Stimulate adrenaline secretion

People's mood is very important, because usually work pressure or other reasons may cause people to be in a bad mood. When people are in a bad mood, they will feel that life is meaningless. Over time, their bodies will be seriously affected. Health will also be affected. So people should always be in a happy mood. So how do you stimulate the secretion of adrenaline?

1. Spend more time with friends

When you are with friends, your immune system will be in good condition because of the friendship and social recognition. To prove this point, researchers at the Paris Center for Mental and Physical Health exposed participants to the cold virus and then monitored their social interactions. The results showed that the more time people spent with friends, family and colleagues, the less likely they were to catch a cold. At the same time, physical contact such as hugging and caressing can make the body's immune cells more active.

2. Listen to your favorite music

Listening to music can also activate the human immune system, but it must be music that you really like. "The same piece of music may sound like heavenly music to some people, but may sound like noise to others," says Dr. Burke. "The key is to choose music that soothes your soul." Good music, like food and sex, can stimulate the part of the brain that feels pleasant, thereby improving immunity.

3. Reduce noise

Not only does noise damage people's hearing, it can also cause muscle tension, accelerated heart rate, blood vessel constriction and digestive system discomfort - the same as the body's reaction when it is frightened or stressed. Long-term exposure to noise can cause adverse changes in blood pressure, cholesterol levels and immune function. A study by Cornell University in the United States found that women who work in noisy environments release more adrenaline and are more likely to suffer from heart disease than women who work in quiet offices. However, sounds that make people feel uncontrollable, such as car horns and dog barking, are more harmful to the human body. Therefore, people should try to control the sounds in their surroundings, even if it means wearing headphones or asking restaurant owners or gym managers to turn down the volume of the speakers.

4. Maintain a positive attitude

The immune system is influenced by our thoughts and feelings, so we should maintain a positive attitude. Researchers at the Mayo Clinic in the United States found that people who were optimistic when they were young lived 12 years longer than pessimistic people. Recently, psychologist Anna L. Maslander from the University of Pittsburgh Medical Center also found in a study that people who are negative, depressed, and easily stressed are much less resistant to the hepatitis virus than their optimistic peers.

5. Eat a healthy diet

A deficiency in any one nutrient can lead to frequent and long-term illness. When a person feels hungry, the body secretes adrenaline; if the body weight decreases by more than 850g per week, the T cells that resist disease and foreign viruses will be suppressed. In this regard, experts recommend that when combining meals, you should eat some foods containing unsaturated fatty acids, consume enough protein, eat more fruits and vegetables, and drink more juice and boiled water. However, health supplements that claim to boost immunity do not seem to be very effective.

6. Laugh out loud

Anger and sadness can damage your health, while laughter has the opposite effect. Laughter can make immune cells more active. To test the idea, Burke showed students a comical video and measured their immune system responses. The results showed that even just hearing a humorous joke can improve immunity. Additionally, laughter improves circulation and digestion, lowers blood pressure, and relieves muscle tension.

7. Use your brain more

Positive thinking activities can improve immunity. Marian Diamond, a neuroscientist at the University of California, Los Angeles, found in her research that playing bridge can stimulate the activity of immune cells. Her research revealed for the first time a close connection between the parts of the brain responsible for planning, memory, judgment, abstract thinking and the immune system. "Any mental activity that uses the intellectual function of the brain is good for immunity," Diamond said.

8. More activities

Regular, long-term moderate exercise can enhance the body's resistance. "Physical exercise is not only beneficial to the cardiovascular system, it is also good for improving mood and reducing stress," Burke said. However, the intensity of the activity should be appropriate. If you feel strenuous and beyond your normal tolerance, you should adjust it in time.

9. Learn to relax

Stress causes the body to secrete steroid hormones and adrenaline, which slow down the immune system's response. This explains why people are particularly prone to catching colds when they are under stress, such as facing final exams or experiencing an emotional crisis. In addition, the anxiety caused by stress can also reduce the body's resistance. Regularly practicing relaxation techniques, such as aerobic exercise and gradual relaxation of muscles throughout the body, can inhibit the release of stress hormones and enhance immune function.

10. Turn off the lights

The human body produces melatonin, which fights off disease, only in darkness. Lack of sleep or prolonged exposure to light at night will reduce the release of melatonin and increase the secretion of estrogen, which makes it easy to develop breast cancer. Several recent studies have shown that women who work night shifts have a 60% risk of breast cancer, and women who like to keep their bedroom lights very bright have an even higher risk of breast cancer. The incidence of breast cancer in blind women is 20%-50% lower than that in normal women. Even dim light sources like bedside alarm clocks and night lights can inhibit the release of melatonin. Therefore, the darker the bedroom, the better.

A hormone secreted by the human body. When people experience certain stimuli (such as excitement, fear, tension, etc.), this chemical is secreted, which can speed up their breathing (provide a large amount of oxygen), accelerate their heartbeat and blood flow, and dilate their pupils, providing more energy for physical activities and making reactions faster. Adrenaline is a hormone and neurotransmitter released by the adrenal glands. Adrenaline increases the heart's contractility, dilates the blood vessels in the heart, liver, tendons and bones, and constricts the blood vessels in the skin and mucous membranes. It is essential for saving dying people or animals.
