Caffeine
It is a terrible idea to sip a cup of green tea or coffee before bedtime. Caffeine is a natural stimulant that may affect your brain and make it more difficult to fall asleep. This effect may last up to 12 hours, but the exact number can vary. Therefore, it is better to consume caffeinated drinks earlier during the day, ideally in the morning. Keep in mind that many other products may also contain caffeine, such as chocolate, cacao, energy drinks, or soda. Make sure to check the ingredient list before purchasing to avoid them. [6]
