Pandemic insomnia: What happens if you don’t get enough deep sleep?

Experts explain everything you need to know about the different stages of sleep to Katie Wright.

I discovered that most nights I was getting well below the roughly 90 minutes of deep sleep I needed.

Like many people I started to struggle with my sleep during the pandemic – finding myself staying up way past my usual bedtime or unable to drift off as quickly as usual.

Wondering whether tracking how much slumber I got each night could improve matters, I decided to try a fitness watch and found that, sure enough, being able to see how many Zs I’d caught (or not) the night before really was a good incentive to hit the hay earlier.
