Why do we dream repeatedly?
There is a period in sleep called rapid eye movement (REM). When the body is in the most active state, breathing and heart rate will become faster, and we are also prone to dreaming. At this stage, our brain activity will be as high as when we are awake, or even higher.
During the rapid eye movement phase, our eyes will also move back and forth quickly on the track.
The following situations may cause you to dream repeatedly:
Excessive stress: excessive stress in work, study and interpersonal relationships may lead to repeated dreams;
Anxiety and depression: anxiety and depression may also lead to repeated dreams;
Physical discomfort or disease: some physical discomfort or diseases, such as stomachache, headache, heart disease, etc. It may also lead to repeated dreams.

These sleep phenomena
Or a "distress signal" sent by the body.
During sleep, sometimes we will experience some unpleasant dreams, such as repeated nightmares, physical pain or injury in dreams. These phenomena may be that the body is sending out a distress signal, suggesting that there may be some health problems.
Repeated nightmares usually mean that our mental state is unstable.
Long-term stress, anxiety, depression and other emotions will affect the quality of sleep, making us prone to nightmares.
If there is physical pain or injury in the dream, it may be that the body is sending out a distress signal.
In this case, we may need to check whether there is something wrong with our health.
I suddenly wake up and feel my heart beat faster or my breath is short. Or maybe your body is asking for help.
This phenomenon often happens in the dream when there is an emergency or serious physical problems, and our body will automatically produce this reaction.

What effect can poor sleep bring to the body?
1. Deafness and tinnitus
Lack of sleep can easily lead to insufficient blood supply to the inner ear and damage hearing, and staying up late for a long time may lead to deafness.
2. Obesity
People who stay up late often eat "midnight snack", which is not only difficult to digest, but also leads to loss of appetite the next morning, resulting in unbalanced nutrition, obesity or fatty liver.
3. Skin damage
The skin entered the maintenance state from 10 pm to 1 1 pm. If you stay up late for a long time, people's endocrine and nervous system will be out of balance, making the skin dry, elastic, dull and dull, resulting in problems such as acne, acne and dark spots.
4. Memory loss
The sympathetic nerves of those who stay up all night remain excited at night, and during the day, there will be listlessness, dizziness, memory loss, inattention and unresponsiveness.
After a long time, there will be problems such as neurasthenia and insomnia.
5. Gastrointestinal crisis
Human gastric mucosal epithelial cells are updated every 2 to 3 days on average, usually at night. If you eat at night, the gastrointestinal tract will not rest, which will affect its repair process.
At the same time, supper stays in the stomach for a long time, which promotes the secretion of gastric juice and stimulates the gastric mucosa. Over time, it is easy to cause gastric mucosal erosion and ulcer.
6. Decreased immunity
Often in a state of staying up late, fatigue and listlessness, the body's immunity will decline, and colds and allergies will occur. I'll meet you unexpectedly.
7. Heart disease risk
People who have been "black and white upside down" for a long time not only have a bad temper, but also their internal organs are not adjusted in time, which will increase the risk of heart disease.

pay attention to
Long-term insomnia is not conducive to physical health and emotional management. If you still have insomnia after the above adjustments, it is recommended to go to the hospital.

What is the correct sleeping position?
Recommended sleeping position: lying on the right side and supine.
Lying on the right side and supine (feet are naturally shoulder-width apart), these two sleeping positions are suitable for most people without physical illness.
Of course, this is just a foundation. If you want to better protect your spine or if you have waist or leg discomfort, we need to use some items.
When lying on the right, be sure to pay attention to the height of the pillow. Pillows should be shoulder-high. Don't tilt your head, put your head in a neutral position, so that our whole neck and shoulder muscles will be more relaxed and more labor-saving.
We can also put a thin cushion between our knees to keep our pelvis in a neutral position, so that we won't cross our legs when we sleep and avoid excessive distortion.
When lying flat, you can put a cushion in the bent position such as neck, waist and knee popliteal fossa, which can better support the bending and make our muscles more relaxed.

Avoid three wrong sleeping positions
1. Eight steps outside the foot
When our feet do the external eight movements completely, the waist will bow and the thigh bone will rotate outward, which will lead to backache after a long time.

Excessive curl
When we curl up too much and can't sleep, our backs will be arched, and the muscles in our backs will be overstretched and unable to relax, which is not good for our thoracic vertebrae, lumbar vertebrae, cervical vertebrae and even the whole spine.
Sleep on your stomach
When sleeping on our stomach, our heads will lean to one side, which will make our cervical vertebrae and upper thoracic vertebrae in a twisted state.
This sleeping position is unhealthy for our spine.
In addition, when we sleep on our stomach, there will be problems in breathing, including some oppression on the heart and lungs, which will affect the heart and lung function.
