What is Melatonin?
Melatonin is the hormone that regulates the sleep-wake cycle. But don’t be fooled! It only takes effect when the body has enough of it.
The good news is that your organism produces it naturally. The bad news is that caffeine, tobacco, alcohol, and night shifts can all mess with your body’s melatonin levels. To counteract its harmful effects, there is nothing like taking melatonin supplements to help you normalise your sleep patterns.
Responding to the formulation N-acetyl-5-methoxytryptamine is a pea-sized hormone secreted into the brain by the pineal gland, located in this important organ.
We have already mentioned that your body produces it naturally, but its intake via food or supplementation is in demand. In fact, its consumption continues the “in crescendo” trend of recent years.
Why? There is no other natural substance that offers similar benefits in terms of regulating biological rhythms. In short, melatonin plays a fundamental role in the natural sleep-wake cycle.
At night, their levels increase
As soon as the sun goes down, melatonin is activated. This is because its blood levels are highest at night. Research suggests that melatonin supplements, if taken at the right time (before bedtime), may be among the most useful in treating jet lag and other sleep disorders involving circadian rhythm imbalances.
Have you ever heard that melatonin is the “hormone of darkness”? Yes, you see, this popular hormone goes by many names, and this one, of course, is no coincidence.
Thanks to melatonin, the body maintains its biorhythm. But what is a biorhythm? It is nothing more and nothing less than the “biological clock” that makes sure you fall asleep and wake up, so it is an “internal clock” whose hands cannot stop working.
Benefits of the sleep hormone
The benefits of this incredible sleep supplement are undeniable and partly answer the question of what melatonin is for.
But if you think that the benefits of melatonin stop there, let us tell you that you are very mistaken, because this substance is a real “box of surprises” which, once opened, unfolds a host of therapeutic properties, each one more interesting and beneficial to your health.
Here are the main functions of melatonin in the body!
- It affects the circadian rhythm
- It promotes sleep
- It supports the immune system
- It aids eye function
- It reduces oxidative stress
- It has a positive influence on female reproductive hormones.
- It protects against radiation
- It controls numerous cellular processes, including the synthesis of key molecules
Apart from the fact that it is certainly good for sleeping there are other benefits of this formidable hormone that will not leave you indifferent, ranging from promoting the production of “growth hormone” to fighting cancer, including its powerful antioxidant action, protection of the mitochondria, promotion of the digestive system, treatment of mental disorders, insomnia, anxiety and depression, and its role in the fight against Parkinson’s and Alzheimer’s, among many others.
Find out more about these benefits in the detailed post we have prepared on the subject.
You can buy the best natural sleep products, such as melatonin.
Why does its deficiency occur?
The reasons that may lead your body to secrete insufficient melatonin, which interferes with night-time sleep or causes sleep problems, can vary widely.
- Ageing. As you get older, your body produces less melatonin, as the pineal gland tends to calcify. This means that the quality and duration of sleep decreases. As a result, around 40% of older people often complain of nocturnal disturbances ranging from insomnia itself to an inability to fall asleep, as well as reduced sleep quality.
- Exposure to electric light and blue light from screens of mobile devices, computers or TVs can reduce their release. Avoid light sources in the bedroom, including those from standby electrical appliance light points.
- Night shifts cause these workers to have problems sleeping during the day, as the pineal gland does not secrete enough melatonin in the morning.
- Cloistering oneself in dark spaces or sleeping too many hours can alter the circadian cycle and, consequently, the secretion of this substance.
- The consumption of alcohol, caffeine and nicotine also leads to a reduced release of melatonin.
- The intake of certain drugs, especially beta-blockers, cortisone and ASA also reduces their release.
- The suffering of certain pathologies such as autism or Addison’s disease leads to a reduction in the release of the above-mentioned.
- Intense sports at night and continuous stress are other factors that reduce its release.
- Serotonin deficiency can lead to decreased melatonin formation.
Are you thinking about taking melatonin? The first thing you should know is that it is a supplement that is completely safe for your health and that you can buy it in capsules, tablets, drops or sublingual tablets.
You should also pay attention to the instructions for the specific product. For your information, melatonin tablets are the most commonly used format, especially tablets that dissolve under the tongue and are quickly absorbed by the body.
Currently, the recommended daily dosage for sleep will depend on age and type of treatment, but typically ranges between 0.5 and 10 mg per day. Remember that, in sensitive people, lower doses are more effective.
