why i mostly active at nighttime and not active in daytime?

Feeling more active at night rather than during the day can be attributed to several factors, including:

**Chronotype**: Individuals have different natural sleep-wake cycles, known as chronotypes. Some people are "night owls," meaning they feel more energetic and alert during the evening and nighttime.

**Circadian Rhythm**: Your internal biological clock, which regulates sleep-wake cycles, might be set to a pattern that makes you feel more awake at night.

**Lifestyle and Habits**: Work schedules, social activities, and personal habits can influence when you feel most productive. If you frequently stay up late or have activities at night, your body may adapt to this routine.

**Environmental Factors**: Nighttime can be quieter and less distracting, providing a more conducive environment for focus and activity.

**Psychological Factors**: Some people thrive in the nighttime environment due to decreased noise or interruptions, making it easier to concentrate.

**Sleep Quality**: If you are not getting adequate rest during the night, you may feel tired during the day and thus become more active later when you feel you can get things done.

If you're concerned about your sleep patterns or they affect your daily life, consider consulting a healthcare professional or a sleep specialist for further evaluation and guidance.
