To improve sleep, wake up at the same time every day, get morning daylight, stop caffeine at least 6 hours before bed, keep your bedroom dark, quiet and cool, and follow a 30-minute screen-free wind-down. Adults need 7 or more hours a night. If poor sleep lasts for months, cognitive behavioural therapy for insomnia (CBT-I) works better than sleeping pills.

How much sleep do you need?

The American Academy of Sleep Medicine and the Sleep Research Society recommend that adults sleep 7 or more hours a night regularly. Regularly sleeping less is linked with weight gain, diabetes, high blood pressure, heart disease, depression and more accidents. Sleep quality matters too: waking up refreshed is a good sign.

15 tips to improve sleep quality

Build a steady rhythm

1. Wake up at the same time every day, including weekends. A fixed wake time is the strongest anchor for your body clock.
2. Get daylight within an hour of waking. 10–20 minutes outside, or near a bright window, helps set your body clock.
3. Go to bed when sleepy, not just tired. Lying in bed wide awake trains your brain to link bed with being awake.
4. Keep naps short: 20–30 minutes, before about 3 pm.

Watch what you eat and drink

5. Stop caffeine at least 6 hours before bed. In a 2013 study, caffeine taken 6 hours before bedtime still cut sleep by more than an hour. This includes chai, coffee, cola, energy drinks and some pre-workout supplements.
6. Avoid alcohol close to bedtime. It may make you drowsy but disturbs sleep later in the night.
7. Finish dinner 2–3 hours before bed and keep it light, especially if you get acidity.
8. Avoid nicotine, which is a stimulant.

Fix your bedroom

9. Make it dark: curtains that block light, or an eye mask.
10. Keep it quiet and cool: earplugs or a fan for background noise; a cooler room is usually better for sleep.
11. Use your bed only for sleep (and intimacy), not work, TV or scrolling.

Wind down your mind

12. Screens off 30–60 minutes before bed. Phones keep your brain alert with messages, reels and bright light.
13. Follow a 30-minute wind-down routine: a warm bath, light stretching, reading a paper book, or slow breathing.
14. Write down worries and tomorrow’s to-do list earlier in the evening so they don’t keep you up.
15. If you can’t sleep in about 20 minutes, get up. Sit in dim light doing something calm, and return to bed when sleepy.

A simple 30-minute bedtime routine

Time before bed	What to do
60 min	Phone on silent/charging outside the bedroom; dim the lights
45 min	Warm shower or wash; brush teeth
30 min	Light stretching or 5 minutes of slow breathing (inhale 4, exhale 6)
20 min	Read a paper book or listen to calm audio
0 min	Lights off, cool dark room

Does exercise help you sleep better?

Yes. Regular physical activity is linked with better sleep quality. Try to be active most days, such as a brisk daily walk or Surya Namaskar in the morning. If intense workouts late at night keep you awake, move them earlier.

What about sleep supplements?

Melatonin may help with jet lag or shifted sleep timing, but it isn’t a first-line fix for long-term insomnia, and doses in supplements vary. Many “sleep formula” products mix several ingredients with little evidence. Read our Relaxium Sleep review before buying one, and talk to your doctor, especially if you take other medicines, are pregnant, or are buying for a child.

When to see a doctor about sleep

Trouble sleeping at least 3 nights a week for 3 months or more (possible chronic insomnia).
Loud snoring, choking or gasping in sleep, or someone notices you stop breathing (possible sleep apnea).
Feeling very sleepy in the daytime or dozing off while driving.
Strong urge to move your legs at night (restless legs).
Poor sleep along with low mood, anxiety or ongoing pain.

For chronic insomnia, the American College of Physicians recommends cognitive behavioural therapy for insomnia (CBT-I) as the first treatment for adults. It teaches sleep scheduling, stimulus control and ways to handle racing thoughts. Sleeping pills are used only short-term in selected cases.

Frequently asked questions

How can I improve my sleep quality naturally?

Wake up at the same time daily, get morning sunlight, avoid caffeine for 6 hours before bed, keep your room dark, quiet and cool, and stop screens 30–60 minutes before sleep. Regular exercise and a light, early dinner also help. Most people notice better sleep within 2–3 weeks.

How many hours of sleep do adults need?

Adults need 7 or more hours of sleep a night on a regular basis, according to the American Academy of Sleep Medicine and Sleep Research Society. Some people need more, especially after illness or sleep loss. Regularly getting less than 7 hours is linked with health problems.

How can I fall asleep faster?

Go to bed only when sleepy, keep the room dark and cool, and do a calm 30-minute routine without your phone. Slow breathing, with a longer exhale, can help. If you’re still awake after about 20 minutes, get up and do something relaxing until you feel sleepy.

How do I fix my sleep schedule?

Choose a fixed wake-up time and stick to it every day, even after a bad night. Get daylight soon after waking and avoid long naps. Move your bedtime earlier by 15–30 minutes every few days. Your body clock usually adjusts within 1–2 weeks.

Does drinking chai at night affect sleep?

It can. Chai contains caffeine, and a 2013 study found caffeine taken even 6 hours before bed reduced sleep by more than an hour. If you have trouble sleeping, have your last cup of chai or coffee by early afternoon, or switch to decaf or herbal tea.

When should I see a doctor for sleep problems?

See a doctor if you struggle to sleep 3 or more nights a week for 3 months, snore loudly with gasping or choking, feel very sleepy during the day, or have poor sleep with low mood. Cognitive behavioural therapy for insomnia (CBT-I) is the recommended first treatment.
