Understanding stress: How it affects sleep performance and cognitive functioning

This week we’re sharing some groundbreaking WHOOP research about the importance of stress, rest, and recovery — and how they are key ingredients to improving performance and giving you a competitive advantage. One of the best ways you can improve your performance is being more aware of the mental and physical factors at play. This research showed that, for every 45 minutes of sleep debt a person accrued, they had a 5 to 10 percent decrease in mental control the following day — and for every 30 minutes of slow wave sleep gained, that person saw a 5 to 10 percent increase in mental control the next day. Vice President of Performance Kristen Holmes sits down with the researchers, Dr. Jemma King and Nadia Fox, to discuss the goal of the study (3:33), why WHOOP was chosen to measure stress (5:15), the study findings (14:18), major takeaways (16:46), sleep and performance (22:49), light exposure at night (26:55), stress and sleep (30:56), phone light before bed (37:06), proper breathing (38:40), and nutrition's impact on performance (43:56).
