How insomnia becomes self-reinforcing
Once you've had a string of bad nights, your brain starts associating the bed itself with frustration. The anticipatory anxiety alone, 'what if I can't sleep again?', is enough to keep you awake. This is conditioned arousal, and it's the engine behind most chronic insomnia.
What it costs
Insomnia is linked to higher rates of depression, anxiety, cardiovascular disease and dementia. In the short term it tanks immunity, raises insulin resistance, shrinks your patience and quietly changes your personality. People around you notice before you do.
Why melatonin alone rarely fixes it
Most over-the-counter melatonin is 5-10x the physiological dose. It can help you fall asleep but leaves you groggy and shifts your circadian rhythm in the wrong direction. It also does nothing for the underlying nervous-system arousal.
How Sleeptruly helps
L-Tryptophan supports your body's own melatonin curve at the right time and dose. L-Theanine and Passion Flower quiet the conditioned arousal. Glycine and Apigenin deepen the sleep you do get, so a 6-hour night actually restores you.
