Some
people afraid of the dark, usually love to sleep with the light, there are also
some people used to spend long night with lights, because they work at night
and involuntarily, some people even prefer the night life under the light.
However, it will bring various injuries to our body.
1.
Increased
risk of cancer
Miss Martin of 24 years old, due to opened a
shop on her house. She often fall asleep in lights and noisy, gradually develop
a "with light sleep" habit. Many friends have told her that this is a
bad habit, "easy to get cancer.". "Will get cancer" this
argument let sleep with the light from childhood of the Miss Martin surprised.
In fact, "with light sleep" does have evidence that may be
carcinogenic.As night fell, a variety of complex light will make people's
natural circadian rhythms into a state of confusion. While also inhibiting
pineal gland normal secretes melatonin at night. Medical studies have found
that normal body will produce approximately 400 tumor cells daily, Inhibiting
Lesions by the body's immune system. Once no melatonin, then the body's immune
system will decrease, growth of cancer cells and cancer cells damage to DNA
will accelerate the pace. As an antioxidant, melatonin can effectively protect
DNA from oxidative damage. However, once destroyed, DNA mutation may occur, and
even serious there could be cancerous.
2.
Cause
Precocious Puberty
Human hormone secretion have circadian
rhythms, Such as androgen will reached its highest point at seven or eight a
clock on morning. According to hospital experts, clinically, there are many
kids who get use in found sleep with the light, or for a long time playing
computer, or receive excessive light are prone to precocious. This is because
the light exposure is too long, so that reduce the secretion of melatonin. Sleep
disorders may cause the secretion of follicle-stimulating hormone in advance,
which will led to early development of precocious puberty or sex organs.

Easy to
make people’s eyes diseases
Recently
the University of Pennsylvania School of Medicine and Children Hospital
conducted health survey for 479 children whose aged 2 to 16, found that
respondents in the first 2 years if he sleep in a dark room, when they grow up
the proportion of myopia is 10%. If they sleep in a room with small
night light before aged 2, the proportion of myopia is 34%. If
they sleep in a room lit headlights, the proportion of myopia is 55%. There are
studies indicate, A person work and live in the white light or lantern polluted
environment to for a long time, in addition to myopia, the incidence of
cataracts are more than 40%.
4.
Long-term
no sleep until midnight will easier cancered.
Medical research found that people who work at night,
has a higher risk of suffering from breast cancer and prostate cancer. Medical
researchers also believe that when you urinate suddenly turn on strong light
lamp, or in a dark place suddenly exposed to strong light will affect sensitive
biological clock. So you’d best not to suddenly turn on headlights when
urinate, be preferable to use only the glimmering night light illumination.
