Sleep myths 'damaging your health'

Often if we're watching the television it's the nightly news… it's something that's going to cause you insomnia or stress right before bed when we're trying to power down and relax.

The other issue with TV - along with smartphones and tablets - is they produce blue light, which can delay the body's production of the sleep hormone melatonin. 

It takes the healthy sleeper about 15 minutes to fall asleep, but much longer than that… make sure to get out of bed, change the environment and do something that's mindless.

The research team says that when the alarm goes off, we should just get up.

Realize you will be a bit groggy - but resist the temptation to snooze. Your body will go back to sleep, but it will be very light, low-quality sleep.

Snoring can be harmless, but it can also be a sign of the disorder sleep apnoea.

This causes the walls of the throat to relax and narrow during sleep, and can briefly stop people breathing. People with the condition are more likely to develop high blood pressure, an irregular heartbeat and have a heart attack or a stroke. One of the warning signs is loud snoring.
