About 70% of sleep problems
In this survey (500 men and women nationwide), 367 people, 73.4% of the total, answered that they were dissatisfied with their sleep. Here are the specific complaints (multiple answers allowed).
sleep troubles“Waking up in the middle of the night” was the most common at 42%, followed by “I can’t get rid of fatigue” at 39.2%, and “I can’t sleep and it’s hard to wake up in the morning” at 36.5%.
Young people who wake up in the middle of the night or have trouble falling asleep often have problems with their lifestyle. If you feel tired, have difficulty getting up in the morning, or feel sleepy during the day, it is likely that you are lacking sleep. If symptoms persist even after changing your lifestyle and sleep schedule, see a doctor.
Elderly people who “wake up in the middle of the night” or “wake up too early and can’t sleep afterwards” may be due to aging. If you feel uncomfortable during the day, please consult a sleep specialist medical institution.
things to do before going to bed
Next, I would like to introduce the results of the questionnaire “What do you do before going to bed?” (multiple answers allowed).

Only 7.4% of the respondents answered that they did not do it before going to bed.
〇The reason why I ca
n’t help but look at my smartphone is… ・I can’t help but play with my smartphone because it’s my only time (woman in her 30s)
. When I get a notification, I see it (woman in her 20s)
・I can’t sleep when I look at my smartphone, but I can’t sleep without fiddling with my smartphone (woman in my 40s)
Before going to bed, I watch smartphones, TV, distributed videos, games, Looking at the computer reduces sleepiness, and the quality of falling asleep and sleep deteriorates. This is because the blue light emitted from electronic screens reduces the secretion of the sleep hormone melatonin.
If possible, try not to look at the screen 30 minutes before entering the futon. If you have difficulty, please use glasses or film that cuts blue light. If you stop looking at your smartphone before going to sleep and look at it after waking up in the morning, you will be able to fall asleep better and wake up refreshed.
What are you doing on your smartphone before going to bed?
So what exactly do people who have become accustomed to using their smartphones before going to bed do? Next, we will introduce the results of the questionnaire on “What do you do with your smartphone before going to bed?” (multiple answers allowed).
Things to do on your smartphone before bed“Watching/posting on social media” was the most common response at 51.1%, followed by “watching videos” at 37.2% and “playing games” at 17.6%.
Videos are more likely to stimulate the brain than static images such as text, and are thought to have a greater negative effect on sleep. Also, be aware that blue light is more likely to enter your eyes when you look at your smartphone in a dark place than when you look at it in a bright place.
Is it dangerous to use your smartphone before going to bed?
Finally, we will introduce the results of the questionnaire on “How much do you use your smartphone before going to bed?”
Smartphone usage timeIf possible, avoid looking at your smartphone before going to bed. The sensitivity to blue light varies greatly from person to person, so it is not possible to set a fixed amount of time. This is because the longer you are exposed to blue light, the less melatonin, the sleep hormone.
If you look at your smartphone before going to bed, use glasses or films that block blue light. You should also set your smartphone to cut blue light.
