In our article, we will introduce you to the main points related to the action of this unique hormone, and also look at how you can optimize your sleep with its help.
The role of melatonin in somnology
What is melatonin: definition and functions
Melatonin is a hormone produced by the pineal gland in the brain. It plays a key role in regulating circadian rhythm, a natural, internal process that regulates the sleep-wake cycle and repeats approximately every 24 hours. Melatonin also helps control the temporal phases of various physiological functions such as blood pressure and body temperature.
Interaction between melatonin and circadian rhythms
Circadian rhythms affect the body’s melatonin levels, which rise as darkness sets in, preparing the body for sleep, and decrease as light comes in, helping to wake up. This interaction supports a stable and healthy sleep cycle. Disturbances in these rhythms can lead to insomnia and other sleep disorders.
Melatonin and its effect on the sleep-wake cycle
Regulating the sleep cycle: the beginning and end of the process
The process of sleep control begins with the perception of light by the eyes and its transmission to the deep structures of the brain, after which the pineal gland begins to produce melatonin. The level of this hormone in the blood peaks in the middle of the night and gradually decreases in the morning, signaling the need to wake up.
Modulation of sleep phases by melatonin
Thanks to the natural secretion of melatonin, a person can fall asleep faster and maintain sound sleep throughout the night. This promotes the correct alternation of deep and REM sleep phases, which is extremely important for proper rest and recovery.
Biological clock and circadian rhythms
Circadian rhythms, sometimes called the biological clock, are a combination of biological processes that act like a timer, telling the body when to go to sleep and when to wake up. Melatonin in dietary supplement formbeing a synthetic analogue, can maintain normal circadian rhythms, especially if they are disrupted due to flights, time zone changes or non-standard daily routines.
Use of melatonin in sleep treatment
Melatonin in the treatment of sleep disorders
Age-related changes, stress, gadget screens, all this can throw off the balance of melatonin production. In such cases, taking melatonin as a medication or dietary supplement, such as those available from the iTAB store, may be recommended to help correct your sleep-wake cycle.
Recommended dosages and contraindications
Melatonin dosage may vary depending on a person’s specific needs and condition, but it is important to remember to consult with your doctor before taking it. Melatonin is contraindicated for pregnant, lactating women and children unless prescribed by a specialist, as it can affect hormonal levels.
Practical tips for using melatonin
How and when is the best time to take melatonin?
The ideal time to take melatonin is 30-60 minutes before bed. It is also important to consider that lighting and blue light from screens can impair its effectiveness, so it is recommended to minimize their use before going to bed.
Synchronizing Circadian Rhythms with Melatonin
In cases of circadian rhythm disturbances, such as jet lag or night shifts, melatonin can help reset the internal clock. The effectiveness increases if you additionally monitor your daily routine, regularly taking melatonin at the same time.
Interactions with medications and nutritional supplements
Before combining melatonin with other medications and supplements, you should consult your doctor as there may be interactions and altered effects. Certain substances can increase or decrease the effectiveness of melatonin, which can affect your overall sleep pattern.
Alternative Ways to Regulate Your Sleep Cycle
Natural Sources of Melatonin
In addition to dietary supplements, some foods, such as cherries, nuts, and whole grains, contain melatonin naturally. Including them in your diet can help improve your sleep quality.
Lifestyle and environment
A healthy lifestyle and optimization of sleeping space are important factors for normalizing sleep. Moderate exercise, reduced stress levels, and a dark, cool room to sleep in can have a positive effect on your sleep-wake cycle, as can a good sleep schedule.
Conclusion
Melatonin plays a key role in regulating the sleep-wake cycle, and understanding its functions can help improve sleep quality. Compliance with all the necessary conditions for its effective operation, as well as reasonable use in the form of supplements, can significantly improve a person’s somnological condition. Always consult a professional before starting any melatonin-based therapeutic measures.
