What is safe in pregnancy: Practical guidance and clear boundaries

Pregnancy involves changes to your routine, but most of everyday life remains wonderfully ordinary. However, the internet often bombards expectant parents with contradictory, anxiety-inducing restrictions. While the true list of necessary precautions is much shorter than lifestyle forums suggest, the boundaries that do exist are medically grounded and protect you and your developing baby.

Here is a clear, evidence-based guide to what to avoid, what to limit, and what is safe to enjoy.

1. Food safety: Preventing infections

Hormonal changes naturally soften your immune system, making you slightly more vulnerable to foodborne illnesses:

• Avoid Listeria risks: Listeria monocytogenes can cross the placenta. Avoid unpasteurized milk and soft cheeses made from raw milk (such as unpasteurized brie, camembert, and blue cheeses—unless baked until steaming and bubbling hot throughout). In Iceland, take caution with cold-smoked or cured fish (grafinn lax), raw shellfish, and unheated deli meats (hangikjöt or cured ham) unless they are thoroughly cooked.
• Avoid Toxoplasmosis risks: Cook all meats (especially poultry, pork, and minced meat) thoroughly with no pink remaining. Wash all salads, vegetables, and fruit thoroughly to remove soil traces. Wear gloves when gardening and avoid changing cat litter trays (ask a partner or use gloves and wash hands thoroughly).
• Avoid excess Vitamin A and heavy metals: Avoid liver and liver products. Cod liver oil (lýsi) is a good source of vitamin D and omega-3 fatty acids in pregnancy, but limit it to one teaspoon (5 ml) a day and do not also take a multivitamin containing vitamin A (retinol). Avoid predatory fish high in mercury (such as shark, swordfish, and fresh tuna steaks; canned light tuna is acceptable in moderation).
• Raw eggs: Avoid foods containing raw or lightly cooked eggs unless they are pasteurized.

2. Alcohol, smoking, and nicotine

• Alcohol: There is no known safe amount and no safe time to consume alcohol during pregnancy. Alcohol crosses the placenta freely and can cause Fetal Alcohol Spectrum Disorders (FASD). Complete abstinence is the safest choice from conception through birth.
• Smoking and Vaping: Nicotine constricts placental blood vessels, reducing vital oxygen and nutrient transfer to your baby. It substantially raises the risk of low birth weight, premature birth, placental abruption, and stillbirth. Seek free cessation support through your midwife or health clinic.

3. Medications and supplements

• Never alter medications alone: Always consult your midwife or doctor before starting, stopping, or changing any prescription medicine, over-the-counter drug, or herbal remedy.
• Pain relief: Paracetamol is the preferred first-line pain reliever in pregnancy when clinically necessary, taken at the lowest effective dose for the shortest time. Avoid NSAIDs (like Ibuprofen and Naproxen), especially during the third trimester, as they can cause serious complications with fetal blood circulation and amniotic fluid levels.
• Supplements: Take a daily supplement of 400 mcg of folic acid during the first 12 weeks, and ensure your daily intake includes Vitamin D, as recommended by Icelandic health authorities.

4. Caffeine

You do not need to give up your morning coffee, but moderation is advised. Limit caffeine intake to under 200 mg per day (roughly equivalent to 1–2 mugs of filter coffee or 2–3 cups of tea). Remember that energy drinks, cola, and dark chocolate also contain caffeine.

5. Hot tubs (Heitir pottar), saunas, and geothermal pools in Iceland

Geothermal baths are an integral part of Icelandic life. While normal swimming in standard heated pools is one of the best pregnancy exercises, hot tubs and saunas require caution:

• Maternal core body temperature should not rise above 38.9°C (102°F), especially during the first 12 weeks, as maternal overheating (hyperthermia) is linked to neural tube defects.
• Stick to cooler tubs (below 38°C / 100°F).
• Keep your chest and arms above water, limit soaks to 10–15 minutes, and get out immediately if you feel dizzy, overheated, or start sweating profusely.

6. Exercise and physical activity

Staying active improves stamina for birth, reduces back pain, and lowers the risk of gestational diabetes and pre-eclampsia:

• Safe and encouraged: Walking, prenatal yoga, swimming, stationary cycling, and moderate strength training.
• Avoid: High-impact activities with a risk of hard falling or abdominal trauma (downhill skiing, horse riding, contact sports, gymnastics) and scuba diving.

Where to check specific foods and medicines in Iceland

If you are unsure about a specific food or medicine, check the official Icelandic safety registries:

• Food guidelines: Consult the Directorate of Health (Embætti landlæknis) or the Icelandic Food and Veterinary Authority (MAST.is).
• Medicines in pregnancy: Check with your community midwife, consult Heilsuvera.is, or ask your local pharmacist.
