The essentials

What is the ideal bedroom temperature for sleep in the UK?

16–18°C is optimal for most adults. A room that is too warm (above 21°C) disrupts deep sleep more than a room that is slightly cool.

Does screen time before bed really affect sleep?

Yes. Blue light from screens suppresses melatonin. Stop screens 30–60 minutes before bed, or use a blue light filter at minimum.

What scent helps you sleep?

Lavender is the most studied and effective. A pillow spray or diffuser with lavender essential oil helps most people fall asleep faster.
