During this pandemic, there are many changes in daily activities such as diet, whereas maintaining a balanced diet and nutritious food consumption is very important in increasing immunity and reducing the risk of exposure to infectious diseases. Mental health disorders are also commonly found where the disorder is triggered by various things such as difficulty to meet with friends and family and feeling lonely. However, mental health topic is sometimes still considered taboo due to the lack of education about mental health in Indonesia. To deal with this situation, we took the initiative to conduct education. The purpose of this education is to increase knowledge and awareness in the younger generation regarding the importance of maintaining mental and immunity. The educational activities carried out at senior high school 1 Malang are integrated to support the achievement of the 3rd SDGs.
