Do you feel:
- You cannot stay asleep at night?
- You have a slow start in the morning?
- Afternoon fatigue?
- Waking up tired even after getting six or more hours of sleep?
- Under a high amount of stress?
If you are experiencing any of these situations, then it might be due to your melatonin and cortisol levels affecting your body and circadian rhythm.
Across the world, millions of people have trouble sleeping. In the United States, there are roughly about 50-70 million people who have a poor quality of sleep. When a person has slept for less than eight hours, they become tired, and many problems can come to them, especially if their lives are hectic. With a hectic lifestyle and poor sleep, it can cause the body to have low energy to get any task done, the cortisol stress hormone will be raised, and diseases like high blood pressure and diabetes can cause problems that can be chronic if it is not treated.
In functional endocrinology, melatonin and cortisol are hormones that the body produces naturally. The cortisol hormone or the stress hormone helps the body be in a state of “fight or flight” mode, which can be a good thing for anyone who is doing a project or going for a job interview. Although when cortisol hormone levels are high, it can lead the body to have complications like inflammation, chronic oxidative stress, and high blood pressure.
The Melatonin Circadian Rhythm
With the melatonin hormone, this hormone tells the body when it is time to sleep. Sometimes though, people do have a hard time sleeping, and taking melatonin supplements can actually relax the body and thus making the person fall asleep. Since the pineal gland produces melatonin from the brain, it can also be found in the eyes, the bone marrow, and the gut to relax the body and making the person fall asleep naturally. Some studies show that the circadian rhythm of the pineal gland that is producing melatonin. By doing this, the research shows that the administration of melatonin can:
- One: induce sleep on individuals who have trouble falling asleep.
- Two: inhibits the body to wake up naturally from the circadian pacemaker.
- Three: shift the circadian biological clocks to increase sleep intake when a person is trying to sleep at an earlier time to get the full eight-hour benefits of sleep.
When a person is working at a 9 to 5 job, they are rising with their bodies and relaxing their bodies after a hard day at work. Studies found out that the melatonin and cortisol hormones help regulate the 24-hour pattern of the body’s function and responses tremendously. With the body’s hormone production cycle, it can be disturbed if the person is staying awake late at night or sleeping during the day. When this happens, the person can get disruptive disorders like mood swings, dizziness, be irritable and depressed, and have metabolic disorders. Not only that, but the body’s immune system and its endocrine system can also be damaged as well, causing the body to be a host to infections and diseases.
There have been more studies on the circadian rhythms in the body, as the studies show how people who work in the night shift have been associated with a vast number of adverse health problems that attack the cardiovascular and gastrointestinal system as well as disturbing the metabolic system. Anyone who has worked the night shift has to change their sleep schedule and adapt to the rapid reorientation in their sleep/wake schedule to go to work and do their job. Since everyone is working at a shift schedule, it can be stressful and can affect a worker’s body performance as well as affecting melatonin and cortisol secretion.
Ways To Support Cortisol and Melatonin
Surprisingly though, there are ways to lower cortisol levels and make sure that melatonin levels are working correctly for the body to function. For cortisol levels to be lowered, a person should do meditative practices, find an enjoyable hobby, and, most importantly, try deep breathing exercises to relax the body from unwanted stress. With deep breathing exercises, it can help the body to release any tension that a person is holding, and the muscles in the body began to relax, and the blood starts to flow. With the melatonin levels, they work together with the body’s circadian rhythm and make sure the body knows when it is time to wake up, sleep and eat. The melatonin hormone can also help regulate the body’s temperature, blood pressure, and hormone levels to make sure it is functioning correctly. When there are high levels of these systems, it can cause the body to develop chronic illnesses and harm the body in the process.
Research shows that melatonin hormones can bind to neurological receptors in the body, thus promoting relaxation. Since melatonin binds to neurological receptors, it can also reduce nerve activity and dopamine levels to make the eyes heavy, thus making the person fall asleep.
With the body being able to naturally produce melatonin and cortisol levels to make sure that the body does not get overly stressed throughout the entire day. Since melatonin is partnered with the body’s circadian rhythm, the body knows when to stay up and fall asleep. Since everyone has a hectic schedule, it is essential to take time and relax and get on a healthy sleep schedule so the body can be healthy and functioning.
