While proper diet and regular exercise are great for the balance of essential hormones in your body, sleep plays an equally significant role. Its deprivation can lead to various hormonal disorders. A proper sleep cycle helps optimize the working of hormones like Cortisol, Testosterone, Human Growth Hormone (HGH) and Melatonin that are vital for the smooth running of physiological processes. Lack of sleep disrupts optimum levels of these hormones in your body causing problems like obesity, stress, anxiety, skin issues, diabetes and low vitality.
Human Growth Hormone
HGH produced by the pituitary gland is vital for the growth and development of key cells and tissues in your body. It helps build lean muscle mass and prevents excess fat from accumulating. The hormone made up of 191 amino acids assists in breaking down fat and influence the growth of lean body mass. Optimum levels of the hormone are linked to sleep and lack of sleep results in less production of the growth hormone. This causes excess fats to build up in your body leading to obesity and cardiovascular diseases. As the growth hormone is known to slow down aging in humans, sleep deprivation can cause the opposite effect creating problems like low muscle mass, low bone density, less exercise capacity and stress. Here you can find where to buy hgh.
It is recommended to have proper sleep in order to maximize the benefits HGH can provide to the body. Since HGH levels are best optimized during the third and fourth stages of regular sleep, it is important that you ensure the quality of sleep. A proper sleep cycle will promote hormonal balance and optimum HGH levels in your body that are required for smooth metabolic functioning.
Impact Of Sleep Loss On Hormones
Partial sleep loss affects the hormone concentrations in the blood, especially for the ones secreted by the pituitary gland like human growth hormone. The primary effect is low levels of HGH and an increase in the levels of stress hormone, cortisol, in the evening time. While in the day cortisol levels are low to provide you relaxation, lack of sleep induces a spike, which is dominant during the evening. This reflects stress and you eventually feel less energetic and low on vitality. Low cortisol levels in the body due to persistent sleep loss may also cause increased resistance to the hormone insulin, a factor that promotes disorders like obesity and diabetes. Sleep restriction may also cause psychological problems such as depression and anxiety because of high cortisol levels and low HGH levels.
Sleep deprivation also affects the levels of Thyroid Stimulating Hormone (TSH), free thyroxine index and leptin that are responsible for the smooth functioning of your metabolism. Additionally, the secretion of important hormones like HGH, Testosterone, Melatonin, and Insulin may also be impacted resulting in hormonal imbalance. This can lead to weight issues, fertility cycle issues, diabetes, and metabolic problems.
Impact of Sleep Restriction On Hormones Regulating Appetite
Sleep is directly linked to your diet, as hormones that control appetite are highly affected by lack of sleep. The duration of sleep affects the production of hormones like leptin and ghrelin. Sleep loss generally leads to an increase in appetite that is a result of decreasing levels of leptin released by fat cells in the blood. Leptin is responsible for the suppression of appetite by sending signals of satiety to your brain and its secretion is affected by how much you sleep. The leptin levels may decrease due to sleep loss and thus can lead to increased appetite leading to problems like high body fat and high blood sugar levels.
Sleep loss results in an increase in the levels of the peptide, ghrelin that is an appetite stimulant leading to an increased appetite that induces cravings for high carbohydrates. Since high levels of ghrelin that is secreted by the stomach in the blood stimulate frequent eating during the day, it may cause problems like obesity, cardiovascular diseases, high cholesterol levels, and diabetes.
Overall, lack of sleep leads to an increase in ghrelin and a decrease in leptin leading to enhanced appetite due to the inability of these two hormones to send satiety and correct caloric intake signals to the brain.
