Blue Light Contributing to Bad Sleep?

Binge-watching your favourite show until the wee hours of the morning? Surfing the Net or texting late at night? If you find yourself unable to power down to get critical shut-eye, blue light could be to blame.

Exposure to TV, computers and smartphones, the three primary forms of blue light, can wreak havoc on your sleep as they impede the production of melatonin, a hormone that regulates sleep and wake cycles.

Want better rest? Stop watching TV and using gadgets two hours before your head hits the pillow. Other slumber-promoting tips include:

• Cut out caffeine after 2 p.m.
• Stick to a bedtime schedule
• Set your house to a cool temperature
• Read
• Consider using essential oils like lavender
