Medical Video: How Your Cell Phone Is Destroying Your Sleep | Blue Light Sleep Effects
For some people who can't sleep in the dark, a bedroom light beam can help them sleep. However, it turns out it's not carelessly lights that you can use as a sleep buddy. Bedroom lights that emit blue light are thought to be more effective to help you sleep well. Is that right?
The bedroom lights that are glowing blue make sleeping better
The study published by PLoS One conducted research on two different groups to test the ideas above. One group was asked to sleep in a special room with blue light, while the others rested in a room lit by white light. Both groups also monitored their heart rate and brain activity during rest.
Afterwards, researchers found that people who slept in rooms with blue light bedroom lights seemed more relaxed and calm so that they fell asleep faster in just one minute. In contrast, participants who were asked to sleep in a white glow room took up to 3.5 minutes, even more, to finally fall asleep. The researchers concluded that yes, it is true that bedroom lights with blue lighting can make the mind relax rather than the other spectrum of colors.
Unfortunately…
Blue lights make it difficult for you to sleep at night
The above research was carried out during the day. In fact, wearing a bedroom lamp that is glowing blue makes you more difficult to sleep at night. This negative effect is related to how the biological clock works in your body, which is called the circadian rhythm.
Circadian rhythms work in response to changes in bright and dark light as the way the body says, "Hey, it's time you wake up!" And "Come on, now it's time for you to sleep". The dim atmosphere and cold weather at night will trigger the brain to release the hormone melatonin which makes you feel sleepy and relaxed, a sign of your time to sleep. Once the body is exposed to the morning sun (natural light), the body's biological clock will stop the production of this sleepy hormone maker and replace it with the hormone cortisol which makes you more alert and alert, ready to go through the day.
Well, the human body is found to be weakest against the spectrum of blue light, which is found in most bedroom lights. Blue rays emulate the nature of the sun's light so that the body's biological clock considers this light as a signal that it is still morning. Therefore, melatonin production stops and is quickly replaced with the hormone cortisol and other stress hormones because the body considers you still / already awake.
In short, bathed in the rays of blue light before bed instead makes you more energized so you need a longer time to be able to sleep. In fact, even after a good night's sleep, people who sleep with the lights on tend to be more difficult to get up early, slower, and easily drowsy all day.
Lack of sleep for long can have a negative impact on health
This change in sleep patterns then becomes a mess of the body's biological clock system, which will have a detrimental effect on health. This is because the body's biological clocks not only control our awareness and alertness but also regulate the "working hours" of every organ in the body.
Impaired circadian rhythms due to a decrease in melatonin levels in the body have been linked to risk factors for obesity, diabetes, heart disease, and several types of cancer, such as breast cancer and prostate cancer.
What should be done?
Train yourself to sleep with the lights off. The dim atmosphere and cold weather at night will trigger the brain to release the hormone melatonin and adenosine which makes you feel sleepy and relaxed, as a sign of your time to sleep. The more nights the more sleepy trigger hormones are released, making you sleep better and longer.
In addition, avoid using a laptop, watching TV, and / or playing cellphones before going to bed. You can also find blue light from the emission screen of your favorite gadget.
