Sleep is for rest, but the effect of rest is not only determined by time, this is the term "sleep quality".

According to modern scientific research, people's sleep at night can be roughly divided into five to six cycles, of which the light sleep period and light sleep period occupying more than half of the time have little effect on relieving fatigue, and only the middle sleep period in the deep sleep state , Deep sleep and rapid eye movement sleep have a greater effect on relieving fatigue.

To improve the quality of sleep, the final thing to look at is the time of deep sleep.

The deep sleep state of normal people accounts for about a quarter of the sleep time.

I don't know if it was because it was too late and too tired or too fragrant, but Lin Xuan's sleep quality was very high that night.

Because of an accident that was so sweet and exciting to him, Xiao Nizi had to take a bath and change clothes again, and she probably realized it in the process of taking a bath—even if she didn't know about those things, it was really impossible for Lin Xuan not to knew……

This is by no means unintentional!
An angry Jiang Qianyu changed clothes for the third time in one night and started to settle accounts with Lin Xuan. After a long time of tossing, it was already past three o'clock in the morning when he went to sleep.

When Lin Xuan woke up, he didn't realize how long he had slept. He only knew that when he opened his eyes, he saw Xiao Nizi sleeping peacefully in his arms. He had never experienced the kind of happiness that filled his body and mind. Even thought of it.

Probably because the two of them had subconsciously adjusted their postures in their sleep, and the shoulders and arms that were being pillowed by her did not feel numb. I looked at the sky.

The curtains blocked the light, making it difficult to judge the time, and worried about waking up the little girl. Lin Xuan stretched his arms and struggled for a long time but couldn't reach the mobile phone on the bedside table. When he was trying to find a way, he suddenly heard a familiar voice. The piano melody rang in the room.

It was "Moonglow" by Xiaoni Bullet, which he specially recorded as the alarm clock.

Probably because her name is Qianqian, Xiao Nizi has been sleeping very lightly. When the alarm clock rang, Lin Xuan looked back at her, and sure enough, she had opened her eyes in a daze.

Now that she has woken up, Lin Xuan didn't have to worry about it any more. He quickly got up and picked up his mobile phone to turn off the alarm clock. By the way, he checked the time. The first time the alarm clock rang, it wasn't until seven o'clock, which means he just went to bed four hours.

At the same sleep time, he was full of energy. If he hadn't seen the time, he would almost have thought that he had slept until noon, but Xiao Nizi was still sleepy. Lin Xuan turned off the alarm clock and turned around to see that she had closed her eyes again.

Lin Xuan lay down again, tightened the quilt, and then stretched out her arms to hug her. Xiao Nizi raised her head, let his arms pass under her neck, stretched out her arms to hug him back, and fell into his arms again There was no movement.

Lin Xuan didn't want to understand why he slept so well, it was because he was sleeping with Xiao Nizi, or because of those deleted descriptions before going to bed, but soon found that sleeping well seemed to be troublesome.

This is the predicament that normal men have to face most mornings. Lin Xuan hugged Xiao Nizi and struggled for a while between indulging himself and letting her sleep peacefully.

The little girl who was lying quietly in her arms suddenly moved without warning, pulling some distance away from him, but her head was still on his chest, and she muttered softly: "I hate it!"

Lin Xuan caressed her still smooth and tender cheeks, and said with a smile, "Aren't you asleep?"

"Don't touch me."

Xiao Nizi twisted her body again, and put it in a comfortable position again between his shoulders and neck. Lin Xuan wanted to laugh seeing the two still embracing each other, but she could tell that she was really sleepy. So instead of playing tricks on her at this time, he nodded seriously, "Yeah."

Jiang Qianyu soon fell into a deep sleep. Lin Xuan heard her slow and long breathing, and the faint snoring sound like a cat. He couldn't help showing a little smile on his face, so he didn't do anything else, hugged her, I don't know when, and I slowly fell asleep.

The darkness is endless.

