Difficulty in sleeping can happen due to stress, an irregular routine, excessive screen use, caffeine intake, or certain medical conditions. Before using any sleep medicine, it is important to improve sleep habits, as these often make the biggest difference. Try to go to bed and wake up at the same time each day, avoid caffeine in the evening, and limit screen use before bedtime. Make your bedroom dark, quiet, and comfortable, and avoid heavy meals late at night. Regular exercise during the day may also help. If these measures do not help, medicines may be considered, but only after medical advice. A doctor may suggest short-term use of melatonin or certain antihistamine-based sleep aids, but they may cause next-day drowsiness and are not suitable for everyone. Strong sleeping tablets like zolpidem or benzodiazepines should only be taken under strict supervision, as they can cause dependence. Avoid self-medication, especially if you have other health conditions or take regular medicines. It is important to consult a doctor to find the exact cause and choose safe treatment.
