How to stay warm during winter

There are many ways to stay warm during winter, but today I will introduce to you the methods that I find the most useful among all. When the temperature starts to drop at night, I make some tea and add some ginger slices in, so that when I drink it, my body will be warmed up immediately. I always wear many layers of clothes, so when I get on a train or enter a warm space, I will not find the atmosphere too hot or stuffy. The final method that I use is exercise. Before I sleep, I usually do some exercise to warm up my body and at the same time, have a better sleep. I hope these tips for staying warm can help you!
