A good night's sleep is just as important as regular exercise and a healthy diet . If you want to optimize your health or lose weight, getting a good night's sleep is one of the most important things you can do. Here are a number of evidence-based tips to sleep better at night: 1. Increase bright light exposure during the day: Daily sunlight or artificial bright light can improve sleep quality and duration, especially if you have severe sleep issues or insomnia. 2. Reduce blue light exposure in the evening: Blue light tricks your body into thinking it's daytime. 3. Don't consume caffeine late in the day: Caffeine can significantly worsen sleep quality, especially if you drink large amounts in the late afternoon or evening. 4. Reduce irregular or long daytime naps: Long daytime naps may impair sleep quality. If you have trouble sleeping at night, stop napping or shorten your naps. 5. Try to sleep and wake at consistent times: Try to get into a regular sleep/wake cycle - especially on the weekends. If possible, try to wake up naturally at a similar time every day.
