HEMLOCK VS. CEDAR

Hemlock Saunas

Hemlock, a type of wood known for its straight grain and uniform texture, is a popular choice for sauna construction. The light color and natural elegance of hemlock wood can add a touch of sophistication to any sauna room. In addition to its aesthetic appeal, hemlock is also highly durable and resistant to warping, making it an excellent choice for sauna enthusiasts seeking longevity and low maintenance.


One of the key advantages of hemlock saunas is their ability to retain heat efficiently. The dense nature of hemlock wood allows it to hold heat effectively, creating a consistent and comfortable sauna experience. Furthermore, hemlock is known for its minimal expansion and contraction in response to changes in temperature and humidity, making it a reliable choice for sauna construction.

Cedar Saunas

Cedar is another popular wood choice for saunas, prized for its distinctive aroma and natural resistance to decay and insects. The rich, reddish-brown hue of cedar wood adds warmth and character to any sauna space, creating a welcoming and inviting atmosphere. Beyond its visual appeal, cedar is renowned for its aromatic properties, which can enhance the sensory experience of sauna bathing.


In addition to its aromatic allure, cedar wood is naturally resistant to moisture, making it an ideal option for sauna construction. The natural oils present in cedar wood act as a protective barrier against moisture and humidity, reducing the risk of rot and decay. This inherent resistance to moisture makes cedar saunas a popular choice for outdoor and high-humidity environments.

Comparing Hemlock and Cedar Saunas

1. Heat Retention
Hemlock wood is known for its exceptional heat retention properties, ensuring that the sauna maintains a consistent and comfortable temperature. This makes hemlock saunas an excellent choice for those seeking a sauna experience with optimal heat distribution and retention. On the other hand, while cedar also offers good heat retention, it may not match the level of heat retention provided by hemlock. However, cedar's natural insulating properties make it an excellent choice for outdoor saunas or environments with fluctuating temperatures.
2. Aesthetic Appeal
Both hemlock and cedar saunas offer distinct visual appeal. Hemlock's light color and uniform texture exude a sense of natural elegance and sophistication, while cedar's rich, reddish-brown hue adds warmth and character to the sauna space. The choice between the two woods ultimately comes down to personal preference and the desired aesthetic for the sauna environment.
3. Aroma
Cedar's aromatic properties are one of its most distinctive features. The natural oils present in cedar wood release a pleasant, soothing aroma when heated, enhancing the overall sensory experience of sauna bathing. For individuals who value the aromatic aspect of sauna bathing, cedar may be the preferred choice. Hemlock, while lacking the strong aromatic qualities of cedar, offers a more neutral and understated scent, which may be preferable for those seeking a more subtle fragrance in the sauna.
4. Durability and Maintenance
Both hemlock and cedar are durable woods that can withstand the high temperatures and humidity levels present in saunas. Hemlock's minimal expansion and contraction make it a reliable and low-maintenance option, requiring less frequent upkeep. Cedar, with its natural resistance to decay and insects, also offers excellent durability. However, cedar may require more regular maintenance to preserve its natural properties, such as resealing or refinishing over time.

BENEFITS OF USING A SAUNA

1. Relieve stress

Not surprisingly, sauna bathers most frequently cite stress reduction as the number one benefit of sauna use. Medical studies often determine that stress in our daily lives can negatively affect our health. In fact, the vast majority of disease (i.e. heart disease) is at least partially stress-related. Heat bathing in a sauna provides stress relief in a number of ways. It’s a warm, quiet space without any distractions coming from the outside. The heat from the sauna relaxes the body’s muscles, improves circulation and stimulates the release of endorphins. Endorphins are the body’s all-natural “feel good” chemical, and their release provides a truly wonderful “after sauna glow.”.

2. Relax muscles and soothe aches/pains in both muscles and joints

Under the high heat provided by a sauna, the body releases endorphins. Endorphins can have a mild, enjoyable “tranquilizing effect” and the ability to minimize the pain of arthritis and muscle soreness other from, say, an intense physical workout. Body temperature also rises from the heat of the sauna.. This causes blood vessels to dilate, therefore increasing blood circulation. This increased blood flow in turn speeds up the body’s natural healing process via soothing aches and pains and/or speeding up of the healing of minor bruises or cuts. After participating in physical sports, use the heat and/or steam of a sauna to promote muscle relaxation by helping to reduce muscle tension and eliminate lactic acid and/or other toxins that may be present.

3. Flush toxins

Many – if not most – of us do not actively sweat on a daily basis. Deep sweating, however, has multiple proven health benefits. Benefits derived from a deep sweat can be achieved via regular sauna bathing.Due to the heat of a sauna, the core body temperature begins to rise. The blood vessels then dilate, causing increased blood flow. As heat from the blood begins to move toward the skin’s surface, the body’s nervous system then sends signals to the millions of sweat glands that cover the human body. As the sweat glands become stimulated, they produce sweat. Sweat production is primarily designed to cool the body, and is composed of 99% water. However, deep sweating in a sauna can help reduce levels of lead, copper, zinc, nickel, mercury and chemical – which are all toxins commonly absorbed just from interacting with our daily environments.There is no shortage of books from Doctors and practitioners, who describe the benefits of detoxifying our bodies regularly. As many doctors will agree, a big reason for the popularity of saunas is that they are one of the best ways to detoxify our bodies.

4. Cleanse the skin

Heat bathing is one of the oldest beauty and/or health strategies in terms of cleansing one’s skin. When the body begins to produce sweat via deep sweating, the skin is then cleansed and dead skin cells are replaced – keeping your skin in good working condition.Sweating rinses bacteria out of the epidermal layer and sweat ducts. Cleansing of the pores has been shown to improve the capillary circulation, while giving the skin a softer-looking quality. Bathing skin in sweat on a fairly regular basis, therefore deters collagen breakdown that can ultimately result in wrinkles and sags. By continually flushing body waste through individual cells, one eventually brings back vitality, tone and a healthy glow to the skin. Sauna usage is certainly not a cure for acne, but it can very often help – due to the deep cleansing it provides from a deep sweat (that is, cleaning the pores from the very inside out – instead of just cleaning the top of the skin).

5. Induce a deeper sleep

Research has shown that a deeper, more relaxed sleep can result from sauna use. In addition to the release of endorphins, body temperatures, which become elevated in the late evening,fall at bedtime. This slow, relaxing decline in endorphins is key in facilitating sleep. Numerous sauna bathers worldwide recall the deep sleep experiences that they feel after bathing the the calming heat of a sauna.

6. Help burn calories

Outlandish claims are often made by some sauna sellers (primarily those who sell infrared saunas) to promote saunas as an end-all weight loss tool. While some individuals may experience high amounts of calorie burn at first – particularly those individuals in poor shape to begin with – over the long term, saunas are simply treated as one of many tools in our arsenal when it comes to burn additional calories.The sweating process itself requires a notable amount of energy. That energy is derived from the conversion of fat and carbohydrates in a bodily process that burns up calories. According to U.S. Army medical research (Ward Dean, M.D.), “A moderately conditioned person can easily sweat off 500 grams in a sauna in a single session, consuming nearly 300 calories in the process.”The body consumes said calories due to the acceleration of heart activity (the cardiovascular section). As heart activity increases and as these processes demand more oxygen, the body begins to convert more calories into usable energy.
