Don't let these four bad habits erode your immune system!

By: HSEclub NewsJun 27, 2025

The immune system is the loyal guardian of our body, always resisting the invasion of external pathogens; and the thyroid gland, as a key organ for regulating metabolism, plays a vital role in our physical health.

Especially for patients with thyroid disease, maintaining the health of the immune system is of paramount importance.

Four bad habits that can easily erode the immune system, everyone must pay attention to avoid!


◆ Lack of sleep: the "invisible killer" of the immune system


The importance of sleep

Sufficient sleep is a critical period for the body to recover and the immune system to repair itself. During sleep, the body will undergo a series of physiological adjustments, and immune cells will also get enough rest and repair. Long-term lack of sleep will gradually reduce the function of immune cells, and the body's resistance will also weaken, thereby increasing the risk of infection with various diseases.

Suggestions

  • Ensure sleep duration: Adults should ensure 7-9 hours of high-quality sleep every night, so that the body and immune system can be fully restored.
  • Develop regular habits: Maintain regular sleeping habits, try to go to bed and get up at the same time every day, and avoid staying up late. Regular work and rest can help adjust the biological clock and improve sleep quality.
  • Create a comfortable environment: Create a comfortable sleeping environment, such as maintaining a suitable temperature and light in the bedroom, and choosing soft and comfortable mattresses and pillows, which can help us fall asleep faster and improve the comfort of sleep.


◆ Unbalanced diet: "Nutrition gap" of the immune system


The importance of nutrition

A balanced diet is the basis for the normal functioning of the immune system, which can provide the immune system with necessary nutrients and energy. If the diet lacks important nutrients such as vitamins and minerals, the normal function of immune cells will be affected, resulting in a decrease in the body's resistance.

Suggestions

  • Eat more beneficial foods: Eat more foods rich in vitamins C, E and zinc, such as citrus fruits, nuts and seafood. The nutrients in these foods help to enhance the activity of immune cells and improve the body's immunity.
  • Maintain a diverse diet: Maintain a diverse diet, including vegetables, fruits, whole grains and high-quality protein. Different foods contain different nutrients, and a diverse diet can ensure that we take in comprehensive nutrition.
  • Reduce bad intake: Avoid excessive intake of processed foods and sugar. Processed foods often contain a lot of additives and preservatives, and excessive intake of sugar can also affect the body's metabolism and immune function.


◆ Lack of exercise: "lack of vitality" of the immune system


Benefits of exercise

A moderate amount of exercise is like injecting a dose of "vitality injection" into the immune system, which can enhance the activity of immune cells, promote blood circulation and metabolism, and allow all organs of the body to be better nourished. If you sit still for a long time, the body's blood circulation will slow down, and the function of the immune system will also decline.

Suggestions

  • Stick to daily exercise: do at least 30 minutes of moderate intensity exercise every day, such as brisk walking, jogging or swimming. These exercises can effectively improve cardiopulmonary function and enhance the body's resistance.
  • Combine strength training: In addition to aerobic exercise, you can also combine strength training to enhance muscle strength. The increase in muscle strength helps to increase the basal metabolic rate and further promote physical health.
  • Use fragmented time: Use fragmented time to do simple stretching activities to relieve the stiffness caused by long-term sitting. For example, stand up and move your body during work breaks, do some simple stretching exercises, and relax your body.


◆ Excessive stress: "emotional shackles" of the immune system


The impact of stress

Long-term mental stress is like an invisible shackle that releases a large amount of stress hormones. These hormones inhibit the function of the immune system, reduce the body's resistance, and increase the risk of illness.

Suggestions

  • Learn relaxation techniques: Learn relaxation techniques such as deep breathing, meditation, and yoga. These methods can help us relieve tension, relax the body and mind, and reduce the impact of stress on the immune system.
  • Maintain social relationships: Maintain positive social relationships and seek support from family and friends. Sharing your feelings and stress with relatives and friends can give us emotional comfort and reduce psychological burdens.
  • Rationally arrange life: Rationally arrange work and life to avoid overwork. Leave enough rest time for yourself to relax your body and mind.


◆ Special reminder: Patients with thyroid disease

Thyroid disease patients need to pay special attention to the above four aspects of health management. Abnormal thyroid function will directly affect metabolism and the immune system, so maintaining a healthy lifestyle is crucial for patients with thyroid disease.


◆ Summary

By improving sleep, eating a balanced diet, exercising moderately and reducing stress, we can effectively enhance the function of the immune system and reduce the risk of disease. Thyroid patients should pay more attention to these details, starting from the little things in life, maintaining the overall health of the body, and allowing the immune system to better "stand guard" for us.
