Body Clocks: Keep Them Ticking On Time And Stay Healthy

Body clocks are the internal mechanisms that keep your body healthy and operating at maximum efficiency. These biological clocks help you feel alert during the day, hungry at mealtimes, and sleepy at night. Keeping your body’s daily cycles, or circadian rhythms, in sync is important for your health.

Circadian rhythms are big influencers in the body. They affect almost every part of your physiology in one way or another. To maintain your health, it is important to understand how your body clock works.

Body Clocks: How it Works

Our natural daily rhythms are synchronized with the sun. A “master clock” in the brain receives direct input from the eyes and coordinates all the biological clocks in the body. During the day, it sends signals to other brain regions to make hormones that will help keep you awake, boost your heart rate, and give you energy. In the evening, when less light enters your eyes, it triggers production of a hormone called melatonin. Melatonin makes you feel drowsy and helps you stay asleep.

 

Body Clocks: Genetics-What It Does

Your biological clock’s “settings” are determined by specific genes.  These settings can affect body temperature, blood pressure, activity level, inflammation (your body’s protective response to injury or infection), fertility, mood, and brain functions. Even the timing of health-related events can be related to your biological clocks. For instance, heart attacks are more likely to occur early in the morning, when the level of a hormone called cortisol starts its daily rise.

Many of your body’s normal daily activities, like sleeping, waking, and eating, are patterned around this 24-hour cycle.

Body Clocks: Timing Your Activities Is Everything

Researchers have found that eating later in the day, closer to when melatonin is released, can disrupt the body’s natural rhythms. This can lead to increased body fat and weight gain, which are often associated with obesity, heart disease, and diabetes.

Time of day has also been shown to impact the effectiveness and side effects of certain medications, including those used to treat cancer.

For instance, shift workers who must be on the job after the sun goes down are fighting their biological clocks. They may be tired at work and have trouble falling or staying asleep during daylight hours after work. Studies show that shift workers have increased risk for heart disease, digestive disturbances, cancer, depression, and other health problems.

Moreover, traveling across time zones can also disrupt your circadian rhythms. The brain has trouble adjusting when the time of day suddenly changes. The result is jet lag.

 

Conclusion

Researchers are considering time of days affects on body clocks in all aspects of health. This even includes the best time to have surgery on specific parts of the body. These studies may lead to new insights for a range of clock-related disorders, from insomnia and jet lag to diabetes.

Maintain a correct and regular schedule of activities to optimize your health and stay disease free.
