Trouble sleeping? Here's how to nod off quickly DW 08/15/2025
Briefly

Insomnia affects one in three adults, with heatwaves compounding their sleep difficulties. Even short heatwaves can decrease sleep duration by over an hour. Heat interferes with the body's cooling process necessary for sleep. To promote better sleep quality, keeping the bedroom cool and dark is essential. Regular exercise improves sleep by increasing melatonin and reducing stress, with those exercising 30 minutes daily sleeping about 15 minutes longer. Additionally, avoiding caffeine in the afternoon or evening helps prevent reductions in total sleep time.
One in three adults report some sort of insomnia, with around half indicating it disrupts their daytime functioning. Heatwaves can exacerbate sleep issues, leading to over an hour reduction in sleep duration.
Physical activity enhances sleep quality and duration. Adults who exercise at least 30 minutes daily enjoy longer sleep, with exercise increasing melatonin production and reducing stress.
Keeping a cool and dark bedroom is essential for improving sleep quality. Exercise, particularly moderate-intensity aerobic activity, is effective in treating insomnia.
Avoiding caffeine in the afternoon or evening is crucial because half of the caffeine remains in the body for 6-8 hours, potentially decreasing total sleep time.
