Insomnia is a condition where someone finds it difficult to fall asleep or stay asleep. The ailment could either be acute or chronic, and it could also come and go. Acute insomnia may last for several weeks or only one night. When it happens at least three nights a week for three months or more, it is considered chronic insomnia.

How Deep Sleep Do You Need at night?

Different amount of time is spent in deep sleep by different people depending on their age because children spend more time in deep sleep than adults. In general, children and teenagers who are in school need to sleep for about 20 to 25 percent of their time in deep sleep, while adults should experience deep sleep for 16–20% at the night. According to studies, as people age, they spend less time in deep sleep, and men usually have a decrease in deep sleep than women as they age.

Health Benefits of Deep Sleep you don’t know about

During deep sleep, the body releases growth hormones. The body releases growth hormones during deep sleep, and this substance aids in tissue growth and repair. The growth hormone is essential for the development of children, and it also plays a role in adult bodies by helping to build muscle after exercise. It also helps to limit the effects of normal wear and tear on the body. This action occurs because of the increased blood flow to the muscles that happen during deep sleep.

The removal of waste from the brain, such as the protein beta-amyloid, which is present in abnormally high concentrations in the brains of Alzheimer's patients, may also be aided by deep sleep. Your brain can process and store memories more easily if this waste is removed. Deep sleep also restores your immune system and makes it function better, by re-energizing the body cells.

Risks Associated With Lack of Deep Sleep

It is evident that not getting enough sleep is hazardous for your health. Overall sleep quality suffers when you don't get enough deep sleep. Your body and brain may be affected by the following: 

1. Pain:

Lack of quality sleep can aggravate chronic pain. This could manifest in several ways. It might even result in a fibromyalgia diagnosis, which is marked by pain, despair, and exhaustion. But when you have a deep sleep, you’ll experience less pain.

2.  Impaired Growth:

There will be less deep sleep for kids with untreated sleep disorders including sleep apnea, and the release of growth hormones is hampered by less deep sleep. This results in less rapid growth for children, but once their sleep issue is treated; kids may make up for the lost growth.

3.  Dementia:

Alzheimer's patient’s brain tissue usually develops beta-amyloid plaques. And lack of deep sleep might obstruct the removal of these proteins which might hasten the disease's progression.

4.  Immune Function and Chronic Diseases:

Your immune system may be affected by a lack of deep sleep. Lack of deep sleep might make you experience more common ailments like the flu or the common cold (flu), and your chances of getting chronic illnesses like cancer or heart disease may also increase if you don't get enough deep sleep.

Insomnia: Although the exact cause of insomnia is not exactly known, stress, anxiety, and bad sleeping conditions like an uncomfortable bed or a room that is unnecessarily loud, noisy, hot, or cold are frequently linked to it. Insomnia can also result because of lifestyle choices like jet lag, shift work, or consuming alcohol or caffeine right before bed.

Types of Insomnia:-

Insomnia comes in two types namely, primary and secondary. Primary insomnia is a term used to describe sleep issues that are unrelated to any other medical conditions or issues. While the term "secondary insomnia" refers to sleep problems brought on by a medical condition (such as asthma, depression, arthritis, cancer, or heartburn), pain medicine, or drug usage (like alcohol).

Causes of insomnia include:

• Stress results from major life events like a job loss or change, a loved one's death, a divorce, or a move.
• Environmental factors such as temperature, light, or sound.
• Modifications to your sleep routine, such as jet lag, a new shift at work, or negative habits you acquired when you previously struggled with sleep.
• When anxiety and depression set in.
