You may have an overnight sleep study, which provides information about how much your oxygen levels vary while you are asleep. Changes in oxygen levels overnight can be due to a condition called obstructive sleep apnoea or may occur as a result of lung disease. This test involves wearing heart rate and oxygen level monitors while you are asleep.
Asthma is a common lung condition that causes occasional breathing difficulties. There is no cure for asthma but in most sufferers, available treatments keep their symptoms under control.

Dr Alanna Hare, consultant in respiratory and sleep medicine, was interviewed by Delicious magazine about how certain food groups may help people to sleep. Dr Hare explained: “There is some literature that suggests consuming foodstuffs high in tryptophan or melatonin may increase sleep duration and quality.” However, she stressed that there’s limited clinical evidence, adding: “Overall, the extent to which diet and nutrients can boost sleep remains unclear.”
