Sunlight matters during the coronavirus pandemic for two reasons: research discussed at the time suggested that sunlight degrades the virus on surfaces and in the air, and sun exposure drives the vitamin D production that supports a healthy immune system. In this Physical Friday, recorded during the 2020 lockdown, I talk through what was being reported about sunlight and the virus, and why getting outside, responsibly and at a distance, was one of the best things you could do for body and mind. This is an audio episode, so press play and follow along.

At the time this episode was recorded in April 2020, research being discussed publicly suggested that sunlight, along with heat and humidity, degraded the virus on surfaces and in the air more quickly than dark indoor conditions. I am not a doctor or a scientist, and in the episode I am careful to talk about this as reporting from that moment rather than medical advice. Listen to the episode for the full conversation in its 2020 context.
Sun exposure on your skin drives vitamin D production, and vitamin D plays a well-established role in supporting normal immune function. Many people, especially those working indoors, run low on it. During a lockdown, when stress is high and routines are gone, time outside in the sun is a simple, free habit that supports your immune system, your sleep, and your mood all at once. That trifecta is why I built an episode around it.
Following the guidance at the time, outdoor exercise with proper distance from other people was widely considered one of the lower-risk ways to stay active, and in many places it was explicitly allowed during lockdowns. Fresh air, sunlight, and movement together do more for you than any one of them alone. The key is making good choices, keep your distance, follow your local rules, and do not turn your workout into a crowd.
Morning sunlight anchors your circadian rhythm, the internal clock that tells your body when to be alert and when to wind down. Getting bright light early in the day helps you fall asleep easier at night, and better sleep improves recovery, mood, and immune function. In a lockdown, when days blur together, deliberate morning sun is one of the cheapest tools available for keeping your head right and your body recovering.
I am not a doctor, so I keep this general: regular, moderate sun exposure short of burning is the idea, and even fifteen to thirty minutes outside makes a difference in how you feel. Pair it with your workout, a walk, or your morning coffee so it happens automatically. If you have specific concerns about skin or vitamin D levels, that is a conversation for your physician, and I say the same thing in the episode.
In April 2020 everyone was locked indoors, scared, and glued to the news, and the reporting about sunlight and the virus caught my attention because it pointed in the same direction as everything I already believed about health: get outside. I am not a scientist, and I am careful in the episode to keep the line between reporting and advice. Press play in the player above to hear it in context.

Physical Friday is about the whole system, training, sleep, nutrition, and recovery, and sunlight touches all of it. It drives vitamin D, anchors sleep, lifts mood, and makes outdoor training possible. For fishing guides who live in the sun, the lockdown was the strange experience of suddenly losing it. I get into the bigger picture in the episode.
The goal is regular, moderate sun, not turning yourself into a lobster on day one. I talk through simple habits, morning light, outdoor workouts, daily walks, that stack the benefits without the burn, and why consistency beats heroics here just like it does in training. The details are in the episode, so press play in the player above.
This episode is a snapshot of April 2020, a strange moment when the simplest health advice in the world, go outside and get some sun, suddenly felt revolutionary. The science conversation has moved on, but the habit is still gold.
