   • While short naps can be beneficial, especially for older adults, avoid napping for extended periods during the day, as it can disrupt your nighttime sleep schedule. If you need to nap, keep it brief (20-30 minutes) and avoid napping late in the day.
7. Stay Active and Exercise Regularly:
   • Engage in regular physical activity during the day, as it can promote better sleep quality and help regulate your sleep-wake cycle. Aim for at least 30 minutes of moderate-intensity exercise most days of the week, but avoid vigorous exercise close to bedtime.
8. Limit Screen Time Before Bed:
   • Reduce exposure to electronic devices such as smartphones, tablets, computers, and TVs before bedtime, as the blue light emitted from screens can suppress melatonin production and interfere with your ability to fall asleep. Establish a screen-free wind-down period before bedtime.
9. Eat a Balanced Diet:
   • Maintain a healthy and balanced diet, and avoid heavy or spicy meals, large meals, and excessive fluid intake close to bedtime, as they can cause discomfort and disrupt your sleep. Opt for light, easily digestible snacks if you’re hungry before bed.
10. Seek Professional Help if Needed:
    • If you’re experiencing persistent sleep disturbances or difficulty managing insomnia on your own, don’t hesitate to seek help from healthcare professionals, including primary care physicians, sleep specialists, or mental health professionals. They can provide personalized guidance, evaluation, and treatment options tailored to your needs.

By adopting these preventive measures and prioritizing good sleep hygiene, you can reduce the risk of developing insomnia and promote better sleep quality and overall well-being. Consistency and persistence in implementing these strategies are key to establishing healthy sleep habits and preventing sleep disturbances over the long term.
