The stages of sleep
A typical night of sleep cycles through light sleep, deep (slow-wave) sleep, and REM sleep multiple times, with deep sleep playing a particularly important role in physical recovery and REM sleep supporting memory and cognitive processing.
The hormonal connection
Melatonin signals the onset of the sleep phase, while cortisol, the body's primary stress hormone, needs to decline in the evening for a smooth transition into rest. See our Melatonin article for more detail.
The nervous system connection
Moving from a high-alert, sympathetic state to a calm, parasympathetic state is essential for falling and staying asleep — a process supported by neurotransmitters like GABA.
The consistency connection
Going to bed and waking up at consistent times helps reinforce a stable circadian rhythm, making it easier for the body to anticipate and prepare for sleep each night.
Where ingredients like Melatonin and Magnesium fit in
Nutrients and botanicals such as Melatonin and Magnesium have long been associated with complementing healthy sleep cycles — not replacing good sleep hygiene, but working alongside it.
When to see a doctor
Persistent sleep difficulties, including symptoms of insomnia or a diagnosed sleep disorder, should always be discussed with a physician. Supplements are not a substitute for medical care or prescribed treatment.
