Write 3 key points about maintaining a healthy lifestyle.
1. **Physical activity**: Regular exercise is crucial for maintaining a healthy lifestyle. It is recommended to engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity per week. This can help improve cardiovascular health, build muscle and bone strength, and boost overall physical and mental wellbeing.
2. **Balanced diet**: Eating a nutritious, well-balanced diet is also important for maintaining good health. This means consuming a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats, while limiting processed and junk foods. A healthy diet provides essential vitamins, minerals, and nutrients to keep the body functioning properly.
3. **Rest and stress management**: Getting enough sleep and managing stress levels is also important for overall health. Adults should aim for 7-9 hours of quality sleep per night, and practice stress-reducing techniques such as meditation, deep breathing or exercising. This can help improve mood, boost immune function, and reduce the risk of chronic health conditions.
