3. Physical Activity
- Exercise Regularly: Engaging in physical activity during the day, whether it's aerobic or anaerobic, can significantly boost the quality of your sleep, particularly deep sleep. However, it's worth noting that intense workouts close to bedtime might disrupt sleep for some people 5.
4. Manage Light Exposure
- Light Control: Exposure to natural light during the day and minimizing artificial light, especially blue light, in the evening can help regulate your circadian rhythm, improving sleep onset and quality 6.
5. Avoid Alcohol and Caffeine
- Limit Alcohol Intake: Alcohol can fragment sleep and disproportionately impact the quality of deep sleep, especially in the first half of the night. It's best to avoid excessive alcohol close to bedtime 2.
- Caffeine Management: Avoid consuming caffeine later in the day to prevent it from interfering with your ability to fall asleep and stay asleep 6.
6. Consider Cognitive Behavioral Therapy (CBT)
- CBT for Insomnia: For persistent sleep issues, cognitive behavioral therapy for insomnia (CBT-I) is an effective treatment that can help modify behaviors and thoughts detrimental to sleep 1.
7. Sleep Medications (If Necessary)
- Medications: For some, certain medications like Doxepin or Trazodone can be beneficial for maintaining sleep, particularly in older adults. However, these should only be used under the guidance of a healthcare provider 1.
