The more sleep we have, less time we stay awake to create our sleep quality for following night. Our body does not get exposed to sufficient sunlight to lower our melatonin levels, so we stay sleepy throughout day.

The deeper stages of sleep (stages 3 and 4) are most restorative. This is where body regenerates. Most of stage 3 and 4 sleep takes place in first 4 hours of our sleep. The rest of night is spent in REM (dreaming) sleep and lighter stages. Stages 3 and 4 are also where immune system repairs and strengthens itself. It is vital to get this type of quality sleep.

A good start is to make sure we get enough exercise during day, this gives us a three-fold benefit. It gets us out into sunlight which reduces our melatonin levels, it raises our body temperature so we feel energized and it tires us in a healthy way so we can have more deep sleep at night.

So when you come home from work feeling worn out and weary, don't veg out in front of TV. Put on those sneakers and go for a brisk walk around block instead!

Because detoxing can be a shock to body, it is recommended by nutritionists that you start it programme at a time when you don’t have a lot of other things on – especially not anything strenuous or physical.

Many people report a variety of symptoms when they first start a detoxing dietary programme, for example, lack of energy, an outbreak of spots, headaches etc. But this is just part of body’s cleansing process and, so detox fans report, at end of dietary programme, you should feel lighter, your skin should be clear and you’ll have renewed energy levels.
