It keeps your body operating on a healthy wake-sleep cycle. Your circadian rhythm affects many other systems throughout your body. Most people\u2019s circadian rhythms are automatic, but certain factors like light can have an effect on them.<\/p>\n<h3 class=\"text-gray-900 font-bold leading-rem30px text-rem25px bp600:text-rem32px bp600:leading-rem38px mt-rem32px mb-rem16px break-words \" data-identity=\"headline\">What is circadian rhythm?<\/h3>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">Your circadian rhythm is the pattern your body follows based on a 24-hour day \u2014 it\u2019s the name given to your body\u2019s internal clock. This rhythm tells your body when to sleep and when to wake up. It also affects several other body processes, like your\u00a0hormones,\u00a0digestion and body temperature. It\u2019s like you have a tiny conductor inside your body, orchestrating a 24-hour symphony of biological processes.<\/p>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">Your body sets your circadian rhythm naturally, guided by your\u00a0brain. But outside factors, like light, can affect the rhythm, too. For example, when light enters your eye, cells send a message to your brain that it can stop producing\u00a0melatonin\u00a0(a hormone that helps you\u00a0sleep).<\/p>\n<h3 class=\"text-gray-900 font-bold leading-rem30px text-rem25px bp600:text-rem32px bp600:leading-rem38px mt-rem32px mb-rem16px break-words \" data-identity=\"headline\">How does circadian rhythm work?<\/h3>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">Your circadian rhythm makes sure your body\u2019s processes perform optimally at different points during a 24-hour period. \u201cCircadian\u201d in Latin means \u201caround or approximately\u201d (circa) \u201ca day\u201d (diem).<\/p>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">Your circadian rhythm coordinates the physical and mental systems throughout your body. For instance, your\u00a0endocrine system\u00a0controls hormones like\u00a0cortisol\u00a0for energy expenditure, and your\u00a0digestive system\u00a0creates proteins to match the timing of your meals.<\/p>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">Your circadian rhythm connects to an internal clock in your brain. This internal clock is located in a tiny cluster of cells known as the suprachiasmatic nucleus (SCN). The SCN is in a part of your brain called the\u00a0hypothalamus. Throughout the day, internal clock\u00a0genes\u00a0in the SCN send signals to control the activity throughout your body.<\/p>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">The SCN is sensitive to light. Light influences the signals that the SCN uses to coordinate circadian rhythms in your body. That\u2019s why circadian rhythms closely relate to day and night.<\/p>\n<h4 class=\"text-gray-900 font-bold leading-rem24px text-rem20px bp600:text-rem25px bp600:leading-rem30px mt-rem32px mb-rem16px break-words \" data-identity=\"headline\">Circadian rhythm in babies, toddlers and children<\/h4>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">Newborns typically don\u2019t develop a circadian rhythm until they\u2019re a few months old. That\u2019s why their\u00a0sleep patterns\u00a0tend to be erratic in those first few days, weeks and months. A baby\u2019s circadian rhythm begins to develop as they experience changes to their bodies and adapt to their new environment.<\/p>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">Babies usually start to produce and release melatonin when they\u2019re about 3 months old. Cortisol development occurs between 2 months and 9 months. Once toddlers and children develop a circadian rhythm, they should have a pretty regular sleep schedule, getting nine to 10 hours of sleep each night.<\/p>\n<h4 class=\"text-gray-900 font-bold leading-rem24px text-rem20px bp600:text-rem25px bp600:leading-rem30px mt-rem32px mb-rem16px break-words \" data-identity=\"headline\">Circadian rhythm in teenagers<\/h4>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">During their teen years, your child may experience a sleep phase delay, which is a shift in their circadian rhythm. When they were younger, they had early bedtimes (8:00 p.m. or 9:00 p.m.).<\/p>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">But your teen may not get tired until much later now. Their melatonin level may not rise until around 10:00 p.m. or 11:00 p.m. And as they\u2019re going to bed later, they need to sleep later into the morning. Teenagers still need nine to 10 hours of sleep a night.<\/p>\n<h4 class=\"text-gray-900 font-bold leading-rem24px text-rem20px bp600:text-rem25px bp600:leading-rem30px mt-rem32px mb-rem16px break-words \" data-identity=\"headline\">Circadian rhythm in adults<\/h4>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">If adults practice healthy habits, they should have a consistent circadian rhythm. If you follow a regular schedule and get seven to nine hours of sleep at night, your\u00a0bedtime\u00a0and wake time should remain stable.<\/p>\n<div class=\"mx-auto relative bp1100:hidden print:hidden bp900:overflow-hidden bp900:w-full\" data-identity=\"native-ad-mobile\"><\/div>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">People over the age of 60 may notice their circadian rhythm changing as they get older. You may go to bed earlier and wake up earlier, too. This is a typical part of aging.<\/p>\n<h3 class=\"text-gray-900 font-bold leading-rem30px text-rem25px bp600:text-rem32px bp600:leading-rem38px mt-rem32px mb-rem16px break-words \" data-identity=\"headline\">What can affect your circadian rhythm?<\/h3>\n<p class=\"text-gray-800 my-rem16px text-rem19px leading-rem34px \" data-identity=\"paragraph-element\">Light and dark\u00a0have the biggest effect on your circadian rhythm.
