While the COVID-19 pandemic taught the world to stay indoors to avoid infections, this advice is not new to cancer patients. Long before self-quarantine became common, cancer patients were advised to avoid crowded places and eating out due to a compromised immune system.
For many, this means staying indoors at all times. While this is a necessary precaution, prolonged confinement can lead to isolation and negatively impact both physical and mental health.
Even if social interaction remains limited, simply being outdoors — in sunlight and fresh air — can have profound benefits. Many cancer patients are now encouraged to spend safe, solitary time in nature when possible.
What can the outdoors do for you?
Only venture out if you can maintain social distancing and follow safety precautions like wearing masks, gloves, and sanitizing. Also assess the cleanliness and safety of the outdoor space — polluted or crowded areas are best avoided.
If you have access to a clean park, garden, or even a balcony, spending time there regularly can be highly beneficial. Here’s how:
Vitamin D
Exposure to mild sunlight helps the body produce vitamin D, which it cannot make on its own. Just 15 minutes of daily sun can strengthen bones and reduce the risk of osteoporosis.
Sunlight also boosts serotonin levels, improving mood and reducing the risk of anxiety, depression, and seasonal affective disorders.
Melatonin
Sunlight helps regulate the production of melatonin, the hormone that controls your sleep-wake cycle. Exposure to natural light during the day and darkness at night helps maintain a healthy sleep pattern and reduces insomnia.
Endorphins
Being outdoors naturally encourages light physical activity — walking, stretching, climbing stairs — which releases endorphins. These hormones reduce stress and pain, improve blood circulation, stamina, and appetite.
Many patients notice improved nutrition intake after spending time outside due to a better appetite.
Remember: Stay hydrated, carry water or juice, and stop at the first sign of discomfort or fatigue.
Oxygen
Fresh air and gentle outdoor exercise improve breathing and oxygen intake — vital for overall health and cellular function.
If you prefer to sit, practice deep breathing exercises. These enhance lung function and promote relaxation.
Many cancer patients who safely enjoy the outdoors report looking forward to this part of their day. Making it a daily routine helps ensure consistency and improves overall well-being while staying safe.