Time seems to stand still here too.

Lin Xuan was awakened by a very gentle itching. When he opened his eyes in a daze, he happened to see the little girl who was close at hand quickly closed her eyes. Yan and slowly receded.

The shoulders under Xiao Nizi's pillow were a little numb. Lin Xuan moved his arm slightly, and Xiao Nizi moved her head to his chest, raised her face to look at him, and asked with big eyes blinking. : "Are your shoulders sore?"

"A bit."

Lin Xuan slowly moved his shoulders to drain the blood, then put his arms around her and asked, "What time is it?"

"I don't know, just take a look."

Lin Xuan took a look at the phone and said, "It's almost ten o'clock, are you hungry?"

Xiao Nizi shook her head, "Not hungry, how about you?"

"I'm not hungry either."

Lin Xuan smiled, hugged her and closed his eyes, "Sleep again."

Xiao Nizi didn't make a sound, wondering if she was playing a boring heartbeat game. Lin Xuan stroked her soft and long hair and didn't speak. This quiet and warm feeling was good at first, and it made him feel It was full and warm, but after a few minutes, I felt that it was actually not bad like last night.

He hugged Jiang Qianyu up, Xiao Nizi closed her eyes, she seemed to be asleep again, and didn't respond, Lin Xuan slowly moved closer.

It was almost noon, the bright sunlight outside was blocked by thick curtains, and the light in the room without the lights still looked very dim.

The sunlight outside the room moved horizontally, and the room was chirping and chirping. When Xiao Nizi pushed Lin Xuan away from the corner of the bed, and finally realized that he was very hungry, Lin Xuan checked the time with his mobile phone, couldn't help being stunned for a moment, and then Turning to look at her with a strange expression, "What time do you have class in the afternoon?"

"02:30, what's the matter?"

Seeing his expression, Xiao Nizi crawled over on both hands and feet, stretched her head to look at the phone screen, and screamed "ah" involuntarily, "It's two o'clock——"

She jumped out of bed with bare feet like her tail was on fire, subconsciously ran to the bathroom, came back halfway through the run, grabbed the pillow and threw it at Lin Xuan, "It's all your fault! It's all your fault! Ahhhhhhhh Ah, I'm going to be late-"

She beat the pillow a few times bitterly, and hurried to the bathroom to wash up. Lin Xuan checked it several times with his mobile phone in disbelief. Seeing that it was really two o'clock in the afternoon, he touched it. Count with your chin.

It seemed like I went to bed after nine o'clock last night, and by two o'clock in the afternoon...

More than two hours last night, fourteen hours today, added together...

sixteen hours?
Ok……

Not a loss.

After getting out of bed and opening the curtains, the dazzling sunlight flooded into the room, making Lin Xuan unable to open his eyes. It took him a while to get used to the sunlight. He stepped on his slippers and went to the living room, opened the refrigerator, and then went to the kitchen to open it again. Check the refrigerator, then walked back to Xiaonizi's room with her slippers on, took her mobile phone to take a taxi, and asked, "Don't worry, there is still time, there are leftovers from last night in the refrigerator, and a small bowl of rice, which can be heated in the microwave one time……"

"Don't talk to me, I don't want to talk to you!"

"If you don't want to eat, the Shengjian restaurant next door should still be open, or KFC, and you can have a meal for 5 or 7 minutes. This time period will not be too congested. Take a taxi to the school for a maximum of six to seven minutes... Counting your time from The time from the school gate to the classroom is too late."

"Don't talk to me, I don't want to talk to you."

"If you take too long to wash and change clothes, it's really not good. You still have bread and yogurt, put them on first, and I'll cook something delicious for you at night."

"Don't talk to me, I don't want to talk to you."

"Then I've booked a car."

"Don't talk to me, I don't want to talk to you."

"What class are you in? I'll get you the book first."

"Don't talk to you, I don't want to talk to you... math."

"Tsk, it smells so good."
