Sleeping With The Lights On

Everyone has difference of sleeping habits. Most of them are used to sleeping while listening to music, watching TV, or letting the lights in the room is brightly. They consider that it makes them fall asleep faster. They feel better when they sleep with the lights on. But actually, in my view, sleeping with the lights on is not good for our body’s health for several reasons.

One of the reason is that sleeping with the lights on can impact to our brain and our body. When we sleep at night, our body will rest, including our brain. It is important to make our body work effectively when we do activities again. If we sleep while letting the lights in the room is brightly, the light waves emitted by the equipment will be accepted by our senses of sight . The light waves can still penetrate the eyelids and received by retina and the lens of the eye. The brain will be stimulated to get back to work and process incoming information. Thus, our brain will feel tired and our body can not doing activities well.

Another reason is that sleeping with the lights on can obstruct  the production of melantonin. Melantonin is one of hormone in the immune system that can fight and prevent breast cancer. Unfortunately, the hormone melantonin will not be produced if we sleep at night with the lights on. The effect of the light cause the production of melantonin will be stopped. A biologist, Joan Roberts has did an experiment on animals. When the animals were given artificial light at night, the melantonin of their bodies would be decrease and their immune system would be reduce too. Other health practitioners , Lyne Edridge M.D who is the author of the book ‘Avoiding Cancer One Day at A Time ‘ also wrote that blind women eighty percent less likely to attacked by breast cancer than the average of other women. It is caused by their dark vision that can produced melantonin optimally, so that increased their immune system. Furthermore, considering that how important the melantonin is, we can change our sleeping habits from now.

The last reason is that children who sleep with the light on have a higher risk to attacked by leukimia. A conference on children suffering from leukemia was held in London, said that children who sleep with the light at night were more susceptible to leukemia than those who never used the light .This case shows that one of the causing leukimia is using the light on while sleeping.

   In the end, the habit of sleeping with the lights on can make negative effects for our body’s health. Because of the habit, our brain will feel tired easily and the production of melantonin will be obstructed. Beside that, children who sleep with the lights on can be a higher risk to attacked by leukimia. Therefore, turning off the lights when we sleep is one of  the good solution for us, or we can also use red or yellow bulbs if we afraid of the darkness.
