Are you a person sleeping with lights on? If yes, you may want to rethink your habit. It may be an essential reason for many of the long-term health issues you face. Exposure to bright light during sleep may make it difficult for the brain to achieve deep sleep. The darker the room, the better one’s body relaxes and minimizes brain functioning. Hence, one should avoid regular exposure to bright lights during sleep hours. Maybe sometimes while napping, you might consider keeping the lights on. However, research says even napping needs a pleasant sleeping environment to give full effect afterward.
Moreover, some people keep their television on while sleeping. One can only imagine the effect. Thus watching a movie or a favorite TV show is not as relaxing as one thought it to be. Therefore, even if there is no sound or very minimal humming from the TV, the human brain processes the blue lights emitted out of it.
Side Effects Of Sleeping With Light On
Now that research could establish that one needs to switch off the light before sleeping. Keeping lights on while sleeping has a massive impact on human metabolism. Moreover, if a person is not getting proper sleep, his body deteriorates faster.
One major problem that may arise out of sleeplessness is depression. Blue lights emitted out of an electronic device may have detrimental effects on one’s mood. Thus a lack of sleep can make a person moody and irritable. Moreover, in the case of children, lack of proper sleep makes them unnecessarily hyperactive.
Another problem due to lack of proper sleep is obesity. This has been an issue in many countries. Food can indeed be an essential factor for obesity. However, there may be several other reasons. Depression itself may cause obesity.
Moreover, if lights interfere with sleep for very long, there can also be chronic illnesses such as high blood pressures, diabetes, heart diseases, etc. Furthermore, all these effects are interrelated. A person suffering from obesity is prone to diabetes and heart diseases.
Lastly, sleeplessness can affect one’s performance. Brain activity slows down when there is a lack of sleep. Therefore, a work may take a longer time for a person to complete as he loses concentration. Lack of attention may have more severe effects such as Accidents on the road. Thus a person needs to have a proper sleep before any long drive.
How Can Darkness Influence Sleep
The absence of light sends a signal to our brain that it’s time to rest. Melatonin is a hormone produced in one’s mind in the pineal gland. It is often also called the sleep hormone or even the darkness hormone. Melanin is the hormone that helps to signal the brain regarding sleep time. The hormone helps to prepare a body for sleep, thus making his muscles relax, influence drowsiness and drop in body temperature. The melatonin level is maximum during the evening and lowest during the day. Therefore, one should understand that sleep is a hormonal activity of the body. Similar to other things, this should also be a significant part of a person’s day. Avoiding it will just make situations worse.
