Aerobic exercise isn't just good for your heart, it also promotes better sleep quality.
How is your relationship with sleep? Around 30 to 40% of adults in the US say they experience symptoms of insomnia, meaning poor sleep is the reality for millions of people. When you live with sleep troubles, tucking yourself into bed isn't something you look forward to. Instead, your bed symbolizes frustration and discomfort after endless tossing and turning.
Take control of your sleep quality and give your body the rest it needs to properly function by dedicating a small part of your day to exercise. I'm not saying you need to take a hot Pilates class -- science says that even moderate exercise can help you achieve better sleep at night.
Here's what the studies say on regular exercise and sleep, and how to make bedtime something to look forward to again with a little physical activity.

Better sleep quality might just be a workout away. According to Charlene Gamaldo, medical director of the John Hopkins Center for Sleep, just 30 minutes of aerobic exercise can help you sleep better at night. Studies show that exercising can decrease sleep latency, the amount of time it takes to fall asleep, and increase the time spent in deep sleep.
Gamaldo also says it shouldn't take long to feel the effect. Many individuals reap the benefits of exercise for their sleep the same day as their workout. While experts are still exploring the possible links between sleep and regular physical activity, they have their theories.
Stress and anxiety are often major contributors to insomnia. During aerobic exercise your body releases endorphins, a hormone that promotes good feelings of wellbeing and happiness. Exercise also lowers cortisol levels, your body's stress hormone, allowing you to feel more at ease and fall asleep quicker.
Our body's core temperature typically stays around 98.6 degrees fahrenheit. It drops around 1 to 2 degrees as we sleep, specifically when we enter the non-REM sleep stage. On the flip side, it increases about 1 to 2 degrees during exercise.
After working out the body works to bring your temperature back down, a process that imitates the natural process that occurs during sleep. Your body recognizes this core temperature drop as a signal that it's bedtime and begins to wind down.
Every person has an internal clock called circadian rhythm that helps regulate our sleep/wake cycle. When that cycle is thrown off track, you can wind up getting tired much later than usual. Your internal clock can become misaligned by:
Exercise can help you realign your circadian rhythm and promote sleepiness so you feel more tired when bedtime rolls around.
