Take the electronic devices from the bedrooms and make the room as dark as possible at night to avoid the risk of various diseases such as cancer, say researchers, reports British newspaper The Daily Mail.
Remove all sources of artificial light during sleep to stop the harmful effects on our biological rhythm which is associated with diseases such as cancer, diabetes, depression and obesity.
A scientist who studies breast cancer Richard Stevens says that we must begin to appreciate the dark environment because even light congestion in the household at night helps the brain and body to prepare for sleep.
– As deep sleep is needed for our well-being, it is the exposure of the dark at night. The importance of sleep finally came in a big way in thinking and practice, but the importance of shading is still greatly underestimated – says Stevens.
Stevens, The University of Connecticut, says that our biorhythm is developed to monitor daily pattern of sunlight and the pattern followed and the secretion of hormones, genes work, body temperature and metabolism. Artificial lighting in turn can cause disturbances.
With the use of light bullet-proof shutters Stevens points out that you should remove all devices that emit blue light from the bedroom because they keep us awake. If you need to get up during the night, then we need to use lights with tinted red bulbs which cause least disturbances.
In a paper published in the journal Philosophical Transactions B Stevens warns of the harmful effects of artificial street and home lighting.
– Excessive lighting the night sky is an important issue such as climate change – Stevens points out, adding that the negative effects of artificial lighting on the especially vulnerable children, including unborn babies.
It is believed, for example, that artificial lighting disrupts the secretion of melatonin, which prevents the appearance of breast tumors.
Studies have shown that women who work at night are exposed to a higher risk of developing breast cancer and night working hours are associated with increased risk of prostate cancer or bowel. Other studies have indicated a possible link between artificial lighting during the night and the occurrence of diabetes, depression and obesity.
