(HealthDay News) -- Heat rash is a common problem among infants, appearing as small red bumps or blisters on the skin caused by sweating.

The U.S. National Library of Medicine offers these suggestions to protect your baby from heat rash:

• The goal is to keep baby cool and dry. During hot or humid weather, dress baby in lightweight, cool and absorbent cotton clothing.
• Keep baby in air-conditioned areas, or use a light fan. But position it far enough away that only a light breeze can be felt.
• Avoid using powders, creams and ointments on baby's skin. These products won't prevent heat rash and may actually block the pores.
