Which of the following is advised against at night for better sleep hygiene?

Checking the clock while trying to fall asleep disrupts the natural process of falling into a restful state. This behavior can create anxiety about the time and how long it is taking to fall asleep, which can ultimately lead to increased alertness and stress. The act of frequently glancing at the clock can reinforce negative associations with bedtime, making it harder to relax and drift off.

In terms of sleep hygiene, it is important to create an environment conducive to rest. Other practices, such as maintaining a consistent sleep schedule, avoiding screens before bed, and drinking herbal tea, are supportive of healthy sleep habits. Maintaining a regular schedule helps regulate the body's internal clock, minimizing the likelihood of insomnia. Avoiding screens can reduce exposure to blue light, which interferes with the production of melatonin, the hormone that facilitates sleep. Drinking herbal tea, with its calming properties, can also promote relaxation before sleeping. Therefore, avoiding the practice of checking the clock is essential for improving sleep hygiene and enhancing overall sleep quality.
