Sleep surroundings A lot of people struggle with sleep issues, often due to a stressful lifestyle or too many stimulants. But the health benefits of getting good-quality sleep are immense, so do put some effort into it. One of the ways is to sort out what I call 'sleep hygiene’. This means that, pre-bedtime, you should make sure your bedroom is really quiet, the temperature is comfortable and all light is minimised. Even little things like the light from a digital alarm clock have been shown to keep certain parts of the mind active, so use some eyeshades. You should be getting eight hours of sleep, and the earlier you go to sleep the better.
