Whether because of natural changes in our health or side effects of medication, many of us find it more difficult to get to sleep as we age. But there are some simple things you can do to drift off more easily – including enjoying a relaxing meal. To get to sleep, our bodies rely on a hormone called melatonin, which controls our sleeping and waking cycles. For example, during daylight hours, our body clock cuts down how much melatonin we produce to help us feel awake. Production of melatonin increases into the evening as we prepare to rest, and reaches its highest levels at night to keep us asleep until morning.
