Fresh air typically has more oxygen than air which has collected indoors. With these greater levels, you get better circulation and a healthier brain function, helping you feel calmer and clearer of mind, and, therefore, more likely to sleep.
“We also know there are a lot of positive associations between fresh air and relaxation, and when we feel relaxed and comfortable in our environment, we're more likely to feel sleepy.” A slight drop in body temperature can also prompt tiredness, Dautovich says.
Your body is trying to keep cool
“Your heart rate and metabolic rate go up when you sweat,” says Dr. Badgett. Your metabolism uses calories from foods and drinks to fuel body functions like breathing and blood circulation. When you're hot, your blood vessels expand and send more blood to your skin's surface.
A recent study published in the journal Indoor Air found that when people slept in rooms with ventilation—either with an open window or open door—compared to an unventilated room, their sleep improved, they woke up fewer times per night, and carbon dioxide levels in the room were lower.
How long should I spend outside to get the benefits of fresh air? Studies show that just 20–30 minutes outdoors significantly reduces stress and boosts mood. Aim for at least 30 minutes of fresh air daily to get the physical health benefits.
It's spending 20 minutes in your local park three days per week, five hours in a nature preserve each month and three days immersed in the backcountry (think camping or hiking trip) once a year. It's called the 20-5-3 rule, and it's a science-backed formula that could revolutionize how we think about outdoor time.
Fresh air not only cleans your lungs, it can also boost your mood, lower your heart rate, increase energy levels and even improve digestion (yes, that's right). Florence Nightingale knew the benefits of fresh air long before any scientific study.
CO2 levels that are higher than 1150 ppm will typically occur in bedrooms that are not fitted with a ventilation system and where windows and doors are closed. Above 2600 ppm: Insufficient ventilation—both sleep quality and next-day performance are adversely affected.
The brain is extremely sensitive to decreases in oxygen levels. Therefore when a person takes a walk outside, getting to breathe fresh outdoor air actually improves brain function, especially if a person is cooped up in an office most of the day.
The FSRI strongly recommends sleeping with your bedroom door closed for added protection, as part of your overall bedroom fire safety plan.
Study Impact: We found a significant, but complex, relationship between 25-hydroxyvitamin D and subjective sleepiness, as measured by the Epworth Sleepiness Scale, suggesting the possibility that Vitamin D deficiency may be a modifiable cofactor in the pathophysiology of excessive daytime sleepiness, sleep disorders, ...
Common causes of tiredness and fatigue include: not getting enough sleep or finding it hard to get to sleep (insomnia) an unhealthy lifestyle (such as having an unhealthy diet and not getting much exercise) stress, depression and dealing with life challenges, such as bereavement or looking after a new baby.
Studies show that spending as little as 20 minutes a day outside helps to reduce stress. Parks and other open space provide the perfect opportunity for a respite in your day. Fifty-eight percent of U.S. adults say they spend at least 30 minutes per day outside. One third spend more than an hour outside daily.
Sunshine can boost your vitamin d levels, as well as your serotonin levels – the body's happy hormone, but too much sun can actually leave you feeling sleepy, lethargic, sluggish and drained of energy. There are a number of reasons why the sun can make you tired. These include: Dehydration.
The brain is designed to monitor oxygen, so if there is a 3 or 4% drop in oxygen, your brain will sense the problem and wake you up just enough to restore your breathing. While this arousal helps to maintain oxygenation, it also sabotages your restorative rest by breaking your sleep cycle.
Research shows that exposing your lungs to fresh air, and the scents of flowers and plants, can help to relieve stress and anxiety. Oxygen is thought to affect the levels of serotonin released in the body, in turn, contributing to feelings of happiness and relaxation.
Reece says: "Getting out in the fresh air can help ease those feelings of stress, anxiety and low mood."
Walking outdoors is great exercise. “The changing terrain of a hike adds an extra boost for your muscles and cardiovascular system,” notes Dr. Dittus. Spending time in nature improves your circadian rhythms and helps you get better sleep.
“Studies have shown that spending just 15 minutes outside can reduce your cortisol level, the stress hormone in the body and boost the serotonin and dopamine level, the feel-good chemicals in the brain. It is a natural stress buster,” explained Susan Albers, PsyD, psychologist for Cleveland Clinic. Dr.

One of the warning signs of poor ventilation is a feeling of tiredness and sluggishness. Most put the mid-afternoon biscuit break (or Afternoon Tea) down to hunger or boredom, but it's actually more likely to be the effects of high CO2 levels in your office making you feel drowsy.
Natural Lighting
When deprived of natural light, our bodies may experience a deficiency in vitamin D, which is essential for strong bones, immune system function, and mental health. Lack of sunlight also hinders our ability to regulate our sleep-wake cycle, leading to imbalanced and irregular sleep patterns.
Your brain craves stimulation, and physical environment matters. That's why a 20-minute walk outside has been proven to channel focus and promote increased concentration as it gives your mind time to unwind from pressing matters and redirect to soak up new sensations.
