In Korea, the four seasons are distinct. These seasonal changes can have various effects on our body and mind. Therefore, it is important to know how to manage your health according to the seasons. First is spring. In spring, pollen and allergies can be problematic. For this, a diet with olive oil and ginger is recommended. According to research, these foods have natural antihistamine effects and help alleviate allergy symptoms. Additionally, light aerobic exercise can help strengthen the immune system. In summer, dehydration and heatstroke are major issues. It is good to drink more than 2 liters of water a day and frequently eat fruits and vegetables rich in moisture, such as watermelon and cucumber. Instead of indoor exercise, try swimming or running in the morning or evening. According to a 2015 World Health Organization (WHO) report, exercising outdoors increases vitamin D synthesis due to the effects of sunlight, which enhances immunity. In autumn, it is important to adopt habits that boost immunity. Consume fresh seasonal fruits and vegetables, and add nuts rich in zinc. Reducing stress through meditation is also important. Even meditating for just 10 minutes a day can bring peace of mind. In winter, colds and flu are prevalent. Frequently consume oranges or kiwis rich in vitamin C. Also, strength training that can be done indoors is recommended. Research suggests that building muscle in cold weather helps maintain body temperature and reduces the likelihood of catching a cold. Managing health according to each season is very important for improving our quality of life. Try making these methods part of your daily habits. You can continue a healthy lifestyle by recording small changes in your daily life through the 'Daily Certification' app.
