Why Do People in Different Countries Have Different Sleep Habits?

Sleep is a universal human need, but how people sleep varies significantly across cultures and countries. Cultural values, climate, work schedules, and historical traditions all influence sleep habits around the world. For example, countries that emphasize worker productivity often see their citizens getting less rest, while others prioritize relaxation and midday naps.

Global Sleep Rituals and Cultural Influences

Many cultures incorporate unique rituals into their bedtime routines. For instance:

• In Mexico and Botswana, people often include prayer or meditation before sleep.
• Some hunter-gatherer communities in Botswana do not follow strict sleep schedules and may sleep at various times, even during the day or late at night.

Japan: Sleep and Social Values

While Western countries often recommend eight to nine hours of sleep per night, this standard does not apply everywhere. In countries with limited access to electricity, people may sleep soon after sunset and wake at sunrise. Artificial lighting and climate also shape sleep patterns; for example, people in tropical regions often rise earlier than those in colder climates.

Cultural roots play a significant role in sleep habits. These include:

• Duration of sleep
• Where people sleep and baby sleeping practices
• Attitudes toward napping

In Japan, falling asleep at work, known as "inemuri," is seen as a sign of dedication and hard work.

Scandinavia: Outdoor Naps and Historical Patterns

Before the widespread use of electricity, many people experienced two distinct sleep periods each night. This biphasic pattern—sleeping for a few hours, waking for activities, and then returning to sleep—can still be seen in some nomadic and hunter-gatherer societies.

In Scandinavian countries, unique sleep practices include:

• Encouraging babies and infants to nap outdoors, even in winter, for the health benefits of fresh air
• Daycares often have scheduled outdoor nap times

Perceptions of how much sleep is needed vary widely by culture, shaped by beliefs about rest and societal pressures. People also tend to sleep more during periods of stress.

Egypt: Cooling Techniques and Traditional Sleep Cycles

In Egypt, some people sleep on the floor and may soak blankets before bed to stay cool as the water evaporates overnight. Historically, nomadic and hunter-gatherer groups often practiced biphasic sleep, waking in the middle of the night for chores or to tend fires.

Monophasic sleep—one long nightly rest—became common only after the advent of artificial lighting. Nevertheless, many cultures still observe older, more flexible sleep patterns.

Canada: Modern Sleep Environments

In Canada and many Western countries, ideal sleep conditions typically include:

• Dark rooms
• Soft bedding
• Temperature-controlled environments

However, these preferences are not universal. Research in 2026 continues to show that sleep habits and beliefs about healthy rest differ greatly around the world.

Other global sleep customs include:

• Midday siestas in Latin America and the Mediterranean to avoid the heat and recharge after lunch
• Office workers in parts of Asia taking short naps during the workday to maintain alertness and productivity

South India: Early Bedtimes and Cultural Traditions

South India comprises five states: Tamil Nadu, Karnataka, Andhra Pradesh, Goa, and Kerala. The region is known for its diverse cultures, festivals, cuisines, and religious practices, including Hinduism, Islam, Jainism, and Buddhism.

Common sleep-related traditions in South India include:

• Early bedtimes
• Eating a variety of dishes such as rice, fish, coconut milk, and spices, often served on banana leaves
• Following feng shui principles, such as keeping mirrors away from beds

Botswana: Flexible Sleep Schedules and Natural Environments

Botswana, a landlocked country in Southern Africa, is known for its vast Kalahari Desert, the Okavango Delta, and abundant wildlife. Its people include both urban residents and traditional hunter-gatherer communities.

Key facts about Botswana's sleep habits:

• Flexible sleep schedules, with some communities sleeping at different times of day and night
• Inclusion of prayer or meditation in bedtime routines

Botswana is also recognized for its conservation efforts and rich natural reserves, such as Chobe National Park and Moremi Game Reserve.

Frequently Asked Questions

Why do sleep habits differ between countries?

Sleep habits vary due to cultural beliefs, climate, work schedules, access to electricity, and historical traditions. These factors influence when, where, and how long people sleep in different regions.

What is biphasic sleep?

Biphasic sleep refers to sleeping in two separate periods during the night, with a wakeful interval in between. This was common before artificial lighting and is still practiced in some traditional societies.

Why do some cultures nap during the day?

Midday naps, or siestas, are common in regions with hot climates, such as Latin America and the Mediterranean. Napping helps people avoid the midday heat and restore energy for the rest of the day.

Is it normal to sleep outside in cold climates?

In Scandinavian countries, it is common for babies and young children to nap outdoors, even in winter. This practice is believed to promote better sleep and health.

How has modern technology changed sleep habits?

The widespread use of artificial lighting and electronic devices has shifted sleep patterns, often leading to later bedtimes and shorter sleep durations in many countries.
