Health impacts of insomnia and the role of melatonin

Insomnia and insufficient sleep can lead to severe health consequences, including impaired concentration, weakened immune systems, and metabolic disruptions. According to somnologist Beatrice Mahler, lack of sleep affects glycemic metabolism, increases the predisposition to fat tissue accumulation, and raises the risk of cardiovascular diseases and heart disorders.

Sleep deprivation also impacts memory, attention, and workplace performance. In Romania, one in two people reports feeling physically exhausted due to chronic stress, which can lead to burnout.

Melatonin, a hormone secreted by the pineal gland, plays a crucial role in regulating the circadian rhythm and the sleep-wake cycle. While commonly used as a supplement to combat insomnia, melatonin also contributes to immune support and may help manage anxiety and stress. Adequate melatonin levels are linked to brain health, potentially protecting against cellular degradation associated with conditions such as Alzheimer’s and Parkinson’s diseases. Melatonin production may decrease after age 60 or due to certain illnesses and medications.
