🚨 Key Physical Consequences:
Various Skin Problems: Without proper night-time regeneration and blood flow, the skin becomes sallow, dull, and loses its natural glow. It also triggers inflammatory skin conditions like eczema (16%) and psoriasis (7%).

Weight Gain & Cravings: Lack of sleep spikes your hunger hormone (ghrelin) and drops your fullness hormone (leptin), leading to overeating and sugary cravings. Women tend to gain weight in the hips/thighs, while men see it in abdominal fat.
Brittle Nails: Around 15% of sleep-deprived people reported weakened, brittle nails because the body’s natural cellular repair mechanisms are disrupted.
Cold Hands and Feet: Sleep loss impairs your circadian rhythm, making it harder for your body to manage and adjust its internal temperature, leading to cold extremities.
Constipation: Disrupting your sleep quality heavily impacts gastrointestinal health, significantly increasing the risk of digestive issues and constipation.
💡 In short: A healthy adult generally needs 7 to 9 hours of sleep per night to allow the body to repair itself properly.
