Whether it was to cram for an exam or meet a tight deadline at work, everyone has pulled an all-nighter (or two) at some point in their life. At times like these, reaching for a strong kopi or a caffeine-filled energy drink to stay awake seems the natural thing to do.

Dr Toh weighs in on the effectiveness of caffeine-free, alternative methods that people can consider using to stay awake.
