Using a smartphone every evening before going to bed can affect health, especially the harmful effects of blue light.
Biorhythmia
circadian rhythm is the body's natural cycle, helping to regulate each person's sleep and wake time. However, if you are exposed to blue light from the phone screen every evening, it can disrupt your circadian rhythm, making it difficult for you to fall asleep and wake up tired.
Impact on sleep quality
Using the phone a lot before bed will reduce total sleep time as well as affect sleep quality. Some studies show that each hour of exposure to phone blue light before bed can increase the risk of insomnia by up to 59% and reduce sleep time by about 24 minutes.
Inhibiting melatonin production
Melatonin is known as the hormone that regulates sleep cycles. However, blue light from the phone screen can inhibit melatonin production, leading to difficulty falling asleep and not achieving good and deep sleep.
In addition, prolonged lack of sleep due to exposure to phone blue light can cause a number of other health problems such as memory loss, reduced concentration and especially increased risk of cardiovascular disease. Reversal
Therefore, to have quality sleep, limit the use of electronic devices before bed and create a comfortable, quiet sleeping space.
