Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process.

With the advent of practical steam power, ceiling fans could finally be used for ventilation. Reid installed four steam-powered fans in the ceiling of St George's Hospital in Liverpool , so that the pressure produced by the fans would force the incoming air upward and through vents in the ceiling.
The suprachiasmatic nucleus (SCN) regulates melatonin and temperature and typically produces melatonin at night. Melatonin informs the body when it is time to sleep. When circadian cycles become disrupted (due either to too little light or too much light at the wrong time of day), melatonin is produced at disrupted times. This causes an ...
