Although the epidemic restricts going out, you can embrace the sun at home. In fine weather, you can open the windows to ventilate the room frequently, and bask in the sun on the balcony or the well-lit living room. Light helps regulate our day and night rules, and bright sunlight can help us adjust our biological clock to the best possible state. Even if the holidays are extended, people work less and spend more time at home, people should try their best to maintain a regular and regular diet and sleep. Three meals a day should be on time, not staying up late, but getting more sleep and reducing the state of reversed black and white. Regular diet and sleep can make our body work well, which in turn allows us to have a more stable mood.
