Expatriates living in hot climates might want to heed the advice of Jan Turner and moderate the temperature of their sleeping quarters.
According to the spokeswoman from the Sleep Council, between 18 and 22 degrees C is the optimum temperature to get a good night's rest.
However, a comfortable, supportive and regularly replaced bed is also conducive to quality sleep.
People who are struggling to fit in sufficient sleep could consider taking out a medical plan after research has shown that sleep deprivation and disturbed sleep patterns can have serious health consequences.
Indeed, a survey conducted by Warwick Medical School, which looked at people from the US, the UK, Sweden and Japan, found that individuals who slept for less than six hours a night and had disturbed sleep had a 48 per cent greater chance of developing or dying from heart disease.
Their risk of developing or dying from a stroke was also increased by 15 per cent.
