2. Computer and mobile

Thinkstock

In a world dominated by electronics, avoiding computers or phones before bedtime is nearly impossible, but it may be necessary in order to get a good night’s sleep. Not only do computers and phones give off loads of unnecessary light (think of all the flashing lights on computers, phones and AC adapters), but they also serve as a constant reminder of work.

Mobiles go one step further with some studies suggesting that the radiation given off by our handsets may be disturbing sleep. Then there’s the added disruption of late-night texts, phone calls or e-mails that can wake you without you even knowing it (a phone’s vibration is more than enough to wake you mid-sleep).

Help yourself by disconnecting.
