In 2014 a Graduate Student Happiness and Wellbeing report identified that one of the key issues for PGR students was the need to promote healthy wellbeing and habits, in particular sleep .
The PGR students in the survey appeared to be aware of the importance of sleep and the benefits of sleep for wellbeing. They also had a desire to increase the amount of sleep they were getting regularly. Unfortunately, improving their sleep was something that they did not seem able to do. Lack of sleep can have a detrimental effect on a PGR student’s wellbeing and life satisfaction.
A study by Ness and Saksvik-Lehouillier (2018)  found that student satisfaction with life was increased when they had a good quality sleep, got the recommended amount of sleep overall and did not vary their sleep times. Lack of sleep can also affect your performance and impact on your problem solving, learning, academic performance, mood and mental health .
