Effects of chronic insomnia; It is associated with serious health problems including diabetes, cardiovascular disease and hypertension. However, chronic insomnia also causes general irritability due to inability to focus, which comes with cognitive problems.

Chronic insomnia is also associated with obesity, making it more difficult to lose weight. Recent studies also show that the risk of neurological diseases such as Alzheimer's increases with insomnia.

Lack of sleep also complicates mental health problems. While insomnia that lasts for two to four weeks increases the risk of depression, lack of sleep affects depression treatment worse. That's why insomnia also makes it harder to get rid of depression.

To prevent insomnia from the very beginning, Posner suggested simple behavioral changes. For example, avoid falling asleep during the day or at least keep the naps short, even though it may seem unreasonable after a sleepless night. Just as pre-meal snacks reduce our appetite for food, naps longer than 20 minutes disturb our appetite for sleep.

Likewise, Posner disagrees with the idea that sleeping late on weekends or after a night out can make up for lost sleep. He stated that trying to make up for a bad night's sleep will only disrupt the person's daily rhythms.

Posner noted that we don't have to preserve our old sleep and wake times that might have been dictated by our need for a daily commute. He stated that we should apply the rhythm of the day even if it is at a different time than before.

Especially adolescents; Parents do not find it awkward to go to bed and wake up later than normal since they are in a different development process than adults and pre-adolescents.

After waking up, try to get some sunlight either by taking a walk or sitting by the window.

Following a regular schedule for meals and exercise as well as avoiding stimulants such as caffeine, nicotine and electronic devices for a few hours before bedtime helps for a regular sleep.

Finally, if you can't sleep, get out of bed. Do something relaxing - solve a puzzle or read something. Worrying about not being able to sleep makes the problem worse, so try to be distracted and use your bed only for sleep.
