In our busy, always-connected lives, sleep often gets pushed aside. Many people go to bed later and later, disrupting their
natural body clock—known as the circadian rhythm. This affects how well we function, no matter how many hours we sleep.
Dr. Saurabh Sethi, a gastroenterologist, sees more patients with symptoms linked to poor sleep habits. He stresses that when
you sleep matters as much as how long you sleep. Staying up past midnight can throw off hormones,
impair digestion, and harm brain health.
Sleep is essential for the body to repair itself, regulate hormones, and clear waste from the brain. Studies show that going to bed
at a consistent time—ideally before midnight—lowers the risk of heart problems and boosts immune and mental health.
Late bedtimes can lead to weight gain, as hunger hormones shift,
increasing cravings and reducing satisfaction.
They also negatively affect mood, increasing the risk of anxiety and depression.
