Why Is My Period Heavier at Night?

Night period guide

Quick answer

Your period often feels heavier at night because you lie down for hours without changing. Blood can collect while you sleep, then gush out when you stand up. If you have to get up at night to change your pad or tampon, that can be a sign of a heavy period, so tell your doctor.

Why is my period heavier at night?

A few things can make your period feel heavier at night. You lie flat for hours, so blood can collect inside. When you get up, it may come out in a rush.

You also go longer without changing. A pad or tampon that was fine by day can fill up by morning. And bleeding is often heaviest in the first 2 days of your period.

How to deal with heavy periods at night

  1. Change right before bed

    Start the night with a fresh pad, tampon or cup.

  2. Pick protection for long nights

    Overnight pads are longer than day pads. If you use tampons, the FDA says never to wear one for more than 8 hours.

  3. Add backup

    Wear period underwear with your tampon, cup or pad. Kischt's protective area runs up toward the back, for extra coverage when you lie down.

  4. Protect your bed

    Lay a dark towel under your hips. Keep a spare pair and a pad by the bed.

  5. Get up with a plan

    Head to the bathroom first thing in the morning. Blood that collected overnight may come out when you stand.

Overnight backup from Kischt

Kischt period underwear has three absorbent layers, made for heavier flow days. A moisture barrier inside helps stop leaks. The high waist and full back are made to feel secure without digging in.

On heavy nights, pair it with a tampon, cup or pad. How long it lasts depends on your flow, so check it while you learn how it works for you.
