Circadian rhythm internal clock and Cardiovascular Disease: Review of Disease Mechanisms. If circadian clocks within individual cells become sufficiently disturbed, Wright says, research clocm it Alpha-lipoic acid and skin rejuvenation, in some Circaxian, contribute to those cells becoming cancerous — if, say, cells begin to divide at inappropriate times. Blue light from screens messes with our circadian rhythm by suppressing our melatonin secretion. Then, as day breaks, the PER-TIM complexes break down, the block on PER transcription is lifted, and the cycle repeats.

Eating habits, such as having dinner or a large snack too close to bedtime, can send signals to the brain to rev up digestion and therefore stay awake, Wright says. When you exercise, it can send signals in the body that affect circadian rhythms, too, research suggests.

Long-term use of certain drugs, like caffeine , melatonin, or marijuana , may impact your circadian rhythms as well, Breus says. Maintaining a consistent sleep schedule — even on the weekends — is one of the biggest ways to keep your circadian clock on track, Wright says.

If you do shift work or work other irregular hours, you may not be able to avoid daytime sleep and nighttime work. Those people should pay particularly close attention to trying to prioritize other healthy choices, like getting enough physical activity and not smoking, because those healthy habits may decrease the health risks associated with overnight work, Wright says.

Adjust your sleep schedule by one hour per day starting enough days ahead that you will be on the schedule of your arrival destination by your departure date , in order to reduce jet lag upon arrival.

Research suggests that circadian rhythm disruption and misalignment may play a role in the development or progression of the following health issues: Diabetes Heart disease Some cancers Depression.

But other factors can disrupt circadian rhythms, too. This is especially important in the two hours before going to bed, Wright says. Reduce exposure to artificial light at night. In particular, try to minimize time spent in harsh, bright lighting like that from fluorescent bulbs or the blue light from your cellphone or computer.

Use lamps with soft lighting in your home, and if you need to use your devices, shift them to a setting where blue light is muted. Get outside in the morning. Or expose yourself to plenty of other bright light in the morning. Natural light via sunlight is ideal, but artificial light is better than none.

If you work indoors, Wright recommends trying to set up your desk near a window, if possible. If not, he suggests taking your morning coffee outdoors first to get some morning sun exposure. Ask your doctor about melatonin supplements. Melatonin is a naturally occurring hormone produced by the body to help promote sleep at night.

In some cases, such as before or after traveling across time zones or for short-term bouts of insomnia, low doses of melatonin supplements 1 to 3 milligrams can help the body readjust to a healthy sleep-wake schedule, according to Johns Hopkins Medicine.

In recent years, researchers have discovered even more ways your circadian clock can affect your health. For example, there is now research suggesting that eating at set times of day, or time-restricted feeding , can prevent obesity and metabolic diseases.

Depression and other mood disorders may also be linked to dysfunctional circadian control that lead to changes in how your genes are expressed.

The time of day when you take your medicine can also affect how well it works and how severe any side effects might be. Likewise, your biological clock is a potential target for cancer chemotherapies and anti-obesity treatments. Circadian clocks also provide a potential answer to when is the best time of day to maximize the benefits of physical exercise.

To study this, my colleagues and I collected blood and tissue samples from the brains, hearts, muscles, livers and fat of mice that exercised either before breakfast in the early morning or after dinner in the late evening.

We used a tool called a mass spectrometer to detect approximately to molecules each organ produced. These metabolites served as real-time snapshots of how the mice responded to exercise at specific times of day.

Using this atlas, we saw that time of day affects how each organ uses energy during exercise. For instance, we found that early morning exercise reduced blood glucose levels more than late evening exercise. Exercise in the late evening, however, allowed the mice to benefit from energy they stored from their meals and increased their endurance.

Of course, mice and humans have many differences along with their similarities. For one, mice are more active at night than during the day. Still, we believe that our findings could help researchers better understand how exercise affects your health and, if timed appropriately, can be optimized based on time of day to meet your personal health goals.

I believe that the field of chronobiology is growing, and we will produce even more research providing practical applications and insights into health and well-being in the future.

In my own work , for example, a better understanding of how exercising at different times of day affects your body could help tailor exercise plans to maximize specific benefits for patients with obesity, Type 2 diabetes and other diseases.

There is still much to learn about how your circadian clock works. But in the meantime, there are some tried and true ways people can synchronize their internal clocks for better health. These include regular exposure to sunlight to trigger the endocrine system to produce vitamin D, staying active during the day so you fall asleep more easily at night and avoiding caffeine and reducing your exposure to artificial light before bedtime.

They're the natural physical, mental, and behavioral changes that happen in the body, and they follow a hour cycle, usually in response to lightness and darkness, according to the National Institute of General Medical Sciences. One example is being awake during the daytime and sleeping at night. The presence of one set of molecules triggers the production of other molecules, which in turn triggers the next phase in the cycle and enables cells to keep time, explains Kenneth Wright Jr.
