Getting enough sleep is a vital part of a healthy and balanced life. It helps people process new ideas and keep their bodies working properly.
Even though you’re resting, your brain is still active. Sleep is a series of cycles that repeat several times throughout the night. During this process, the brain goes through two phases: non-REM and rapid eye movement sleep. Not getting enough sleep can affect your body.
Why is sleep important?
The various stages of sleep help ensure that the body and mind are completely rested. Some of these help you feel energetic and rested the next day, and others assist you in learning new information. Sleep is also important for the functioning of your immune system and metabolism. It can help you clear toxins from your body after you’ve been awake.
Not getting enough quality sleep can have detrimental effects on one’s long-term health. The CDC reported that many adults in the U.S. don’t get enough sleep each night. This issue could affect their ability to process information and learn new ideas.
The Body’s Internal Sleep Process
The 24-hour cycle of our bodies allows our bodies to release chemicals that encourage us to perform certain activities. One of the most common chemicals that are involved in the process is melatonin, which makes people feel drowsy. The level of this hormone increases in the evening, and it peaks in the morning, which helps us wake up refreshed.
The body’s natural response to external signals is known as the circadian rhythm, and it’s also found in animals, fungi, and plants. These rhythms control various activities, such as leaf movement and the feeding time of bees. In humans, the circadian rhythm is known to be responsible for regulating our sleep schedules.
The body then translates the time of day’s information into melatonin production, which helps maintain our sleep schedule. This process begins in the eye’s retina, where light signals are relayed to a region of the brain known as the suprachiasm.
The suprachiasmatic nucleus relays signals to other regions of the brain, which control temperature and hormones. These signals then travel to the pineal gland, which is a small organ in the brain that’s known to produce melatonin.
Unfortunately, when light is not activated in the morning, the signals to the pineal gland are not able to produce melatonin. This means that exposure to light can prevent the production of melatonin. This leads to a release of this hormone, which tells us to go to sleep.
Our bodies can determine when to start producing melatonin based on the signals sent by the brain. Melatonin is produced by taking in an amino acid known as tryptophan, which is taken from the bloodstream.
The process of melatonin synthesis involves a multistep process. The first step involves converting the amino acid into a 5-hydroxytryptophan. This happens through the action of an enzyme known as the tryptophan hydroxylase. Then, the brain chemical serotonin is added to the mix.
The two enzymes that are involved in the conversion of serotonin to melatonin are known as SNAT and HIOMT. These two enzymes start to perform their duties after dark.
The activity of SNAT determines the amount of melatonin that’s produced. Light exposure triggers the degradation of SNAT, which then travels to the pineal gland. At night, however, this enzyme is phosphorylated. This means that it’s able to maintain its function and increase production of melatonin.
When SNAT is degraded in the morning, the amount of melatonin drops, which makes one feel ready for the day.
What is the most powerful sleeping agent?
Melatonin is the most powerful sleeping agent. The body produces melatonin naturally, which signals to the brain that it’s time to sleep. Its levels naturally go up in the evening and then fall in the morning. Because of this, melatonin supplements are commonly used to help people get a better night’s sleep.
Why Do People Have Difficulties to Sleep?
Some of the causes of sleeplessness can include stress, aging, and habits that disrupt sleep. Other factors such as excessive pre-bedtime stimulation, a feeling of excitement, and noise can also affect a person’s sleep.
This can also be refered as insomia.
In most cases, insomnia is a type of sleep disorder that makes it hard for people to fall asleep or stay asleep. It can also cause them to wake up too early in the morning. Having this condition can affect a person’s mood and energy level, as well as their work performance.
What chemical is responsible for insomnia?
Lack of a certain chemical known as gamma aminobutyric acid, or GABA, can also cause insomnia. This substance is the brain’s brake fluid, and it decreases or stops nerve impulses’ transmission.
A study conducted on adults with chronic insomnia revealed that the level of this chemical decreased by 30 percent. It noted that this condition could lead to an imbalance of the brain’s activity.
What is the main chemical in sleep medicine?
There main chemicals found in Over-the-counter sleep aides may include various natural substances such as doxylamine, diphenhydramine, melatonin, valerian, and chamomile.
Some of the over-the-counter sleep aids that contain these active ingredients are Nytol, SomineX, Unisom, and ZzzQuil. Antihistamine drugs are commonly used for treating various conditions such as allergies and insomnia. They help people feel more sedated and relaxed by blocking the chemicals in their brain.
Risks for sleep aid medications
Sleep aid medications can cause various side effects. These include constipation, dry mouth, blurred vision, and urinary retention. Dr. Patel noted that elderly or older individuals who are taking these drugs might experience dizziness and confusion.
Many over-the-counter allergy and pseudoephedrine medications end in “D” or “Claritin-D.” These drugs can be dangerous for people with heart conditions, especially if they have been taking medication for long periods. The active ingredient of these drugs can affect the blood vessels in the body.
Some people may mistakenly believe that these drugs are helpful for treating insomnia. However, taking these drugs should be avoided. Doxylamine and diphenhydramine are antihistamines that are generally harmless for the heart.
Sleep aid pills often combine the active ingredients of other drugs. For instance, in Tylenol PM, diphenhydramine is used along with other drugs, such as acetaminophen, to help people get a good night’s sleep.
