Blue Block Glasses BioSync – Fitover
The human natural sleep-wake cycle is a finely tuned mechanism that has evolved over millions of years. This so called “body clock” is adjusting itself to align internal workings with the external environment such as light. Studies show that exposure to electronic light in the blue range late at night has severe impacts on our sleep. So what to do? Consider wearing blue light blocking glasses for better sleep hygiene.
