1. Nutritional Needs: Women over 50 should focus on meeting their nutritional needs for better health and increased resistance. 

A balanced diet of fruits, vegetables, and meats is important for organ function and disease prevention. It's crucial to control food intake and avoid high-calorie foods to protect the digestive system and manage weight. 

2. Sleep Requirements: Adequate sleep is essential for women's health. It improves mental sharpness, resistance, and hormone levels. Lack of sleep can lead to gray hair, facial blemishes, and wrinkles. However, longer sleep doesn't always mean better sleep. 

Excessive sleep without enough physical activity can be detrimental.

Meeting the body's sleep requirements by aiming for seven to eight hours per day promotes women's health effectively.
