Daylight Saving Time under scrutiny by NTR Wetenschap and NPO 3 op Reis
On June 21 – the longest day of the year – NTR Wetenschap released a short video about the effects of light on our biological clock. Chronobiologist Inês Machado Chaves, affiliated with BioClock, explains how light impacts our bodies and why we would be better off abolishing daylight saving time.
NPO 3 op Reis also addressed the topic in an online article titled: “Should we abolish daylight saving time? We’re living in Kyiv’s time zone.” The article explains that the Netherlands is geographically not aligned with its current time zone, which can negatively affect our sleep and health. BioClock is explicitly mentioned as a consortium advocating for the adoption of permanent standard time. You can read the full (Dutch) article here.
