manhãs

Manhãs refers to the morning period of the day. It is generally considered to begin at sunrise and end at noon. This time of day is characterized by increasing light levels as the sun ascends in the sky. Many cultures and individuals associate the morning with a fresh start, new beginnings, and increased productivity. The biological and psychological effects of morning are well-documented, with many people experiencing higher alertness and cognitive function during these hours.

The transition from night to morning involves a complex interplay of biological rhythms, including the circadian rhythm, which regulates sleep-wake cycles. As darkness fades and light enters the environment, the body's internal clock signals a shift towards wakefulness. This physiological response is crucial for setting the tone for the day's activities. Socially, mornings are often a time for routine activities such as waking up, preparing for work or school, eating breakfast, and commuting.

Different societies may have varied customs and traditions associated with the morning. For some, it is a time for quiet reflection or prayer, while for others, it is a period of bustling activity. The concept of "morning person" describes individuals who naturally feel most energetic and alert in the early hours, contrasting with "night owls" who are more active later in the day. The duration and specific timing of what constitutes "morning" can vary slightly depending on geographical location and seasonal changes in daylight hours.
