New VUB research gauges impact of second lockdown on sleep

International research by the Vrije Universiteit Brussel and Brugmann Hospital’s Sleep Laboratory showed that the first lockdown had a negative impact on our sleep, including a tripling of the number of complaints of insomnia. To investigate whether this second lockdown also has an effect on our sleep and whether the lack of social and/or close physical contact with family, friends, etc can influence the onset or persistence of insomnia, the scientists are now starting a large-scale follow-up study. Participation is possible via

The questionnaire examines, among other things, the respondents’ sleeping habits, the need for physical contact, mental wellbeing and family situation. It takes about 10 minutes to complete. The survey is available in Dutch and French at

“The results of the first survey showed that the lockdown in spring 2020 did change our sleeping habits, with an increase in insomnia, especially among women, workers in contact professions and Covid patients. Surprisingly, a small percentage of people also slept better in these conditions and the intensity of the complaints appeared to decrease with age. With this follow-up survey we hope to gain more insight into whether these sleep complaints persist, occur less or more frequently and what the impact is of the lack of social contact on our sleep,” says Prof Olivier Mairesse.

About Press - Vrije Universiteit Brussel

Vrije Universiteit Brussel is an internationally oriented university in Brussels, the heart of Europe. By providing excellent research and education on a human scale, VUB wants to make an active and committed contribution to a better society.

The World Needs You

The Vrije Universiteit Brussel assumes its scientific and social responsibility with love and decisiveness. That’s why VUB launched the platform De Wereld Heeft Je Nodig – The World Needs You, which brings together ideas, actions and projects based on six Ps. The first P stands for People, because that’s what it’s all about: giving people equal opportunities, prosperity, welfare, respect. Peace is about fighting injustice, big and small, in the world. Prosperity combats poverty and inequality. Planet stands for actions on biodiversity, climate, air quality, animal rights... With Partnership, VUB is looking for joint actions to make the world a better place. The sixth and last P is for Poincaré, the French philosopher Henri Poincaré, from whom VUB derives its motto that thinking should submit to nothing except the facts themselves. VUB is an ‘urban engaged university’, strongly anchored in Brussels and Europe and working according to the principles of free research.
