Eight Causes Of Night Sweat
- Menopause -- The hot flashes that accompany the menopausal transition can occur at night and cause sweating. This is a very common cause of night sweats in women around the time of menopause.
- Idiopathic hyperhidrosis -- Idiopathic hyperhidrosis is a condition in which the body chronically produces too much sweat without any identifiable medical cause.
- Infections -- Classically, tuberculosis is the infection most commonly associated with night sweats. However, bacterial infections, such as endocarditis (inflammation of the heart valves), osteomyelitis (inflammation within the bones), and abscesses all may result in night sweats. Night sweats are also a symptom of AIDS virus (HIV) infection.
- Cancers -- Night sweats are an early symptom of some cancers. The most common type of cancer associated with night sweats is lymphoma. However, people who have an undiagnosed cancer frequently have other symptoms as well, such as unexplained weight loss and fevers.
- Medications -- Taking certain medications can lead to night sweats. In cases without other physical symptoms or signs of tumor or infection, drug side effects are often determined to be the cause of night sweats. Antidepressantmedications are a common type of drug that can lead to night sweats. All types of antidepressants can cause night sweats as a side effect, with a range in incidence from 8% to 22% of persons taking antidepressant drugs. Other psychiatric drugs have also been associated with night sweats. Medicines taken to lower fever such as aspirin and acetaminophen can sometimes lead to sweating. Other types of drugs can cause flushing, which, as mentioned above, may be confused with night sweats. Some of the many drugs that can cause flushing include:
- niacin (taken in the higher doses used for lipid disorders)
- tamoxifen
- hydralazine
- nitroglycerine
- Viagra.
7. Hormone disorders -- Sweating or flushing can be seen with several hormone disorders, including pheochromocytoma,carcinoid syndrome, and hyperthyroidism.
8. Neurologic conditions -- Uncommonly, neurologic conditions including autonomic dysreflexia, post-traumatic syringomyelia,stroke, and autonomic neuropathy may cause increased sweating and possibly lead to night sweats.

How An Aero plane Flies ?
Essentially there are 4 aerodynamic forces that act on an airplane in flight; these are lift, drag, thrust and weight (i.e. gravity).
In simple terms, drag is the resistance of air molecules hitting the airplane (thebackward force), thrust is the power of the airplane's engine (theforward force), lift is the upward force and weight is the downward force. So for airplanes to fly and stay airborne, the thrust must be greater than the drag and the lift must be greater than the weight(so as you can see, drag opposes thrust and lift opposes weight).
This is certainly the case when an airplane takes off or climbs. However, when it is in straight and level flight the opposing forces of lift and weight are balanced. During a descent, weight exceeds lift and to slow an airplane drag has to overcome thrust.
The picture below shows how these 4 forces act on an airplane in flight:
