- Get outside. Aim for at least 30 minutes of sun exposure each day.
- Turn out the lights. When it gets dark outside, dim the lights in your house and reduce blue or full-spectrum light in your environment.
- Avoid caffeine and stop smoking or chewing tobacco.
- Use the bedroom for sleep and sex only.
Also, consider these sleep aids: exercise (it will make it easier for your brain and body to power down at night), temperature (the ideal range is usually between 65 to 70 degrees Fahrenheit/18 to 21 degrees Celsius) and sound (a quiet space is key for good sleep).
