Does gratitude help you sleep?
Of the ways gratitude might affect the body, sleep has the clearest support. People who practise it report falling asleep more easily and resting better.
When researchers have looked at gratitude and the body, sleep is where the clearest link shows up. A review of gratitude and physical health found its strongest bodily effect was on sleep, with people reporting they fell asleep more easily and rested better.
Why it might help
The route seems to run through the mind rather than the body. Going to bed with the day's worries still turning over keeps you alert just when you want to be winding down. Spending a few minutes instead on what went well gives the mind somewhere gentler to rest. Some people describe fewer of those racing, just-before-sleep thoughts on the nights they do it. The NHS lists gratitude among the simple things that can help with sleep and low mood, alongside rest and company.
If you would like a place to start, the three good things practice sits naturally at bedtime, and takes only a minute. Give it a week or two and notice how your evenings, and your nights, feel for you.
