Pregnancy Lifestyle Guide

Evidence-anchored pregnancy lifestyle guidance — travel, work, sleep, beauty, environment, and mental health by trimester. Sources: ACOG, NHS, CDC, NIOSH, EWG.

Every topic has trimester-specific pages — what changes in the first, second, and third trimester. Open any topic to read all three.

Mental Health

Anxiety, therapy, mindfulness, substance avoidance, peer support.

  • EncouragedMeditation and MindfulnessMindfulness-based interventions have RCT evidence for reducing prenatal anxiety, depression, and labor pain.
  • EncouragedTherapy and CounselingCBT and interpersonal therapy are first-line for perinatal anxiety and depression; medication is the second-line option, not the only option.
  • Generally avoidCannabis During PregnancyFDA, ACOG, and AAP all strongly recommend complete avoidance of cannabis and THC products in pregnancy.
  • EncouragedPeer Support GroupsPeer support — especially for loss, high-risk pregnancy, or specific conditions — reduces anxiety and isolation in RCTs.
  • EncouragedQuitting Smoking in PregnancyQuitting at any point in pregnancy improves outcomes; counseling and nicotine replacement therapy are effective.
  • Generally avoidVaping and E-CigarettesNicotine itself is harmful in pregnancy; vaping aerosol contains other concerning substances.

Sleep

Position, pillows, nighttime habits, restorative naps.

  • Generally safeSleep PositionLeft-side sleeping is preferred after 20 weeks; brief turns to back are not dangerous.
  • Generally safePregnancy PillowsBody pillows, wedge pillows, and pregnancy-specific pillows all help; type depends on individual comfort.
  • Generally safeFrequent Nighttime Bathroom TripsReduce fluids 1-2 hours before bed; full daytime hydration remains essential.
  • EncouragedNapping During PregnancyShort naps (20-30 min) help energy; very long daytime naps can disrupt nighttime sleep.

Work

Standing, sitting, night shifts, lifting, chemical exposure.

  • Generally safeStanding-Heavy WorkProlonged standing (>6 hours/day) is associated with increased preterm birth risk; modifications help.
  • Generally safeDesk and Computer WorkGenerally safe; ergonomics, frequent movement breaks, and good posture become essential as pregnancy progresses.
  • Limit + careNight Shift WorkRotating and night shifts are linked to increased preterm birth and miscarriage risk; modifications help.
  • Limit + careHeavy Lifting at WorkNIOSH provides pregnancy-specific lifting limits that decrease as pregnancy progresses.
  • Generally safeHigh-Stress WorkHigh occupational stress is linked to slightly elevated preterm birth risk; management strategies help.
  • Generally safeWork Chemical ExposureOSHA and NIOSH maintain pregnancy-specific exposure recommendations for many workplace chemicals.
  • EncouragedPaternity / Partner Leave PlanningPartner leave supports postpartum recovery, breastfeeding, and parental mental health.

Travel

Flying, road trips, international destinations, altitude.

  • Generally safeAir TravelGenerally safe through 36 weeks for uncomplicated pregnancies; DVT and airline policy are the main considerations.
  • Generally safeRoad TripsStop every 1-2 hours to walk; seatbelt properly positioned across pelvis and shoulder.
  • Generally safeInternational TravelGenerally OK in second trimester to safe destinations; Zika areas and remote medical access change the calculation.
  • Generally safeCruise TravelMost cruise lines restrict travel after 24 weeks; norovirus and limited medical care are the main concerns.
  • Generally safeHigh-Altitude TravelBelow 8,000 ft is generally fine; above 8,000 ft warrants gradual acclimatization or avoidance.
  • Generally avoidZika-Risk DestinationsCDC and WHO recommend pregnant people avoid travel to areas with active Zika transmission.

Beauty + Body

Skincare, hair treatments, sunscreen, nails.

  • Generally safeHair Dye and Color TreatmentMinimal scalp absorption; many providers and women choose to wait until second trimester.
  • Generally avoidKeratin and Hair Smoothing TreatmentsMany contain formaldehyde or formaldehyde-releasing chemicals; FDA has flagged inhalation risk.
  • Generally safeSpray Tan and Self-TannerDHA self-tanner lotion is safer than spray tan booths; FDA cautions against DHA inhalation.
  • Generally avoidLaser Hair RemovalLimited safety data; pregnancy pigmentation changes affect results.
  • Generally avoidBotox and Dermal FillersManufacturers and ACOG recommend deferring elective Botox and fillers during pregnancy.
  • Generally avoidRetinoids in SkincareTopical retinoids and oral isotretinoin are teratogenic and universally avoided in pregnancy.
  • EncouragedSunscreen Choice in PregnancySunscreen is critical to prevent melasma worsening; mineral sunscreens are preferred over chemical.
  • Generally safeNail Care and ManicuresNail polish is generally safe; salon ventilation matters more than at-home occasional use.

Environment

Cleaning products, paint, pesticides, pet contact, air quality.

  • Generally safeHousehold Cleaning ProductsMost household cleaners are safe with ventilation; never mix bleach with ammonia or acids.
  • Generally avoidPaint and Home RenovationLatex paint in well-ventilated areas is generally OK in later pregnancy; oil-based paints, lead paint, and strippers are not.
  • Generally avoidCat Litter and Toxoplasmosis RiskToxoplasma gondii can cause severe congenital infection; have someone else change cat litter when possible.
  • Generally safePesticides and Bug SprayDEET-based insect repellent is safe; broader pesticide applications warrant caution.
  • Generally safeHot Baths and Water TemperatureWarm baths (under 100°F) for moderate duration are fine; hot tubs and very hot baths can raise core temperature.
  • Generally avoidAir Quality and Wildfire SmokeWildfire smoke and high PM2.5 exposure are linked to preterm birth and low birth weight; HEPA filtration and N95 masks help.
  • Generally avoidMicrowaving Plastic ContainersBPA and phthalates can leach from plastic when heated; use glass or ceramic for hot food.
  • Generally safePets During PregnancyCats: avoid changing litter (toxoplasmosis). Dogs: continue normal interaction. Reptiles: avoid handling (salmonella).
