1. Work and rest: The winter solstice is the longest day in a year, and people have less energy in winter, so we must keep going to bed early and getting up late in winter solstice, because adequate sleep in winter can resist the cold.

2. Diet: tonic in winter, but not substantially. It's best to choose warm food to eat, such as mutton, the most common warm meat in winter, and you can use isothermal chicken soup to cook more soup.

3. Exercise: moderate exercise is still needed in winter, but it is not suitable for strenuous exercise in winter. You can choose some light sports, such as walking, yoga, jogging, climbing stairs and so on. And you should also pay attention to the cold when you are doing exercise.

4. Living environment: Try to open the window for ventilation from winter solstice to ensure that there is some fresh oxygen in the room to avoid catching a cold.

5. Mood: Stay healthy in winter, calm and worry less, keep cheerful and optimistic, and don't worry about trifles.
