Occasional sleepless nights are not harmful to you. However, insomnia is a sleep disorder which disturbs the sleeping habit of people during the night. And in the daytime, the person feels tired or fatigues. If someone is suffering from insomnia, he/she always (on a regular basis) faces problems while sleeping. One of the latest reports tells that about 40 million Americans experience insomnia every year. It is a proven fact that insomnia is one of the major sleep disorder in the United States.
Sometimes, a person might face issues while sleeping (sleeplessness) due to anxiety, stress, and their personal or professional issues. It lasts for a few days but this sleeplessness vanishes on its own without any medication or doctor’s concern. Normally, this is called acute insomnia. Insomnia comes in two forms: acute and chronic.
Chronic insomnia is slightly different from acute insomnia. When you face sleeplessness thrice in a week for at least three months, you might be experiencing serious insomnia. At that time, you need to go for medical intervention. However, it is also difficult to distinguish between acute and chronic insomnia.
