- - - - Heat loss mechanisms
        
        Increase in sweat gland secretion = evaporative heat loss
        Increase rate and depth of respiration = evaporative heat loss
        Activated vasodilation of peripheral blood vessels = increase of radiation and convective heat loss :red_flag: ?
      - Heat gain (retention) mechanisms
        
        Vasoconstriction of peripheral blood vessels
        Counter-current heat exchange systems
        Convective and radiation losses are minimized :red_flag: ?
        
        Shivering Thermogenesis
        Increased muscle tone causes 'shivering'
        Involuntary muscular activity that augments metabolic heat production
        
        Non-shivering Thermogenesis
        The release of hormones to increase metabolic activity
        Adrenaline
        Increases metabolic activity in liver and skeletal muscles
        (Via promoting glycogen breakdown)
        Thyroid hormone
        Increases basal metabolic rate
