Sleep Better, Live Better

We all love to sleep

But why?
Why is sleep important?

Scientists have gone to great lengths to fully understand sleep's benefits. In studies of humans and other animals, they have discovered that sleep plays a critical role in immune function, metabolism, memory, learning, and other vital functions (1).

Consequences of bad sleep

The price of insufficient sleep may be poor health. Study after study has revealed that people who sleep poorly are at greater risk for a number of diseases and health problems. Lack of sleep exacts a toll on perception and judgment. In the workplace, its effects can be seen in reduced efficiency and productivity, errors, and accidents (2).

External factors

The bedroom environment can have a significant influence on sleep quality and quantity. Several variables combine to make up the sleep environment, including light, noise, and temperature. By being attuned to factors in your sleep environment that put you at ease, and eliminating those that may cause stress or distraction, you can set yourself up for the best possible sleep (3).
