Lights out
Tuesday, 2 March · 1 min read

Did you know that watching TV or checking your phone close to bedtime can affect your hormonal balance?

Melatonin – the sleep hormone – is produced by the pineal gland in our brain at nighttime, when it's dark.

Artificial light from TV, phones and computer screens (also called blue light) can suppress the release of melatonin by the brain. Along with regulating our sleep-wake cycle, melatonin plays a role in controlling body temperature, glucose levels and blood pressure – so stopping melatonin production through artificial light may have a more negative impact than just a bad night’s sleep.

What should you do? Dim your lights early and switch off your devices 2 to 3 hours before bedtime.
