What's preventing good sleep? A few causes: -Irregular Sleep Schedules: Frequently changing bedtime and wake-up times can confuse the body's internal clock. -Light Exposure: Exposure to bright light, especially blue light from screens, can inhibit melatonin production, making it harder to fall asleep. -Melatonin Supplements: Taking melatonin can shift the timing of the body's internal clock, useful for managing jet lag and certain sleep disorders. -Sleep Trackers and Apps: Ironically, the use of technology to monitor sleep can sometimes lead to anxiety about sleep, making it more difficult to fall asleep. -Alcohol: While alcohol may initially induce sleepiness, it can lead to fragmented sleep and reduced sleep quality.
