The experience of persistent dryness across the body is a frequently reported symptom during pregnancy. This feeling of parched skin, eyes, and mouth is a direct result of the profound physiological adjustments the body undergoes to support a developing fetus. Recognizing this dryness as a natural consequence of biological changes is the first step toward finding effective relief.
Systemic Causes of Pregnancy-Related Dryness
The body’s fluid balance shifts dramatically during pregnancy, driven by hormonal signals and a massive increase in blood volume. These systemic changes mean that moisture is diverted from peripheral tissues, leading to generalized dryness.
Hormonal fluctuations, particularly the rise in progesterone and estrogen, alter the function of sebaceous glands that produce the skin’s natural oils. This shift can slow oil production, compromising the skin’s barrier and increasing water loss. The body also prioritizes fluid for the placenta, amniotic fluid, and the mother’s increased blood supply.
Maternal blood volume can increase by 30% to 45%, requiring a substantially greater total fluid intake. If fluid intake does not meet this demand, relative dehydration can occur, pulling moisture away from the skin and mucous membranes. The body’s metabolic rate also accelerates, leading to increased heat production and more fluid loss through perspiration and ventilation.
Managing Dryness in Specific Body Areas
Systemic changes in fluid and hormones manifest differently across the body, requiring targeted management strategies for comfort.
Skin
Generalized dryness, sometimes accompanied by intense itching (pruritus gravidarum), results from a compromised skin barrier and stretching skin. To minimize moisture loss, limit showers to lukewarm temperatures and avoid harsh, alkaline soaps or fragranced body washes. Immediately after bathing, while the skin is still damp, pat dry and apply a thick emollient to seal in surface water.
Eyes
The eyes are sensitive to hormonal shifts, which can lead to dry eye syndrome and contact lens discomfort. Estrogen and progesterone influence the meibomian glands, which produce the oily layer of the tear film that prevents rapid evaporation. If this oily layer is reduced, tears evaporate too quickly, causing irritation, grittiness, and blurred vision. Relief can be found by using preservative-free artificial tears and reducing extended screen time, which decreases the natural blink rate.
Mouth and Nasal Passages
Dry mouth (xerostomia) is common due to dehydration and mouth breathing caused by hormonal nasal congestion. Hormonal changes can reduce saliva production, increasing the risk of tooth decay since saliva naturally neutralizes acids. To combat this, chew sugar-free gum or suck on sugar-free candies to stimulate salivary flow, and maintain oral hygiene with alcohol-free mouthwash. For dry nasal passages, which can increase the risk of nosebleeds, a saline nasal spray or a humidifier can help moisturize the mucous membranes.
Immediate Relief and Prevention Strategies
The fundamental strategy for combating pregnancy-related dryness is maintaining optimal internal hydration. Pregnant individuals need a higher volume of fluids, often aiming for 8 to 12 glasses of water daily (64 to 100 ounces). Integrating electrolyte-rich foods, such as fruits and vegetables with high water content, helps the body retain necessary fluids.
For topical relief, select products with specific moisturizing ingredients to improve skin comfort. Look for hyaluronic acid, which draws moisture into the skin, and ceramides, which help repair the skin’s moisture barrier. Avoid ingredients absorbed systemically in high concentrations, such as retinoids, high-dose salicylic acid, and hydroquinone.
Adjusting the immediate environment also makes a difference, particularly in dry climates or during winter months. Using a cool-mist humidifier in the bedroom adds moisture to the air, soothing dry skin, eyes, and nasal passages while sleeping. While most dryness is harmless, severe, unrelenting itching, especially on the palms and soles of the feet, requires immediate medical attention as it can signal Intrahepatic Cholestasis of Pregnancy.
