To ensure deep and comfortable sleep at night, it is crucial to avoid certain habits and adhere to a specific routine. Experts advise against drinking water right before bed, consuming caffeine, exercising immediately before sleeping, taking excessive daytime naps, and using electronic devices, as these activities can disrupt the natural sleep cycle. Conversely, for better sleep, one must eat dinner early, use a comfortable mattress, keep the feet warm, establish a specific 'bedtime routine,' and use a soft-lit alarm clock. Strictly following these rules helps condition the body and mind for quality rest, which in turn aids in improving overall health. By adopting these simple guidelines, you too can achieve sufficient sleep.
