To improve a woman’s fertility level, she must establish a healthy sleep pattern and get her circadian rhythm and hormonal levels in sync. The best part? Helping to increase your natural fertility could be as simple as turning off computers, cellphones, and TVs at least one hour before you plan to retire. Today’s woman often skimps on sleep due to increasing demands at home and work. When a woman’s body is deprived of rest, she can experience weight gain, mood disorders, and increased stress levels.
