Sleep apnoea is a sleep disorder involving repeated pauses in breathing during sleep, leading to hypoxia and frequent awakenings. The main risk factors include obesity, anatomical defects and unhealthy lifestyles and alcohol. Diet does not cure apnoea, but can influence its severity, sleep quality and the effectiveness of treatment, including by maintaining a healthy body weight and reducing inflammation. A diet that is easily digestible, rich in whole grains, vegetables and protein and sleep-promoting ingredients such as tryptophan is recommended, as well as avoiding stimulants and heavy meals in the evening.
