Lifestyle changes that can boost energy levels include maintaining a balanced diet, prioritizing sleep, and staying physically active. Consuming a variety of whole foods, such as fruits, vegetables, and whole grains, provides the nutrients necessary for sustained energy. Establishing a consistent sleep schedule and aiming for 7-9 hours of quality sleep each night can significantly improve fatigue levels. Incorporating regular physical activity, even short walks or stretches throughout the day, enhances circulation and reduces feelings of lethargy. Additionally, managing stress through relaxation techniques can also contribute to higher energy levels.
