Research has shown that there is a strong correlation between the amount of sleep a person gets at night and the ability to lose or maintain weight. This may be caused by external factors such as stress and family commitments. It may also be caused by internal factors such as decreasing melatonin levels.
Introduction Of Melatonin
Melatonin(C13H16N2O2), also known chemically as N-acetyl-5-methoxytryptamine, is a natural hormone that is made by the pineal gland. The pineal gland is approximately the size of a pea and is located in the center of the brain. It helps regulate sleep cycles on a 24-hour basis, telling us when we are tired and need to go to sleep. Its levels rise in the evening to make us feel sleepy. They remain high throughout the night to help us remain asleep. As morning approaches, the levels decrease, which allows us to wake up.
Relationship Between Sleep
Melatonin is stimulated by darkness but is suppressed by light. This is why we tend to want to sleep at night and be awake during the day. This natural hormone controls the circadian rhythm in the body, making us feel tired and letting us know when it is time for sleep.
When levels begin to drop, symptoms of sleeplessness or even insomnia can occur. Those suffering from a deficiency in melatonin may notice that it is harder to fall asleep or to stay asleep during the night. As we age, the levels will naturally decrease, making sleep irregularities more common. It is possible for some older people to produce little or no hormone at all.
Relationship Between Weight
Studies at the Washington School of Medicine in St. Louis show a correlation between low melatonin levels and weight gain, especially around the stomach area. When its levels are low, the ability to get a good night’s sleep diminishes. A lack of sleep not only causes us to feel tired and frustrated, it also increases the secretion of certain hormones such as leptin, cortisol and ghrelin. Increased levels of these specific hormones cause the body to gain weight and make the ability to lose weight much more difficult.
Supplements For Melatonin
It is possible to increase low melatonin levels and restore them to normal levels. The levels are affected by light. Being out in the sunlight can naturally increase them. Some foods, such as oatmeal, cottage cheese, tuna and soy nuts, are also known to increase. The natural hormone can also be found in the form of a dietary supplement. The dosage needed varies by person, and the use of these supplements should be discussed with a physician before using.
