How to adjust the biological clock?

Adjusting the biological clock is a step-by-step process that requires attention from many aspects such as light exposure, work and rest, diet, and exercise. The main contents include:Regular schedule(fixed wake-up and bedtime),Light adjustment(Using natural light or artificial light sources),Diet control(Avoid eating spicy foods at night),moderate exercise(Daytime activities promote nighttime sleep) andpsychological adjustment(Reduces bedtime anxiety). Among them, regular work and rest and light adjustment are the key, and other methods are auxiliary means.

Regular work and rest are the basis for adjusting the biological clock.Waking up and going to bed at the same time every day, even on weekends, will help stabilize the melatonin cycle in your body. It is recommended to avoid using electronic devices 1 hour before going to bed because blue light inhibits melatonin production and affects falling asleep. If you have trouble falling asleep, try meditation or deep breathing to relax. It may be difficult at first, but after 1-2 weeks, your body will gradually adapt to the new rhythm.

Light regulation can directly affect the biological clock.Exposure to natural light for more than 30 minutes in the morning can help the brain wake up and advance the biological clock; while reducing exposure to strong light in the evening can help sleep at night. For people working night shifts or across time zones, you can uselight therapy lamp(Such as Philips Hue, Osram and other brand products) simulate the sunlight effect. Research shows that light therapy can improve seasonal affective disorder and sleep disorders (Source: American Academy of Sleep Medicine).

Diet and exercise are equally important in regulating the biological clock.Dinner should be light and avoid caffeine and alcohol; foods rich in tryptophan (such as milk, bananas) can promote sleep. 30 minutes of aerobic exercise (such as brisk walking, yoga) during the day can improve sleep quality, but avoid strenuous exercise 3 hours before going to bed. In addition, you can consider supplementing melatonin (such as Natrol, GNC and other brands) in the short term, but you need to follow your doctor's advice. Long-term dependence may disrupt your own secretion.

Only comprehensive adjustments can stabilize the biological clock in the long term.Combining regular work and rest, light management, healthy diet and moderate exercise, most people can rebuild their biological clock within 4-6 weeks. If long-term insomnia or shift work cause serious problems, it is recommended to consult a professional doctor. Harvard Medical School research points out that biological clock disorders may increase the risk of chronic diseases, so timely intervention is crucial (Source: Harvard Health Publishing).
