      <abstract>
        <p>Walking is the best possible exercise to promote fitness. However, ambient temperature has an impact on walking regimen and performing exercise in different biological conditions can be challenging tasks. For example, both cold and hot temperatures can impair walking performance. In fact, walking in different cold and warm ambient can be challenging physical activity.  But suitable sport wears and drinks during walking performances can protect of the body in cold and warm conditions. In this relation, different cold and warm weathers although can challenge walking performance but they account for opportunities for body to adapt to the different seasonal conditions.  Thus, performing  regular walking in different cold and warm weathers can help individual to stay active as well as fit. </p>

      <title>Introduction</title>
      <p>Performing any type of sport in various conditions can yield several health benefits in human body. An optimal body health promotes any good work in different aspects. This is because, executing regular physical activity can result in continuous physical fitness as well as readiness <xref ref-type="bibr" rid="ridm1842900700">1</xref>.  </p>
      <p>Walking is the best possible exercise which simply can be performed with minimum cost of energy in any environments. Particularly, walking accounts                 for healthiest kind of aerobic exercise as all body segments contract in order to move forward or backward directions . More bodily movements during walking exercise are linked with more healthy activities that can be accompanied with  good - health and prosperousness <xref ref-type="bibr" rid="ridm1842902284">2</xref><xref ref-type="bibr" rid="ridm1842913420">3</xref>.                  </p>
      <p>Walking workouts can be accomplished according to any volume and acceleration depending on the associated biological territory at which walking is being performed. In regards to this, walking can be categorized in habitual at any pace or structural at predetermined pace. Further, the type of walking surface aligned with gravity can change walking pace and oxygen uptake during walking, so that different type of walking demands different level of energy consumptions (higher or lower) <xref ref-type="bibr" rid="ridm1843001468">4</xref><xref ref-type="bibr" rid="ridm1842762092">5</xref>.   </p>
      <p>Therefore, various walking type present different health benefits in terms of efficiency and effectiveness. Uphill-walking uses for weight - loss program owing to the high level of energy consumption and downhill-walking use to strengthen the musculature due to gravity assistance <xref ref-type="bibr" rid="ridm1842759500">6</xref><xref ref-type="bibr" rid="ridm1842746676">7</xref>. </p>
      <p>Nonetheless, performing exercise such as ordinary walking in different biological conditions can be a challenging  task and in this short - review the potential factors which can impact on walking performance will be evaluated in brief.  </p>

        <title>Walking in Cold and Warm Biological Environments </title>
        <p>Physiologically performing walking in             non-identical conditions demands different physical bodily efforts. In regards to this, the biological adaption of the different kind of environments including warm or cold is the main determinate in movement‘s executions (i.e. walking performances) per each condition <xref ref-type="bibr" rid="ridm1842752508">8</xref>.</p>
        <p>Greater body temperature, heart rate, higher circulation, and higher ventilator responses owing to the thermal stress is required while walking in heat conditions. The hot weather dramatically increases the breathing frequency, central and cardiovascular fatigues and oxygen transformations to upper and lower body plus whole skin per second while walking                   locomotion <xref ref-type="bibr" rid="ridm1842747108">9</xref>. Although, the individual adaptions to the environment variations differ between one to another. Indeed, any body movement can be resilience to varied conditions and exercise in hot weather although is challenging  work but account for an opportunity to kind of body adaption (i.e. cardiovascular and respiratory adaptions) to heat condition. For example, avoiding intensive physical exertion and performing moderate any type of activity regularly such as systematically walking at moderate pace can be an effective strategy to adapt to the hot weather. Drinking adequate fluid and water can help to prevent dehydration and losing body fluid while walking in heat climate. Many people do not drink enough while performing physical activity so that they are not able to have a free-flowing movement in warm weather <xref ref-type="bibr" rid="ridm1842741140">10</xref>. Therefore, having a regular bottle of water while walking can be a good help to maintain body fluid and electrolytes  in warm climate . Indeed, drinking enough water (or any proper sport drink) while walking in heat situation reduces the risk of exhaustion and physiological strain in individual over time <xref ref-type="bibr" rid="ridm1842738764">11</xref>. </p>
        <p>Walking regimen in cold weather also may seems an adventure since cold weather is align  with different challenges ,  but it is gain an opportunity for people to get fit and stay active as minimum of health benefit . Cold weather can lead pain, stiffness or cramp and shivering (involuntary muscle contraction) in musculoskeletal – system <xref ref-type="bibr" rid="ridm1842742508">12</xref>. This is because, exposure to the cold temperature can cause muscles consume more oxygen uptake while losing more heat and energy that easily can be compensated by wearing proper clothes   and drinks during any movement and in part walking <xref ref-type="bibr" rid="ridm1842720436">13</xref>. </p>
        <p>Cold environment can reduces walking pace                    and velocity which can be recompensed with                  longer - duration of walking performance, so that cold weather condition dose not actually account for a barrier for performing any physical movement including walking exercise. Walking in cold weather as causes more energy consumptions and calorie intakes, can also lead to the more ideally body mass index (BMI) and body shape in individual who are more active and intend to walk more in cold temperature <xref ref-type="bibr" rid="ridm1842714172">14</xref>.</p>

        <title>Glossary</title>
        <p>In summary it seems ambient temperature has functional impacts on any kid of exercise in part simple walking. At the first look, different ambient conditions may impair physical activations. For example both cold and hot temperatures can result in hypoxia that can inhibit prolong exercise in different individual. In this relation, performing regular exercise such as 30 minutes walking per each day at moderate pace can help to stay fit as well as active. Proper sport wears and drink are also good preventive strategies to combat sedentary lifestyle in different conditions. Performing regular exercise such as walking in various seasonal warm or cold weather physiologically can be a challenge task whitest at the same time can be an opportunity to adapt with any conditions to stay fit  and healthy which of course depends on the individual determinations. </p>
