Sleep
A delicate hormonal balance is crucial, as poor sleep can also disrupt the production and regulation of these hormones, creating a vicious cycle and problematic sleep patterns.
Melatonin
Recognized as the "sleep hormone," it informs the brain that bedtime is approaching by increasing levels in the evening as darkness sets in.
It is the key hormone for regulating your circadian rhythm, but it also has potent antioxidant properties, helping to protect cells, lipids, proteins and DNA.
Supplementing melatonin has become wildly popular, but regulations and dosages are inconsistent and should be considered before prolonged use.
Other hormones.
Cortisol: Known as the "stress hormone," elevated cortisol levels caused by stress or anxiety can disrupt both the ability to fall asleep and maintain sleep.
Estrogen and Progesterone: These sex hormones, especially in females, are crucial for regulating sleep. Their varying levels throughout the menstrual cycle can influence sleep patterns, with declines in progesterone just before menstruation often leading to difficulties in achieving restful sleep.
Testosterone: This hormone peaks during REM sleep, and low testosterone levels have been associated with issues like insomnia and snoring.
Growth Hormone (HGH): Also referred to as somatotropin, HGH plays a key role in energy regulation and storage.
Thyroid-Stimulating Hormone (TSH): Sleep deprivation can lower TSH levels, which negatively affects sleep quality.
