Sex can have a positive impact on diseases in the joints, blood vessels, heart and stomach. You can even turn to your sexual partner for help with headaches. The reason is simple: changes in hormones in the body during sex help reduce pain.

Expert advice: People with rich imaginations can imagine sex. Dr. Peter Staats of a hospital in Baltimore conducted an experiment on a group of college students in the hospital. He asked the college students to put their hands into cold water until the pain was unbearable before taking their hands out.

But if they put their hands in the water and imagined something beautiful to distract their attention, the college students who imagined sex spent their hands in the ice water twice as long as the others. Dr. Staats believes that pain sensations are governed rationally because the same areas of the brain "radiate" emotion and pain. If a patient imagines himself racing in a car race, he will forget all about the pain.

What makes women excited is that sexual imagination can also help lose weight. When ladies can't help but want to eat snacks, they might as well think about sex. When their minds are filled with sexual imagination, snacks that can make people fat will naturally be left behind.

Sexual fantasies are normal behavior

When people are in a clear state, they imagine sexual processes or sexually colored situations and often occur simultaneously with actual sexual behaviors such as masturbation, which is called sexual imagination. After entering a state of loose consciousness, people gradually focus on sexually colored imaginations, which are called sexual fantasies, also known as daydreams. Sex dreams are sexual relations in dreams. The sexual objects in sex dreams are generally changeable, with no fixed rules, or the content is absurd and the plot is disordered.

Having sexual desire is a normal physiological and psychological phenomenon. It is normal human behavior to have sexual intercourse, masturbation and other healthy sexual behaviors in compliance with social norms. Similarly, sexual imagination, fantasy, and sexual dreams should also be considered normal behavior. They are a form of masturbation by the brain. They are just for the purpose of venting sexual energy through sexual fantasies or dreams and gaining some satisfaction. No need to make a fuss. However, if you are overly dependent on this way of venting your sexual desire and form a hobby, it is considered pathological, such as phantomism and dream philia. For patients with phantomism and dream philia, in addition to persuasion, patients should also be guided and helped to clear the normal outlet for sexual desire, such as guiding patients to fall in love and get married and provide marriage guidance. It is also a good way to divert and sublimate the patient's attention to sexual desire and sexual content, requiring the patient to devote himself to study or career and seek a positive lifestyle.

Every night during the "rapid eye movement period", the human body will enter a state of sexual excitement 4-5 times, and blood will flow to the sexual organs. Men will have erect penises, and women will have vaginal moistness. At this time, people tend to have sex dreams, which usually last 20-25 minutes. Moreover, women are more likely to have sexual content in their dreams during their menstrual period.

In fact, it is not an accident that people can feel sexual pleasure in their sleep. Sexual excitement at night has the following effects on the human body itself:

1. The human body is performing self-examination and maintenance of various organ and system functions;

2. Orgasm in sleep can help people get rid of the mental stress caused during the day;

3. Sex dreams are a kind of compensation for not getting sexual satisfaction in real life.

So, don’t feel guilty if you have sex dreams, it is a sign of health. Surveys show that 70% of women and 80% of men often have sex scenes in their dreams.

Sexual dreams can be "designed" and "predetermined", which requires the dreamer to be in a semi-dream and semi-awake state for a long time. At this time, the brain will hazily produce vision and hearing hallucinations, and the appearance of the hero and heroine will gradually appear, combined with the experiences of one's acquaintances, relatives and friends.

However, if you want to have healthy sex dreams, the condition is: indulge yourself in sexual fantasies. If you suppress your sexual fantasies too much for a long time, you will only have nightmares.

However, if the same sexual dream repeats every night, it should also cause alarm and it is best to go to a doctor for treatment. This may be a precursor to a serious illness.
