The actor shared that she actually feels sleepy when daylight begins and enjoys the sound of early morning birds, a schedule that is the complete opposite of a typical daily rhythm.

While such a routine may work temporarily due to lifestyle or professional demands, experts warn that it can significantly disrupt the body's natural timing system, known as the circadian rhythm. This internal clock is designed to align with daylight and darkness, helping regulate sleep, hormones, metabolism, and overall health.

Sleeping during the day and staying awake at night can confuse this rhythm. Exposure to sunlight in the morning usually signals the brain to stay alert, while darkness triggers the release of melatonin, the hormone responsible for sleep. In reversed schedules like this, the body struggles to maintain hormonal balance, which can lead to poor sleep quality and constant fatigue even after several hours of rest.

Over time, such patterns may also affect mental and physical health. Studies link disrupted sleep cycles to issues like reduced concentration, mood swings, weakened immunity, and even increased risk of conditions such as obesity and diabetes. Night-oriented schedules can also limit exposure to natural sunlight, which is essential for vitamin D production and maintaining overall well-being.

Another concern is social and lifestyle misalignment. Most daily activities-work, meals, and social interaction-are structured around daytime hours. Following a nocturnal routine can lead to irregular eating patterns, reduced physical activity, and a sense of isolation, all of which can further impact health.

However, experts note that if someone must follow such a schedule, consistency is key. Maintaining fixed sleep and wake times, limiting screen exposure before sleep, and ensuring a dark, quiet sleeping environment can help reduce negative effects. Strategic light exposure-like avoiding bright light before sleep and getting sunlight after waking-can also support better adjustment.

D'Souza's routine highlights a growing trend among people with flexible or creative work schedules. While it may feel comfortable in the short term, aligning sleep with the body's natural rhythm remains one of the most important factors for long-term health and performance.
