Detailed answer

Using electronic devices before bed can disrupt sleep cycles due to the blue light emitted by screens. Blue light suppresses the production of melatonin, a hormone that regulates sleep-wake cycles. This can make it harder to fall asleep and may lead to poorer quality sleep. Additionally, engaging with stimulating content on electronic devices can keep the mind alert and make it difficult to wind down and relax before sleep. It is recommended to avoid electronic device usage for at least an hour before bedtime to promote healthy sleep patterns.
