Sleep After a Late Night Dawat

Plan your night

Enter the time it ended and your alarm. The planner adds the wait you choose before lying down and shows the alarm times that end a sleep cycle.

What to do tonight, in order

You are home, it is late and your stomach is full. The goal is not perfect sleep. It is a reasonably comfortable night and a quick recovery tomorrow.

1. Stay upright for a while. Sit, stand or walk slowly indoors for 30 to 60 minutes. Many digestive health guides suggest leaving 2 to 3 hours between a big meal and lying flat.
2. Drink water in small sips. Avoid another cup of strong tea, coffee or a cold fizzy drink.
3. Skip more food and sweets. If you are hungry again, choose something small and plain, such as a banana or a few plain biscuits.
4. Change into loose clothes and wash your face and hands. A warm shower can help you relax.
5. When you do lie down, raise your head and chest a little with extra pillows and try your left side if reflux or gas is a problem.
6. Set an alarm for a sensible wake time. Do not plan a huge sleep in.

When will you wake up if you go to bed now

Use this table to see the wake time for each number of sleep cycles. It assumes 15 minutes to fall asleep and cycles of about 90 minutes.

If you have to be up at 8:00 AM and you reach bed at 1:00 AM, five cycles would end at 8:45 AM, so four cycles at 7:15 AM is the closer choice. Try the sleep now calculator for the exact time, and the late dinner sleep calculator to see when your stomach is ready.

Why a late heavy dinner hurts sleep

Digestion does not switch off at night, but lying flat and eating a large meal together make reflux and fullness more likely. Rich, oily, spicy or sweet food can linger longer in the stomach. Fizzy drinks add gas. Tea and coffee add caffeine, which has a half life of about 5 to 6 hours in many adults and can delay sleep even when you feel tired. A late social evening also means brighter light, talking and excitement, which keep the body clock awake.

The result is often a longer time to fall asleep, lighter sleep and more waking at night. It is annoying but not dangerous for most healthy adults. The same pattern is covered on the heavy meal page and the late meal page.

Tomorrow: the reset plan

• Wake within about one hour of your normal time. A very late wake time shifts your body clock later.
• Get daylight as soon as you can. Morning light is the strongest cue for your body clock.
• Eat a light, regular breakfast and drink water. Skip the urge to make up for a heavy night with a giant meal.
• Take a 10 to 20 minute walk. Gentle movement helps digestion for many people.
• Keep coffee to the morning. Stop caffeine at least 8 to 10 hours before your bedtime, see the caffeine half life calculator.
• If you are very tired, a 20 minute nap before about 3 PM is fine. Longer naps can delay tonight. See the nap calculator.
• Go to bed 30 to 60 minutes earlier tomorrow night, and use the bedtime calculator for the exact time.

One late night costs a little sleep and is easy to recover. Repeated late dinners are what build sleep debt, so check the total with the sleep debt calculator.

Planning ahead for the next dawat

You do not have to skip family meals. A few small choices make the next night easier.

• Eat a small snack earlier so you are not starving and overeating at 11 PM.
• Choose a smaller plate of the heaviest dishes, and take dessert in a small portion.
• Drink water between cups of tea.
• Leave when you can, and plan the morning so you are not forced into a short night.
• Take a short walk after the meal before the drive home.

Families in Pakistan, India and the Gulf often eat very late, especially during weddings and in Ramadan. See the Pakistan guide, the Ramadan guide and sleep after a wedding reception.
