(HealthDay News) -- Hot flashes are a common symptom for menopausal women.

The earlier in life hot flashes begin, the longer they may last, the U.S. National Institute on Aging says.

The agency suggests how to manage hot flashes:

• Dress in layers, which can be removed when hot flashes begin.
• Carry a portable fan.
• Avoid alcohol, spicy foods and caffeine, which can worsen menopausal symptoms.
• If you smoke, quit.
• Maintain a healthy weight.
