legs will be raised 15°, just like watching a movie on a movie theater seat, and there is no need to put a pillow behind your back. Improve the comfort of your reclining, and you can easily enjoy the leisure time of watching movies at home.
Conclusion: Everyone dreams, but if the dream period is too long or too many, it is not normal. If you don’t have a dream when you wake up and don’t remember what the dream was about, you may think you’re not dreaming. If you wake up in a dream, you will remember the dream just now, so dreaming does not mean that you have not slept well.
