How spending time in a sauna can improve rest and longevity

Spending time in heated environments, like a sauna, has been linked to lasting benefits for overall health. Research has shown that heat exposure can reduce the risk of some chronic diseases and improve sleep quality. In a recent interview with Fox News Digital, Todd Anderson, co-founder of Dream Performance & Recovery and host of the “Beat the Heat” podcast, shared some lesser-known effects of spending time in a sauna.

Anderson emphasized that saunas are not just for relaxation but can also be used as a tool for longevity. Studies have shown that increased sauna bathing is associated with a reduced risk of sudden cardiac death, fatal coronary heart disease, fatal cardiovascular disease, and all-cause mortality. Participants in a global sauna survey reported improvements in mental well-being and sleep, with few adverse effects.

One of the surprising benefits of heat exposure is its positive impact on sleep. Anderson explained that when the body heats up before sleep, the blood vessels open, allowing for better circulation to the extremities. While it may seem counterintuitive, raising the body temperature before sleep actually helps the body cool down faster, leading to higher quality sleep.

In addition to improving sleep, exposure to heat can boost the immune system. Dr. Roger Seheult, a critical care physician, highlighted that viruses do not fare well in high temperatures, and the body’s natural response to fighting a bug is to spike a fever. Methods like steam saunas can raise the body’s natural temperature and help kill off viruses.

Apart from the health benefits, Anderson also mentioned the social aspect of sauna sessions, where lasting friendships can be formed. Saunas provide a space free from distractions where people can connect face-to-face and go through controlled adversity together, promoting a sense of community and connection.

Saunas have been popularized in many cultures for generations and are accessible to all. Anderson noted that saunas can be made with simple materials like scrap wood and cheap heating options. In countries like Finland, saunas are a part of everyday life, with nearly every household having a sauna.

While saunas are generally safe for most people, it’s important to practice proper sauna etiquette and be aware of potential risks. Individuals with uncontrolled high blood pressure or heart disease should consult their doctors before participating in sauna sessions. It’s also important to stay hydrated, avoid alcohol and medications that may impair sweating, and not overstay in the sauna for more than 15 to 20 minutes.

In conclusion, spending time in a sauna can have numerous health benefits, including improved cardiovascular health, better sleep, and a boosted immune system. Saunas offer a unique opportunity for relaxation, connection, and overall well-being, making them a valuable addition to a healthy lifestyle.
