Can SMILE, our multi-component intervention, which combines cognitive-behavioural therapy for insomnia, mindfulness, stress, and lifestyle components, improve sleep quality? Can it also improve mood and quality of life and prevent depression and anxiety in the long term?

Sleep disorders have a significant influence on our physical and emotional health. Sleep should therefore receive more attention within lifestyle medicine, says Professor Gert Jan Lammers. He will give his inaugural lecture on Friday 20 May entitled: ‘Getting to sleep’.

Young children, adolescents and students may experience learning difficulties as a result of lack of sleep. Dr Kristiaan van der Heijden investigates sleep problems and solutions for various age groups.

Students who have a chronic lack of sleep have lower grades and find it harder to concentrate. Around a third of students do not feel well rested enough to be able to study properly.

A restless night aggravates symptoms in those experiencing suicidal thoughts, as psychologists Liia Kivelä and Niki Antypa have found in their study on the short-term risk factors of suicide. They argue that targeting sleep could thus be essential for suicide prevention.

Learning about circadian rhythms can help students to improve their sleep and overall well-being

Do you often find yourself exhausted in the lecture hall or at your workplace? Not great for your mental well-being, as Laura Pape knows. She is investigating how an online self-help program can assist in addressing sleep issues and preventing mental health problems. Join her on this elevator pitch…

During adolescence, mood disorder onset peaks. Mood variability is associated with negative mental health outcomes, so understanding biological factors that might be associated with mood variability, such as sleep and structural brain development, could elucidate the mechanisms underlying mood and anxiety…

Lecture, Economic and Social History Brown Bag Seminar

Andrea Evers has received an NWO research talent grant with Jelle van Leusden as the PhD candidate. This grant enables them to start a research project to examine whether automatically regulated responses, such as the circadian rhythm, can be conditioned during sleep.

Issues such as climate change, the depletion of natural resources or social inequality are too complex to be addressed from a single scientific discipline or by a single country. Leiden University has the expertise to bring the resolution of these enormous problems a small step closer.

Latent variable modeling of students' solution strategies and performance

How do you keep students’ attention when you have to compete with digital distractions like Facebook? What skills do you need in today’s rapidly changing world? Teachers attended a congress on innovative teaching on 23 November.

This study tests whether behavioural problems at a young age are related to early reading and mathematics development.

The Netherlands Association for Sleep-Wake Research is studying this issue. Lead researcher Kristiaan van der Heijden, Leiden psychologist and sleep specialist, invites students to take part in the study.

The complexity of an intelligence problem determines to a great extent the certainty that can be provided by intelligence and security services.

The Learning and Behavior Problems in Education program group is responsible for teaching in the area of learning problems.

The research of the group Learning and Behavior Problems in Education addresses learning difficulties in the areas of reading (technical reading and reading comprehension) math and writing, and examines learning-related behaviors behaviors.

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…

Our mission is to bring together research and practice focused on the improvement of mental health and the enhancement of treatment / psychotherapy success. To reach this goal we focus on the following paths:

What are best practices for teaching students to engage with 'wicked' problems?

To facilitate the search for new antibiotics. That is the aim of Gilles van Wezel, professor molecular biotechnology at the Institute of Biology Leiden (IBL). He wants to do this by looking at similarities in the DNA of antibiotic-producing bacteria. Van Wezel has been awarded an ERC Advanced grant…

Leiden University social scientists have shown that customised intervention pays off. A new fundamental research-based approach in children who are in danger of going off the rails has delivered spectacular results.

Proactive zebrafish appear to have a much stronger wake-sleep rhythm than reactive fish. In the most reactive fish, rhythmicity appears to be lacking completely. This is shown with research by Leiden biologists, published in December 2018 in the journal BMC Biology.

Microorganisms that temporarily ‘go to sleep’ play an important role in the evolution and survival of a population. Mathematician Shubhamoy Nandan conducted research on the effect of this characteristic called ‘dormancy’ in a novel mathematical model.
