Sleep Your Way to Smart
What’s the best way to boost your brain power? More and more evidence is pointing to quality sleep as the number one way to improve cognitive health.
Sleep helps facilitate five essential functions directly related to brain fitness including memory consolidation, organ repair, brain development, muscle growth and repair, and neurogenesis, which is the growth of new brain cells known as neurons (1-5). By getting enough quality sleep, your brain is able to perform optimally—increasing concentration, memory, and decision-making.
The sleep-wake cycle is controlled by “circadian” rhythms, which are characterized by a rhythmic release of hormones that induce a state of alertness or drowsiness depending on the molecular clock that is present in every cell of the human body. Although the human clock is endogenous (“built-in”), it can be disrupted by the external environment, including exposure to artificial light and irregular meal, work, and sleep times.
Melatonin is the commander-in-chief when it comes to circadian rhythms. This hormone is produced by the pineal gland in the brain. It is inhibited by light, which is detected by the retina and signaled to the brain, and stimulated by darkness—this is why drowsiness sets in during nighttime.
Recent research also shows the influential role melatonin has in brain development. Neurogenesis occurs during sleep and dramatically decreases with sleep deprivation. Studies indicate that supplementation with melatonin can re-establish circadian rhythm and increase neurogenesis in the hippocampus—the area of the brain that forms memories (6, 7).
Unfortunately, our ability to make melatonin declines with age. Melatonin levels begin to drop below optimal levels by about age 35 (8, 9). Without sufficient melatonin, you are more prone to sleep disturbances that can lead to poor quality sleep and ultimately accelerated aging of your organs, including the brain.
One in three Americans suffer from sleep-related problems. Lucky for us, Isagenix has a safe and effective solution—Sleep Support & Renewal contains immediate and time-released melatonin in a convenient spray combined with a concoction of relaxing ingredients including:
- L-theanine—known for its calming and relaxing properties
- Valerian—an herb used to help decrease nervous tension, excitability, and stress
- Chamomile—traditionally used for calming
Based on numerous studies and clinical use, melatonin is extremely safe when taken in the correct form, dose, and at the right time. Evidence supports melatonin’s ability to help people sleep longer and enables those who wake too early to fall back asleep (9). Contrary to what many believe, if melatonin is taken correctly it does not act as a pharmaceutical sedative and will not induce a “hangover” effect in the morning. Rather, it helps reset the body’s sleep-wake cycle and improves the overall quality of sleep.
In a study of 170 patients aged 55 and over with a history of sleep problems, melatonin supplementation significantly improved quality of sleep as well as alertness in the morning (9). More importantly, the patients didn’t suffer from rebound effects after discontinuing the use of melatonin. In fact, it was evident that patients still benefited after they stopped taking the melatonin, suggesting a sustained effect rather than just symptom management.
The first step to boosting brain power is getting enough quality sleep. Isagenix Sleep Support & Renewal is a safe and effective way to get the sleep your body and brain crave. The smart thing to do would be to keep it next to your bedside within easy reach for use every night.
