I like sunny days. Unlike cloudy days and rainy days, sunny days make me feel happy and energetic. When the sun is shining, I can easily find reasons to go outside and enjoy fresh air, green scenery, or some sports activities, such as jogging, cycling, or doing sports. Sunny days also bring warmth and light, which improves my mood and improves my work efficiency. I can read books, write letters or do some gardening in the sun. Moreover, sunny days often coincide with pleasant weather conditions, such as low humidity, mild temperature and clear sky, which reduce my stress and improve my health. Therefore, I always look forward to sunny days and cherish sunny days.
