Pregnancy Advice in a Heatwave
Daisyscan – Here to Support You
Pregnancy naturally makes you feel warmer due to hormonal changes and increased blood flow. As your bump grows, it’s normal to feel even hotter and more uncomfortable. During a heatwave, this can become especially challenging, increasing the risk of dehydration, fainting, heat exhaustion, and heatstroke.
Stay Hydrated
Drink regularly throughout the day—aim for at least 1.6 litres (6–8 medium glasses), more in hot weather. Water is best, but all fluids count. Try to limit caffeine and sugary drinks. Dehydration is a risk, particularly if you're experiencing pregnancy sickness. Signs include thirst, dark urine, dizziness, tiredness, a dry mouth, and weeing fewer than four times a day. If concerned, speak to your GP, call NHS 111, or contact your maternity team.
Keep Cool
Avoid going out between 11am and 3pm when the sun is strongest. Stay in the shade, wear a wide-brimmed hat and sunscreen, and opt for loose, light cotton clothing. At home, close curtains during the day and open windows at night. Use fans, take cool showers, and keep a cold drink nearby.
Watch for Heat Exhaustion
Signs include tiredness, dizziness, nausea, fast breathing, or intense thirst. Move to a cooler place, remove excess clothing, and cool your skin. If symptoms persist after 30 minutes, seek urgent medical help, as this could be heatstroke.
Swollen Hands and Feet
Swelling is common, but sudden or severe swelling—especially with a headache, vision changes, or pain—could be pre-eclampsia. Contact your maternity unit immediately.
