Joel Gascoigne, cofounder and CEO of Buffer, takes a 20-minute walk every evening before bed.
"This is a wind down period, and allows me to evaluate the day's work, think about the greater challenges, gradually stop thinking about work, and reach a state of tiredness," he writes in a blog post.
While it's a popular belief that exercise before bed can prevent sleep, the National Sleep Foundation actually found in 2013 that exercising whenever you can, even at night, helps you sleep better. Numerous studies have also found that walking reduces stress and anxiety.
