If you've experienced burnout, your body may be in need of attention. This is why it's important to think about the basics of good health and well-being.
Start by getting plenty of exercise . Countless studies have shown that this offers many physical and mental benefits; not only does regular exercise help reduce stress, but it also boosts your mood, improves your overall health, and enhances your quality of life.
Next, make sure that you're getting enough sleep , eating well, and drinking plenty of water throughout the day. These might sound obvious, but busy professionals often ignore their most basic needs. Instead, they take care of others and their responsibilities far more than they take care of themselves. This can contribute to burnout.
