Sleep What Affects

* Circadian rhythm: Your circadian rhythm is your body's natural sleep-wake cycle. It's regulated by a part of your brain called the hypothalamus. The circadian rhythm helps you feel sleepy at night and awake during the day.

* Light exposure: Light exposure can affect your circadian rhythm. Exposure to bright light during the day can help you feel more alert and awake. Exposure to bright light at night can make it harder to fall asleep and stay asleep.

* Exercise: Exercise can help you fall asleep more easily and improve the quality of your sleep. However, exercising too close to bedtime can make it harder to fall asleep.

* Caffeine: Caffeine is a stimulant that can make it harder to fall asleep. It's best to avoid caffeine in the hours leading up to bedtime.

* Alcohol: Alcohol can make you feel sleepy, but it can also disrupt your sleep later in the night. It's best to avoid alcohol in the hours leading up to bedtime.

* Stress: Stress can make it harder to fall asleep and stay asleep. Relaxation techniques, such as yoga, meditation, and deep breathing, can help to reduce stress and improve sleep.

* Medical conditions: Some medical conditions, such as sleep apnea, restless legs syndrome, and thyroid problems, can disrupt sleep. If you have a medical condition that is affecting your sleep, talk to your doctor.

* Medications: Some medications, such as antidepressants, decongestants, and steroids, can cause insomnia as a side effect. If you are taking any medications that are affecting your sleep, talk to your doctor.