Are you an athlete? If so, you may be interested to know that one of its main benefits for those who practise sport is its antioxidant properties. Training requires a higher metabolic utilisation of oxygen, which promotes pro-oxidant responses.
Melatonin also protects cells from oxidative stress caused by free radicals, thus fulfilling an anti-ageing function. Its regulation also helps to prevent feelings of fatigue, sleepiness, chronic tiredness and lack of energy.
While you sleep, your heart works less hard and benefits from “growth hormone” and “sleep hormone”.
Sport contributes to a better mood and to the production of melatonin. In conclusion, it is a tandem that works.
How to increase its level, more info here!
When you expose your body to artificial light at night you disrupt its natural production of melatonin, something you should avoid at all costs for your health, especially since this hormone plays a crucial role in preventing cancer and strengthening the immune system. A hormone that displays its many benefits at night and increasingly enjoys a well-deserved position as an aid to sleep and the prevention and treatment of disease.
Light pollution and temperature are among the factors that make it difficult to rest.
- Avoid watching TV or using mobile devices at least one hour before bedtime.
- Make sure you are regularly exposed to the sun.
- Sleep in complete darkness or at least as dark as possible.
- In case you need a night light, use a low wattage, orange or red bulb.
- Keep your bedroom temperature no higher than 21 degrees Celsius.
- Take a warm bath before going to bed.
- Avoid loud alarm clocks.
- Sunbathe in the morning as soon as possible.
- Pay attention to electromagnetic fields in your bedroom.
- Take melatonin food supplements in your preferred format.
Are there foods that produce this hormone?
The amino acid tryptophan is converted into serotonin, and once night falls, the pineal gland converts serotonin into melatonin. Foods rich in tryptophan help to increase serotonin levels.
You will find the highest levels of tryptophan in milk and dairy products, seafood, soya, meat, peanuts, and eggs. Ingesting carbohydrates in conjunction with tryptophan increases the melatonin-producing properties.
Tryptophan is not just any substance, but one that helps control anxiety, stress, and insomnia.
Thus, the ranking of the best foods to promote the production of melatonin is headed by:
- Nuts (especially walnuts and almonds)
- Fruits (especially bananas, cherries and tomatoes)
- Cereals (rice, oats and corn)
Jet Lag, another factor to consider
Are you familiar with jet lag? This phenomenon, which you have most likely experienced and often hear about in the news, refers to a temporary sleep disturbance suffered by people who travel by plane and cross different time zones.
The reason for this is none other than the slow adaptation of your body’s “internal clock” to the target time, which results in your rest and wakefulness being out of sync with the new environment.
If you suffer from jet lag, melatonin can help restore your sleep-wake cycle.
But jet lag is just one of the factors responsible for lower levels of this hormone! Some others have already been mentioned in this post, such as the dreaded schedule changes or tedious night shifts.
Melatonin at different stages
Do you think melatonin production declines with age? If so, you’re right. We are going to dedicate this section to tell you about the impact of this hormone on your body as you get older.
What about sleep in old age?
The effects of melatonin-based “sleeping pills” have been extensively studied in people over the age of 65. We have confirmed that melatonin can offer multiple benefits to elderly people suffering from sleep disorders.
This also explains why there are studies referring to melatonin as an anti-ageing supplement, as your doctor can tell you.
Melatonin lives up to the saying that “less is more”, as it has been found to be more effective in small amounts and to cause fewer problems.
Melatonin and Menopause: an unbeatable team
Women, needless to say, also suffer the ravages of insomnia during the menopause. Well, it has been shown that melatonin supplements can help to improve the sleep disturbances that occur during this period.
Such a study suggests that melatonin supplementation in perimenopausal and menopausal women restores hormone regulation, along with pituitary and thyroid function.
Therefore, the result of this study could not be more positive, concluding that melatonin can reduce bothersome symptoms of menopause along with the sleep problems experienced during this stage.
Here are their best combinations
When planning how to take melatonin, if nutritional supplements are your thing, you will already know that when you combine them, the results are even better! Because combinations of supplements are synergistic and boost benefits to the maximum.
What can you combine melatonin with? Well, this hormone combines perfectly with sleep supplements, promoting stress control, reducing anxiety and fostering a state of calm and well-being.
Are you looking for a restful sleep? Then, combine melatonin with…
