1) Cardiovascular Conditions

Individuals   with   cardiovascular   conditions   or problems    (hypertension    /    hypo    tension), congestive       heart       failure,       impaired coronary   circulation   or   those   who   are taking   medications,   which   might   affect blood      pressure,      should      exercise extreme    caution    when    exposed    to prolonged       heat.       Heat       stress increases   cardiac   output,   blood   flow, in   an   effort   to   transfer   internal   body heat   to   the   outside   environment   via the        skin        (perspiration)        and respiratory   system.   This   takes   place primarily   due   to   major   changes   in   the heart    rate,    which    has    the    potential    to increase   by   thirty   (30)   beats   per   minute for   each   degree   increase   in   core   body temperature.

2) Medications

Individuals    who    are    using    prescription drugs   should   seek   the   advice   of   their   personal   physician   or   a pharmacist   for   possible   changes   in   the   drugs   effect   when   the body    is    exposed    to    Far    infrared    waves    or    elevated    body temperature.    Diuretics,    barbiturates    and    beta-blockers    may impair   the   body’s   natural   heat   loss   mechanisms.   Some   over   the counter   drugs   such   as   antihistamines   may   also   cause   the   body to be more prone to heat stroke.

3) Children

The   core   body   temperature   of   children   rises   much   faster   than adults.   This   occurs   due   to   a   higher   metabolic   rate   per   body mass,     limited     circulatory     adaptation     to     increased     cardiac demands    and    the    inability    to    regulate    body    temperature    by sweating.   Consult   with   the   child’s   Pediatrician   before   using   the sauna.

4) Saunas & The Elderly

The   ability   to   maintain   core   body   temperature   decreases   with age.    This     is     primarily     due     to     circulatory     conditions     and decreased   sweat   gland   function.   The   body   must   be   able   to activate   its   natural   cooling   processes   in   order   to   maintain   core body temperature.

5) Alcohol / Alcohol Abuse

Contrary    to    popular    belief,    it    is    not    advisable    to    attempt    to “Sweat    Out”    a    hangover.    Alcohol    intoxication    decreases    a person’s   judgement;   therefore   they   may   not   realize   it   when   the body    has    a    negative    reaction    to    high    heat.    Alcohol    also increases   the   heart   rate,   which   may   be   further   increased   by heat stress.

6) Chronic Conditions

Diseases    Associated    with    a    Reduced    Ability    To    Sweat    Or Perspire:   Multiple   Sclerosis,   Central   Nervous   System   Tumours and    Diabetes    with    Neuropathology    are    conditions    that    are associated with impaired sweating.

7) Hemophiliacs

Individuals    Prone    To    Bleeding:    The    use    of    Infrared    saunas should be avoided by anyone who is predisposed to bleeding

8) Fever

Individuals should not use the sauna when they have a fever.

9) Insensitivity to Heat

An   individual   that   has   insensitivity   to   heat   should   not   use   a sauna.

10) Pregnancy

Pregnant   women   should   consult   a   physician   before   using   a sauna   because   foetal   damage   can   occur   with   a   certain   elevated of the body temperature.

11) Joint Injury

If   you   have   a   recent   (acute)   joint   injury,   it   should   not   be   heated for   the   first   48   hours   after   an   injury   or   until   the   hot   and   swollen symptoms    subside.    If    you    have    a    joint    or    joints    that    are chronically   hot   and   swollen,   these   joints   may   respond   poorly   to vigorous   heating   of   any   kind.   Vigorous   heating   is   strictly   contra- indicated    in    cases    of    enclosed    infections    be    they    dental,    in joints or in any other tissues.

12) Implants

Metal   pins,   rods,   artificial   joints   or   any   other   surgical   implants generally   reflect   Far   infrared   waves   and   thus   are   not   heated   by this   system,   nevertheless   you   should   consult   your   surgeon   prior to   using   an   Infrared   Sauna.   Certainly,   the   usage   of   an   Infrared Sauna   must   be   discontinued   if   you   experience   pain   near   any such    implants.    Silicone    does    absorb    Far    infrared    energy. Implanted    silicone    or    silicone    prostheses    for    nose    or    ear replacement   may   be   warmed   by   the   Far   infrared   waves.   Since silicone   melts   at   over   200°C   (392°F),   it   should   not   be   adversely affected   by   the   usage   of   Infrared   saunas.   It   is   still   advised   that you   check   with   your   surgeon   and   possibly   a   representative   from the implant manufacturer to be certain.
