People with sexual experience experience experience varying degrees of fatigue after sexual activity, such as eye fatigue, orbital dilation, blurring, insufficient vision, and insufficient vision. Sexual activity causes temporary fatigue in brain cells. The 12 pairs of Cranial nerves in the hair have 5 pairs of eyes, which are respectively responsible for vision, eyeball and eye muscle movement. Eye fatigue can affect the normal functioning of the nervous system, causing various discomfort such as head abnormalities and swelling. Muscle rigidity is a fundamental response to human sexual activity.
At the beginning of sexual activity, muscle sensitivity increases, followed by increased tension, ultimately developing into regular recurrent contractions or severe spasms of related muscle groups. The movement of Rectus abdominis muscle, gluteal muscles, deep pelvic muscles, and Muscles of respiration increased most significantly, and muscle rigidity of limbs was inevitable. The exercise of these muscle groups increases the release of metabolic products such as lactate, causing discomfort such as pain and numbness in muscle tissue. Therefore, in a short period of time after sexual activity, the motor and reaction abilities of the limbs muscles decrease, resulting in delayed movements. Car drivers need good vision, attention, and the ability to respond to unexpected events. Drivers who drive immediately after sexual intercourse may experience visual fatigue, lack of concentration, and decreased responsiveness. In the event of an accident or emergency, it is difficult to take effective measures in a timely manner, which can easily lead to traffic accidents. Ten traffic accidents in which drivers were primarily responsible were investigated, and four of them immediately drove after sexual activity. Therefore, high-risk activities such as car reinforcement, driving, high-altitude work, etc. should not be immediately engaged within one hour after sexual intercourse.
