Blue light or ambient sunlight during rest hours interferes with your circadian rhythm, disrupting sleep cycles, brain repair, and hormone production.
 

Studies show that poor sleep increases the risk of:

➤ Obesity

➤ Heart disease

➤ Depression

➤ Memory decline

"Sleep is the foundation of health. Light control is the first step." — Sleep Foundation Report

Of all the ways to naturally improve brain health – exercise and nutrition being the popular choices – sleep is the most overlooked lever for a high-functioning brain. 

This is due to a misunderstanding of what sleep really is and does for us.

Not merely the absence of being awake, sleep is a deeply active, highly restorative state that’s critical for memory, emotion regulation, learning, and long-term cognitive health.

Many scientists and doctors agree – there is no lifestyle change more important than getting enough sleep. Yet millions of us are in a state of low-grade sleep deprivation – often without realizing it.²  

Even missing a single hour can harm you.

Brain fog, irritability, and impulsive decisions are just a few of the short term effects. But over months and years there can be measurable declines in brain function – which could lead to much worse than forgetting where you put your keys.
