Chapters

A 2021 National Survey of sexual well being showed that ED prevalence is highest among older age groups, but it's also increasing with shocking frequency in younger individuals. People in their 20s and 30s and 40s are more and more coming in and seeing urologists for erectile dysfunction issues. Another study on physically active men during Ramadan in 2020 showed that napping reduced their rating of perceived exertion while they were sprinting how hard they felt like they were working. Another study in 2022 also showed lower subjective muscle soreness and an increased ability to work out at a higher intensity in those who threw in again a 40 minute nap in the afternoon about three hours prior to working out.
