Winter really does us good in many aspects provided we keep ourselves warm in the season. First, the days get shorter and so our working hours are shortened accordingly. We can stay more time at home with our family members. Second, we enjoy a longer sleep every night, which ensures us an energetic day that follows. Third, the cold weather triggers our appetite for food. We need more food to supply the nutrients and calories needed by our bodies in the cold environment. Therefore, we usually gain weight in the season. It is said that cold weather enables people to live longer.
