What are the adverse effects of turning on the light when sleeping

Many babies actually sleep in a relatively bright environment at night. In particular, parents will turn on the lights when they sleep so that they can get up at night to take care of their babies. In fact, such behavior habits are not conducive to the healthy development of babies. So below we will analyze the impact of babies sleeping with the lights on. We hope that every parent should pay attention to these issues.

Sleeping with the lights on is not only a waste of energy, but also affects the quality of sleep. Human biological rhythms, including the biological clock, are naturally formed in the process of humans adapting to the environment, and "sleeping after dark" is a normal part of human life. If you break this routine and sleep with the lights on at night or sleep under strong sunlight, it will cause the body to produce a kind of "light stress", which will affect the body's normal metabolic functions, including normal physiological and biochemical reactions in the body, and even cause abnormal heartbeat, pulse, and blood pressure, leading to disease.

Recently, medical researchers have confirmed that turning on the lights when going to bed will inhibit the secretion of a substance called melatonin in the human body, thereby reducing the body's immune function. People who often work night shifts, such as flight attendants, telecommunications workers, doctors, nurses, etc., have a cancer incidence rate twice as high as normal people. Medical experts warn that sleeping with the lights on not only affects the body's immunity, but also makes it more likely to get cancer.

It is especially bad for babies and young children to sleep with the lights on. Any artificial light source will produce a very subtle light pressure. The long-term existence of this light pressure will make people, especially infants and young children, become restless and upset, making it difficult to fall asleep and having poor sleep quality. At the same time, letting infants and young children sleep under the light for a long time will further affect their ocular reticular activation system, shortening their sleep time each time, making their sleep shallower and easier to wake up. If a baby sleeps under the light for a long time, it will be very detrimental to the child's vision development. If the eyes are exposed to light for a long time while sleeping, the light will continue to stimulate the eyes, and the eyeballs and ciliary muscles will not get enough rest. This can easily cause damage to the retina for infants and young children, affecting the normal development of their vision.

Although this is a small behavioral habit, it is actually very detrimental to the baby's healthy development. Therefore, in order for the baby to grow up healthily, parents should pay more attention to these health care common sense and try not to turn on the lights when sleeping at night, so as to help the baby have a good sleep.
