On 30 March 2025, Europe will switch to Daylight Saving Time
(DST), moving clocks forward by one hour. While many people enjoy
longer evenings, scientists in sleep and circadian research argue
that DST can be harmful to our health. In this episode, we dive
into the controversy surrounding DST and answer three key
questions:

Why do chronobiologists want to get rid of DST?

What does the evidence say about DST’s impact on road traffic
accidents?

What does the public think about abolishing DST?

We hear from experts, including Prof. Till Roenneberg, Prof. Sara
Montagnese and Prof. Andrew Coogan, to break down the scientific
and political debates around DST. Plus, we explore the short- and
long-term health effects of DST on our health, the challenges of
assessing this impact, and why public opinion seems to contradict
expert recommendations when it comes to clock changes.
