Sleep patterns and evening habits shape morning wake‑up and skin appearance

Scientists explain that a person’s internal clock, or circadian rhythm, determines when they naturally feel sleepy and wake up. The chronotype—whether you are a morning or evening type—is influenced largely by genetics, with a shorter-than‑24‑hour internal cycle causing earlier sleepiness and earlier awakening. Hormones such as melatonin rise earlier in the evening for morning types, while cortisol drops later, signalling the body to rise. Light exposure, consistent bedtime, and regular exercise help stabilise the rhythm, whereas late caffeine, screen time and bright artificial light can shift it later.

Dermatologists identify seven common evening behaviours that can accelerate skin ageing and cause a tired look in the morning. These include a salty dinner that promotes fluid retention, alcohol before bed that dilates blood vessels, dry indoor air that dries the skin, insufficient sleep that hampers overnight skin repair, skipping nighttime skincare that leaves the skin un‑moisturised, untreated allergies that cause puffiness, and mouth breathing that dries oral and facial tissues. Experts advise moderating salt and alcohol intake, using a humidifier, maintaining a regular sleep schedule, applying hydrating night creams, treating allergies and, if needed, consulting a physician for breathing issues.
